Problems solved by technology

[0010] To sum up, in the existing technology, the solid waste in the farm can be effectively treated by biological treatment technology; for the solid-liquid separation of the waste in the farm, the extrusion solid-liquid separation is generally used. machine, the existing problem is that the separation of the extrusion solid-liquid separator is insufficient, and there are a large number of small solid particles in the wastewater after separation, which brings obstacles to the subsequent sterilization treatment; the existing technology of membrane technology and ultrasonic technology can Micro pollutants and bacteria in the liquid can be effectively intercepted or sterilized, but the sundries in the liquid to be treated will affect the treatment effect, so it cannot be directly applied to the treatment of wastewater from dairy farms
[0011] Therefore, dairy farm wastewater contains a large amount of organic matter and other solid impurities and pathogenic bacteria (especially Escherichia coli). Direct irrigation will bring serious environmental pollution, and the treatment of this wastewater is very difficult. It is a major problem in the industry, restricting the development of dairy farming

Abstract

The invention relates to a dairy farm sewage treatment device and a treatment method thereof. The dairy farm sewage treatment device comprises a solid-liquid separation device, an osmotic membrane filtration device, an ultrasonic sterilization actuator and a waste storage tank; waste in the waste storage tank is conveyed to the solid-liquid separation device for solid-liquid separation, and wastewater mixture separated from the solid-liquid separation is conveyed to the osmotic membrane filtration device for filtration, and clear liquid from the osmotic membrane filtration device can be conveyed to the ultrasonic sterilizer actuator for sterilization; and the dairy farm sewage treatment device realizes the efficient separation and degradation of pollutants, and residual colon bacillus inthe clear liquid is treated through an ultra-high power ultrasonic, the sterilization rate reaches 100%, the whole treatment system is convenient to maintain, the treatment cost is lowered, and the operation and management are simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and relates to a dairy farm wastewater comprehensive treatment system, in particular to a dairy farm sewage treatment device and a treatment method thereof. Background technique [0002] In recent years, the degree of intensification, specialization, and scale of dairy farming has been continuously improved, but the metabolism of dairy cows is strong and the feed intake is large. Therefore, with the rapid development of the dairy industry, a large amount of breeding waste is also produced, mainly dairy cow dung, Odous substances such as urine, flushing sewage from cowsheds and milking parlors, among which one cow will produce 100 liters of sewage per day, which contains a large amount of organic matter, nitrogen, phosphorus, suspended solids, heavy metal elements, residual veterinary drugs, protein and fat, etc. The composition, and pathogenic bacteria (especially Escherichia coli) m...
