Embodiment 1

[0029] Please refer to figure 1 As shown, the embodiment of the present invention discloses a sewage treatment system that combines magnetic coagulation separation and biological treatment. The disclosed sewage treatment system includes a magnetic separation device 7, a regulating tank 8 and a biological filter; the effluent of the magnetic separation device 7 The end is connected with the water inlet end of the regulating pool 8, the water outlet end of the regulating pool 8 is connected with the water inlet end of the biofilter, and the regulating pool 8 is used for regulating the flow of the magnetic separation device 7 and the biofilter.

[0030] Among them, the sewage first enters the coagulation reaction device 6 to react with the flocculation agent and magnetic seeds to form magnetic flocs, and then the magnetic flocs are quickly separated by the magnetic separation device 7, so that organic matter (COD), total phosphorus (TP) and Suspended solids (SS) reduce the concen...

Embodiment 2

[0052] Based on the sewage treatment system disclosed in Example 1, the embodiment of the present invention also discloses a sewage treatment process, and the disclosed sewage treatment process includes the following steps:

[0053] (1) The sewage in the sewage pool 1 is transported to the coagulation reaction device 6 after passing through the sewage filtration device, and the sewage reacts with the added flocculation agent and magnetic species in the coagulation reaction device 6 to form magnetic flocs:

[0054] (2) The sewage containing magnetic flocs is transported from the coagulation reaction device 6 to the magnetic separation device 7, and the magnetic flocs in the sewage are adsorbed and separated by the magnetic force of the magnetic separation device 7;

[0055] (3) The separated water processed by the magnetic separation device 7 is transported to the regulating tank 8, and is transported to the biological filter after being controlled by the regulating tank 8 for w...

Abstract

The invention discloses a sewage treatment system and process combining magnetic coagulation separation and biological treatment. The sewage treatment system comprises a magnetic separation device, aregulating tank and a biological filter tank; the water outlet end of the magnetic separation device is connected with the water inlet end of the regulating tank, the water outlet end of the regulatingtank is connected with the water inlet end of the biological filter, and the regulating tank is used for regulating the flow of the magnetic separation device and the biological filter tank; sewage is conveyed to a coagulation reaction device for coagulation reaction to form magnetic flocs, then the magnetic flocs are conveyed to the magnetic separation device to be adsorbed and separated, then the magnetic flocs are conveyed to the regulating tank, and the magnetic flocs are conveyed to the biological filter tank after regulating and controlling the water quantity through the regulating tank. According to the scheme, the problems that in the actual use process of an existing sewage treatment system, the working frequency of a backwashing unit is high, so that the treatment efficiency isinfluenced, and the backwashing water consumption and the system energy consumption are increased can be solved; and the problem that the working stability of each treatment unit is poor due to the fact that the treatment units are easily influenced by fluctuation of water quantity, water quality and the like is solved.

Description

technical field [0001] The invention relates to the technical field of sewage, in particular to a sewage treatment system and process combining magnetic coagulation separation and biological treatment. Background technique [0002] The magnetic coagulation separation technology is to add magnetic powder to the traditional coagulation sedimentation process, so that it can be integrated with the flocculation of the sewage in the sewage, and then the magnetic flocs in the sewage are adsorbed and separated under the magnetic field of the external magnetic separation system. , so as to achieve the purpose of water purification. [0003] With the application and development of this technology, in order to enable the magnetic coagulation separation system to carry out advanced treatment of sewage and remove nitrogen, phosphorus and soluble micro-pollutants in sewage, a patent document with the publication number "CN106673373A" discloses a A sustainable and efficient sewage treat...
