Abstract
The invention discloses a sewage purifying treatment system which comprises a biological fluidized bed, a sedimentation tank I, a biological contact oxidation tank and a sedimentation tank II which are sequentially connected, wherein a fluidized filler is arranged in the biological fluidized bed, and a water inlet of the biological fluidized bed is connected with a sewage discharge port; a first mud bucket is arranged at the bottom of the sedimentation tank I; the first mud bucket is connected with the biological fluidized bed; a clean liquid water outlet is formed at the upper end of the sedimentation tank II, and a second mud bucket is arranged at the bottom of the sedimentation tank II; the clean liquid water outlet is connected with a discharge water tank; the second mud bucket is connected with a sludge tank. The sewage purifying treatment system is simple in structure and easy to realize; the sewage sequentially passes through the biological fluidized bed, the sedimentation tank I, the biological contact oxidation tank and the sedimentation tank II, and the removal rate of organic matters in the sewage is high; moreover, after being discharged to the sedimentation tank I along with the output water, the active sludge in the biological fluidized bed is accumulated in the first mud bucket of the sedimentation tank I, and the active sludge flows back to the front end of the biological fluidized bed by a sludge backflow pump so as to guarantee the concentration of the active sludge and reduce the sewage treatment cost.
Description
Technical field
The present invention relates to a kind of sewage purification processing system.
Background technology
Along with social development, the shortage of water resources, the pollution problem of environment are very serious, and it is particularly important that the processing of sewage, waste water just seems.Existing sewage purification processing system, adopt again the settling tank purifying treatment after adopting biological fluidized bed to be removed organic pollutant, its decontamination effect improving is not ideal enough, and after processing, active sludge in biological fluidized bed often together enters settling tank with water outlet, thereby cause the loss of active sludge, need constantly to add active sludge, cause cost of sewage disposal to increase.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of sewage purification processing system is provided, not ideal enough to the decontamination effect improving of sewage to solve existing sewage purification processing system, the large problem that runs off of the active sludge in biological fluidized bed.
The objective of the invention is to be achieved through the following technical solutions:
A kind of sewage purification processing system, comprise connected successively biological fluidized bed, a heavy pond, biological contact oxidation pond, second pond, be provided with fluidized packing material in described biological fluidized bed, its water-in is connected with Sewage outlet, be provided with the first bucket at the bottom of the pond in described one heavy pond, described the first bucket is connected with biological fluidized bed, the upper end of described second pond is provided with the clear liquid water outlet, and be provided with the second bucket at the bottom of its pond, described clear liquid water outlet is connected with the discharge pond, and described the second bucket is connected with sludge sump.
Further, described the first bucket is connected with biological fluidized bed by pipeline, sludge reflux pump, and described the second bucket is connected with sludge sump by pipeline, pump.
Further, described the first bucket, the second bucket are inverted cone-shaped structure.
Beneficial effect of the present invention is, described sewage purification processing system is simple in structure, be easy to realize, sewage is successively through biological fluidized bed, a heavy pond, biological contact oxidation pond, second pond, and the organic removal rate in sewage is high, and after the active sludge in biological fluidized bed drains into a heavy pond with water outlet, accumulate in first bucket in a heavy pond, and can be by sludge reflux pump by activity sludge reflux to the biological fluidized bed front end, thereby guaranteed the concentration of active sludge, reduced cost of sewage disposal.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of sewage purification processing system of the present invention.
In figure:
1, biological fluidized bed; 2, a heavy pond; 3, biological contact oxidation pond; 4, second pond; 5, the second bucket; 6, the first bucket; 7, fluidized packing material.
Embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
Please refer to shown in Fig. 1, in the present embodiment, a kind of sewage purification processing system, comprise connected successively biological fluidized bed 1, one heavy pond 2, biological contact oxidation pond 3, second pond 4, be provided with fluidized packing material 7 in described biological fluidized bed 1, its water-in is connected with Sewage outlet, be provided with the first bucket 6 at the bottom of the pond in described one heavy pond 2, described the first bucket 6 is inverted cone-shaped structure, it passes through pipeline, sludge reflux pump is connected with biological fluidized bed 1, the upper end of described second pond 4 is provided with the clear liquid water outlet, and be provided with the second bucket 5 at the bottom of its pond, described clear liquid water outlet is connected with the discharge pond, described the second bucket 5 is inverted cone-shaped structure, it passes through pipeline, pump is connected with sludge sump.
During work, fluidized packing material 7 in biological fluidized bed 1 is as biomembranous carrier, the effluent stream that Sewage outlet flows out is crossed biological fluidized bed 1 makes carrier layer be fluidization, thereby strengthen microbial film with the contact area of waste water and fully oxygen supply in the unit time, the microbial film of carrier surface relies on the agitaion of gas, the microorganism that makes to be grown on carrier fully contacts with the organism in waste water, accelerate the metabolism of microorganism, thereby raising clearance, the water outlet of flowing out from biological fluidized bed 1 enters a heavy pond 2, waste water carries out mud-water separation in a heavy pond 2, active sludge accumulates in the first bucket 6, by sludge reflux pump, active sludge quantitatively is back to biological fluidized bed 1 front end, to increase sludge concentration, improve organic removal rate, can make the fluidized packing material 7 run off pass back in biological fluidized bed 1 simultaneously, the concentration that keeps fluidized packing material 7, the clearance of stable organic matter, in addition, due in biological fluidized bed 1 in the state of itching well, and to sewage in a heavy pond 2 in anoxic condition, utilize the nitrification of aerobic autotrophic type nitrifier under the condition of itching well, ammonia nitrogen in waste water is oxidized to nitrite and nitrate, then utilize the denitrification of heterotroph denitrifying bacteria under anoxia condition nitrous acid to be reduced to the process of gaseous nitrogen or oxynitride, reach the effect of denitrogenation dephosphorizing, the water outlet of flowing out from a heavy pond 2 enters biological contact oxidation pond 3, under the effect of aerobic bacteria, utilize metabolism, organism in sewage is become to inorganics and removed, the water flowed out from biological contact oxidation pond 3 enters second pond 4, the aging mud flowed out with waste water precipitates to the second bucket 5 by the gravity mode, then be promoted to sludge sump by pump, the supernatant liquor on second pond 4 tops flows out and enters in the discharge pond from the supernatant liquor water outlet.
Above embodiment has just set forth ultimate principle of the present invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
