Study of Typical Treatment Technology of Domestic Sewage in Mountainous Rural Areas
Rural domestic sewage has gradually become one of the important factors of water pollution in China,and it is al-so the main bottleneck for the overall improvement of rural environmental quality.Mountainous areas have the characteristics of large terrain undulations,poor water storage capacity,and scattered settlements,which makes domestic sewage treatment difficult.In order to explore the typical domestic sewage treatment technology applicable to mountainous rural areas,taking Shiyan City as an example,by analyzing the status quo and treatment mode of rural domestic sewage treatment in Shiyan City,three combined processes of pretreatment+anaerobic pond+constructed wetland,pretreatment+biological filter+(con-structed wetland)and anaerobic biological treatment+plunge aeration aerobic biochemistry suitable for mountain rural domes-tic sewage treatment were screened out,in order to promote the treatment of rural domestic sewage in mountainous areas and win the battle against pollution.Provide reference for building ecological livable villages.
