Description
Technical field
The present invention relates to sewage treatment area, more particularly to a kind of raising sewage disposal process.
Background technology
Livestock and poultry breeding industry is a big leading industry of China's agricultural, and Pollution from livestock and poultry then turns into the dirt of China rural area face source
One of the main reason for dye.With the development of the fast development, particularly large-scale cultivation of poultry industry production, substantial amounts of livestock and poultry row
The generation of thing and various discarded objects is let out, causes the contradiction of poultry industry development and environmental pollution increasingly to highlight.Due to the excretion of livestock,
The particularly use of a large amount of feeds at this stage, cause and contain substantial amounts of polluter in excrement of animals, ultimately cause in sewage
The serious superelevation of biochemical indicator.Counted according to relevant departments, China is just generated more than 20,000,000,000 in terms of livestock and poultry cultivation within 2012
The sewage of ton, this is a quite huge numeral, equivalent to China's town domestic sewage and the half of trade effluent total amount.
At present, according to relevant policy of government with requiring, most of breeding wastewater field has had methane-generating pit, there is provided a kind of methane-generating pit goes out
Water after-purification handling process, the process problem for solving livestock and poultry cultivation sewage is a very urgent task.
So develop a kind of livestock and poultry cultivation sewage treatment process turn into it is current we to solve the problems, such as.
The content of the invention
It is an object of the invention to provide a kind of hydraulic engineering garbage cleaning device, to solve to carry in above-mentioned background technology
The needs gone out manually ceaselessly salvage rubbish, and labor intensive and rubbish easily largely block sluice, clear up halfway problem.
To achieve the above object, the present invention provides following technical scheme：A kind of raising sewage disposal process, its feature is in institute
The raising sewage disposal process stated comprises the following steps：
After S1, aquaculture wastewater are collected by drainage system, into methane-generating pit；
S2, aquaculture wastewater first flow automatically into regulating reservoir through methane-generating pit, and the regulation of water and water quality is carried out in pond body is adjusted；
S3, the aquaculture wastewater after regulation is delivered to sedimentation basin, remove partial contamination thing and to the processing of follow-up aquaculture wastewater
Unit plays cushioning effect；
S4, aquaculture wastewater enter one-stage hydrolysis acidification pool after sedimentation basin, and one-stage hydrolysis acidification pool is mainly used to strengthen
The biodegradability of sludge, improve sludge activity；
S5, handled into two-stage A/O biochemical synthesis pond by the aquaculture wastewater after hydrolysis acidification；
S6, by the filtered silo of aquaculture wastewater in two-stage A/O biochemical synthesis pond, clear water reserviors, artificial wet land system and clear
It is directly outer behind pond to arrange.
Further, it is added with deamidization in the regulating reservoir in described step S2.
Further, Two-Stage Biochemical comprehensive pool is hydrolyzed by biochemical treatment tank, first stage precipitation tank, two level in described step S5
Acidification pool, one-level A/O ponds, second-level settling pond composition, it is main to remove ammonia nitrogen and total phosphorus pollutant.
Further, there is boring aeration pipe in described two level hydrolysis acidification pool, intermittent aerating, control in aquaculture wastewater
The Anaerobic Treatment of aquaculture wastewater is rested on the hydrolysis acidification stage by dissolved oxygen, the polymer organic matter of difficult degradation is resolved into small
Molecular organic.
Further, described two level hydrolysis acidification pool sets biologic packing material, and a large amount of biomembranes are grown on biologic packing material, cultivation
Sewage and the biofilm contact on biologic packing material, and under the dissolved oxygen conditions of abundance, remove organic pollution in aquaculture wastewater.
Further, the flow direction of sludge is to be constructed from first stage precipitation tank and second-level settling pond by collecting mud bucket into dry cleaning up excrement
Thing, the biogas residue in methane-generating pit are directly entered dry cleaning up excrement structures.
Further, described biochemical treatment tank, is handled using aerobic biochemical process.
Compared with prior art, the beneficial effects of the invention are as follows：Sewage first flows automatically into regulating reservoir through methane-generating pit, in the pond
The content of nitrogen is reduced by adding denitrifier in body, while plays a part of uniform water quality.Sedimentation basin is mainly used to remove portion
Divide pollutant and cushioning effect is played to follow-up sewage treatment unit.One-stage hydrolysis acidification pool be mainly used to strengthen sludge can
Biochemical, improve sludge activity.Handled by the waste water of hydrolysis acidification into two-stage A/O biochemical synthesis pond.Two-Stage Biochemical
Comprehensive pool is made up of biochemical treatment tank, two level hydrolysis acidification pool, two heavy areas and decolouring sterile zones, the main ammonia nitrogen and total Phosphorus of removing
Pollutant.This technique mesophytization processing pond uses aerobic biochemical process, using aerobic microbiological (including aerobic-anaerobic microbe) aerobic
Biological metabolism is carried out under the conditions of gas is existing with degradation of organic substances, microorganism using organic pollution present in water for substrate to enter
Act charitably oxygen metabolism, by a series of biological respinse, release energy, finally settled out with the inorganic matter of low energy position step by step.Two
There is boring aeration pipe in level hydrolysis acidification pool, intermittent aerating, control the dissolved oxygen in waste water to rest on the Anaerobic Treatment of waste water
The polymer organic matter of difficult degradation is resolved into small organic molecule by hydrolysis acidification stage, is advantageous to follow-up Aerobic Process for Treatment.
Hydrolysis acidification pool sets biologic packing material, and a large amount of biomembranes are grown on biologic packing material.In order to prevent biomembrane precipitation from keeping suspending in pond
Biology give up mud.Waste water is degraded to small organic molecule after two level hydrolysis acidification pool, by larger molecular organicses, improves waste water
Biodegradability.Two level A/O biochemical synthesis pond water outlet can be discharged directly, be can also pass through Aquatic-plant Pond and further removed in waste water
Organic matter, ammonia nitrogen and SS.A/O biochemical synthesis pond has the multistage activated sludge sewage processing system of dephosphorization denitrogenation function, uses
Underload activated sludge process, effectively degraded COD by biochemical processing methodCrAnd BOD5, have take up an area compact, process stabilizing,
Low investment, safeguard the features such as simple, operating cost is low.
