Description
Technical field
The present invention relates to technical field of sewage more particularly to a kind for the treatment of process of breeding wastewater.
Background technique
China's scale in recent years, intensive livestock and poultry breeding industry flourish, and modernize case type large-scale cultivation skill
Art promotes the livestock and poultry breeding industry in China city to high-quality and efficient development, and the following livestock breeding wastewater discharge amount is also presented
Increase trend year by year, causes the environmental pollutions such as serious soil, water source and air pollution to area.Since China is to pork
Preference, the quantity on pig farm and larger, Wastewater from Pig Farm discharge amount account for the half of livestock and poultry farm wastewater emission amount with
On.Wastewater from Pig Farm high organic content, CODcr are up to 4000~8000mg/L, and BOD5 is up to 1500~6000mg/L, ammonia nitrogen
At concentrations up to 800~1500mg/L, also has the characteristics that antibiotic and pathogen residual, such as handle not in time, not only pollution week
Collarette border also directly affects the health and epidemic prevention on pig farm itself, and the sound development that will restrict entire pig-breeding industry.Pig farm
If waste water treatment process using Anaerobic Microbiological Treatment Technology, its advantage is that can organic pollutant in efficient degradation water, but
It is difficult to remove the ammonia nitrogen in waste water.Denitrogenation generally comprises three ammonification, nitrification, denitrification processes, and heterotrophic bacterium handle had before this
Machine nitrogen is converted into ammoniacal nitrogen, and ammoniacal nitrogen is nitrite nitrogen nitrogen by autotrophic type oxidation by nitrobacteria, and nitrite nitrogen is nitrified by autotrophic type again
Bacterium is oxidized to nitrate nitrogen, and nitrite nitrogen and nitrate-nitrogen reduction are that gaseous nitrogen is removed from sewage by last heterotroph denitrifying bacterium.
However there are following contradictions for biological denitrification process: nitrifier is stringent aerobic bacteria, and nitration reaction needs aerobic environment, and denitrification
Bacterium is facultative anaerobic bacteria, needs to carry out under anaerobic environment.Therefore, livestock and poultry breeding industry ammonia nitrogen in waste water is difficult qualified discharge.
The prior art uses flocculation treatment usually in separating dry space from moist space, and polyacrylamide is added in aquaculture wastewater and gathers
Close the chemical flocs substances such as aluminium chloride.The sewage changed different for concentration, can not accurately control the addition of flocculant
Amount, while the residual volume of flocculant excessive inside liquid can cause fouling membrane to ultrafiltration below and reverse osmosis treatment, furthermore
There are a large amount of flocculant in organic excrement dry matter that separating dry space from moist space obtains, slow down the fermentation process of excrement, while to soil
Improvement hundred evil and none is sharp.And the polypropylene milling amine of high concentration is the agent of nerve intoxicating, is had damage to nervous system.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind for the treatment of process of breeding wastewater, the treatment process first by waste water into
Row collect storage, by spiral agitator by waste water flowing be not easy to precipitate, by waste water uniformly successively introduce inclined wire formula reciprocating sieve,
Multi-stage absorption sedimentation basin, disc type multilayer reciprocating sieve, fine filter tank, bag filter, ultrafiltration apparatus and HCNS film concentration dress
It sets.The dry matter that wherein separating dry space from moist space obtains carries out fermentation process as organic fertilizer raw material, and the clear water that film is concentrated to get can be used as
Recirculated water uses, and another part concentrate is packaged into Liquid Fertilizer after processing.Entire process flow is easy to operate, integration connection
It is dynamic, automatic management may be implemented.And clear water stable effluent quality meets national " animal husbandry pollutant emission standard "
(GB18256-2001) discharge standard；All generation wastes all obtain centralized processing and recycling benefit in technique of the invention
