Embodiment 1

[0027] As shown in Figure 1, the sewage treatment device includes a reactor 3 (including a coagulation reaction zone 4 and a dynamic membrane zone 5), a dynamic membrane 6, a water distribution pipe, a deflector 7 in the coagulation reaction zone 4, an aeration pipe 9, 10. Sewage treatment methods are as follows:

[0028] The sewage is directly introduced into the reactor, and the coagulant PAC (polyaluminum chloride) is added into 2 from the top of the coagulation reaction zone 4. In the coagulation reaction zone 4, the sewage and the added coagulant are exposed on the bottom side of the coagulation reaction zone Mixing under the action of air, the aeration volume of the aeration tube at the bottom of the coagulation reaction zone is 0.03m 3 / m 3 min. Circulation is formed in the entire reactor, and the sewage that is fully mixed with the coagulant can form a circulation in the reactor, and the treated water passes through the dynamic film formed on the non-woven fabric su...

Embodiment 2

[0030] As described in Example 1, the difference is that the substrate 6 is sieve silk, and the coagulant is APAM (anionic polyacrylamide). The aeration volume of the aeration tube at the bottom of the coagulation reaction zone is 0.05m 3 / m 3 min.

Embodiment 3

[0031] Embodiment 3: As described in Embodiment 1, the difference is that the substrate 6 is a screen, and the coagulant is selected from CPAM (cationic polyacrylamide). The aeration volume of the aeration tube at the bottom of the coagulation reaction zone is 0.02m 3 / m 3 min.

Abstract

The intensified coagulation and dynamic film integrated waste water treating process belongs to the field of environment engineering technology. The integrated waste water treating process includes aeration for the full mixing and reaction between waste water and chemical, coagulating reaction to produce flock, and filtering in the base material to form flocculating layer and filter cake layer possessing microfiltering effect, so as to eliminate most of the pollutant from waste water. The said process has the capacity of eliminating most organic pollutant, small covered area and high efficiency.

Description

technical field [0001] The invention relates to a sewage treatment process, in particular to an integrated sewage treatment process of enhanced coagulation and dynamic membrane, and belongs to the technical field of environmental engineering. Background technique [0002] Enhanced coagulation is a water treatment process developed on the basis of conventional coagulation and based on the development of new coagulants. It improves the pollution by increasing the dosage of coagulants or optimizing coagulants or optimizing operating parameters. process of removal rate. Compared with the traditional primary treatment, the size of the sedimentation tank required by the enhanced coagulation process is only half that of the traditional primary treatment, that is, the enhanced coagulation process can treat twice as much sewage as the traditional primary treatment under the same volume of the sedimentation tank. This is very meaningful for water bodies with serious water pollution, ...
