Sewage Treatment Technology of Rural Decentralized Purification Tank

The national agricultural sustainable development planning，clearly pointed out that beautiful countryside and green small town construction were important parts of modern agriculture development.However，the current system of human and livestock pollution in rural areas is backward，pollution sources are scattered，and governance task is arduous.According to rural environmental governance need to solve problem of decentralized wastewater treatment，development situation of decentralized type sewage treatment technology was introduced，dispersion of Johkasou technology was studied，and decentralized type purification tank for sewage treatment engineering design and application were analyzed.The conclusions provided a reference for new rural construction technology selection and policy making.
