In this paper, the effect of influent load on the performance and microbial community changes of moving bed biofilm reactor(MBBR) in the treatment of highly polluted retorting wastewater was investigated. The MBBR was proposed and demonstrated to be efficient in treating the retorting wastewater, containing COD and NH₄⁺-N of 5000-10000mg/L and 3000-5000mg/L. The removal efficiency of COD and NH₄⁺-N increased steadily in 1-79d, and the effect was the best when the influent load was 0.0242–0.0312kg COD/kg MLSS·d and 0.0173–0.0208kg NH₄⁺-N/kg MLSS·d. The removal efficiency of COD was up to 83.46%, and the removal efficiency of NH₄⁺-N was 82.08%. The long-term operation showed that the biofilm could be rapidly formed after 40 days. Scanning electron microscope observation showed that cocci and short bacilli appeared in the pores of the fillers. With the increase of influent load, the total amount of extracellular polymeric substances increased significantly, in which the content of protein increased sharply in stage III, while the polysaccharide was in a state of continuous and stable growth. High-throughput sequencing analysis showed that the nitrifying functional genus Nitrosomonas was highly enriched in the MBBR system (0 → 17.55%) and played a key role in the high accumulation of NO₃⁻-N. The newly added denitrifying bacteria <i>Brevundimonas</i> (5.85%) and <i>Reyranella</i> (4.57%) enhanced the degradation of COD and maintained the nitrogen cycle in the system. The enrichment of <i>Acinetobacter</i>, <i>Rugosibacter</i>, and <i>unclassified_Syntrophobacteraceae</i> in the system played an important role in the degradation of complex organic compounds such as polycyclic aromatic hydrocarbons and aromatic compounds.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 1","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142694716","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}

A total of 15 samples were collected from 5 sampling spots. Soxhlet extraction technique was applied. Analysis was conducted by gas chromatography/flame ionization detector for aliphatic hydrocarbons and gas chromatography/mass spectrometry for polycyclic aromatic hydrocarbons. Isomeric ratios, such as the carbon preference index, low molecular weight to high molecular weight <i>n</i>-alkanes, etc., were used to infer the sources of <i>n</i>-alkanes. Polycyclic aromatic hydrocarbons diagnostic ratios, including Benzo[b + k]fluoranthene/Benzo[a]pyrene, Phenanthrene/Anthracene, etc., were used to predict PAHs sources into petrogenic and pyrogenic sources. The study also utilized statistical tools like principal component analysis-absolute principal component scores-multiple linear regression for a detailed source appointment. The type of aliphatic hydrocarbon detected in samples ranged from C₁₀H₂₂ to C₃₃H₆₈. Concerning aliphatic hydrocarbon, C₂₁H₄₄ has the highest average presence at 5.224 μg/kg of dry mass in sediment samples whereas, C₁₀H₂₂ shows the lowest mean concentration of 1.953 µg/kg of dry mass. The mean concentrations of the polycyclic aromatic hydrocarbons detected in samples ranged from 0.544 µg/kg for Anthracene to 2.168 µg/kg for Acenaphthene. Primary findings revealed a mix of petrogenic and pyrogenic sources in the coastal sediments, evidenced by the varying aliphatic hydrocarbons and polycyclic aromatic hydrocarbons ratios. Notably, the presence of carcinogenic PAHs highlighted potential health risks. The APCS-MLR analysis identified specific sources influencing hydrocarbon pollution.

In the middle and lower stretch, the levels of electric conductivity (EC), total dissolved solids (TDS), turbidity, dissolved organic matter (DOM), chemical oxygen demand (COD), and nutrients were higher than in the upper stretch. Based on the trophic state index, the upper, middle, and lower stretches were mesotrophic, moderate, and low eutrophic in nature, respectively. In the drinking water category, the water quality index (WQI) ranged from almost good (upper stretch) to inappropriate (middle and lower stretch). Nemerow pollution index (PI_Nemerow) and the comprehensive pollution index (CPI) indicated that most sites were strongly and moderately polluted, respectively. Various point and nonpoint sources of pollution deteriorated the quality of Yamuna water. Spatial cluster analysis divided eleven stations into three groups based on water variables similarity. Discriminate analysis indicated that water temperature, flow, turbidity, pH, dissolved oxygen (DO), magnesium hardness (Mg-H) and COD were the most influencing variables seasonally, while water flow, pH, chloride (Clˉ), DO, Mg-H, and nitrate–N were for spatial variation in Yamuna water quality. Five potential sources were identified using principal component analysis (PCA); anthropogenic, natural, agricultural non-point sources, metrological, and seasonal factors.

A higher K_f value of w-PEMP in Freundlich model suggested that the weathered microplastics surfaces had a higher adsorption affinity for the Cd(II) than p-PEMP. The weathering process also significantly increased desorption capacity of the MPs for Cd(II), and mitigated the influence of pH on the adsorption of Cd(II) onto the MPs.
