(1) Economic benefits. In rural areas, the treated domestic sewage can be used as irrigation water or other purposes to save fresh water resources. At the same time, the improvement of environmental conditions in rural areas can reduce the spread of pollution related diseases and reduce the economic losses caused thereby.
(2) Energy efficiency. Rural domestic sewage treatment plants need certain energy consumption. If anaerobic decomposition process is adopted, the biogas generated will be collected for power generation, which can solve some energy problems. Constructed wetlands or land treatment systems generally do not require or consume very little energy. Decentralized sewage treatment facilities need to consume a certain amount of electricity.
(3) Environmental benefits. The most direct effect of rural domestic sewage treatment is the improvement of environmental conditions, especially when the artificial wetland treatment technology is used, the quality of residents' living environment can be improved through the comprehensive treatment of the ecological environment in residential areas.
(4) Social benefits. Rural domestic sewage treatment can not only improve the reuse rate of water resources, alleviate the contradiction between supply and demand of water resources, promote the development of agricultural production, but also improve the ecological environment conditions in rural areas, alleviate the population pressure in cities, promote the harmonious development of society, and play a positive role in the healthy and sustainable development of China's social economy.
