Description
Technical field
The present invention relates to technical field of sewage, specially a kind for the treatment of process of aquaculture wastewater.
Background technology
Livestock and poultry breeding industry is a big leading industry of China's agricultural, and Pollution from livestock and poultry then becomes the dirt of China rural area face source
One of the main reason for dye.With the fast development that poultry industry produces, the especially development of large-scale cultivation, a large amount of livestock and poultry row
The generation for letting out object and various wastes causes poultry industry development increasingly prominent with the contradiction of environmental pollution.Due to the excretion of livestock,
The especially use of a large amount of feeds at this stage causes and contains a large amount of polluter in excrement of animals, ultimately causes in sewage
The serious superelevation of biochemical indicator.It is counted according to relevant departments, China just produces in terms of livestock and poultry cultivation more than 20,000,000,000 within 2012
The sewage of ton, this is a quite huge number, is equivalent to the half of China's town domestic sewage and trade effluent total amount.
So develop a kind of raising sewage disposal process become it is current we to solve the problems, such as.
Invention content
The purpose of the present invention is to provide a kind for the treatment of process of aquaculture wastewater, to solve the above technical problems.
To achieve the above object, the present invention provides the following technical solutions：A kind for the treatment of process of aquaculture wastewater, including it is as follows
Step：
（1）, septic tank：It is to precipitate sewage lattice, and the small-sized processing structures of anaerobic digestion are carried out to sludge；Sewage enters
Septic tank passes through the precipitation of 24 ~ 36h, can remove 50% ~ 60% suspended matter.The sludge that precipitates was detested by 3 months or more
Oxygen digests, and so that the organic matter in sludge is resolved into stable inorganic matter, putrefactive primary sludge is converted into stable ripe sludge, changes
The structure for having become sludge reduces the aqueous of sludge；
（2）, regulating reservoir：It ensure that the sewage of various concentration uniformly mixes so that water quantity and quality equalization stable enables subsequent processing
The progress of continuous-stable；
（3）, the ponds UASB：Also referred to as " composite anaerobic pond ", by raising to the space availability ratio of anaerobic pond, the number of anaerobe
Amount configures internal circulation system to improve the treatment effect to organic matter, not only ensures that microorganism can fill with organic matter
Tap is touched, and sludge not easily runs off；The lower part of anaerobic pond lays particular emphasis on hydrolysis acidification effect, by the effect of hydrolysis acidification bacterium,
By macromolecular substances decomposition and inversion at small molecule, biochemical row is improved, while reducing part COD and coloration, is conducive to subsequent oxygen
Change is handled；Middle part and top lay particular emphasis on methanogenesis, have the function of complete anaerobic digestion, by the hydrolysis acidification product of leading portion point
Solution is excluded at substances such as methane, carbon dioxide from system；
（4）, the ponds A2O：Anaerobic system water outlet can remove COD in comparable degree, but cannot reach discharge standard, and aerobic tank is
To the necessary subsequent processing of anaerobic tower water outlet, the microorganism in organic matter and sludge in sewage through coming into full contact with, adsorbing, oxygen
After changing reaction, degradation generates water and carbon dioxide, it is ensured that sewage qualified discharge, Aerobic Process for Treatment are also that present treatment system one is important
Processing unit；Filler is added at O sections, is the effect of back segment possesses catalytic oxidation so that while removing removal organic polluter,
Greatly increase the effect of denitrogenation dephosphorizing；
（5）, vertical sedimentation basin：The sludge from aerobic section is precipitated, precipitates supernatant qualified discharge, pollutant is with sludge form
It precipitates, enters next step Treatment of Sludge；
（6）, sludge drying bed：Sludge drying bed, sludge of the desiccation from sedimentation basin, periodic cleaning mud cake, outer running fertilizer are set
Material, filtrate return to cycle regulating reservoir.
Preferably, the step（2）In regulating reservoir before be equipped with grid, grid use stainless steel steel, grizzly bar gap is
10mm。
Preferably, the step（2）In regulating reservoir in be arranged preaeration stirring system, aeration agitation system be homogenized water
Matter prevents SS from settling.
Compared with prior art, the beneficial effects of the invention are as follows：Present invention process flow is succinct, and it is dirty to can be good at cultivation
Water is effectively handled, and treated that sewage up to standard can be discharged, and will not cause to damage to the ecological environment on periphery
Evil, is conducive to the sustainable health development of ecological environment.
