Problems solved by technology

[0004] However, the above-mentioned prior art has the following defects: the biggest obstacle in the use of electrocoagulation is the passivation of the plate, and a non-conductive passivation layer will be formed on the surface of the anode during operation. In addition, some impurities in the sewage will adhere to On the surface of the electrode, the cell voltage increases, the energy consumption of electrocoagulation increases, and the efficiency decreases

Abstract

The invention relates to a pulse electrolysis reactor. The pulse electrolysis reactor includes an electrolysis cell body, a plurality of electrode plates and a pulse power supply, an electrolysis space is formed in the electrolysis cell body, and the plurality of electrode plates are arranged in the electrolysis space at intervals along the flow direction of sewage so that sewage overflows from the bottom of each electrode plate to the top of the electrode plate to one of the electrode plates downstream, and the pulse power supply is electrically connected to at least two of the electrode plates, so that The opposite sides of each of the electrode plates have different polarities respectively. The pulse electrolysis reactor consumes less energy and has higher efficiency. The invention also provides an industrial sewage treatment system.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, more specifically, it relates to a pulse electrolysis reactor and an industrial sewage treatment system. Background technique [0002] In the face of conventional urban domestic sewage, the existing technical means can basically make it discharge up to the standard. However, the wastewater from the chemical industry, especially the fine chemical industry, has the characteristics of complex composition, high concentration of salt and pollutants, high biological toxicity, and refractory degradation. In the current field of sewage treatment in the chemical industry, the method of treating sewage with electrochemical principles is currently recognized as an efficient, stable and non-secondary pollution method, such as electro-Fenton and electro-flocculation. [0003] For example, Chinese Patent Publication No. CN107827209A provides an electrocoagulation wastewater treatment device and an el...
