Abstract

The invention discloses a breeding wastewater treatment apparatus comprising, in a successively connected manner, a primary filtering tank, a solid liquid separator, an anaerobic reactor, an anoxic tank, an aerobic tank, a precipitation tank, a water culturing tank, and also a biogas tank and a sludge tank, wherein the biogas tank is connected to the anaerobic reactor; the primary filtering tank, the solid liquid separator, the anaerobic reactor and the precipitation tank are all connected to the sludge tank; a grating is arranged in the primary filtering tank; and an aeration pipe is arranged in the water culturing tank. The breeding wastewater treatment apparatus is low in energy consumption and is high in utilization rate on organic substances in the wastewater.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment and relates to a breeding wastewater treatment device. Background technique [0002] With the development of the national economy and the improvement of people's living standards, the demand for animal husbandry products in my country continues to increase, and the animal husbandry industry is also developing in the direction of scale and intensification. The sewage discharged from farms has become an important source of pollution in rural areas. Aquaculture sewage is a kind of high-concentration organic wastewater with a lot of suspended solids, high content of N and P organic matter, and a large number of pathogens. If it is not treated and discharged directly into the surrounding water environment, it will cause eutrophication of the water body and cause surface water quality. seriously deteriorated and pose a certain security threat to the animals and plants in the water body. Du...
