Technology and device for integrated rural sewage treatment by using green energy sources

The invention discloses a technology and a device for integrated rural sewage treatment by using green energy sources. The technology and the device have the advantages that anaerobic particle sludgeis adopted in an anaerobic reaction tank; while the sewage is purified, a large amount of biogas is produced, and the biogas is recycled for desulfurization and dewatering treatment; the biogas is used for generating power to supply power for the whole sewage treatment device, the power supply by external power sources is not required, and the regenerated resources are reasonably used for generating power, so as to reduce the treatment cost; the sewage treatment efficiency is improved. 本发明公开了种使用绿色能源的体化农村污水处理的工艺及其装置，在厌氧反应池中使用厌氧颗粒污泥，在净化污水的同时，产生大量的沼气，之后回收沼气进行脱硫脱水处理，并利用沼气发电，给整个污水处理装置供电，使本设备不需要依赖外部电源供电，并合理利用再生资源发电，降低了处理成本，提高了污水的处理效率。
