山东省农村低成本污水处理工艺探讨

Discussion on Low-cost Rural Sewage Treatment Technology in Shandong Province

当前,农村生活污水所造成的污染问题已不容忽视,如何为农村选择适宜的低成本污水处理工艺成为亟需解决的问题。本文在分析山东省农村污水处理工艺影响因素的基础上,结合农村污水处理工艺的选取原则,从国内外污水处理工艺中筛选出20余种适合山东农村的工艺类型,将其归纳为自然处理工艺、生态滤池工艺、新型适用工艺及组合工艺4类。通过对所选工艺的技术特点、适用条件、运维管理及成本等进行分析比较,提出了山东省农村低成本污水处理工艺的选择流程。

At present, the problem of pollution caused by rural domestic sewage cannot be ignored, how to choose suitablelow-cost sewage treatment process for rural areas has become an urgent problem to be solved. Based on the analysis of theinfluencing factors of rural sewage treatment technology in Shandong Province, combined with the principle of selection ofrural sewage treatment technology, more than 20 kinds of sewage treatment processes suitable for Shandong rural areas werescreened from domestic and foreign sewage treatment technologies, and summarized into four categories, including naturaltreatment technology, ecological filter technology, new applicable technology and combination process. Through the analysisand comparison of the technical characteristics, applicable conditions, operation and maintenance management and cost ofthe selected technologies, the selection process of low-cost rural sewage treatment technology in Shandong Province wasdetermined.
