Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of embodiments of the present invention, and not all embodiments.
As shown in fig. 1, the pig farm environment treatment system with earthworm cultivation and waste liquid treatment comprises a pig farm 11, an earthworm shed 1, an anaerobic tank 2, a substrate tank 3 and an ecological wetland, wherein the pig farm 11 is communicated with the earthworm shed 1, the pig farm 11 is also communicated with the anaerobic tank 2, and the anaerobic tank 2 is also sequentially communicated with the substrate tank 3 and the ecological wetland.
In the present invention, the excrement of the pigs cultivated in the pig farm 11 is pig manure and pig urine, and other waste liquid is also generated in the pig farm 11 during the pig cultivation process. On the one hand, because pig farm 11 is linked together with earthworm canopy 1, pig manure in the pig farm 11 can be carried in earthworm canopy 1 to be arranged in compost and breed the earthworm in earthworm canopy 1, at the in-process of breeding the earthworm, can produce earthworm cast, earthworm cast is fine fertilizer, and earthworm cast and earthworm price are higher, all have fine market prospect. On the other hand, the waste liquid such as pig urine in the pig farm 11 passes through the anaerobic tank 2 and the matrix tank 3 in sequence, the purpose of preliminary waste liquid treatment is achieved, the waste liquid treated by the preliminary waste liquid flows into the ecological wetland, the ecological wetland can remove pollutants such as nitrogen and phosphorus remained in the waste liquid and discharge the pollutants to the outside in the ecological wetland, and after the waste liquid in the pig farm 11 passes through the anaerobic tank 2, the matrix tank 3 and the ecological wetland in sequence, the quality of the effluent water reaches the national livestock and poultry breeding pollutant standard (GB18956-2001) or the water functional area water quality discharge requirement.
