Then enters the bottom of the first stirring area 8 from an aerobic water outlet 802 at the upper part of the aerobic area 5, and simultaneously, a coagulant agent is injected into the first medicine adding pipe 18, and the coagulant agent and the sewage enter the first stirring area 8 together, so that the coagulant agent and the sewage are mixed under the action of the first stirring device 9. Then, the sewage enters the bottom of the second stirring area 10 from the first stirring water outlet 1002 at the upper part of the first stirring area 8, and simultaneously, the flocculant agent is injected into the second medicine adding pipe 19, so that the flocculant agent and the sewage are brought into the second stirring area 10, and the flocculant agent and the sewage are mixed under the action of the second stirring device 11, so that a magnetic sludge mixed solution is formed.
The mixed liquid containing magnetic sludge is uniformly distributed on the mud-water separation magnetic flocculation device 13 through the water distribution part 12 to realize mud-water separation, namely the mud-water separation magnetic flocculation device 13 separates the mixed liquid containing magnetic sludge into magnetic sludge and clear water, the clear water flows into a clear water storage area in the mud-water storage tank 17 and is then discharged from the water outlet 15, and the magnetic sludge flows into a magnetic sludge storage area of the mud-water storage tank 17 and is then discharged through the sludge discharge port 16.
This contain magnetism mud from row's mud mouth 16 discharge back, carry magnetic particle separation magnetism flocculation device 7 through row mud pipeline 21 under the effect of impeller pump 20, magnetic particle separation magnetism flocculation device 7 will contain magnetism mud separation for mud and magnetic carrier granule, this magnetic carrier granule falls into and recycles in first stirring district 8, and mud pulls away through the mud car and carries out mud innocent treatment.
The sewage treatment equipment combines A2Compared with the conventional sewage treatment device, the biochemical section of the O treatment process and the magnetic separation technology for separating mud and water have the following advantages:
1. on the basis of ensuring the biochemical treatment effect, the coagulating sedimentation treatment efficiency can be increased, and the equipment size is reduced.
2. The application of the magnetic separation technology can reduce the dosage of the medicament and has low operation cost.
3. The mud-water separation effect is good, and the sewage treatment effect is good.
4. Can adapt to the great change of the content of suspended substances in the sewage.
The above description is only for the specific embodiments of the present invention, and the scope of the present invention can not be limited by the embodiments, so that the replacement of the equivalent components or the equivalent changes and modifications made according to the protection scope of the present invention should still belong to the scope covered by the present patent. In addition, the utility model provides an between technical feature and the technical feature, between technical feature and technical scheme, technical scheme and the technical scheme all can the independent assortment use.
