Sewage treatment system of cultivation farm

Abstract

The invention discloses a sewage treatment system of a cultivation farm, and relates to the technical field of sewage treatment. The sewage treatment system of the cultivation farm comprises a sewage collection tank, a pretreatment tank, a fermentation tank, a filtering tank and a secondary sedimentation tank which are sequentially communicated, wherein the filtering tank is provided with a water inlet communicated with the fermentation tank; a grid is mounted below the water inlet; a water outlet communicated with the secondary sedimentation tank is formed below the grid; a high-pressure pump is mounted below the grid, and connected with the water outlet by a first pipeline; the filtering tank is connected with a manure collection tank; the secondary sedimentation tank and the manure collection tank are both equipped with ultraviolet sterilization devices; the secondary sedimentation tank is connected with a plurality of distributed water pipes by a main water pipe; a metering pump and a first solenoid valve are mounted on the main water pipe; metering valves and second solenoid valves are mounted on all of the distributed water pipes; and the metering pump, the first solenoid valve, the second solenoid valves and the metering valves are connected with a controller. The sewage treatment system of the cultivation farm recycles swill manure of the cultivation farm, and solves the problem of sewage discharge pollution.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system for a farm. Background technique [0002] Under the background of generally encouraging the expansion of breeding production in rural areas, my country's livestock and poultry breeding industry has developed vigorously, showing a trend of industrialization, scale and regionalization in recent years. Due to the large amount of wastewater discharged from large-scale livestock and poultry farms, the high concentration of pollutants, and the long-term lack of attention and management in my country, it has become one of the main sources of pollution in most regions and watersheds in my country, causing serious environmental pollution and a large amount of nitrogen and phosphorus every year. Resource loss and waste. Therefore, how to deal with farm sewage has become a major problem that plagues the development of enterprises. [0003] Farm sewage mai...
