集中式沼气能源站与农村粪污资源化利用设计方案研究

针对目前农村粪污在循环资源化利用方面的不足,论述了在农村中建立集中式的粪污(包括人、禽、畜)收集与输送系统、建立村级集中式的沼气发生池以及集中式沼气能源站的重要性、必要性和可操作性,就目前中国农村能源使用的种类和方式及粪污处理的现状进行了汇总性介绍,尤其是针对其存在的问题进行了深入的分析,并结合示例论证,指出了其改进的方向。指出在农村振兴和美丽乡村建设中,应结合自身的特点和优势,大力对可再生能源(尤其是沼气资源)进行开发和利用,这样既可以减轻全国对常规能源需求的压力,也可以同时解决由于对粪污处理不当而造成的农村的环境负担。在农村建立集中式沼气能源站以实现粪污资源化利用,对农村能源的合理利用、农村的厕所革命和美丽乡村的建设将起到重要的积极作用。

Schematic Research on Centralized Biogas Energy Station and Resource Utilization of Excrement in Rural Village

In view of insufficient recycling resource reutilization of rural excrement,importance,necessity and practicality of building-up centralized collecting and transmission system of excrement(including human,poultry and livestock),building-up a centralized biogas generating tank and centralized biogas energy station in a rural village is expounded in this paper.Sorts of energy and means of utilization,status of excrement treatment in rural area nowadays have been introduced collectively.Especially,deep analysis on its existing problems have been carried out and improving direction has been pointed out with an example study.Making full use of characteristics and advantages of rural area,vigorous developing and utilizing renewable energy resources(especially biogas resource)are suggested in rural revitalization and beautiful countryside construction.In this way,not only the nationwide shortage of conventional energy resources is relieved,but also the environmental problems because of the improper treatment of excrement can be solved.Building-up a centralized biogas generating tank and centralized biogas energy station in a rural village has an important positive effect on utilization of excrement,reasonable utilization of energy,toilet revolution,and beautiful countryside construction in rural area.
