Summary: Alkaline pre-fermentation was proposed as a method to enhance both methane production and PAM degradation of PAM-flocculated sewage sludge, improving the efficiency of anaerobic digestion. Microbial community analysis showed enrichment of syntrophic bacteria in the alkaline pre-fermenter and elevated levels of acetotrophic methanogen in the anaerobic digester, contributing to the success of this microbial based strategy.

Summary: The effects of potassium ferrate (PF) on acid and methane production in anaerobic digestion were investigated. PF promoted the hydrolysis of organic matter and inhibited methanogenesis due to its high pH. PF directly oxidized proteins and polysaccharides released by hydrolysis to produce VFAs and participate in ammonia transformation. PF induced the enrichment of fermentation-related genes and the reduction of methanogenesis-related genes, which led to the accumulation of VFAs. This study provided a theoretical basis for applying PF to promote VFAs recovery from sludge digestion.

Summary: The presence of PVC microplastics at environmentally relevant levels does not affect methane production but reduces the toxicity of cadmium. When the concentration of PVC microplastics reaches 30 particles/g TS, methane production recovers to 89.7% in the presence of 5 mg Cd/g TS compared to the control. The adsorption of Cd by PVC microplastics is higher than that of sludge-substrate, reducing the bioavailability of Cd during anaerobic digestion.

Summary: This study comprehensively evaluated the impact of free ammonia (FA) pretreatment on the performance of anaerobic primary sludge (PS) digestion using semi-continuous systems. FA pretreatment improved the removal of volatile solids, chemical oxygen demand, and methane production. It also increased the biomass-specific hydrolysis rate of digesters. Model-based analysis revealed that the enhanced performance is due to the increased apparent hydrolysis rate and degradability extent of PS caused by FA pretreatment. Additionally, dewaterability of digested sludge and removals of fecal coliform and E. coli were enhanced by FA pretreatment.

Summary: This study proposes an efficient sludge pretreatment method by combining freezing with calcium hypochlorite for enhancing anaerobic digestion efficiency. Experimental data shows that the optimal combination is freezing at -20 degrees C coupled with 0.075 g/g VSS Ca(ClO)2, resulting in significantly higher biomethane production. Model-based analysis reveals that the combined pretreatment leads to higher potential and rate for methane production. Mechanism analysis demonstrates that the combination effectively destructs extracellular polymeric substances and microbial cells, generating more dissolved organics. Microbial analysis shows that the co-treated reactor enriches more functional microbes responsible for biomethane generation and reduces the number of fecal coliform. This study provides important references for engineers applying the combined freezing and Ca(ClO)2 technology in practical engineering.

Summary: In this study, effective removal of organoarsenic ROX was achieved by the combined process of chlorination + Fe(II), with chlorine degrading ROX effectively at different pH levels. The degradation of ROX was mainly attributed to the reaction between HOCl and deprotonated ROX, while humic acid inhibited this degradation. Furthermore, an enhanced removal of total arsenic was observed after chlorination, with over 97.8% of total arsenic removed.

New anthracite-filtered water contained lower levels of dissolved organic carbon, dissolved organic nitrogen, and ammonia nitrogen compared to aged anthracite-filtered water. Organic carbon was released into the filtered water, with a small percentage being toxic and carcinogenic aromatic carbons.

Summary: Microbes play a dominant role in the degradation of organic contaminants in the environment, yet there is still a lack of understanding regarding the degradation mechanism and the function of different species. This study explores the possible biodegradation of triclosan in a microbial fuel cell, investigating degradation kinetics, microbial community, and possible degradation products. Triclosan at a concentration of 5 mg/L could be degraded within 3 days, with an intermediate degradation product (2,4-dichlorophen) further degraded in the system. A total of 32 dominant bacteria (relative intensity >0.5%) were identified in the biofilm, and 10 possible degradation products were identified. By analyzing the potential bioreactions and degradation pathway based on the identified products, the biodegradation mechanism and function of the bacteria involved in triclosan degradation were clarified. This study provides valuable information for understanding the degradation mechanism of organic pollutants in mixed flora through analysis of the microbiome community and degradation pathway.

Summary: In this study, a novel LED-activated periodate advanced oxidation process (UVA-LED/PI AOP) was developed and investigated for the degradation of naproxen (NPX) and other micropollutants. The UVA-LED/PI AOP showed a broad-spectrum degradation ability, with hydroxyl radical and ozone being the dominant species responsible for NPX degradation. The pH and irradiation wavelength had a negative effect on NPX degradation, explained by the decreased quantum yield of PI. The UVA-LED/PI AOP could be a promising technology for micropollutant treatment in aqueous solutions.

The catalyst showed a higher removal ratio of hard COD and generation speed of hydroxyl radical compared to ozonation alone. In a full-scale application, Fe2O3/Al2O3-SiC catalytic ozonation decreased ozone consumption and operation cost.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
