Modified septic tank for standard reaching treatment of rural toilet dung water and domestic wastewater

Abstract

A modified septic tank for standard reaching treatment of rural toilet dung water and domestic wastewater comprises a septic tank, a packing layer for separating sludge and water, an aeration disc, afan, a time controller for the fan, a sludge pump, a time controller for the sludge pump, a water sterilizing and disinfecting device and an operation control box. The modified septic tank can performpurifying and standard-reaching treatment on the toilet dung water or domestic sewage in scattered peasant households or montanic remote rural households so the treated water quality is translucent and odorless, has no pathogens, and meets first-class standards in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). The modified septic tank has the advantages of simple structure, light weight, low price, convenience in installation, easiness in operation, wide market application prospect, creativity, novelty and good industrial applicability.

Description

technical field [0001] The invention relates to a modified septic tank for the up-to-standard treatment of rural toilet excrement and domestic wastewater, belonging 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. Many township streets, tourist attractions and public toilets in squares are equipped with underground septic tanks. However, due to the influence of the geographical environment, many toilet septic tanks are not connected to the urban sewage treatment pipe network, and are transported away by fecal suction trucks for reprocessing; [0003] At present, the septic tanks of farmers' toilets adopt the well-known doubl...

AI Technical Summary

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. The quality of the discharged water cannot meet the relevant national standards. When the water discharged from the septic tank is exposed to the air, It will gradually become smelly again, breed mosquitoes, and seriously pollute the ecological environment near the septic tank;

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