Description
Technical Field
The invention relates to the technical field of sewage treatment, in particular to a multistage circulating sewage treatment device.
Background
Sewage treatment is a process of purifying sewage to meet the water quality requirement of discharging the sewage into a certain water body or reusing the sewage. Sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like, and is classified according to sewage sources, and sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. The production sewage comprises industrial sewage, agricultural sewage, medical sewage and the like, and the domestic sewage is sewage generated in daily life and refers to complex mixtures of various forms of inorganic matters and organic matters.
At present, in sewage treatment, the composite flocculant which is prepared by dissolving polyaluminium chloride and polyacrylamide together is more and more widely applied, the fundamental difference from the traditional inorganic coagulant is that the traditional inorganic coagulant is low molecular crystal salt, the polyaluminium chloride has a structure consisting of multi-carboxyl complex with various forms, has wide applicable PH value range, has no corrosion to pipeline equipment, has obvious water purification effect, can effectively remove heavy metal ions such as chromatics SS, COD, BOD, arsenic, mercury and the like in water, the product is widely used in the fields of drinking water, industrial water and sewage treatment, and treatment of special water quality (such as oily sewage, printing and dyeing and papermaking sewage, smelting sewage, radioactive substance-containing toxic metal such as Pb and Cr, F-containing sewage, and the like), however, the existing sewage treatment equipment has the following defects in the use of the composite flocculant in which the polyaluminium chloride and the polyacrylamide are dissolved together: 1. the composite flocculant which is prepared by dissolving polyaluminium chloride and polyacrylamide together is only used once, after precipitation, the composite flocculant is conveyed to sludge treatment equipment along with sludge for treatment, but an effective flocculant still exists in the sludge at the moment, if the composite flocculant is directly conveyed to the sludge treatment equipment along with the sludge for treatment, resources are seriously wasted, the flocculant is not fully utilized, and the cost of sewage treatment is increased; 2. in the prior art, when adding polyaluminium chloride and polyacrylamide, usually, the polyaluminium chloride and polyacrylamide solution are directly added at the top of a flocculation tank, and the polyaluminium chloride and polyacrylamide solution can be fully mixed with sewage by increasing the stirring time, so that the sewage treatment efficiency can be reduced; 3. in the prior art, a stirring shaft in a flocculation tank usually only axially rotates, the stirring dead angle is large, and the flocculation effect is reduced because polyaluminium chloride and polyacrylamide solution are not sufficiently mixed with sewage; 4. after the polyaluminium chloride and polyacrylamide solution are mixed with sewage, a large amount of time is spent on standing and precipitating, and when the flocculated sludge is precipitated to the bottom, the supernatant is conveyed to the next procedure, so that the sewage treatment efficiency is greatly reduced.
