Summary: Previous research has mainly focused on the removal of microplastics (MPs) and phthalate esters (PAEs) in wastewater in municipal wastewater treatment plants (MWTP), while ignoring their presence in sludge. This study comprehensively investigated the occurrence and migration behaviors of MPs and PAEs in MWTP. The results showed that the MP removal efficiency reached 98.1%, with about 73.8% of MPs accumulating in the sludge. Additionally, multiple types of MPs and six PAEs were detected in the sludge.

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.
