摘要
介绍了一种两级三段城市污水生物综合处理技术—“2SZ”技术,其主要特点是以复合型高效微生物系列制剂FGB为主体,对城市污水进行予生化处理—生化深处理—物化净化等三段处理,实现了污水资源化深处理。该项技术的一次性建设投资少、耗能低、易操作,运行费用低,所采用的FGB高效微生物制剂使用方便,适应性强,污水处理性能优越,可使污水中的主要污染物COD、BOD、悬浮物及总磷等的去除率达90%以上,氨氮的去除率达85%以上。污泥产出量少,混合预生化池内的污泥存量,每半年左右方需处理一次,是针对具体国情而研发的一项环保类科技实用技术。
This paper introduces a kind of comprehensive processing technique of the living thing of the city waste water.By means of the compound efficient microorganism series FGB,and the three stages of the bio-chemical processing,deep chemical processing and the decontamination of waste water,the recycle of waste water is realized.This technique has many advantages,such as a little investment,low energy consumption,easy operation,and low operation expenses.The efficient microorganism series with high adaptability are used,which can eliminate the main pollutants of COD,BOD,the suspensions,and the total Phosphoru in the waste water,with the rate up to above 90%.The ammonia and the nitrogen are eliminated up to above 85%.The technique with a practical environmental protection aims at our country to develop this project,which produces a little dirty mire.The dirty mire in the bio-chemical pond is handled once every half a year.
