Description
Technical field
The utility model belongs to the field for the treatment of of water pollution of environmental project, and in particular to a kind of centralized processing of waste water of livestock poultry
System.
Background technology
Poultry industry is the important component of agricultural and rural economy, and the problem of environmental pollution that livestock and poultry breeding industry is brought is very tight
Weight.Livestock breeding wastewater amount that scale livestock farming discharges daily is big, concentrates, and a large amount of pollutant is contained in waste water, as COD,
Ammonia nitrogen, heavy metal, remaining veterinary drug and a large amount of pathogen etc., the waste water of livestock and poultry cultivation, which has to pass through processing, to be discharged.
From the point of view of wastewater treating technology, to realize removal COD, BOD while, then denitrogenation dephosphorizing effect, anaerobic technique
It is indispensable.Multiple means usually can be all combined by current wastewater processing technology, and there are mainly two types of patterns：One is
Anaerobism-Natural treatment mode is suitable for middle-size and small-size scale livestock farming；Another kind is that anaerobic-aerobic utilizes pattern, is suitable for big
Medium-sized livestock and poultry farm or culture zone.The characteristics of Anaerobic Treatment is low cost, is taken up an area less, energy requirement is low, can also generate natural pond
Gas, and processing procedure does not need oxygen, is not limited by oxygen ability is passed, thus there are higher organic loading potentiality, it can make
The partial organic substances that some aerobic microbiologicals cannot degrade are degraded.The common method of anaerobism is thoroughly mixed formula anaerobism and disappears
Change device, Anaerobic Contact reactor, anaerobic baffled reactor, up-flow anaerobic sludge blanket, anaerobic fluidized bed, up-flow solid is anti-
Answer device etc..Natural facture is to purify sewage using the physics chemical action of natural water body, soil and biology.Such method is thrown
Money saves, simple for process, power consumption is few, but purification function is restricted by natural conditions.Naturally the Main Patterns handled have oxidation
The pool, soil treatment method, constructed wetland etc..The basic principle of Aerobic Process for Treatment is decomposed under aerobic condition using microorganism
Organic matter, simultaneously synthesizing own cells.In Aerobic Process for Treatment, it is simple that biodegradable organic matter, which can be finally fully oxidized,
Inorganic matter.This method mainly active sludge, bio-contact oxidation, SBR, A/O and oxidation ditch etc..
In the pattern handled naturally using anaerobism-, waste water of livestock poultry is introduced into setting pot precipitation, subsequently into separation of solid and liquid
Device, isolated waste residue can be comprehensively utilized directly, and waste water enters anaerobic reactor, and the biogas for reacting generation is filled by desulfurization
It is sent into gas-holder stored for future use after setting desulfurization, is reacted and be can be used for irrigating after the waste water left enters oxidation pond processing or arrange outside.
In pattern using anaerobism+aerobic treatment technology, waste water of livestock poultry is introduced into setting pot precipitation, subsequently into solid-liquid point
From device, isolated waste residue can be comprehensively utilized directly, and waste water enters anaerobic reactor, and the biogas for reacting generation passes through desulfurization
It is sent into gas-holder stored for future use after device desulfurization, reacts after the waste water left enters aerobic tank processing and is re-fed into sedimentation basin precipitation,
Waste water outer row after filtering and disinfection later.
CN103288303A discloses a kind of method of the utilization of resources and recycling utilization of livestock breeding wastewater, including
Anaerobic digestion methane production, slagging-off, ammonia nitrogen removal, biological aerated filter biochemistry, disinfection and organic fertilizer manufacture and etc., which is based on
Led to using livestock breeding wastewater as resource based on anaerobic technology, denitrogenation technology, aeration and biological biochemical technology and disinfection technology
Anaerobic fermentation processing is crossed, biogas is produced, produces the waste water after biogas again through being separated by solid-liquid separation, solid slag is used for as production organic fertilizer
The raw material of material produces organic fertilizer, high treating effect, however the invention needs to use nano-catalytic inert electrode, while equipment
More, cost is higher.It is useless that Chinese invention patent CN104326561A discloses a kind of multistage microbial augmentation raising livestock and poultry cultivation
The method of water treatment efficiency, the invention add different types of net in the different processing units of livestock breeding wastewater treatment facility
Water microorganism preparation, enhanced sewage treatment effect finally improve on the whole to improve each processing unit sewage treating efficiency
The treatment effeciency of sewage treatment facility, effluent index further decreases after making processing, is not being changed by the method that the invention provides
In the case of becoming waste water processes and facility, the removal rate of COD and BOD can improve 10-40%, ammonia nitrogen and nitrogen removal rate
20-50% can be improved, sewage treating efficiency improves significantly, however the method that the invention is provided needs the biological agent used
Type is more, while the activity of biological agent is affected by many factors, therefore the popularization and application of this method are restricted.
In conclusion still lacking at present, a kind of governance efficiency is high, waste water of livestock poultry of simple, the easy to spread application of operating procedure
Centralized processing system.
