Livestock breeding sewage circulation treatment system and its treatment method

Abstract

The invention discloses a livestock raising sewage cyclic treatment system and method. In order to avoid defects in the prior art, a complete set of sewage cyclic treatment system is designed. The livestock raising sewage cyclic treatment system mainly comprises a fermentation and separation tank, a flocculation tank and a sequencing batch reactor, wherein the fermentation and separation tank separates sewage from excrement in a filtering manner, stacks excrement and performs fermentation treatment on excrement to prepare a fertilizer which is provided for crops; flocculent precipitation is performed on separated sewage in the flocculation tank, and suspended particles in sewage are removed; and at last, bio-purification of sewage is realized through the sequencing batch reactor, so that nitrogen and phosphorus elements and heavy metal elements in sewage are removed. The livestock raising sewage cyclic treatment method realizes recycling of waste and sewage and has the advantages of energy saving and environmental friendliness.

Description

technical field [0001] The invention relates to a sewage treatment method, in particular to a livestock breeding sewage circulation treatment system and a treatment method thereof. Background technique [0002] With the continuous improvement of people's living standards, the demand for cattle, sheep and pork is also increasing. Coupled with the improvement of rural living conditions and the development of agricultural production mechanization, cattle, sheep and pigs have gradually withdrawn from family farming. The current cattle and sheep breeding are mainly large-scale and specialized farms, but affected by many aspects, the production of cattle and sheep in a short period of time cannot meet the domestic market demand. Our meat, beef, mutton and pigs have a low degree of improved breeding, so they show a large number of breeding but low output and poor quality. At the same time, the environmental problems caused by livestock breeding are becoming more and more serious, ...

AI Technical Summary

Problems solved by technology

[0003] 1. There is no effective treatment for aquaculture sewage, and the sewage is discharged randomly, which seriously affects the surrounding water quality;

[0004] 2. Livestock feces cannot be disposed of in time, resulting in the random smell of feces, seriously affecting the surrounding air quality

[0005] 3. Farming sewage and feces cannot be recycled, resulting in waste of resources
