生物接触氧化法处理生活污水

Treating living sewage:bio-contact oxidation method

在生物滤池处理生活污水的基础上发展一种利用生物膜处理废水的新方法─—生物接触氧化法。其中心处理构筑物是接触氧化池，池内装有多种填料。从监测结果分析，虽然处理后水质都符合国家排放标准，但BOD5的去除率比较低，只有69％，由于监测是在试运行刚结束进行的，如果一切运行正常，BOD5的去除率可达90％以上。生物接触氧化法是目前比较成熟的生化处理方法，对含有大量有机污染物的生活污水处理效果较好，且处理后的污水还可进行灌溉、建筑、冲洗等重复利用。

A new method of bio-contact oxidation had been developed to utilizebiomembrane to treat sewage on the basis of treating living sewage in biological filteringpool. The central treating building was the contact oxidation pool filled with variousstocks. Analyzing the monitoring and testing results,the author discovered that,thoughthe properties of processed water were in accord with the state's discharging standard,the 69% removing rate of BOD5 was relatively lower. That was caused because the monitoring and testing had been carried out right after finishing trial operation. The removingrate of BOD5 would have been over 90%,if every operation were normal. Biocontact oxidation method is currently a rather ripe one of biochemical treatment,which has considerable better result of treating living sewage with a great amount of organic pollutants.In addition, the processed sewage may be recycled to irrigate, construct building, washand so on.
