Abstract

The invention discloses rural domestic sewage treatment. A treatment system comprises an electrochemical tank; a biochemical tank is arranged on one side of the electrochemical tank, a sedimentation tank is arranged on one side of the biochemical tank, and a clean water tank is arranged on one side of the sedimentation tank. Rural domestic sewage is electrolyzed through positive and negative electrodes and matched with the micro-aeration device through the air blower, COD is reduced, oil stains can be decomposed, total phosphorus can be enriched, and clear water obtained after layer-by-layer filtration of the first filter plate, the second filter plate, the third filter plate and the fourth filter plate can be used for landscape planting and farmland planting; and then the sludge left after filtration can be used as an organic fertilizer for farmland planting.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to the treatment of rural domestic sewage. Background technique [0002] At present, most rural areas in my country do not have perfect sewage collection and treatment facilities. A large amount of untreated sewage is directly discharged, which has caused great pollution to the sewage and soil, and will seriously threaten the safety of groundwater and the health of rural residents. [0003] Compared with urban sewage, rural domestic sewage contains a large number of organic pollutants, suspended matter level nitrogen and phosphorus and other nutrients, and has the characteristics of large changes in water quality and quantity, and complex types of sewage. However, the urban sewage treatment technology has the characteristics of large construction investment, large land occupation, long construction period and complicated operation and management, so it is not suitable for ...
