Overview of Rural Domestic Sewage Treatment Technology

Collection, as the premise of treatment, is one of the important factors affecting the efficiency of sewage treatment. According to the experience of China, Japan, Europe, the United States, and other countries, decentralized collection, centralized collection, and nanotube collection are three basic modes for collecting rural domestic sewage. Various factors such as local population distribution, sewage quantity, economic development level, environmental characteristics, climatic conditions, topography, local drainage system, and current status of drainage pipeline network should be comprehensively considered before selecting a sewage collection mode. Moreover, the collection system should be planned based on local conditions and the distribution of villages and farmer households. Long-distance drainage pipes should be avoided.
