Mixed breeding system and method combined with domestic sewage treatment

Abstract

The invention relates to the technical field of domestic sewage treatment, and discloses a mixed breeding system and method combined with domestic sewage treatment. The system comprises a dephosphorization tank, an anaerobic tank, an aerobic tank and an irrigation water collection tank, wherein a first water pump is fixedly mounted at the top end of the anaerobic tank, and the water inlet end of the first water pump is communicated with the dephosphorization tank through a first guide pipe; the water outlet end of the first water pump is communicated with the anaerobic tank, a second water pump is fixedly mounted at the top end of the aerobic tank, the water inlet end of the second water pump is communicated with the anaerobic tank through a second guide pipe, the water outlet end of the second water pump is communicated with the aerobic tank, and the irrigation water collecting tank is fixedly mounted through a first supporting frame; a third water pump is arranged between the aerobic tank and the irrigation water collecting tank. The device is reasonable in structure, capable of purifying domestic sewage and utilizing the domestic sewage to irrigate plants, more environmentally friendly, capable of preventing the sewage from being directly discharged to pollute underground water and rivers, good in phosphorus removal effect and high in purification efficiency.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a mixed breeding system and method combined with domestic sewage treatment. Background technique [0002] Farmers' domestic sewage mainly refers to four kinds of sewage, including sanitary water for human feces and urine, washing wastewater, kitchen swill and breeding wastewater. There is no heavy metal pollution in domestic sewage, but it contains a large amount of organic matter, such as cellulose, starch, sugar and fat protein. It also contains chloride, carbonate, bicarbonate, and inorganic substances such as sodium, potassium, calcium, and magnesium, and contains high nitrogen and phosphorus. Under the action of anaerobic bacteria, it is easy to produce odorous substances. Existing farmers produce Domestic sewage is usually directly discharged into ditches and rivers without treatment, which pollutes the river water, makes the river eutrophic, destroys the ...

There is no heavy metal pollution in domestic sewage, but it contains a large amount of organic matter, such as cellulose, starch, sugar and fat protein.

Under the action of anaerobic bacteria, it is easy to produce odorous substances. Existing farmers produce The domestic sewage is usually directly discharged into ditches and rivers without treatment, which pollutes the river water, makes the river eutrophic, destroys the ecological balance of the water body, produces a lot of stench, and affects people's living environment
