INSTALLATION FOR deep biochemical WASTEWATER TREATMENT

摘要

The proposed installation relates to biochemical purification vysokontsentrirovannyh sewage containing organic impurities, and can be used for deep purification of industrial sewage alcohol, sugar, yeast, plants of the food and pharmaceutical industry, in the microbial and chemical synthesis.; The installation comprises a receptacle 1-averager, anaerobic purification unit comprising at least one anaerobic bioreactor 3, the anaerobic purification unit comprising at least one aerobic bioreactor 10 with aeration unit. Bioreactors 3 and 10, have the same type of structure which includes a cylindrical body with a coaxial baffle disposed within the hollow head 21, the separating body for communicating between an internal sorption chamber 22 with the fluidized-bed immobilized microflora and a peripheral chamber 23 of the filtration lightening load 24. The upper Thin-layer portion of the housing is mounted a radial and a collection sump 25 the surplus activated sludge 26, the drainage manifold 27 for removal of the clarified water circulation coupled tr boprovodom bioreactor with inlet and venting device, the bottom portion of the housing located drainage manifold 28 for removing filtered water. Each bioreactor is provided with a water distribution chamber 4 is connected to the collector conduit for discharging the filtered water and mounted on the reservoir level for discharging the clarified water circulation and provided with a vertical, not extending to the top of the partition 5 and the venting device. The installation comprises also two heat exchangers 2 and 9, arranged to turn off from the circulation circuit in the pipelines for circulating water from the clarified nodes anaerobic and aerobic purification, disinfection unit, activated sludge process unit and process piping.; The proposed setup allows to ensure a favorable temperature conditions for the activity of microorganisms under any weather conditions change and purify wastewater from baseline BOD 5 mg O ² / dm ^3, more than 3,400 and COD, mg / dm ^3, more than 9,500 to BOD 5 mg O ₂ / dm ³ and not more than 2 COD, mg / dm ^3, 15-30. The total operation time is not more than 6 hours. 7 z.p.f. 1 Fig.
