The catalyst is systematically characterized to investigate the morphology, crystal structure and chemical composition, and the findings demostrated that MoO3 catalyst is successfully synthesized. The degradation mechanism is also illustrated by the density functional theory (DFT) calculation. The degradation experiments confirm that MoO3 catalyst exhibits excellent catalytic performance in CWAO, and the removal rate of TOC (Total Organic Carbon) and COD (Chemical Oxygen Demand) is achieved to more than 93%. The catalyst doses, reaction temperature and reaction time have a significant impact on the removal of pollutants. The degradation process of pollutants in CWAO could be satisfactorily fitted by the second-order kinetics. Besides, MoO3 displays a favorable stability as CWAO catalyst. DFT calculation illustrates that MoO3 catalyst is a typical indirect band gap semiconductor. Moreover, the high temperature environment provides the thermal excitation energy, which favors to the free electrons nearing Fermi level to escape the material surface, and excites them to the conduction band, then directly reduces the pollutants in CWAO. These findings demonstrate that MoO3 can be used as an efficient and excellent catalyst for CWAO of pharmaceutical wastewater. 48 C. Chen, T. Cheng, L. Wang, Y. Tian, Q. Deng, Y. Shi produces hydroxyl radical (OH) with strong oxidation ability under the reaction conditions of high temperature and high pressure, electricity, sound, light irradiation, and catalyst. By utilizing the advanced oxidation technology, the refractory organic substances of macromolecules could be oxidized into low toxic or non-toxic small molecular substances. Schrank et al. use diverse advanced oxidation techniques of UV (Ultraviolet Light), TiO2/UV, O3 and O3/UV to degrade pollutants in tannery wastewater; it demonstrates that the biodegradation of wastewater is enhanced through oxidation, and the toxicity of pollutants is also decreased (Schrank et al, 2004). Hofman-Caris et al. removed pharmaceuticals from wastewater effluent and dissolved non-biodegradable organic matter by advanced oxidation technique. The results suggest that advanced oxidation techniques could remove multiple different pharmaceuticals and humic acid to a large extent (Hofman-Caris et al., 2017). Wet air oxidation (WAO) technology is a kind of advanced oxidation technology. It can oxidize organic substances in wastewater to small molecules or inorganic matter under the condition of high temperature (120–320°C) and high pressure (0.5 ~20 MPa). Gaseous oxygen is utilized as oxidant in this reaction. Moreover, it can treat wastewater with refractory substances, and be highly evaluated by many researchers due to its simple operation and easy industrialization. However, the WAO technology requires high temperature, and the co","PeriodicalId":48950,"journal":{"name":"Archives of Environmental Protection","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79302659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In RBBR-containing post-culture liquids, there were determined the degree of RBBR decolorization, horseradish peroxidase-like, superoxide dismutase-like, and xylanase activities, and the concentrations of low-molecular phenolic compounds. The study results demonstrated that Trichoderma asperellum, T. harzianum, and T. lixii strains isolated from compost containing larger amounts of easily available lignocellulose fractions, i.e. grasses, exhibit higher RBBR decolorization effi ciency ranging from 0.3 to 62% than T. citrinoviride strains isolated from compost II, which contained greater quantities of hardly degradable lignocellulose. The decolorization of remazol blue R by the investigated Trichoderma strains intensifi ed signifi cantly with the increase in peroxidase activity and it was correlated with a decline in the content of low-molecular phenolic compounds. The dynamics of changes in the horseradish peroxidase-like, superoxide dismutase, and xylanase activities in the aqueous post-culture liquids of the investigated fungal strains depended largely on the duration of the culture. Given their ability to adapt to water environments, e.g. wastewater, and to decolorize and detoxify the RBBR anthraquinone dye, Trichoderma fungi can be used for bioremediation of such environments. Removal of a textile dye (RBBR) from the water environment by fungi isolated from lignocellulosic composts 13 (2012). The ability to biodegrade RBBR is also tested in micromycetes, as reported by Jasińska et al. (2012) and Noman et al. (2019), in Staphylococcus sp. bacteria (Velayutham et al. 2018), and in bacterial and/or fungal consortia (Khudhair et al. 2015; Lade et al. 2016). Microorganisms that grow well in the water environment are especially valuable organisms playing an important role in the biodetoxifi cation of colored industrial wastewater. They include representatives of the Trichoderma genus, which were shown by Grabińska-Łoniewska (2004) as hydrophilic well-growing and well-sporulating fungi in water environments including wastewater. Among them, fungi isolated from natural environments that are rich in lignocellulosic organic matter seem to be very promising in this regard. There is a relationship between the ligninolytic abilities of fungi and the abilities to biodegrade other aromatic compounds, including colored ones, as reported by Ulmer et al. (1984). López et al. (2006) and Chamuris et al. (2000) suggest that micromycetes isolated from composts can be potential wood lignocellulose degraders. In turn, Ryazanova et al. (2015) have demonstrated that, besides their ability to decompose cellulose, Trichoderma fungi have the ability to degrade lignin.

