Description
Technical field
Chemical wastewater treatment technical field is the utility model is related to, more particularly to a kind of chemical wastewater treatment system.
Background technology
Chemical production wastewater has the characteristics that colourity is high, toxicity is big, pollutant component is complicated, and its COD value is generally thousands of
In the range of mg/L.A large amount of sludge are generally produced in Aerobic Pond biochemical reaction, sludge precipitates after entering second pond, due to activated sludge
Containing substantial amounts of microorganism and organic matter, it can be used for handling organic wastewater, be optimal selection with biological treatment, so to return
Stream recycles, but existing activated sludge is often back to Aerobic Pond with larger bulk, this larger block sludge with it is outer
Boundary's contact area make it that biochemical reaction efficiency is low less, and it is low to directly result in waste water treatment efficiency.
Therefore, it is necessary to solve the above problems to invent a kind of chemical wastewater treatment system.
Utility model content
The purpose of this utility model is to provide a kind of chemical wastewater treatment system, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the utility model provides following technical scheme：A kind of chemical wastewater treatment system, including adjust
Pond is saved, the regulating reservoir is communicated with coagulative precipitation tank, and the coagulative precipitation tank is communicated with preliminary sedimentation tank, and the preliminary sedimentation tank, which is communicated with, to be detested
Oxygen pond, the anaerobic pond are communicated with Aerobic Pond, and the Aerobic Pond is communicated with second pond, the second pond bottom and Aerobic Pond bottom
Between be communicated with sludge return pipe, be provided with broken mud device on the sludge return pipe, the broken mud device includes multiple
Filter screen and grid.
Preferably, the preliminary sedimentation tank bottom is communicated with sludge collection pond.
Preferably, it is provided with heat exchanger in the preliminary sedimentation tank.
Preferably, multiple mixing pumps are provided with the regulating reservoir.
Technique effect of the present utility model and advantage：By setting broken mud device, filter screen and grid in broken mud device will
Bulk active sludge segmentation in reflux movement is decreased to small bulk, and sludge enters Aerobic Pond and right after sludge return pipe
Enter Organic substance in water and carry out oxidation Decomposition, bulk active sludge become to substantially increase after multiple smaller piece activated sludge with outside
Boundary's contact area, the efficiency of biochemical reaction is effectively improved, so as to improve the efficiency of chemical wastewater treatment.
Brief description of the drawings
Fig. 1 is chemical wastewater treatment system structure diagram of the present utility model.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
The utility model provides a kind of chemical wastewater treatment system as shown in Figure 1, including regulating reservoir 1, the regulation
Pond 1 is communicated with coagulative precipitation tank 2, and the coagulative precipitation tank 2 is communicated with preliminary sedimentation tank 3, and the preliminary sedimentation tank 3 is communicated with anaerobic pond 4, institute
State anaerobic pond 4 and be communicated with Aerobic Pond 5, the Aerobic Pond 5 is communicated with second pond 6, the bottom of second pond 6 and the bottom of Aerobic Pond 5
Between be communicated with sludge return pipe 7, broken mud device 8 is provided with the sludge return pipe 7, the broken mud device 8 includes
Multiple filter screens and grid, by setting broken mud device 8, filter screen and grid in broken mud device 8 live the bulk in reflux movement
Property sludge segmentation be decreased to small bulk, sludge enters Aerobic Pond 5 after sludge return pipe 7 and carried out to entering Organic substance in water
Oxidation Decomposition, bulk active sludge become to substantially increase after multiple smaller piece activated sludge with extraneous contact area, effectively
Ground improves the efficiency of biochemical reaction, so as to improve the efficiency of chemical wastewater treatment.
The bottom of preliminary sedimentation tank 3 is communicated with sludge collection pond 9, and inorganic mud caused by flocculation reaction is discharged, and it is just heavy to reduce
The load in pond 3, heat exchanger is provided with the preliminary sedimentation tank 3, avoid directly in anaerobic pond 4 that heating causes uneven heating even,
Prevent part anaerobic bacteria from receiving infringement, multiple mixing pumps are provided with the regulating reservoir 1, layering can be eliminated by mixing pump, promote
Enter the separation of biogas and digestive juice, while prevent scum layer from crusting.
This practical operation principle：Filter screen and grid in broken mud device 8 split the bulk active sludge in reflux movement
It is decreased to small bulk, sludge enters Aerobic Pond 5 after sludge return pipe 7 and carries out oxidation Decomposition to entering Organic substance in water,
Bulk active sludge become to substantially increase after multiple smaller piece activated sludge with extraneous contact area, improve biochemical reaction
Efficiency.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Progress equivalent substitution, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc.,
It should be included within the scope of protection of the utility model.
