Abstract
The invention designs a technology for treating scouring sewage and sludge. According to the technology, the sewage is treated in an air-floating pond, an anaerobic pond, an aerobic pond and a settling pond, wherein compound iron and organic cation polymeric flocculant are added when the sewage is treated in the air-floating pond; after the treatment is finished, alkali liquor is added into the sewage till pH value reaches 7.5; and then the sewage is treated in the anaerobic pond; and meanwhile, a DO (Dissolved Oxygen) value in the aerobic pond is controlled at 3.5. The technology has the characteristics that the physical action of air floating and the chemical action of the compound iron and the organic cation polymeric flocculant are utilized to recover wool grease, treat the flocculation sludge and reduce the COD (Chemical Oxygen Demand) value of the sewage at the same time.
Description
Technical field
The present invention relates to a kind of sewer sludge treatment technique, the wool washing sewage sludge treatment technique that uses in the particularly a kind of scouring of wool factory.
Background technology
It is the main point of scouring of wool processing profit that scouring of wool factory yolk reclaims; And yolk generally is rich in the resulting sewage sludge of scouring of wool, and existing processes is that grease is obtained with floating the removing of acid out method, and acid out is to need the ph value of a large amount of ferrous sulfate reduction of use sewage in the hope of separating out more yolk; But because sour environment uses during to the sewage aftertreatment mikrobe unfavorable; Need to add the ph value that a large amount of alkali lye comes neutralization solution so after acid out is accomplished, have, the compounds such as ironic hydroxide that ferrous sulfate and liquid caustic soda produce need once more floating removing again; Increase processing cost, make that the cost of handling is high.
Summary of the invention
The objective of the invention is provides a kind of process simplification for the deficiency that solves above-mentioned technology, and use cost is low, and sludge quantity produces few wool washing sewage sludge treatment technique.
In order to achieve the above object; The wool washing sewage sludge treatment technique that the present invention designed; Sewage is handled through air flotation pool, oxygen compatibility pool, Aerobic Pond and settling tank; Wherein when air flotation pool, add compound iron and organic cation polymeric flocculant, the back of finishing dealing with adds alkali lye in sewage makes pH value reach 7.5 back entering oxygen compatibility pools, and the D0 value is controlled at 3.5 in Aerobic Pond simultaneously.The characteristics of this technology are to utilize the chemical action of pneumatically supported physical action and compound iron and organic cation polymeric flocculant, reach simultaneously to reclaim yolk and handle flocculation mud, and reducing COD of sewage is worth effect.
In order further to reduce chemical action sewage ph is worth influence, described compound iron is the mixture of ferrous sulfate, ironic hydroxide and iron trichloride, described organic cation polymeric flocculant cationic polyacrylamide.
The resulting wool washing sewage sludge treatment technique of the present invention through the acting in conjunction of physics with chemistry, has been accomplished the work that yolk reclaims and disposes of sewage simultaneously when air flotation pool, simplified technology effectively.Owing to used compound iron, make that the ph value rising of sewage is comparatively not obvious on the other hand, make the follow-up alkali adjustment ph value work materials consumption that adds reduce greatly, and the treatment effect of mikrobe remains unchanged, and has finally reached the purpose that reduces processing cost.Because the generation of mud descends 25%～30%, make the processing cost of mud descend, practiced thrift cost from another point of view.

Embodiment
Combine accompanying drawing that the present invention is done further description through embodiment below.
Embodiment 1:
As shown in Figure 1; Present embodiment describe the wool washing sewage sludge treatment technique; Sewage is handled through air flotation pool, oxygen compatibility pool, Aerobic Pond and settling tank; Wherein when air flotation pool, add compound iron and organic cation polymeric flocculant, the back of finishing dealing with adds alkali lye in sewage makes pH value reach 7.5 back entering oxygen compatibility pools, and the D0 value is controlled at 3.5 in Aerobic Pond simultaneously.Wherein said compound iron is the mixture of ferrous sulfate, ironic hydroxide and iron trichloride, described organic cation polymeric flocculant cationic polyacrylamide.
