Abstract
The utility model relates to an integrated sewage treatment device adopting a high-load denitrification biological stuffing. The integrated sewage treatment device comprises an anoxic tank, an aerobiotic tank, a vertical flow type sedimentation tank and a sludge tank, wherein structurally, a carbon steel plate with the thickness of 6 mm is adopted, and ribs are additionally arranged; treatment units share walls, so that the structure is compact; technically, the elastic stereoscopic stuffing is arranged in the anoxic tank and the aerobiotic tank, and the height of the stuffing is 1.5 m. The tank capacity ratio of the anoxic tank to the aerobiotic tank is 1:4; in the whole system, except the elastic stuffing, activated sludge is inoculated so that the concentration of suspended activated sludge is 2000 mg/L; a reflux pump arranged inside the aerobiotic tank is contacted, and the reflux ratio is 300%; muddy water inside the sedimentation tank is returned to the anoxic tank and the aerobiotic tank through the air stripping effect of a fan so that the whole system keeps higher concentration of suspended sludge; the muddy water is drained into the sludge tank through the air stripping effect when sludge discharge is needed, and thus the purposes of COD removal, and nitrogen and phosphorus removal are achieved through anoxic and aerobiotic circulation of the reflux sludge; in the aeration mode, aeration pipelines are arranged at the smaller interval of 0.2 m, so that the aeration of the whole system is more uniform, the ascending velocity of bubbles is low, the time of contact between air and water is long, and the mass transfer effect is better.
Description
Technical field
The utility model is a kind of waste disposal plant, specially refers to a kind of high loading denitrogenation biologic packing material integrated sewage treating apparatus.
Background technology
At present, sewage treatment structure mainly adopts Reinforced Concrete Structure.Traditional biological denitrification process mainly comprises A/O, A/A/O, SBR method, oxidation ditch etc.Typical biological denitrificaion method all comprises anoxic pond, Aerobic Pond, and ammonia nitrogen is converted into NO by the biological action of nitrobacteria
3 -, NO
2 -, at the built-in internal reflux pump of Aerobic Pond, set certain reflux ratio constantly by the effluent cycle after aerobic oxidation to anoxic pond, at the mid-sludge reflux pump of second pond, mud in second pond is constantly back to system, with sludge concentration in keeping system, but, the constructional difficulties of Reinforced Concrete Structure, long in time limit, expense is high, the sludge loading of traditional biological denitrogenation is low, the denitrification percent of traditional biological denitrogenation is generally directly proportional to internal reflux ratio, high denitrification percent is just with respect to high internal reflux, thereby cause energy consumption relatively high, control complicated, easily there is the shortcomings such as sludge bulking.
Summary of the invention
In order to overcome sewage treatment structure structure and technologic deficiency, the utility model provides a kind of high loading denitrogenation biologic packing material integrated sewage treating apparatus, this equipment is not only simple in structure, easy construction, and the built-in filler of system improved the sludge loading of technique, strengthen the stability of system.
The utility model solves the technical scheme that its technical problem adopts: a kind of high loading denitrogenation biologic packing material integrated sewage treating apparatus, comprise anoxic pond, Aerobic Pond, vertical sedimentation basin and sludge sump, structurally adopt 6mm thick carbon steel plate to make and reinforcement, and each processing unit is wall altogether, compact construction, in technique, at anoxic pond and the mid-elastic solid filler of Aerobic Pond, the high 1.5m of filler.Anoxic pond is held than being 1:4 with the pond of Aerobic Pond, whole system is except elastic filler, inoculation of activated-sludge makes the activated sludge concentration of suspension at 2000mg/L, the built-in reflux pump of contact Aerobic Pond, reflux ratio is: 300%, muddy water in settling tank returns anoxic pond by the gas stripping of blower fan and Aerobic Pond makes whole system keep higher suspended sludge concentration, while needing spoil disposal, be also to enter sludge sump by gas stripping, backflow sewage is through anoxic, aerobic circulation, remove COD thereby reach, the object of denitrogenation dephosphorizing, on aeration mode, aerated conduit is arranged and is adopted less pitch arrangement, spacing is 0.2m, make whole system aeration more even, bobble rise velocity is slow, air water is long duration of contact, mass transfer effect is better.
The utility model beneficial effect is, compact construction, and small accommodation area, easy construction, expense is cheap, and energy consumption is low.Control by adjusting the nitric efficiency that reflux pump can Controlling System, high sludge concentration has strengthened the stability of system, can be good at playing the effect of removing organic concentration and denitrogenation in sewage.
