Description

UCT is used to process slaughtering wastewater system

Technical field

This utility model relates to a kind of slaughterhouse wastewater treatment system, belongs to environment-protection wastewater processing technology field.

Background technology

Slaughtering wastewater butchers processing essentially from livestock breeding, birds, Fish, is one of maximum organic contamination source of China.Slaughter Kill waste water feature be to be typically bronzing, have unpleasant bad smell, wherein contain substantial amounts of blood stains, oils and fats, soft flocks, bone consider to be worth doing, The dirt such as internal organs, feces, solid suspension content is high.Current most of small-scale slaughterhouse is only direct after anaerobic tank processes Discharge, brings serious pollution to water body.

At present the processing method of slaughtering wastewater mainly use 1. UASB-coagulant sedimentation (Guo Yongfu etc. anaerobic UASB- Coagulant sedimentation processes high concentration slaughtering wastewater): through aeration, air supporting after employing mechanical grille removal major part solid pollutant The operations such as pond and SBR tower process slaughtering wastewater, and this technological operation is loaded down with trivial details, and denitrification effect is poor, and processing cost is higher.2. anaerobism Method: anaerobic baffled reactor aerobic basin intermittent aerating pond, although this technique is simple, but processes waste water effect Difference, fluctuation of service.

Although the process to slaughtering wastewater has a lot of method at present, but no matter which kind of method is not ideal, or goes out Water water quality does not reaches emission request, or cost is the highest and cannot apply.Slaughtering wastewater is that one is organic with ammonia nitrogen concentration all The highest waste water, single anaerobism or aerobic process are all inappropriate to slaughtering wastewater, and the water outlet of independent anaerobic technique reaches not To emission request, single aerobic process can not bear the waste water of such high concentration, high load capacity, sludge bulking etc. will necessarily occurs Series of problems, and operating cost is high.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of UCT of employing and processes slaughtering wastewater system to process Tu Kill waste water.Use oils and fats, COD that this system can effectively ensure that in waste water_cr、BOD、NH₃The pollutant removals such as-N, SS, pathogenic bacteria, reach To emission request, and operating cost is cheap, and device structure is simple, it is simple to operation and maintenance.

The technical scheme that this utility model provides is: use UCT to process slaughtering wastewater system, including pretreatment pool, air supporting Pond, hydrolysis acidification pool, UCT pond, sedimentation tank and sterilization pool；Described pretreatment pool includes grid and Microfilter, described grid Connected by water pipe with Microfilter；It is provided with elevator pump between described Microfilter outlet and flotation tank water inlet；Described gas Floating pond outlet is connected with the water inlet of hydrolysis acidification pool by water pipe；Described hydrolysis acidification pool outlet by water pipe with The water inlet in UCT pond connects；Described UCT pond outlet is connected with sedimentation tank water inlet by water pipe；Described sedimentation tank goes out The mouth of a river is connected with sterilization pool.

Further, in described UCT pond also added with superpower addicted to phosphorus bacterium.

Further, it is connected, between described UCT pond and hydrolysis acidification pool, the pipeline having sludge reflux.

Further, described sterilization pool is added with disinfectant ClO₂。

The beneficial effects of the utility model are:

1. flotation tank can effectively remove the colourity in waste water, SS, oils and fats etc., and the Organic substance in waste water is played part Remove, thus ensure the pretreating effect to former water, alleviate the load of subsequent treatment process；

2. macromole and solid organic matters can be resolved into small organic molecule by hydrolytic tank, remove most Organic substance, Bring benefit to subsequent treatment aerobic process, thus be greatly saved the power consumption caused due to oxygen supply；

3. the degraded of solid organic matters can be reduced sludge quantity by hydrolytic tank self, and sewage, mud disposably process, thus can Reduce Treatment of Sludge expense；

4. the COD of part is removed at hydrolytic tank_cr, reducing sewage and enter the volumetric loading of aerobic stage, UCT technique has relatively High, stable clearance, it is ensured that standard water discharge；

5. UCT pond is conducive to Ammonia Nitrification denitrification treatment effect to improve, and denitrogenation is guaranteed.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain This utility model, is not used to limit this utility model.

This utility model is implemented in Xiamen and holds derived food company limited Feng Gang slaughterhouse, the present embodiment slaughterhouse water, day Process wastewater flow rate 500 m³, table 1 is waste water process advancing water water quality:

Referring to the drawings, a kind of UCT of employing processes slaughtering wastewater system, including:

1) pretreatment: slaughtering wastewater removes bulky grain suspended material and bigger solid matter through grid and Microfilter, enters In oil interceptor, removal oils and fats impurity heel row is to regulating reservoir, and filtering residue committee is outer periodically to be processed；

2) flotation tank: in regulating reservoir, the boosted pump of waste water enters flotation tank, adds the wadding such as aluminium polychlorid, polyacrylamide Solidifying agent forms suspension flco, is passed through the decompression release of pressure air-dissolving water simultaneously, produces substantial amounts of micro air bubble and the suspension wadding in water Body is fully contacted, and makes suspension flco in water stick to, on microbubble, climb up on top of the water with bubble, forms scum silica frost, by waste water Oils and fats carry out floating skimming removal by the method for dissolved air floatation and precipitation granule is removed by bottom deslagging, thus effectively Carry out oil removal and slagging-off, make waste water be purified；

3) hydrolysis acidification pool: the waste water crossed through air-flotation process enters hydrolysis acidification pool, under conditions of anaerobic or micro-oxygen, By the hydrolysis of microorganism, larger molecular organics is degraded into small organic molecule, thus removes the COD of part_cr, improve The biodegradability of waste water, reduces the sludge yield of system simultaneously；Nitro state nitrogen in water or nitrous ground state nitrogen are by anti-nitre simultaneously Change effect is converted into nitrogen thus reaches to remove completely the purpose of ammonia nitrogen；

4) UCT pond: through the waste water entrance UCT pond of hydrolysis acidification, add aerobic bacteria under conditions of aerobic, utilize waste water to train Supporting aerobic microbiological, thus form one layer of biomembrane based on aerobic bacteria in cell body, biomembrane is by small organic molecule oxygen Turn to carbon dioxide and water；Ammonia nitrogen in water converts nitrate nitrogen and nitrite nitrogen by Nitrification simultaneously；UCT reaction tank Major part sludge reflux is to hydrolysis acidification pool and UCT reaction tank internal reflux, and excess sludge drains into mud ground；

5) sedimentation tank: through UCT pond processed waste water introduces in sedimentation tank and precipitates, by gravitational settling effect, go Except the SS in waste water, supernatant drains in sterilization pool, supernatant C OD after treatment_cr、BOD、NH₃-N etc. basically reach " Xiamen City's water emission standard " in first discharge standard；

6) sterilization pool: add disinfectant (ClO in sterilization pool₂) supernatant carried out after sterilizing through floss hole row up to standard Put.

After process, draining indices reaches " integrated wastewater discharge standard ".

Table 2 is the effluent quality after waste water processes.
