Abstract

The invention provides a treatment and reutilization method for piggery sewage and relates to the technical field of sewage treatment. The method comprises the following steps: (1) carrying out primary sedimentation, and carrying out an anaerobic digestion process; (2) filtering the sewage subjected to primary sedimentation through a wire screen so as to isolate relatively big immobilized granules or weeds; (3) carrying out regulating: adding a mixture of the following substances in parts by weight into the sewage: 10-20 parts of potassium pyrophosphate, 30-50 parts of bentonite, 5-10 parts of slaked lime, 100-200 parts of starch, 3-5 parts of aliphatic amine and 5-8 parts of foamer; (4) carrying out disinfection and deodorization: carrying out mixed bagging on quicklime, dry weeds and caustic soda by using canvas, and throwing bagged canvas bags into a sewage tank in accordance with that 0.5kg to 1kg of the canvas bags is thrown for every 3 square meters of sewage surface; (5) carrying out secondary sedimentation, and carrying out nitration treatment by an aerobic pool; (6) carrying out secondary filtering through a permeable membrane, and then, applying the filtered water to piggery flushing. According to the method, the sewage treatment effect is good, and the sewage is deodorized and disinfected and can be reused, so that the saving of water resources and reducing of wasting are facilitated.

Description

Wastewater from pig farm processes reuse method
Technical field:
The present invention relates to technical field of sewage, particularly relate to wastewater from pig farm and process reuse method.
Background technology:
Wastewater from pig farm mainly includes pig urine, pig manure and pig house washing water.In this kind of sewage organic concentration high, Float is many, ammonia-nitrogen content is high, and stink is big.At present, the sewage treatment process on pig farm mainly by Anaerobic Microbiological Treatment Technology, its advantage is the organic pollution in efficient degradation water, but is difficult to remove waste water In ammonia nitrogen.Denitrogenation generally comprises ammonification, nitrification, denitrification and assimilation Four processes, heterotroph before this Antibacterial is converted into ammoniacal nitrogen organic nitrogen, and ammoniacal nitrogen is nitrite nitrogen nitrogen by autotrophic type oxidation by nitrobacteria, sub- Nitrate nitrogen is nitrate nitrogen by autotrophic type oxidation by nitrobacteria again, last heterotroph denitrifying bacterium by nitrite nitrogen and Nitrate-nitrogen reduction is that gaseous nitrogen is removed from sewage.But the waste water after existing sewage disposal is also direct Discharge, still contains more stink substance, and substantial amounts of antibacterial, it is impossible to again in the waste water after process Secondary utilization, causes the waste of water resource, also the river of discharge or field etc. can be caused certain pollution.
Summary of the invention:
The technical problem to be solved is to provide a kind of good sewage processing effect, deodorization is degerming, Reuse method can be processed by reusable wastewater from pig farm.
For solving above-mentioned technical problem, the present invention uses following technical scheme:
Wastewater from pig farm processes reuse method, it is characterised in that: comprise the following steps,
1) primary sedimentation, by sewage collecting to cesspool, carries out precipitating for the first time, and carries out anaerobism and disappear Metallization processes;
2) filter, the sewage after primary sedimentation is filtered through mesh screen, isolates bigger fixing granule Or weeds;
3) regulation, adds the mixture of following weight portion material in sewage, potassium pyrophosphate 10~20 parts, Bentonite 30~50 parts, Calx 5~10 parts, starch 100~200 parts, fatty amine 3~5 parts and foaming agent 5~8 parts;
4) disinfecting, deodorizing, mixes multi-pack with canvas by quick lime, dry weeds and Caustic soda, the canvas that will install Bag is thrown away in cesspool, and the oilysewage surface of every 3 square metres throws away the canvas bag of 0.5~1 kilogram;Disinfecting, deodorizing Effect retention time is long, has the effect of more preferable disinfecting, deodorizing, additionally adds dry weeds in canvas bag It is effectively to prevent quick lime and Caustic soda from blocking canvas bag while it acts on, thus avoids follow-up sterilization Act on poor.
5) secondary precipitation, and carry out Aerobic Pond nitration treatment;
6) by rinsing for pigsty after permeable membrane secondary filter.
Described foaming agent includes following components, No. two oil 3~5 weight portions, isobutyl group sodium Huangs by weight Medicine 1~3 weight portion, frosting 1~3 weight portion.
Described anaerobic digestion process ferments in anaerobic fermentation pond, adds straw in anaerobic fermentation pond, And abundant and waste water mixed fermentation.
Described Aerobic Pond nitration treatment is interpolation nitrifier in Aerobic Pond.
Described mesh screen, aperture is 250 μm.
The present invention is fermented by anaerobic pond and the effect of Aerobic Pond nitrification, can remove most organic Material, plays the effect processing sewage, and the present invention is through repeatedly precipitating, multiple times of filtration, increases Add the clean level of sewage disposal, during processing, water quality has been regulated, removed in sewage Substantial amounts of gas, heavy metal and the granule etc. swum, these gas major parts all have stink, it is simple to After sewage disposal again with, it is ensured that pig house will not be caused damage by it.
The invention has the beneficial effects as follows: good sewage processing effect of the present invention, deodorization is degerming, can repeat to make With, beneficially saving water resource, reduces waste.
Detailed description of the invention:
The present invention is further illustrated below by embodiment.
Wastewater from pig farm processes reuse method, comprises the following steps,
1) primary sedimentation, by sewage collecting to cesspool, carries out precipitating for the first time, and carries out anaerobism and disappear Metallization processes;
2) filter, the sewage after primary sedimentation is filtered through mesh screen, isolates bigger fixing granule Or weeds;
3) regulation, adds the mixture of following weight portion material in sewage, potassium pyrophosphate 10~20 parts, Bentonite 30~50 parts, Calx 5~10 parts, starch 100~200 parts, fatty amine 3~5 parts and foaming agent 5~8 parts;
4) disinfecting, deodorizing, mixes multi-pack with canvas by quick lime, dry weeds and Caustic soda, the canvas that will install Bag is thrown away in cesspool, and the oilysewage surface of every 3 square metres throws away the canvas bag of 0.5~1 kilogram;
5) secondary precipitation, and carry out Aerobic Pond nitration treatment;
6) by rinsing for pigsty after permeable membrane secondary filter.
