Sewage efficient flocculation clarification device

Abstract

The invention discloses a sewage efficient flocculation clarification device, which comprises an electric flocculation reaction cavity and a clarification separation cavity in matched arrangement on the periphery of the flocculation reaction cavity, wherein a water inlet pipe is arranged at the upper end of a casing of the clarification separation cavity; the water inlet pipe passes through the clarification separation cavity to be communicated with a tangent line of a side wall of the casing of the electric flocculation reaction cavity; a plurality of electric flocculation electrode plates are arranged inside the electric flocculation reaction cavity in a matched way, and are used for electrolyzing and flocculating the waste liquid so that the waste liquid realizes purification and impurity removal in the cyclone state through electric flocculation reaction; after flocculation impurities generated through the electrolyzing flocculation by the electric flocculation reaction cavity aredecomposed in the clarification reaction cavity, the discharge can be realized through a pollution discharge opening; treated waste water enters the water outlet pipe through an overflow weir arrangedon the top of the flocculation reaction cavity to enter the water outlet pipe to flow out. The sewage efficient flocculation clarification device effectively solves the problems that the water outletwater flow of the existing single cavity electric flocculation reaction cavity is instable; flocculation impurities can be easily clamped to cause the problems of reverse pollution or equipment wateroutlet pipe blockage and the like; the water outlet water quality purification degree and the water outlet water flow stability after the electric flocculation reaction impurity removal can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a sewage high-efficiency flocculation and clarification device for wastewater treatment. Background technique [0002] With the development of modern human society, a huge amount of domestic wastewater and industrial wastewater is generated every day. Among them, industrial wastewater contains a large amount of acidic or alkaline pollutants, if discharged directly without treatment, it is bound to pollute the environment and endanger human health. For this reason, wastewater purification treatment and recovery technology has become one of the necessary technologies for industrial production. [0003] At present, electrocoagulation reaction has been commonly used in the purification treatment of wastewater. Wastewater treatment methods include physical methods, chemical methods and biological methods, physical methods, such as adsorption; chemical methods, such as o...

Problems solved by technology

Due to the limited internal volume of the above-mentioned single-chamber reaction vessel, it is difficult to ensure the stability of the effluent flow under the action of agitation, and it is also easy to cause flocculated impurities to flow out of the water outlet together with the water flow, which affects the quality of the effluent after treatment and reduces equipment operation. efficiency
