Integrated livestock breeding waste water treatment method

Abstract

The invention discloses a livestock breeding waste water treatment method, applicable to treatment on various high-concentration organic waste waters. The livestock breeding waste water treatment method comprises the following steps of: 1, after breeding waste waters are uniformly collected, adding polymerized ferric sulphate, flocculating and carrying out primary separation by adopting a solid-liquid separator; 2, carrying out anaerobic decomposition on separated waste water by adopting a UASB (upflow anaerobic sludge blanket) anaerobic process; 3, carrying out a series of high grade materialization reactions when the decomposed waste water enter into an ultrasonic closed circuit generating device; 4, carrying out full oxidation reaction by virtue of an ozone reaction tower after the reacted waste water is subjected to physical filtering; and 5, filtering by virtue of filter materials such as activated carbon and zeolite, thus the waste water can reach up the standard and can be discharged. The livestock breeding waste water treatment method disclosed by the invention can effectively treat livestock breeding waste water, construction fund is greatly saved, less land is occupied, and stable operation cost is low, thus the livestock breeding waste water treatment method disclosed by the invention is especially applicable to industrialized production.

Description

technical field [0001] The invention relates to a method for treating high-concentration organic wastewater, in particular to a method for treating livestock and poultry breeding wastewater. Background technique [0002] Since the 1950s, foreign developed countries have begun to carry out large-scale intensive farming, represented by countries such as the United States, Canada, Japan, and Europe. Domestic large-scale livestock and poultry breeding has developed rapidly since the middle and late 1980s. After more than ten years of development, large-scale breeding has become an independent industry, and the proportion of the output value of the breeding industry in the agricultural output value is increasing. . [0003] The development of the aquaculture industry meets the people's needs for meat, eggs, and milk, and has made great contributions to the development of my country's economy and the improvement of people's living standards. However, the random discharge of manu...
