Abstract
A disclosed slaughter wastewater processing system relates to a processing system for wastewater. The slaughter wastewater processing system consists of a grid, a pre-aeration adjusting tank, an air-floatation room, a hydrolysis-acidification tank, a contact oxidation tank, a secondary settling tank and a disinfection room which are successively connected. According to the characteristics of high organic matter load in slaughter wastewater, the majority of grease, suspensions and the like in the slaughter wastewater can be removed by employing air floatation during pretreatment. Subsequently hydrolysis-acidification treatment is performed for converting macro-molecule organic matters into micro-molecules in wastewater by hydrolysis acidification and for degrading the majority of insoluble organic matters into soluble matters, so that subsequent biochemical treatment load is mitigated. Additionally, the contact oxidation tank is added with efficient active aerobic biological strains, and high-activity return sludge generated by an ordered aerobic reaction tank adsorbs the majority of biodegradable organic pollutants in the wastewater, so that COD and BOD5 in wastewater are effectively removed.
Description
Technical field
The present invention relates to a kind of Waste Water Treatment.
Background technology
Along with the raising of people's living standard, the increase to meat product demand, the ratio of the wastewater discharge of slaughterhouse, meat processing combine in industrial wastewater discharge total amount is also increasing.Slaughterhouse wastewater is from one of the organic contamination source processing ，Shi China maximum of slaughtering of livestock breeding, bird.According to investigations, the quantity discharged of slaughterhouse wastewater accounts for 6% of national discharged volume of industrial waste water, and its pollution also has increasing trend.Because the difficult degraded of organic matter, the intractability of the high density containing are larger, if the not treated direct discharge of slaughterhouse wastewater can produce greatly and pollute water surrounding.Therefore.Control COD, BOD in slaughterhouse wastewater
5,SSDeng contamination index, significant for alleviating water pollution.
Summary of the invention
The present invention aims to provide and a kind ofly can effectively remove COD in water, BOD
5, SS slaughterhouse wastewater treatment system.
Slaughterhouse wastewater treatment system of the present invention, by the grid being connected successively, pre-exposure equalizing tank, between air supporting, hydrolysis acidification pool, contact-oxidation pool, secondary sedimentation basins and disinfection room.
The feature that the present invention is high according to slaughterhouse wastewater organic loading, pre-treatment adopts air supporting can remove wherein most grease, suspended substance etc.Following adopted acidication is processed can become small molecules by the larger molecular organics acidication in water, by the insoluble organic matter degradation of major part, is dissolved matter, thereby alleviates follow-up biochemical treatment load.In addition in contact-oxidation pool, add high-efficiency activated aerobe bacterial classification and high reactivity returned sluge that in order aerobic reaction pond produces, most in absorption sewage can biochemical organic pollutant. can effectively remove COD in water, BOD
5.Whole slaughterhouse wastewater treatment system is stable, has created good economy, society and environmental benefit.As can be seen here, this slaughterhouse wastewater treatment system is processed in practice feasible, reliable at slaughterhouse wastewater.

Slaughterhouse wastewater treatment system of the present invention, by the grid being connected successively, pre-exposure equalizing tank, between air supporting, hydrolysis acidification pool, contact-oxidation pool, secondary sedimentation basins and disinfection room.
Waste water enters pre-exposure equalizing tank after grid is removed oarse-grained suspended substance and staple fibre, regulating pondage, homogenizing water quality.In equalizing tank, a small amount of aeration fully mixes waste water simultaneously, reduces sludgd deposition.By pump, promote and enter efficient air-floating apparatus again, remove tiny suspended particle, oil slick and non-solubility organism etc. in water.Waste water flows into after hydrolytic tank, under anerobe effect, the larger molecular organics acidication in water is become to small organic molecule.By the insoluble organic matter degradation of major part, be dissolved matter, improve the biodegradability of sewage.Solid organic matters degraded is reduced to sludge quantity simultaneously, reach the effect of denitrogenation dephosphorizing.Enter after contact-oxidation pool, by adding active sludge and active aerobe bacterial classification.Biological inoculum is contacted domestication, built-in orderly aerobic system in this device.The current of utilization system are controlled with refresh function and are realized biological degradation.Replace traditional catalytic oxidation, formed special efficacy biochemical sewage treatment system, efficiently removed COD, BOD in water
5.In biological contact oxidation pond water outlet, contain the inorganic suspended particles of bringing in the microbial film that comes off and waste water, must carry out mud-water separation through secondary sedimentation basins; The clear water that secondary sedimentation basins is discharged, except coliform exceeds standard, has all reached emission standard, so clear water must be through disinfecting. and this engineering adopts dioxide peroxide to carry out disinfection to water outlet, and after sterilization, water outlet reaches emission request completely, through sewage draining exit, discharges.
In pre-exposure equalizing tank, by pneumatic blending, guarantee that the water quality and quantity of subsequent biological treatment facility water inlet is balanced, degraded some organic pollutants, to alleviate the processing load of follow-up aerobic section.Equalizing tank adopts skeleton construction, and useful volume is 300 m
3, hydraulic detention time is 8 h, establishes 2 sewage pumps in pond, 1 use 1 is standby.Flow 30 m
3/ h, lift 10 m, power 22 kW.
Air supporting has high-efficiency dissolued-air air-floating apparatus l cover in hearing.Be used for removing sewage suspended substance, grease and the pollutents such as COD are had to certain removal effect.The designing treatment water yield is 150 m
3/ h.Supporting chemicals dosing plant.Adopt brick mix structure.Be of a size of 4mx4mx3 m.
Hydrolysis acidification pool internal anaerobic biological domestication device, and in addition adaptability domestication of the anaerobic species dropping into, anaerobic bacterium under anaerobic becomes the larger molecular organics acidication in water into small molecules, by the insoluble organic matter degradation of major part, be dissolved matter, improve the biodegradability of sewage.For aerobic treatment creates conditions.This pond is skeleton construction, and useful volume is 260 m
3, HRT=7.2 h.
The aerobic bacterial classification absorption of the built-in activity of contact-oxidation pool leading portion domestication device.Stage casing is floating filler biological contact oxidation pond, and back segment is fixing filler biological contact-oxidation pool.Operation adds active sludge and high-efficiency activated aerobe bacterial classification early stage, and biological inoculum is tamed in domestication device.Make high loading microorganism and underload microorganism enter in order stage casing and back segment by Controlling System.The high reactivity returned sluge absorption that in order aerobic reaction pond produces and remove most in sewage can biochemical organic pollutant.The current of aerobic system utilization system and microbiological manipulation and refresh function have formed special efficacy biochemical sewage treatment system in order, can effectively remove COD in water, BOD
5.Contact-oxidation pool is skeleton construction, and useful volume is 280 m
3, HRr=8.6 h.
Secondary sedimentation basins is the water outlet of solid-liquid separation contact-oxidation pool, removes most of SS, part COD in water, and waste water is thoroughly purified, and guarantees discharged wastewater met the national standard, and spy arranges 1 second pond, useful volume 120 m
