小型污水处理工艺处理生活污水去除效能研究

Study on Removal Efficiency of Domestic Sewage by Small Sewage Treatment Process

目前我国管网配套不完善的单独居住小区和乡镇还缺乏足够的污水处理设施,致使部分污废水未经处理直接排放到自然水体,为有效的解决这些区域水污染问题,改善当地水生态环境,研发适应于这些区域的小型污水处理工艺势在必行。本实验研究针对适应于小区和乡镇的小型污水处理工艺稳定高效处理生活污水,试验研究表明该小型污水工艺对生活污水具有良好的处理效果,COD,NH4+-N,SS和TP的平均去除率分别可达到86.9%,96.7%,97.5%,60.3%。

At present, there is a lack of sufficient sewage treatment facilities in individual residential areas and small towns with out supporting pipe network in China, resulting in some sewage and wastewater directly discharged into the natural water without treatment. In order to effectively solve the water pollution problems in these areas and improve the local water ecological environment, it is imperative to develop the small sewage treatment processes suitable for these areas. In this study, a small sewage treatment process suitable for residential quarters, villages and towns was used to treat domestic sewage stably and efficiently. The experimental results show that the small sewage treatment process has good treatment effect on domestic sewage. The average removal rates of COD, NH4+-N, SS and TP can reach 86.9 %, 96.7 %, 97.5 % and 60.3 % respectively.
