摘　　要：近年来,符合农村实际、低成本成为农村生活污水治理技术的发展要求,因地制宜、就近就地资源化利用是农村生活污水治理的最佳选择,但由于前期标准缺失、治理体系不完善等原因,导致农村生活污水资源化利用仍是短板。深入分析了我国当前农村生活污水资源化利用率低的原因,指出农村生活污水最佳的资源化途径是回用于农业生产,并在多年研究成果及工程实践的基础上,有针对性地提出农村生活污水治理与农业生产相结合的4种资源化利用模式,即污染物削减与经济作物种植耦合模式、尾水灌溉模式、水质调控型按需排放模式、黑灰水分质资源化利用模式,并对每种模式的特点、适用范围及处理效果、建设投资、运行费用、占地面积等进行了详细分析。In recent years,fitting with the actual situation of rural areas and low cost are becoming the development requirements of rural sewage treatment technology.Adapting measures to local conditions and utilizing local resources are the best choice of rural sewage treatment.However,due to the lack of early standards and imperfect treatment system,resource utilization of rural sewage is still a weak point.The reasons for the low utilization rate of rural sewage were deeply analyzed,and it was pointed out that the best way to recycle rural sewage was to recycle it into agricultural production.Based on years of engineering practice and research results,four resource utilization modes in combination with rural sewage treatment and agricultural production were put forward.These four modes included pollutant reduction and cash crop planting coupling mode,tail water irrigation mode,water quality control type on-demand discharge mode,and black water and grey water graded resource utilization mode.Detailed analysis of the characteristics,application scope,treatment effect,construction investment,operation cost and occupation area of each mode were carried out.