This water contains organic contaminations that are by-products of the fermentation process. Part of them are volatile compounds, which migrate through the two-stage RO system. The aim of this work was to estimate the Fenton and Fenton-like reactions suitability to decrease the concentration of the organic compounds in the evaporative water from yeast slurry concentration. There were determined the conditions, which have a signi fi cant in fl uence on the achievement of the highest mineralization of the organic compounds. Abstract: Evaporative water from yeast slurry concentration is acidic, low mineralized and contains large amounts of dissolved organic contaminants. The treatment of evaporative water from yeast slurry concentration by Fenton (Fe(II)/H 2 O 2 ) and Fenton-like (Fe(III)/H 2 O 2 ) reactions has been studied. The processes in terms of system variables have been compared: catalyst and oxidant doses, initial pH, temperature of reaction, and the reaction kinetic. For determination of mineralization ef fi ciency the total organic carbon (TOC) in water before and after reactions was measured. The Fenton reaction was more ef fi cient for mineralization of organic compounds: the highest ef fi ciency of TOC removal was 45–50%, while for the Fenton-like it was 20–30%. The pH adjustment of evaporative water in the range of 2–5 did not change the ef fi ciency of treatment. Temperature of 30°C was the most favorable for both reactions. The Lumped Kinetic Model fi tted very well the experimental results. The reaction rate analysis indicated that the rate of direct mineralization of organic compounds is similar to the rate of its oxidation to organic intermediates, its selectivity factor was more favorable to the Fenton reaction. The strong correlation between chemical oxygen demand (COD) and TOC in evaporative water after the Fenton and Fenton-like reactions has been determined, providing a simple tool for calculating COD on the basis of values of TOC measurement.","PeriodicalId":48950,"journal":{"name":"Archives of Environmental Protection","volume":"112 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73039236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of high pollution loads, many researchers treat vinasse before decolorization. The vinasse is centrifuged, fi ltered or anaerobically treated (Tiwari and Gaur 2014, Boopathy and Senthilkumar 2014, Tondee and Sirianuntapiboon 2008, Ravikumar et al. 2013). Other researchers did not use wastewater from distilleries but synthetic melanoidins, which are easier to decolorize (Agnihotri 2015, Santal et al. 2016). In our study we used sugar beet molasses vinasse without pretreatment. Moreover, this kind of wastewater has not been tested by other researchers because they have focused on cane vinasse (Espana-Gamboa 2015, Shukla 2014). The aim of our study was to optimize the medium composition and the process conditions of sugar beet molasses vinasse decolorization by Lactobacillus plantarum MiLAB393. The optimization of the concentrations of glucose and yeast extract using experimental design (DOE) was made at the stage of shake-fl ask cultures. During the batch experiment, the Abstract: Sugar beet molasses vinasse is a high-strength distillery wastewater. It contains colored substances which signifi cantly aff ect the degree of pollution and toxicity of vinasse. This study aimed to optimize the medium composition and the process condition of sugar beet molasses vinasse decolorization by Lactobacillus plantarum MiLAB393. The research was conducted in two stages: the shake-fl ask stage in the 250 cm 3 Erlenmeyer fl asks and the batch experiments in the 5 dm 3 working volume stirred-tank bioreactor. During the study, the concentrations of glucose and yeast extract were optimized using experimental design of experiments (DOE). The infl uences of the initial value of pH and pH control, temperature, stirrer speed and glucose concentration on decolorization were tested. The highest color reduction of 24.1% was achieved for an experiment in which 24.93 g/dm 3 of glucose was added to the medium and stirrer speed was 200 rpm. This effi ciency of 30% v/v sugar beet molasses vinasse decolorization was obtained at non-controlled pH 6.0 and at 35.8°C. It was found that pH control determines vinasse decolorization. When the pH was controlled, decolorization did not exceed 9%. The glucose and yeast extract concentration and the stirrer speed have a great infl uence on the process. Changes in these parameters may increase biomass growth while decreasing the decolorization.","PeriodicalId":48950,"journal":{"name":"Archives of Environmental Protection","volume":"80 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86235970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, bulk deposition can be considered useful for tracking the migration path of substances from different sources. The aim of the study carried out at five measurement points in Zabrze and Bytom was to assess the content of selected physico-chemical parameters in bulk deposition. Samples were collected continuously from November 2019 to November 2020. In the collected samples the following were determined: COD, pH, conductivity, dissolved organic carbon, inorganic carbon and total carbon; inorganic anions (Cl - , SO 42, NO 3-, NO 2-, Br - , PO 43) and cations (Li + , Mg 2+ , Ca 2+ , Na + , K + , NH 4+ ), metals and metalloids (Mn, Ni, Co, Cu, Zn, As, Cd, Pb, Cr, and Fe), and carboxylic acids (formic, acetic, oxalic). The obtained test results were statistically processed using Excel, and the normality of data distribution was verified by Shapiro-Wilk test.
