According to the invention, toilet liquid dung or domestic sewage of decentralized resident farmer households or remote farmer households in mountainous areas can be purified to reach the standard; treated water is transparent and odorless, has no germs and reaches first-grade standard prescribed in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002); and the device has the advantages of simple structure, light weight, low price, convenience in installation, easiness in operation and convenience in maintenance, and has wide market popularization and application prospects, creativity, novelty and good industrial practicability.

Description

technical field [0001] The invention relates to equipment for purifying toilet excrement or / and domestic wastewater up to standard, and belongs to the field of environmental protection equipment; Background technique [0002] At present, in order to carry out my country's rural toilet revolution, manure water treatment, domestic waste water (including bath waste water, laundry waste water and kitchen waste water) treatment and comprehensive improvement of village appearance, the manure of rural household toilets is discharged into septic tanks.

Problems solved by technology

[0004] With the implementation of my country's rural toilet revolution and rural revitalization plan, it is required to purify and meet the standard treatment of manure and domestic wastewater (including bath wastewater, laundry wastewater and kitchen wastewater) in rural "sources". Although the water discharged from the septic tank kills However, the corpses of the eggs are still in the water, and there are still a large amount of undecomposed organic matter in the water.

[0005] The septic tanks used in rural household toilets or public toilet septic tanks or / and domestic wastewater discharged from rural households that have been disclosed cannot meet the relevant national water quality discharge standards. Through searching and consulting a large number of reports and magazines at home and abroad , books, CDs, patent documents, market advertisements... and other materials, there is no relevant report on "a modified septic tank for toilet excrement or / and domestic wastewater purification and treatment" at home and abroad;
