摘要
提出了三种河水净化方法:①改性膨润土吸附法;②活性炭和红土混合吸附法;③TiO2光催化氧化法。并分别测定了净化前后绍兴环城河水质的浊度、T-SS、CODMn、NH3-N、T-P等指标,结果表明:改性膨润土吸附净化效果较理想,对上述5项指标的去除率分别达到92.81%、96.43%、83.61%、94.01%、97.66%。
This article put forward the three methods for river water purification： ①modified Bentonite absorption; ②the mixture of active carbon and red soil absorption;③TiO2 photoeatalyst oxidation, and measured the water quality as turbidity T-SS,CODMn, ,NH3-N,T-P and so on before and after water purification. The results shown that the modified Bentonite absorption was better, the indexes of above five removal rates can reached 92.81 , 94.01%, 97.66 0% respectirely.
