Electrochemical degradation device in modularized serial connection

Abstract

The invention discloses an electrochemical degradation device in modularized serial connection. Grooves are respectively arranged on the side surfaces of end modules, N type A middle modules and (N-1) type B middle modules, lower and upper water pass small holes are respectively arranged on the two types of the middle modules, the grooves arranged on the end modules are communicated with a water inlet pipe, after the two types of middle modules are ranged at intervals, the end modules and end plates are arranged at both sides of the middle modules, then, screw rods and screw nuts are used for fastening, all modules are sequentially communicated through the lower water pass small holes or the upper water pass small holes, an electrode group with alternately ranged anodes and cathodes is respectively arranged in each module, the anodes and the cathodes are respectively and mutually connected in the same electrode group, the anodes in the end modules are connected with a positive electrode of a power supply, the cathodes in the type A middle modules next to the end plates are connected with a negative electrode of the power supply, and water discharge pipes are respectively arranged at the bottoms of the modules. The serial connection grade number of the electrochemical degradation device can be freely regulated according to requirements, and the modules in the same dimension are utilized and can be assembled into the degradation device with different treatment capabilities. The electrochemical degradation device can be used for the electrochemical degradation treatment on the industrial waste water.

Description

technical field [0001] The invention relates to an electrochemical degradation device, in particular to a modular series electrochemical degradation device for industrial waste water treatment. Background technique [0002] With the rapid development of industry, the number and types of organic pollutants entering water through various channels have increased sharply, causing serious pollution to the water environment and directly threatening human health. Especially the wastewater produced by chemical industry, dyestuff, pharmaceutical, printing and dyeing, coking and other industries, because the molecular structure of the organic pollutants contained is relatively stable, the effect of conventional physical chemical and biochemical methods is very poor. Electrochemical degradation is a new wastewater treatment technology that relies on electrolysis to generate strong oxidants to oxidize various pollutants. Compared with conventional physicochemical and biochemical method...
