Intelligent livestock farm sewage ecological cycle purification treatment system and process

Abstract

The invention discloses an intelligent livestock farm sewage ecological cycle purification treatment system and process. A first water level sensor is arranged in a sewage collection tank, the sewage collection tank is connected with an anaerobic fermentation tank through a sewage pump, a second water level sensor is arranged in the anaerobic fermentation tank, the anaerobic fermentation tank is connected with an aerobic aeration tank through a first water pump, a third water level sensor is arranged in the aerobic aeration tank, the aerobic aeration tank is connected with the first-stage constructed wetland through a second water pump, the first-stage constructed wetland is in natural circulation connection with the second-stage subsurface wetland, the second-stage subsurface wetland is in natural circulation connection with the third-stage constructed wetland, a first water quality monitoring sensor is arranged at a water outlet of the third-stage constructed wetland, the third-stage constructed wetland is connected with the fourth-stage subsurface wetland through a third water pump, a second water quality monitoring sensor is arranged at a water outlet of the fourth-stage subsurface wetland, and a water draining pump is arranged at the water outlet of the fourth-stage subsurface wetland. A control device comprises a processor. The system has the characteristics of low cost, high treatment efficiency and good purification effect.

Description

technical field [0001] The invention relates to the technical field of farm sewage purification, in particular to an intelligent pasture sewage ecological cycle purification treatment system and process. Background technique [0002] Due to the huge amount of fecal sewage produced by large-scale farms, it has caused great pressure on the environment. It is an important source of non-point source pollution in rural areas, and it is also a problem that has plagued the farming owners for a long time. Existing farm feces are mostly separated from solids and liquids, followed by anaerobic fermentation. -Aerobic aeration-denitrification and phosphorus removal-ozone disinfection process route, this kind of process hardware investment cost is high, treatment efficiency is low, operation cost is high, and adding drugs in the process is easy to cause secondary pollution, and the sewage treatment effect is difficult to achieve Up to the discharge standard; therefore, it is urgent to pr...

[0002] Due to the huge amount of fecal sewage produced by large-scale farms, it has caused great pressure on the environment. It is an important source of non-point source pollution in rural areas, and it is also a problem that has plagued the farming owners for a long time. Existing farm feces are mostly separated from solids and liquids, followed by anaerobic fermentation. -Aerobic aeration-denitrification and phosphorus removal-ozone disinfection process route, this kind of process hardware investment cost is high, treatment efficiency is low, operation cost is high, and adding drugs in the process is easy to cause secondary pollution, and the sewage treatment effect is difficult to achieve Up to standard emission standards; therefore, there is an urgent need to provide a purification treatment system and process to solve the above problems
