Experimental Study On Treatment Paes In Micro-Scale Polluted Source Water By Baf Pretreatment Process

Experimental study has been conducted to evaluate the performance of BAF removing organic matters (PAEs) in micro-scale polluted source water, several factors considered affecting BAF process have been examined which are hydraulic retention time(HTR), the gas-water ratio, different medias of BAF. The test results show that the performance of haydite BAF is better than zeolite BAF. With the gas-water ratio for 1: 1 and HRT for 1.2h, the haydite BAF's removal rate will reach the peck point (average rate 51.88%).
