Description
Technical field
The utility model relates to a kind of integrated A with buffer zone-O biological denitrification reactor.
Background technology
Continuous propelling along with China's process of industrialization; It is serious day by day that water pollutes; Waste disposal plant on the environmental protection field is of a great variety; The existing anaerobic-aerobic Activated Sludge Process (A-O technology) that is used for biological denitrificaion, oxygen-starved area and catalytic oxidation district build formula or Round Sump for dividing, and aerobic reactor part nitrification liquid is back to the oxygen-starved area.Oxygen-starved area, catalytic oxidation district mikrobe do not mix mutually mutually; Flow process is simple, but denitrification zone and organic matter removal, nitrification zone are added with partition, and amphimicrobe gets into aerobic environment by oxygen-free environment at the utmost point in the short period of time; The suffered load impact of bacterial strain is bigger, is unfavorable for the organic matter removal and the nitration reaction of aerobic zone.Special enterprise to seasonal and intermittent blowdown, in case without sewage discharge, aerobic zone bacterial strain will become feeble and die in the equipment out of use phase (, but having increased running cost so again) only if start aerator at any time; When sewage is discharged, must cultivate again because of the aerobic zone bacterial strain, can cause the draining of cultivation phase defective, increase environmental stress, simultaneously, the cultivation phase also can bring the increase of various costs (bacterial classification, logistics, manual work etc.) to enterprise.So traditional process equipment has resistance to overload shock not, particularly can not guarantee the shortcoming of long-term safety stable and high effective operation during seasonal or intermittent blowdown.
The utility model content
The purpose of the utility model is to solve the deficiency of existing A-O biological denitrification reactor; A kind of integrated A-O biological denitrification reactor of novel band buffer zone is provided, overcome traditional A-O biological denitrification reactor complex structure, resistance to overload shock poor performance, effluent quality is not ideal enough, running cost is high and long-time running after shortcoming such as safety and stability performance deficiency.
The purpose of the utility model realizes through following technical scheme: a kind of integrated A-O biological denitrification reactor with buffer zone, and it comprises biochemical zone and settling region, is provided with partition wall between biochemical zone and the settling region; Biochemical zone is divided into oxygen-starved area, buffer zone and catalytic oxidation district; The exit end of oxygen-starved area is connected with the inlet end of buffer zone, and the exit end of buffer zone is connected with the inlet end in catalytic oxidation district, and the exit end in catalytic oxidation district is connected with the settling region; The inlet end of oxygen-starved area is provided with waste water and advances water distributor; Its inside is filled with the stereo biological filler, is filled with mixed fillers in the buffer zone, and catalytic oxidation is filled with combined stuffing in the district; The bottom in catalytic oxidation district is provided with microporous aeration device, and the exit end in catalytic oxidation district is provided with the overflow effluent weir; Be provided with the CD device in the settling region, the CD device is communicated with the overflow effluent weir, and the bottom of settling region is provided with bucket, and the exit end of settling region is provided with the overflow rising pipe.
The described mixed fillers of the utility model is for encrypting mixed fillers.
The beneficial effect of the utility model is: adopt the no dividing plate biochemical zone of band buffer zone, simplified structure of reactor, reduced cost of manufacture, and have characteristics such as effluent quality is good, the resistance to overload shock performance is good and move safety and stability performance is good; When system restarted after short-term is stopped using for some reason, cultivation again again can start fast, has made things convenient for to a great extent to enterprise's use seasonal and intermittent blowdown.
