Embodiment Construction

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] Such as figure 1 As shown, the process includes magnetic photocatalysis, magnetic flocculation, magnetic separation, magnetic catalyst circulation, and sludge press filtration dehydration.

[0014] Such as figure 2 As shown, in the photocatalytic reactor, the sewage mixed with magnetic photocatalyst enters the reactor, passes through the cone-shaped top cover 3, and the sewage is sprayed in an umbrella state, and the photocatalysis is carried out under the irradiation of the ultraviolet lamp 2, and the organic matter is oxidized break down.

[0015] Such as figure 1 , 2 As shown, the sludge enters the magnetic flocculation tank after photocatalysis, and the magnetic seeds, coagulant (PAC) and coagulation aid (PAM) are added in sequence. Under the action of mechanical stirring, within 3 minutes, through the micro-flocculation process,...

Abstract

The invention discloses a photo-catalytic synergistic magnetic separation sewage treatment device and method. The photo-catalytic synergistic magnetic separation sewage treatment method comprises photo-catalytic reaction, micro-flocculation, disk magnetic separation, magnetic medium circulation and the like; an ultraviolet lamp group is arranged inside a photo-catalytic reactor; sewage enters froma water inlet pipe of the reactor; a magnetic photo-catalyst reacts with pollutants in the sewage under the irradiation of ultraviolet light and enters a micro-flocculation pool after photo-catalyticreaction, so that impurities in wastewater are attached to the surface of a magnetic medium and are removed by a fixed slag scraping device under the action of the magnetic force of a disk drive, andthe water purifying purpose is achieved. The photo-catalytic synergistic magnetic separation sewage treatment device and method disclosed by the invention have the benefits that the pollutants in thesewage are effectively removed under the actions of photo-catalysis, flocculation, a magnetic field and the like; the magnetic photo-catalyst can also be recovered and has a wide market application prospect; the magnetic medium, namely 'laterite', can achieve the purpose of treating wastes with wastes; the fixed slag scraping device is adopted for removing slag and has the advantages that the cost is low, a magnetic disk selects a permanent Rufe Boron magnet with extremely-high magnetic property, and the like compared with a traditional slag discharge device.

Description

technical field [0001] The invention relates to sewage treatment, in particular to a photocatalytic cooperative magnetic separation sewage treatment device and method. Background technique [0002] With the development of industry and economy, a large amount of discharged water continuously enters the environment, which contains toxic and harmful substances that are difficult to biodegrade, which brings great harm to industrial and agricultural production, people's life and human health. How to effectively dispose of these polluted water has become a hot spot in the field of environment. At present, adsorption, ultraviolet oxidation, ozone oxidation, chemical degradation, biodegradation and other technologies are usually used for treatment. However, in the conventional water treatment methods, the physicochemical method has the disadvantages of complex process flow, high cost, difficult regeneration of adsorbent, incomplete degradation, and easy generation of secondary poll...
