Fluid bed three-dimensional electrode reactor for treating organic waste water

Abstract

The fluidized bed 3D electrode reactor for treating organic waste water includes a reaction bed body, a circulating filter pump, an air pump, a power source, and porous metal feeding electrodes and granular electrodes connected to the power source. It features that of the at least three porous metal feeding electrodes, at least one is active electrode capable of oxidizing and decomposing the organic matter inside the waste water, all are connected to the cathode and the anode of the power source and arranged inside the reaction bed body, and two adjacent ones are supported with anticorrosive insulating material and filled with granular electrodes. The present invention has high waste water treating efficiency, small size, simple operation, low treating cost and other advantages.

Description

technical field [0001] The invention relates to a treatment device for removing organic substances in organic wastewater by electrolytic oxidation, in particular to a fluidized bed three-dimensional electrode reactor which adopts fluidized bed three-dimensional electrode technology to improve COD removal efficiency and is suitable for industrial organic wastewater treatment . Background technique [0002] Many industrial production processes will produce a large amount of waste water containing organic matter. If these waste water are discharged directly without treatment, they will cause very serious harm to the environment. Therefore, the treatment of organic waste water has become an urgent problem to be solved in the field of environmental protection technology at home and abroad. a puzzle. Using the chemical reaction of the electrolysis process is one of the sewage treatment methods to remove harmful impurities in industrial sewage in the form of conversion. It is curr...

But it has the problem that the cost of processing is greatly increased due to the addition of chemical agents

Chinese patent (Patent Publication No. CN 1358672A) discloses a three-dimensional electrode reactor and its method for treating organic wastewater. It is mainly aimed at high-concentration organic wastewater, using electric energy to excite particle electrodes to generate strong oxidants, so as to decompose wastewater. The purpose of organic matter; but because the particle electrode needs to produce a strong oxidant, there is a problem of oxidizing and decomposing the organic matter while oxidizing and decomposing itself, which makes the life of the particle electrode particularly short and virtually increases the cost of wastewater treatment
