Abstract

The invention discloses a kind for the treatment of process of breeding soft-shell turtle sewage.It concretely comprises the following steps:Chinese turtle aquaculture effluent is introduced into coagulation storehouse, obtained supernatant enters filtering cabin and passes through the suspended matter in biochemical filtration cotton removal waste water, the impurity such as bulky grain object, anaerobism storehouse is entered afterwards, pass through facultative COD degradation bacterium therein, denitrifying bacterium, sludge degradation bacterium is degraded the COD in sewage respectively, nitrate nitrogen, nitrite nitrogen and organic sludge, enter back into aerobic storehouse, pass through aerobic COD degradation bacterium therein, ammonia nitrogen degradation bacterium and polyP bacteria are degraded the COD in sewage respectively, ammonia nitrogen and total phosphorus, finally clear water storehouse will be entered after sludge and clear water separation after membrane module is handled, it can qualified discharge, it afterwards can Treated sewage reusing after plus depth processing unit.Present invention process is simple, good sewage processing effect, and a full set of technique, which can be integrated in a set of equipment, to be completed, it can be achieved that automatic operating, easy to maintain and saving space and manpower.

Description

A kind for the treatment of process of breeding soft-shell turtle sewage
Technical field
The present invention relates to the treatment process of breeding soft-shell turtle sewage, are a kind of utilization coagulation, AO and MBR technology and high-efficiency strain Technology, which is combined, carries out Chinese turtle aquaculture effluent processing, belongs to field of environment protection.
Background technology
Soft-shelled turtle is also known as soft-shelled turtle or the soft-shelled turtle, and meat flavour is delicious, and rich in protein, fat, calcium, phosphorus, iron etc., nutritive value is very high, is Treasure is nourished, market demand is very big.Breakthrough particularly recently as soft-shelled turtle greenhouse cultivation technology and be widely popularized and The raising of living standards of the people, breeding soft-shell turtle industry have obtained rapid development, and breeding soft-shell turtle scale in China's has reached generation at present Boundary most.However the feed and soft-shelled turtle excrement of remnants decomposes in hot environment in the breeding process, causes Chinese turtle aquaculture effluent In containing higher nitrogen phosphorus, the unprocessed just directly discharge of a large amount of Chinese turtle aquaculture effluents causes surrounding body eutrophication, seriously Influence ecological environment.
As people are to the pay attention to day by day of environment, environmental problem caused by Chinese turtle aquaculture effluent becomes increasingly conspicuous, exploitation one The efficient breeding soft-shell turtle sewage treatment process of kind is particularly important.
The content of the invention
The present invention is intended to provide a kind for the treatment of process of suitable breeding soft-shell turtle sewage, this method is simple for process, sewage disposal Effect is good, and a full set of technique can be integrated in a set of equipment and complete, it can be achieved that automatic operating, it is easy to maintain and save space and Manpower.
The present invention's is achieved by the following technical programs.
(1)A kind for the treatment of process of breeding soft-shell turtle sewage disposal, includes the following steps:Chinese turtle aquaculture effluent is introduced into coagulation Storehouse, obtained supernatant enter filtering cabin, by biochemical filtration cotton except particulate matter, floating material and suspended matter in decontaminated water etc. Impurity.
(2)The sewage of prefiltration carries out anaerobic reaction in anaerobism storehouse, passes through facultative COD degradation bacterium therein, denitrification Bacterium, sludge degradation bacterium are degraded COD, nitrate nitrogen, nitrite nitrogen and organic sludge in sewage respectively.
(3)Sewage after anaerobic reaction into aerobic storehouse, this sewage pass through by aerobic COD degradation bacterium therein, Ammonia nitrogen degradation bacterium and polyP bacteria are degraded COD, ammonia nitrogen and total phosphorus in sewage respectively, finally after membrane module is handled by sludge and Enter clear water storehouse after clear water separation.
(4)The water outlet of clear water storehouse can be used for Treated sewage reusing by advanced treating.
Step(1)Described in coagulation storehouse used in coagulant be PAC, coagulation generate organic sludge by flowing back into Enter anaerobism storehouse to degrade.
Step(1)Described in biochemical filtration cotton apply the upper carrier for complex microbial community, be attached to biochemical mistake The pollutant and harmful substance in complex microbial community degradation sewage on filter pulp, pre-treatment is carried out to sewage.
Step(2)Described in anaerobic zone, bottom has passage to be connected directly to aerobic aeration area, by Anaerobic Treatment, COD removal rates in sewage can reach 50 ~ 80%.
Step(3)Described in aerobic aeration area, bottom is equipped with aeration plate and carries out uniform aeration, and by sludge reflux extremely Anaerobism storehouse, built-in membrane module are MBR hollow-fibre membranes, and the sewage after degradation is entered by the membrane module that is drawn through of self priming pump Clear water zone.
Step(4)Described in advanced treatment process be activated carbon adsorption or reverse osmosis.
Chinese turtle aquaculture effluent after this process can reach《Urban wastewater treatment firm pollutant emission standard》 (GB18918-2002)The requirement of level-one A standards.
Description of the drawings
Fig. 1 is the processing technological flow figure of the present invention
Specific embodiment
The wastewater treatment that case is area of Tonglu, Zhejiang city breeding soft-shell turtle field is embodied, day output is 100 tons, processing Preceding water quality condition is:250 mg/L of COD, 130 mg/L of ammonia nitrogen, 20 mg/L of total phosphorus.
The waste water of breeding soft-shell turtle field is introduced into coagulation storehouse, and obtained supernatant enters filtering cabin and removed by biochemical filtration cotton The impurity such as suspended matter, bulky grain object in waste water, enter anaerobism storehouse afterwards, pass through facultative COD degradation bacterium therein, denitrification Bacterium, sludge degradation bacterium are degraded COD, nitrate nitrogen nitrite nitrogen and organic sludge in sewage respectively, aerobic storehouse are entered back into, by therein Aerobic COD degradation bacterium, ammonia nitrogen degradation bacterium and polyP bacteria are degraded COD, ammonia nitrogen and total phosphorus in sewage respectively, finally by membrane module After processing will after sludge and clear water separation into clear water storehouse, can qualified discharge, after back segment adds activated carbon adsorption and counter-infiltration system It can Treated sewage reusing.After each phase process, COD removal rates are 80%, and the removal rate of ammonia nitrogen reaches 96%, and the removal rate of total phosphorus reaches To 97.5%, the mg/L of effluent COD concentration after stable operation≤50, the mg/L of ammonia nitrogen≤5, the mg/L of total phosphorus≤0.5 reach《City Town Wastewater Treatment discharge standard》(GB18918-2002)The requirement of level-one A standards.
