Study on Rural Sewage Ecological Treatment System in China

Abstract

The rapid development of Chinese rural economy has led to an increasingly serious environmental pollution in rural areas, especially the random discharge of sewage to pollute water sources and endanger the health of villagers. This article combines the existing resources and needs in rural areas to study and establish a rural sewage ecological treatment system involving septic tanks, interception wells, improved integrated treatment equipment and waterlogging ponds, and takes Liutian Village in Shaanxi Province as an example. The system is based on the functional and practical principles from the rainwater and sewage collection system to drainage system, treatment system and recovery system. Ecological, economic and effective solutions are adopted in all aspects after comparative analysis. The input cost of the whole treatment system is relatively low, the effect is better and the functions are more. The sewage treated by this system meets the national emission standards. For rural sewage treatment, the system has good economic, social and ecological value and has broad application and promotion prospects.
