Electric flocculation device

Abstract

The embodiment of the invention discloses an electric flocculation device. The electric flocculation device comprises an electrolytic tank, wherein the electrolytic tank is internally provided with a cathode plate and an anode plate, and at least one bipolar electrode is also arranged between the anode plate and the cathode plate; and the electric flocculation device is characterized in that the bipolar electrode is a bulk metal electrode, the bulk metal electrode is placed in a load bearing component, and the load bearing component is provided with a through hole. Through the using of the bulk metal electrode, the surface areas of the electrodes are greatly increased, and thus the electrodes are not easy to passivate.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an electroflocculation device. Background technique [0002] Electrocoagulation devices can be widely used in various industries of wastewater treatment. Such as electroplating industry wastewater, slaughterhouse wastewater, food and beverage factory wastewater, petrochemical factory wastewater, oil field wastewater, pharmaceutical factory wastewater, mining wastewater, landfill leachate wastewater treatment, agricultural wastewater, petrochemical, paint dye, dyeing and finishing industries, etc. , Cooling water tower wastewater, ship bilge sewage purification, port catchment area purification, wood treatment wastewater, domestic sewage treatment in tourist scenic spots, etc. [0003] In the prior art, many use such as figure 1 The shown electroflocculation device with parallel water flow between plates includes a DC power supply 101, a holding chamber 102 and a plural...

AI Technical Summary

Problems solved by technology

However, there are the following problems: 1) It is inconvenient to replace the plate after the electrode is consumed, and new materials must be used, and the design and manufacturing cost is high; 2) The surface area of ​​the electrode is small, and it is easy to passivate; 3) The current distribution on the electrode is not uniform, and the processing efficiency is not high.

[0004] Therefore, in view of the above-mentioned defects in the current prior art, it is necessary to conduct research to provide a solution to solve the defects in the prior art, avoiding the inconvenient replacement of the plates after the electrodes are consumed, and new materials must be used , high design and manufacturing costs; small electrode surface area, easy passivation; uneven current distribution on the electrode, low processing efficiency
