Electromagnetic coupling inclined plate electric flocculation reactor

Abstract

The invention provides an electromagnetic coupling inclined plate electric flocculation reactor. A casing of the reactor is made by adopting PPR or PVDF and other corrosion-resistant and high-temperature-resistant materials; the interior of the reactor is divided into an electromagnetic zone and an inclined plate electric flocculation zone which are mutually insulated, wherein the electromagnetic zone comprises a plurality of groups of electromagnets, the inclined plate electric flocculation zone comprises a set of inclined plate zigzag electrodes, and iron electrode or aluminium electrodes are adopted as the electrodes. The plurality of groups of electromagnets and the electrodes are connected in series; when direct current passes, the electromagnets generate a magnetic field with certain intensity, the electrodes generate ferrous or aluminous hydroxide flocculating agents under the action of the current, a certain amount of the magnetic powder is added into the reactor and is mixed with the ferrous or aluminous hydroxide flocculating agents to form magnetic floccule, and the magnetic floccule under the action of electromagnetic force and the inclined plate electrodes settle rapidly in a frustum-shaped sludge-collecting hopper at the bottom of the reactor. Compared with a traditional electric flocculation device, the reactor has the advantages of small size, short flocculation time, large treatment amount, and the like.

Description

technical field [0001] The invention relates to an electro-coagulation reactor with an electromagnetically coupled inclined plate, which is suitable for treating wastewater with high suspended matter, and belongs to the professional field of environmental engineering. Background technique [0002] Coagulation-sedimentation technology is an indispensable key link in the field of water treatment. Both water supply and drainage treatment cannot do without coagulation-sedimentation technology. The coagulation-sedimentation Coagulant coagulation sedimentation and electrocoagulation sedimentation, in which flocculant and coagulant aid are added. The coagulation sedimentation process principle is to add an appropriate amount of inorganic salt flocculants such as polyaluminum chloride, ferric chloride, and polyferric sulfate to the water body. , using a large number of charged flocs produced by the hydrolysis of iron ions or aluminum ions, the tiny solid particles and some organic m...
