Description
Technical field
The present invention relates to the treatment technology of beer sewage.
Background technology
Along with improving constantly of living standards of the people, China's brewing industry develops rapidly, and beer production increases substantially.Simultaneously, the wastewater flow rate surge of brewing industry discharging, water consumption is big, and contamination level is also big.According to statistical information, one ton of beer of every production, water loss is between the 25-30 ton.A brew-house that produces 200000 tons per year, quantity of wastewater effluent reaches more than 5,000,000 tons.How economical, administer the brewing industry sewage of flood tide like this effectively, preserve the ecological environment, be the important difficult problem that brewing industry faces always.
Present domestic brewing industry sewage water treatment method generally adopts anaerobism (UASB) and aerobic (SBR) combination treatment technology.But, usually in actual use, be difficult to reach GB8978-96 secondary " integrated wastewater discharge standard " requirement, cause unwanted bacteria crossed contamination in factory easily, water uses in can not doing.Have only carry out again RO membrane permeation technology deepen handle and strict sterilization after, could guarantee that the safety input of water re-uses.But the investment of RO membrane permeation technology is big, current consumption is big, and processing cost significantly increases, and beer production producer can't bear the heavy load.And regenerated recycle-water has only about 35%, still has a large amount of wastes.
Summary of the invention
Purpose of the present invention is intended to overcome above-mentioned the deficiencies in the prior art, by a series of test of long duration researchs, propose that a kind of method is simple, less investment, running cost is low and beer sewage is administered after can do in the technique for recycling sewage generated by making beer of water use.
Realize the technical scheme of above-mentioned purpose:
A kind of technique for recycling sewage generated by making beer is characterized in that being made up of following processing step:
1) adding polymerize aluminum chloride in through the beer sewage after the anaerobic and aerobic combination treatment condenses, adsorbs, precipitates, be used for decolouring again, deodorizing, degerming, remove microorganism and algae, based on the amount of beer sewage per ton, the consumption of polymerize aluminum chloride is the 5-10 gram;
2) add chlorine again in beer sewage, be used for sterilization, remove biological oxygen demand (BOD) and chemical oxygen demand, based on the amount of beer sewage per ton, the consumption of chlorine is the 6-8.3 gram;
3) obtain recovery by sand filtration and make water.
A kind of technique for recycling sewage generated by making beer is characterized in that comprising following processing step;
1) add bodied ferric sulfate in beer sewage, carry out coagulation, precipitation, decolouring, deodorizing, degerming, reduction biological oxygen demand (BOD) and chemical oxygen demand, based on the amount of beer sewage per ton, the consumption of bodied ferric sulfate is the 10-20 gram;
2) beer sewage after the step 1) chemical precipitation flows in the aerobe reactor, further removes the organism of difficult degradation and denitrogenates dephosphorization;
3) add polymerize aluminum chloride and condense, adsorb, precipitate, be used for decolouring again, deodorizing, degerming, except that microorganism and algae, based on the amount of beer sewage per ton, the consumption of polymerize aluminum chloride is that 5-10 restrains;
4) add chlorine, be used for sterilization, remove biological oxygen demand (BOD) and chemical oxygen demand, based on the amount of beer sewage per ton, the consumption of chlorine is the 6-8.3 gram;
5) obtain recovery by sand filtration and make water.
Preferably: in above-mentioned adding bodied ferric sulfate, add non-ionic polyacrylamide again, based on the amount of beer sewage per ton, the consumption of polyacrylamide is the 0.5-1 gram.
Adopt technique scheme, beneficial technical effects of the present invention is: 1) through the water after the biological treatment, handle again with polymerize aluminum chloride, mainly utilize the adsorption of effectively building bridge of the hydrolysate of polymerize aluminum chloride between aluminum chloride and aluminium hydroxide, be accompanied by electrochemistry in the hydrolytic process, cohesion, absorption, physical and chemical processes such as precipitation, and its hydrolysate band colloidal electric charge, to producing suspended substance in the water stronger adsorptivity is arranged, so the water after adopting polymerize aluminum chloride to biological treatment is handled again, reach decolouring again, deodorizing, degerming, remove the purpose of microorganism and algae.When 2) handling again, utilize disinfection by chlorine.Because the chlorine low price, consumption is few, sterilization is reliable; be again sophisticated technology; it is again the sterilizing agent that present Running-water Company generally uses; and chlorine can also carry out deodorizing, remove microorganism; chlorine is also high to biological oxygen demand (BOD) and chemical oxygen demand clearance simultaneously, can guarantee to reclaim water conditioning.3) beer sewage carries out coagulating sedimentation by bodied ferric sulfate, because after the bodied ferric sulfate hydrolysis, can produce multiple high price and multinuclear complexing ion, to the colloidal solid that suspends in the water, electrically neutralize, reduce current potential, impel ion that cohesion and precipitation take place, and have dewatering and the strong characteristics of adaptive faculty preferably.Use bodied ferric sulfate have dispensing less, flocculation rate is fast, alumen ustum is big, precipitation is fast, and the function of decolouring preferably in addition, deodorizing, degerming, reduction biological oxygen demand (BOD) and chemical oxygen demand.4) at polyaddition ferric sulfate simultaneously, add non-ionic polyacrylamide again, can reduce the consumption of bodied ferric sulfate, precipitation and dehydrating effect obviously improve simultaneously.5) flow in aerobic (SBR) bio-reactor after the chemical precipitation, further remove the organism of difficult degradation and denitrogenate dephosphorization, can shorten aeration time like this, reduced working cost.6) all regenerations of beer sewage can supply between bottle room washing room, middle recirculated cooling water, van cooler, boiler shop and environmental health water etc.In sum, not only treatment process is simple, investment is few in the present invention.And through brew-house's test run, the treatment effect of beer sewage is good, has saved water resources greatly, and economic benefit is very obvious.
