Design of a High-Loaded Clarifier and Its Application on the Treatment of Overflow Rainwater

摘要

Overflow rainwater is a serious environmental problem nowadays, which attracted the most researchers' attentions. Accordingly, effective and economic treatment of overflow rainwater is highly required. This study aimed to design a high-loaded clarifier equipment and developed an innovative overflow rainwater treatment. The high-loaded clarifier equipment was consisted of grid, pump, coagulant, reactor, and the most important part of lamella clarifier with serried metal plates. The removal of pollutants in overflow rainwater with the high-loaded clarifier equipment was evaluated. The pollutions removal rate of overflow rainwater was investigated with 65% COD and 90% SS, approximately.
