摘要
在氧化沟内使用培养27天的活性污泥处理生活废水,虽然进水量变化较大,进水中的COD也在81 9mg/L—526 5mg/L之间变化,但出水水质仍比较稳定,COD保持在30mg/L左右,去除率最高可达95%以上。
Activated sludge which is culture of 27 days,treat domestic sewage in oxidation ditch,the quantity of water inflow is vary greatly and the variety of COD is 819mg/l to 5265mg/l,but the water quality of outflow is stable,and the content of COD keep about 30mg/l.The removal rate can reach more than 95%
