Abstract
The invention relates to sewage treatment and discloses a sewage treatment system in a powder coating factory. Sludge floats to be further treated by adopting a suspension method. The sewage treatment system comprises a first reservoir, a second reservoir, a third reservoir, a plate-frame pressure filter and a pneumatic diaphragm pump which are sequentially connected with one another, wherein sewage in the third reservoir is filtered by the plate-frame pressure filter, and filtered clear water is discharged into the second reservoir; the pneumatic diaphragm pump is connected in front of the plate-frame pressure filter and is used for pumping the sewage into the plate-frame pressure filter; multiple fine bubble aerators are arranged at the bottom of the third reservoir; compressed air is introduced into the bottom of the third reservoir; and the sludge is suspended by virtue of the fine bubble aerators. The sewage treatment system disclosed by the invention is combined with a water spray secondary dust removal system, continuous operation can be realized, cyclic utilization of water is realized, water resources and manual labor are greatly saved, the system is simple and environmentally-friendly, and the cost is saved.
Description
Technical field
The present invention relates to sewage disposal, the process of the sewage especially produced in powdery paints production technology.
Background technology
In the production process of powdery paints, process containing the method for dust sewage is usually, after sedimentation certain hour, is dug out by the mud manpower be deposited in pond by sewage in pond.Low and the weak effect of this sewage water treatment method disposal ability, waste water resource and manpower, thoroughly can not remove powder, and tail gas compliance rate is low, and not environmentally, cost is high, cannot adapt to the Production requirement of modernization main equipment.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of can the powdery paints plant effuent treatment system of continued operation, supporting modern paint production plant, overcomes the problem of the not high and weak effect of sewage treatment capacity.
For solving the problems of the technologies described above, present invention employs suspension method and mud is floated the technical scheme be further processed: powdery paints plant effuent treatment system, comprise the first cistern, the second cistern, the 3rd cistern, plate and frame filter press and the pneumatic diaphragm pump that are connected successively, wherein depositing in clear water, the 3rd cistern to store in the first cistern and the second cistern has sewage.
Described plate and frame filter press is provided with sewage inlet, clear water output and cake outlet, and its effect is the sewage in filtration the 3rd cistern, and the clear water after filtering to the second retention reservoir discharge, the mud after filtration is made dry mud cake simultaneously.
Before described pneumatic diaphragm pump is connected to plate and frame filter press, for sewage is pumped into plate and frame filter press; Native system also comprises air compressor, simultaneously to the 3rd columns base and pneumatic diaphragm pump conveying compressed air.
Described 3rd columns base is provided with multiple micro-hole aerator, therefrom sprays compressed air and makes sludge suspension, and preferably, micro-hole aerator is circular, and diameter is 7-10cm.
Described first columns base is provided with two submersible sewage pumps.The second cistern limit adjacent with the 3rd cistern, higher than the second cistern limit adjacent with the first cistern, enters the first cistern to make clear water from the second cistern overflow.
Sewage handled by the present invention comprises the sewage after from tails dedusting, cleaning meter Sai Ke sewage and cleans and crush machine conduit wastewater.
The present invention has following beneficial effect:
1. save artificial;
2. can continued operation;
3. the clear water after process can be recycled;
4. the energy is saved, simple environmental protection.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, whole sewage disposal system can process the sewage after from tail gas final dusting, clean meter Sai Ke sewage and clean and crush machine conduit wastewater, comprise the first cistern 1 be connected successively, second cistern 2, 3rd cistern 3, wherein deposit clear water in the first cistern 1 and the second cistern 2, store in 3rd cistern 3 and have sewage, second cistern 2 limit adjacent with the 3rd retaining 3 pond is higher than the limit of other cisterns, make like this clear water in the second cistern 2 store full after can overflow in the first cistern 1, submersible sewage pump 4 is had bottom first cistern 1, clear water is transported to Water spray secondary dedusting system to be used for purifying the tail gas containing powder particle, also clear water can be pumped and do other uses.There is pending sewage in 3rd cistern 3, bottom it, is provided with several micro-hole aerators 5, after passing into these micro-hole aerators 5 from the compressed air of air compressor, make the sludge suspension in pond.Compressed air is transported to pneumatic diaphragm pump 7 simultaneously, and the mud that suspension is got up then is pumped to the sewage inlet 61 of plate and frame filter press 6 by pneumatic diaphragm pump 7.Plate and frame filter press 6 is by the filtering slurry in sewage, and clear water flows into the second cistern 2 from clear water output 62, and the mud filtered out is pressed into dry mud cake and discharges from cake outlet 63.
Sewage disposal system of the present invention and Water spray secondary dedusting system combinationally use, can continued operation, realize recycling of water, greatly save water resource.Can be disposed of sewage current every day of the present invention 2000kg, meets plant produced needs.
Be more than better embodiment of the present invention, but protection scope of the present invention is not limited thereto.Any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the conversion expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore the protection domain that protection scope of the present invention should limit with claim is as the criterion.
