农村生活污水处理工艺比较研究

Comparative study on rural domestic sewage treatment technology

农村生活污水的排放量不断增加,加剧了农村环境污染程度。本文在分析了农村生活污水处理现状的基础上,选取了厌氧发酵—接触氧化工艺、厌氧发酵—人工湿地工艺和一体化生物集成工艺处理COD和BOD5三种工艺处理效果,并对处理效果进行了比较,提出了工艺处理的选择建议,为做好农村生活污水处理提供参考。

The discharge of rural domestic sewage is increasing, which has aggravated the degree of environmental pollution in rural areas. Based on the analysis of the status quo of rural domestic sewage treatment, this paper selects the three treatment processes of anaerobic fermentation-contact oxidation process, anaerobic fermentation-artificial wetland process and integrated bio-integration process to treat COD and BOD5. A comparison was made and suggestions for the selection of process treatments were proposed to provide a reference for the treatment of rural domestic sewage.
