【摘要】 总结了我国当前农村生活污水的收集处理现状、排水体制、收集处理模式、处理工艺技术等,重点对农村生活污水适用的处理工艺技术优缺点进行了对比阐述。指出活性污泥法为主的工艺技术适用于规模较大、排放标准严格的情况,但是活性污泥工艺运维管理略为复杂;生物膜法更适用于中小规模、排放标准宽松的情况;生态处理法运维成本较低、但占地面积大。农村污水处理工艺技术要根据处理规模、排放标准、成本和运维管理等因素综合评估后选择。低成本、便于维护、资源化是未来工艺技术研发的重点方向。更多还原

【Abstract】 The present situation of rural sewage, drainage system, collection mode, treatment process technology, etc., has been summed in this paper, and we further discussed the suitable process technology for rural wastewater treatment. It is indicated that the activated sludge process is suitable for large scale and strict discharge standards, but the operation and maintenance management of activated sludge process is slightly complicated. Biofilm process is more suitable for medium and small scale with loose discharge standards. The cost of operation and maintenance of ecological treatment process is low, but the land occupation is large. Rural sewage treatment technology should be selected according to the scale, discharge standard, cost,operation and maintenance management. Low cost, easy maintenance and resource utilization are the key directions of rural domestic sewage treatment process technology research issue in the future.更多还原
