Embodiment Construction
[0012] like figure 1 As shown, the sewage treatment integrated device includes a device shell 1, a water inlet 2, a chemical dosing port 3, a static pipeline mixer 4, a motor 5, a stirring paddle 6, an ultraviolet lamp 7, a magnetic field 8, a water outlet baffle 9, Water outlet 10, mud discharge pipe 11, control valve A12, magnetic separator 13, mud outlet 14, control valve B15, magnetic flocculant return pump 16, delivery pipe 17, control valve C18, tee pipe 19.
[0013] When the device is working, the motor and the ultraviolet lamp work at the same time under the same power supply system, the sewage enters from the water inlet, and at the same time, the photomagnetic catalytic material and flocculant are added from the chemical dosing port. The pipe mixer is mixed for 5-10 seconds, and then enters the interior of the device. Under the condition of ultraviolet light, the photomagnetic catalytic material and sewage react to treat sewage. At the same time, the photomagnetic ca...

The present invention relates to a magneto-optical sewage treatment apparatus, and belongs to the field of sewage treatment equipment. The apparatus comprises a housing, a water inlet, an agent addition port, a static pipeline mixer, a motor, a stirring paddle, an ultraviolet lamp, a magnetic field, an effluent baffle, a water outlet, a mud discharging pipe, a control valve, a magnetic separator, a control valve, a mud outlet, a magnetic flocculant reflux pump, a conveying pipe, a control valve and a three-way pipe. According to the present invention, based on a combination effect of photocatalysis and magnetic flocculation of a magneto-optical catalysis material, under a controlled magnetic field effect, one part of polluting substances in sewage is degraded through photocatalysis, the other part of polluting substances in sewage forms a magnetic floc, and the magnetic floc is subjected to rapid sedimentation removal so as to achieve a sewage purification effect; a magnetic separation device and a conveying device are adopted to achieve separation and recovery utilization of the magneto-optical catalysis material and the magnetic flocculant; and with the magneto-optical sewage treatment apparatus, photocatalysis, flocculation, precipitation and magneto-optical catalysis material recovery utilization are integrated, and characteristics of simple structure, convenient operation, significant treatment and small occupation area are provided.
Description
technical field [0001] The invention belongs to the field of sewage treatment equipment, and in particular relates to an optical-magnetic sewage treatment integrated device. Background technique [0002] Photocatalytic oxidation is a water treatment technology that has only emerged in the past 20 years. It can usually completely mineralize organic matter into CO in sufficient reaction time. 2 and H 2 O and other simple inorganic substances avoid secondary pollution, are simple and efficient and have a promising future. In the water treatment process, in order to speed up the reaction rate of water treatment and improve the reaction efficiency, catalysts or flocculants are often added to the water. In order to further improve the efficiency of water purification, catalysts and flocculants with larger specific surface areas are usually used, especially in recent years. Although the introduction of nano-materials has achieved good water purification effects, it is difficult t...
