应用EM技术处理生活污水的研究

Sewage Disposal with Effective Microorganisms(EM)

应用活性污泥法投加EM菌对生活污水中化学需氧量、氨氮、总磷的去除效果进行了试验研究和分析 .结果表明 :EM对三类常见污染物均有一定去除效果 .EM接种量 (VEM :VDS)在 1× 10 - 3以下时 ,对CODCr的去除促进作用明显 ,最大增幅为 11.2 6 % ,氨氮去除率最大增幅达 2 2 .2 4 % .

A study was made on the domestic sewage disposal with the activated sludge process by adding effective microorganisms(EM)to remove the chemical oxygen demand(COD),the ammonia nitrogen and the total phosphorus.The results showed that EM is effective in helping remove the three main kinds of pollutants.When the inoculation of EM(V EM V DS ) was lower than 1×10 -3 ,the removal effects of COD Cr were obvious and the reduction rate of it reached as high as 11.26%,with that of ammonia nitrogen reached 22.24%.A derived conclusion is that the aerating time and the quantity of COD Cr inoculation are the key factors for the removal of pollutants.
