Electrocoagulation/slow decarburization combined water treatment device

Abstract

The invention discloses an electrocoagulation / slow decarburization combined water treatment device. The device comprises an electrocoagulation reactor and a slow decarburization process water treatment appliance, wherein the electrocoagulation reactor comprises an electrocoagulation reaction tank, an electrocoagulation reaction appliance and an electrocoagulation power distribution cabinet, the electrocoagulation reaction appliance is arranged in the electrocoagulation reaction tank, and the electrocoagulation reaction appliance is connected with the electrocoagulation power distribution cabinet; the slow decarburization process appliance includes a condensation pool, a flocculation tank and a sloping plate sedimentation tank, the sloping sedimentation tank includes a plug flow zone, a pre-precipitation zone, a sloping plate zone and a sludge concentration zone, and the electrocoagulation reaction tank communicates with the condensation pool; the flocculation tank communicates with thebottom of the condensation pool, the flocculation tank communicates with the plug flow zone, and the plug flow zone is connected with the pre-precipitation zone; and the pre-precipitation zone is connected with the sloping plate zone. The electrocoagulation / slow decarburization combined water treatment device has a perfect supporting control system, high degree of automation and simplified installation of the appliance, and the cost of operation and investment is saved; and the treatment effect is good so that the requirements of softening and clarification pretreatment processes of wastewater can be met, and meanwhile addition of a coagulant and an assistant coagulant is reduced so that safe operation of the subsequent membrane treatment process system can be ensured effectively.

Description

technical field [0001] The invention belongs to the field of water treatment, in particular to an electrocoagulation-slow decarburization combined water treatment equipment. Background technique [0002] The principle of electron flocculation reaction is that under the external power supply, an electric field is generated between specific electrode plates, and the charged particles such as fine charged particles, colloids, macromolecular proteins, virus particles, and cells in the water move and collide directionally under the action of the electric field force. As a result, the double electron layer of charged particles is compressed and destabilized, and then rapidly flocculates into large-size flocs and precipitates. At present, the commonly used electrocoagulation reactor in the field of wastewater treatment is a horizontal fixed pole type, and most of them combine electrocoagulation with other water treatment equipment, such as cyclone clarifiers. There are many defect...

AI Technical Summary

Problems solved by technology

There are many defects in the combined process system of electrocoagulation and cyclone clarifier. First of all, this type of electrocoagulation reactor is not suitable for treating wastewater with high suspended solids content, and it is easy to block, short flow, high cost and complicated equipment installation. Defects; Secondly, the ordinary cyclone clarifier has low clarification efficiency and poor water discharge effect, and is only suitable for single wastewater treatment systems such as coal slime water.
