Description
Technical field
The present invention relates to a kind of wastewater treatment equipments, more particularly, to a kind of slaughterhouse wastewater treatment complexes and utilization
The method of described device processing waste water.
Background technique
Waste in slaughtering process is with high concentration organic compounds containing nitrogen, suspended matter and soluble solid object, protein, oil
Based on rouge, a large amount of blood, grease, meat mincing, animal feed, excrement, the mud pig hair, do not digested are contained in generated waste water
The pollutants such as sand, if slaughtering wastewater will cause very big harm to environmental sanitation and human and livestock health without processing direct emission,
The significant wastage of water resource is caused simultaneously.Though pig hair, meat bits and the animal feed not digested belong to can biodegrade
Organic pollutant, but be to need long residence time can be complete after entering biological treatment of waste water system
Biodegrade, this, which does not require nothing more than processing unit, enough volumes, while can increase the disposable investment of engineering；And animal wastes
The organic pollutant for belonging to very easily biological-degradable class, after animal wastes enter biological treatment of waste water system, in the work of biological enzyme
Under, can natural decomposition, so that the content of organics in waste water is become larger, such as COD and ammonia nitrogen, slaughterhouse under normal circumstances
Main organic cod cr≤4000mg/L, An Dan≤200mg/L in the slaughtering wastewater of same day discharge, if do not gone in time
Main organic matter meeting except the animal wastes of easily biological-degradable in waste water, after animal wastes enter waste water treatment system, in waste water
Great change, variation range occur immediately：CODcr≤4000--20000mg/L, An Dan≤200--1200mg/L or so, it is organic
After object concentration becomes larger, the processing difficulty of waste water will increase naturally, increase the volume of wastewater treatment structures, finally still will increase
The disposable investment of engineering.
Conventional slaughterhouse wastewater treatment technique, which is substantially, to be used with bioanalysis as main comprehensive physical and chemical treatment technology
Combined treatment process, the technique of used group technology treatment effect maturation mainly have it is following have it is several：
(1) slaughtering wastewater → preformed precipitate pond → oil separator → conditioning tank → elevator pump → UASB anaerobic reactor → SBR is raw
Object processing unit.Slaughtering wastewater, which flows automatically, enters preformed precipitate pond, and then gravity flow enters oil separator, flows into certainly again after removing amount of grease
Enter wastewater equalization pond, waste water is then sent to by UASB anaerobic reactor by elevator pump and carries out anaerobic biodegradation, slaughtering wastewater
Belong to high concentrated organic wastewater, slaughtering wastewater is handled using anaerobic treatment process under normal circumstances, waste water is in UASB anaerobic reaction
The residence time needed in device is about 72 hours or so, and the supernatant gravity flow after Anaerobic Treatment enters SBR biological treatment
Aerobic biological process is carried out again, then qualified discharge.Slaughtering wastewater uses the above processing method, from inlet water to outlet water, greatly
The residence time of 80 hours is about needed, sewage treatment qualified discharge can be just made.
(2) slaughtering wastewater → oil separator → hydrolysis acidification conditioning tank → elevator pump → UASB anaerobic reactor → intermediate pool
→ elevator pump → filter device.Slaughtering wastewater gravity flow enters oil separator, flows automatically again after removing amount of grease into hydrolysis acidification tune
It saves pond and carries out incomplete anaerobic bio-treated, waste water is then sent to by UASB anaerobic reactor by elevator pump again and carries out anaerobism life
Object degradation, by the processed high concentrated organic wastewater of hydrolysis acidification, the residence time needed in UASB anaerobic reactor is big
About 48 hours or so, the supernatant gravity flow after Anaerobic Treatment entered intermediate pool, then passed through elevator pump again for waste water
It is sent to filter device and is filtered processing, then qualified discharge.Slaughtering wastewater uses the above processing method, from intaking to going out
Water takes around the residence time of 60 hours, can just make sewage treatment qualified discharge.
(3) slaughtering wastewater → oil separator → hydrolysis acidification conditioning tank → elevator pump → bio-contact oxidation aeration tank → bis- are heavy
Pond → sterilization pool.Slaughtering wastewater gravity flow enters oil separator, flows automatically again after removing amount of grease into the progress of hydrolysis acidification conditioning tank
Then waste water is sent to bio-contact oxidation aeration tank by elevator pump again and carries out aerobe drop by incomplete anaerobic bio-treated
Solution, qualified discharge after bio-contact oxidation aeration tank supernatant is precipitated, sterilized.By hydrolysis acidification it is processed butcher it is useless
Water, the waste strength after being directly entered bio-contact oxidation aeration tank is still very high, and organic concentration is CODcr≤2000mg/L
Left and right, and the maximum volumetric loading of bio-contact oxidation aeration tank designs generally in 1.0kgCODcr/m3/d, what is needed is aerobic
Biological treatment device --- the volume of bio-contact oxidation aeration tank is with regard to bigger.Slaughtering wastewater uses the above processing method,
Engineering one-time investment is bigger, and operation energy consumption is higher, very uneconomical.
