主 题：Ice pigging Pipe cleaning Drinking water distribution system Bacterial community Sediments
摘 要：Ice pigging is an emerging technique for pipe cleaning in drinking water distribution ***,substantial confusion and controversy exist on the potential impacts of ice pigging on bulk water *** study monitored the microstructural features and composition of sediments and microbial community structures in bulk water in eight multimaterial Chinese *** concentration analysis demonstrated that separate cleaning of pipes with different materials in complex networks could mitigate the risk of losing ice pigs and degrading water *** microstructural and trace element characterization results showed that ice pigs would scarcely disturb the inner surfaces of long-used *** bacterial richness and diversity of bulk water decreased significantly after ice ***,correlations were established between pipe service age,temperature,and chloride and total iron concentrations,and the 15 most abundant taxa in bulk water,which could be used to guide practical ice pigging operations.
