The effects of temperature on HF corrosion of different water-cooled wall pipes in 0.2% HF were investigated. Corrosion kinetics curve was obtained by calculating the mass increase due to corrosion. The microscopic morphology and physical phase composition of water-cooled wall pipes after HF corrosion were analyzed. The corrosion resistances of the two water-cooled wall pipes decrease with increasing the temperature. The corrosion weight gain curves of 15CrMoG and 20G at 550 ℃ are ΔW1.9144 = 0.2100t and ΔW1.8356 = 0.1344t, respectively. The average corrosion rates of 15CrMoG and 20G are 0.0177 and 0.0125 mg/(cm2·h), respectively. The corrosion resistance of 15CrMoG is superior compared to 20G.

Researches showed that: (1) The removal rates of COD, NH4+-N and TN were significantly positively correlated with temperature (r = 0.99, 0.96, 0.97), the lowest removal rates were 83.16%, 95.68%, 58.7% ((8-11) ℃), the highest values were 92.67%, 98.27%, 70.96% ((22-25) ℃), respectively. (2) At a temperature range of 22-25°C, the microbial community exhibited the highest levels of abundance, diversity, and uniformity. Notably, Proteobacteria dominated this temperature range with a relative abundance of 79.72%. Furthermore, temperature positively correlated with the majority of dominant bacterial species, suggesting that conditions at 22-25°C are highly conducive to the growth of most bacterial communities. Among these, Limnohabitans, Alsobacter, and Candidatus_Aquirestis, which possess key functions in denitrification and nitrogen removal, displayed significantly higher abundances. It explains the positive correlation between temperature and removal rates of COD, TN and NH4+-N from microbial population's perspective. Thus, the best temperature for repairing black-smelly water is (22-25) ℃.

The measurement of the air quality index (AQI) depends on various environmental situations, such as emissions, dispersions, and chemical reactions. This paper developed the Internet of Things (IoT)-based Deep Learning (DL) technique for predicting air quality. Initially, the IoT simulation is performed, where the nodes receive input data. The routing technique is used to identify the best route toward the Base station (BS). The proposed Tangent Two-Stage Algorithm (TTSA) is used in the routing mechanism. For AQI prediction, the time series data is transmitted to the BS. The Z-score normalisation is employed to neglect the unessential data. Furthermore, feature indicator extraction is employed to extract the relevant feature indicators. The Deep Feedforward Neural Network (DFNN) is used to predict air quality. Furthermore, the proposed Fractional Tangent Two-Stage Optimisation (FTTSA) is employed for the training process of DFNN. Moreover, metrics such as energy, time, and distance are used to evaluate the routing process, and superior results such as 0.979J, 0.025s and 0.196 m are obtained. Furthermore, the AQI is predicted by metrics like root mean square error (RMSE), R-squared (R2), mean square error (MSE), and mean absolute percentage error (MAPE), whereas the superior values such as 0.602, 0.598, 0.362, and 0.456 are attained.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"1892-1908"},"PeriodicalIF":2.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142521450","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 this study, three CWs were established to evaluate the effect of iron scraps and iron-carbon as substrates on pollutants removal and greenhouse gas (GHG) emissions, and the corresponding mechanisms were explored through analysis of microbial characteristics. The results showed that iron scraps and iron - carbon are effective in enhancing the effluent quality of CWs. Iron-carbon exhibited notable efficacy in removing nitrate nitrogen (NO3--N) and chemical oxygen demand (COD), achieving stable removal rates of 98.46% and 84.89%, respectively. Iron scraps had advantages in promoting the removal of ammonia nitrogen (NH4+-N) and total nitrogen (TN), with removal rates of 43.73% and 71.56%, respectively. The emission fluxes of nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2) had temporal variability, always peaking in the early phases of operation. While iron scraps and iron-carbon effectively reduced the average emission flux of N2O and CO2, they simultaneously increased the average emission flux of CH4 (from 0.2349-2.2698 and 1.1956mg/m2/h, respectively). From the perspective of reducing global warming potential (GWP), iron - carbon had superior performance (from 146.2548-86.7447 mg/m2/h).

This study demonstrates a viable approach to the increasing possibility of the salinity reduction of industrial effluent through adsorption. In this work, a novel alginate complex was developed for reducing the salinity of the industrial wastewater to be reinjected and reused again within the industrial process and even in agriculture. The Calcium alginate/clinoptilolite beads (Ca-Alg/Clino beads) were prepared using sodium alginate (2%) solution and calcium chloride (4%) solution as the crosslinking agent with clinoptilolite. Batch experiments were carried out to test the adsorption capacity of the synthetised Ca-Alg/Clino beads. It was found that the salinity reduction process depends strongly on the pH, the adsorbent mass, the interaction time, and the initial salt concentration. The highest reduction efficiency and salinity reduction were achieved at pH (6-7). Batch adsorption experiments indicated that Ca-Alg/Clino beads allow an excellent salinity reduction of up to 96.83% for a dosage adsorbent/water of 2 g/L and a salinity of 6 g/L at a contact time of 20 min. The maximum adsorption capacity (qmax) was 30.1 mg/g. The optimal adsorption pH was 7. The adsorption isotherms data follow well the Langmuir model. The separation factor, RL = 0.74, indicates that the adsorption process is favourable. The kinetics data favour the pseudo-second-order model. The fabricated beads can be reused 5 times without any weight loss.
