Abstract:
Rainwater purification is a key measure in the process of urban non-point source pollution control. In situ rapid purification technology based on physical and physicochemical methods can efficiently remove pollutants from initial rainwater and overflow rainwater, reducing its pollution load into the river. The development of rapid rainwater purification technology at home and abroad has been analyzed by bibliometrics. The results show that hydrocyclone, ultrafiltration, and wetland are widely used rapid rainwater purification technologies. Based on these findings, the performance, advantages, disadvantages, and applicability of rapid rainwater purification technologies such as constructed rapid infiltration, rapid filtration, hydrocyclone, magnetic coagulation, ultrafiltration, and rainwater wetland were summarized, providing a technical reference for the rapid purification and resource utilization of urban rainfall runoff.
