Flocculation assembly line

Abstract

The invention relates to the field of wastewater treatment. The invention particularly relates to a flocculation assembly line, which comprises an electrolytic tank, at least one group of electrode plates are arranged in the electrolytic tank; wherein the electrode plate comprises a first electrode plate and a second electrode plate which are oppositely arranged, and further comprises a stage reversing device, the stage reversing device comprises a stage reversing device and a stage reversing device, the first electrode plate and the second electrode plate are electrically connected with the stage reversing device and the stage reversing device respectively, the service life is long, and dirt is easy to clean. According to the flocculation assembly line, the polarities of the stage reversing device and the stage reversing device are changed through the stage reversing device; and the polarities of the first polar plate and the second polar plate forming each group of electrode plates in each electrolytic tank are in turn positive and negative, so that the condition that one polar plate is quickly corroded and the other polar plate is quickly wrapped is avoided on the premise of notinfluencing the flocculation reaction, the efficiency of the flocculation reaction is greatly improved, and the service life of the polar plates is prolonged.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a flocculation assembly line. Background technique [0002] Flocculation refers to the aggregation of suspended particles in water or liquid or the formation of flocs, so as to accelerate the coagulation and sedimentation of particles and achieve the purpose of solid-liquid separation. [0003] Usually the flocculation process has the following reactions: [0004] (1) Electrolytic oxidation [0005] Oxidation in the electrolysis process can be divided into direct oxidation, that is, pollutants directly lose electrons at the anode to oxidize; and indirect oxidation, using anions with lower electrode potential in the solution, such as OH-, Cl-, to lose electrons at the anode to generate Active substances of new stronger oxidizing agents such as [O], [OH], Cl2, etc. Use these active substances to oxidize and decompose BOD in water 5 , COD, NH 3 -N etc. [0006] (2) Electrol...

AI Technical Summary

Problems solved by technology

[0013] However, the common electroflocculation equipment mostly has the following defects in use: 1. The service life of the electrode plates is low, especially one of the plates will be wrapped by flocs in a short time, while the other plate will be Severe corrosion; 2. In the tank used for flocculation reaction, a thick dirt layer is easy to form on the upper part, which is difficult to clean, and these bulky dirt layers will greatly reduce the speed of flocculation reaction
