Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a rural sewage treatment and supporting pipe network system. Background Art

[0002] Rural sewage is mainly a mixture of domestic sewage and wastewater from processing agricultural products. It basically does not contain heavy metals and toxic and harmful substances, but contains a certain amount of nitrogen and phosphorus, and has good biodegradability. At present, there are many differences in the way rural residents discharge domestic sewage. In general, the low density of village and town distribution and the random layout of residents' buildings have led to extremely scattered domestic sewage discharge in rural areas.
