地埋式生活污水处理装置去除效果研究【摘要】为了分散的污水的处理,采用日本净化槽处理工艺,自制了地埋式生活污水处理装置,在荆州市郊某,定期采集生活污水,对其净化效果进行了研究。结果表明:CODBOD、T-N、NH4+-N、T-P、浊度、电导率的去除率%, %, 61%,%,%和11.8%。就各个分室中的不同水质指标去除率来看,厌氧Ⅱ室中BOD5、曝气室中浊度、出水口室中氨氮的去除率最大,分别为53.3%、70.4%和83.2%。虽然进水水质有一定的波动,随着污染负荷的增加,COD、BOD5、T-N、浊度的去除率也随之增加而氨氮的去除率始终保持在95%左右,出水水质好,说明此系统有一定的抗冲击负荷能力达到了预期目标。

Analysis of Removal Efficiency of Buried Domestic Sewage Treatment Equipment
Abstract: In order to carry out the scattered rural sewage treatment, we used the Japanese purification process to make buried sewage treatment plants ourselves, buried in a farmer′s garden in the outskirts of Jingzhou, regularly collected the sewage from each room of the device to study its purification effect. The results showed that: the average removal rate of COD, BOD5, T-N, NH4 +-N, T-P, turbidity, conductivity were 45.4%, 87.8%, 61.1%, 94.5%, 25.2%, 78.9% and 11.8 %. Just from the different water quality index of different room to see the removal rate, anaerobic Ⅱ chamber′ BOD5, aeration chamber′ turbidity, outlet room′s ammonia nitrogen′s removal were the most, 53.3%, 70.4% and 83.2% respectively. Although the incoming water had certain wave, but with the pollution load increased, COD, BOD5, T-N, turbidity′s removal also increased, and the removal rate of ammonia nitrogen was about 95%, the quality of out water was good, indicating that this system had a certain impact
