Problems solved by technology
[0007] (4) There are many solid impurities in the sewage. The sewage produced by the slaughtering and meat processing industry contains a large amount of solid impurities such as animal residues and hair, which increases the technical difficulty of pretreatment
Generally speaking, the sewage produced by the slaughtering and meat processing industry has a high concentration of organic matter and rich nutrients. If it is directly discharged without treatment, it will easily affect the quality of surface water, increase its organic pollution and ammonia nitrogen load, and at the same time it contains Animal remains, etc. will also breed a large number of mosquitoes, bacteria and germs, endangering ecological health and safety

The invention discloses a system for processing breeding and slaughtering sewage and a technology for the system. The system is formed by step-by-step communication of a grid canal, an anaerobic fermentation pool, an oil removal adjusting pool, a combined bi-directional suspended matter separation system, a hydrolysis acidification pool, an oxygen-poor pool, a biological contact oxidation pond and a settling pond. According to the system and the technology thereof, sewage in a livestock farm and a slaughter house can be treated in a comprehensive, energy-saving and environmental-protection manner, sewage can be turned into wealth, the water source can be repeatedly used, natural environment-protection energy can be effectively obtained, and meanwhile, efficiency and rate of reaching the standard in sewage processing can be improved.
Description
technical field [0001] The invention relates to the field of sewage treatment of breeding farms and slaughterhouses, in particular to a system and process for comprehensively and energy-saving treatment of breeding and slaughtering sewage. Background technique [0002] With the continuous growth of my country's per capita meat consumption level, the breeding and slaughtering and meat processing industries have also achieved considerable development. In recent years, the slaughtering and meat processing industry has always been one of the pillar industries that guarantee the supply of daily life in our country. Sewage from this industry is one of the largest sources of industrial pollution in my country. According to the survey, the sewage discharge of slaughtering and meat processing accounts for about 6% of the national industrial sewage discharge, and there is an increasing trend. [0003] The composition of sewage from farms and slaughterhouses is complex, containing a ...
