Chinese national economy fast development in recent years, requirement to sewage disposal is more and more higher, for solving current sewage disposal, do not catch up with the problem of the national economic development, with pure oxygen aeration activated sludge process, replace the existing air aeration activated sludge process good plan of can yet be regarded as.Pure oxygen aeration abroad tempo is very fast, and range of application is also very extensive.But in Chinese application, be mainly to take petroleum chemical industry as breakthrough point, according to external experience, pure oxygen aeration also has wide practical use aspect municipal sewage treatment.Along with the developing traditional activated sludge process rapidly and will exist aeration limited in one's ability of economy, treatment facility is huge wait not enough.Due to the pressure of the pure oxygen dividing potential drop higher than oxygen in air, pure oxygen aeration can significantly improve the transfer rate of oxygen, adopts pure oxygen aeration can obviously improve the deficiency of traditional activated sludge process.
In activated sludge process, the use of pure oxygen is an old concept.First enters before active sludge based on oxygen work, and the oxygen that high density is given dissolving enters inflow sewage, is called as biogenic sediment system.Follow the research of a worktable, realized the success on biology.Afterwards, use the biological effluent treatment pilot plant of high purity oxygen to have report, although biogenic sediment process has some potential desirable advantages, had some significantly constraint and shortcomings simultaneously.Therefore, a kind of new waste disposal plant of exigence solves above-mentioned technical problem.
Utility model content
In order to solve the problem of above-mentioned existence, the utility model discloses a kind of high efficiency sewage treatment facility, to transform on the basis of existing technology, cost is lower, by improving the transfer rate of oxygen, improves the efficiency of sewage disposal, reduces the quantity discharged of mud.
To achieve these goals, the technical solution of the utility model is as follows, a kind of high efficiency sewage treatment facility, it is characterized in that, described waste disposal plant comprises materialization pond, biochemistry pool, second pond, pure oxygen aeration pond, sterilization pool and sludge dewatering center, the water-in in described materialization pond is inputted former water, the water outlet in materialization pond connects the inlet end of biochemistry pool through pipeline, the exit end of biochemistry pool connects second pond, described second pond connects respectively pure oxygen aeration pond by pipeline, sludge dewatering center and sterilization pool, the outlet of described pure oxygen aeration pond connects respectively materialization pond and biochemistry pool, sludge dewatering center is back to biochemistry pool by supernatant liquor.
As a kind of improvement of the present utility model, described sterilization pool connects sludge dewatering center by pipeline, and the mud discharging after sterilization is arrived to sludge dewatering center.
As a kind of improvement of the present utility model, described sludge dewatering center connects the entrance of biochemistry pool by pipeline, sludge dewatering center is back to biochemistry pool by supernatant liquor.
With respect to prior art, the utility model advantage is as follows, one-piece construction is simple, cost is lower, can under very high aeration tank sludge concentration, keep high dissolved oxygen concentration, can under very high organic loading, move and have very high substrate removal rate, can significantly improve the subsidence rate and the dewatering that improves mud of mud, under identical load, produce less excess sludge, for adopting higher sludge concentration, created condition, simultaneously, bacterial classification in mud is easy coagulation and precipitation also, the operation stability of whole treatment system, impact resistance is all improved.
