生活污水的净化与回用的研究

本文通过静态和动态试验，考察了物化法对污废水有机物的去除效果，认为ＰＡＣ投量为３０ｍｇ／ｌ时，能有效地去除水中有机物的悬浮物，去除率分别为８０％和９０％以上，出水稳定，抗冲击负荷能力强。出水经过过滤，吸附，消毒满足杂用水水质标准的最高值，社会效益和经济效益也非常明显。制水成本０．７７１元／米＾３，是当地自来水成本的５９．９％。

THE ANALYSIS OF PURIFICATION AND REUSE FOR SEWAGE AND WASTE WATER

Using dynamic and static test method, we examined the organic removal rate in sewage and waste water. We observed that when dose 30mg/1 of PAC,more than 80%-90%dissolved and suspended organic materials can be removed, outflow is stable, the ability of againsting alluviation is increased. After filtration,absorption and disinfection,this water can meet the highest standard of common use (no drinkable). This treament method has obvious ecnomic and social benefit. The production cost is 0. 771 yuan per cubic meter, is only 59. 9% of the cost of tap water.
