Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027] Such as figure 1 As shown, the present invention provides a high-salt and high-organic-matter wastewater recycling zero-discharge treatment device, which includes a yin chamber circulation unit 1, a resource recycling module 2 and a positive chamber circulation unit 3, and the resource recycling module 2 is connected with the yin chamber circulation unit 1 respectively. Connected with the anode circulation unit 3 , the resource recovery module 2 includes a box body 21 , a membrane stack 22 arranged inside the box body 21 for redox reactions, and a power supply 23 connected to the box body 21 .

[0028] The wastewater entering the anode chamber of the resource module 2 undergoes an oxidation reaction. The oxidation reaction includes direct oxidation and indirect oxidation. The direct oxidation reaction occurs when electrons are lost in the anode chamber. The organic ...

Abstract

The invention relates to a zero-discharge recycling treatment device for wastewater with high salinity and high organic substance content, relates to the technical field of treatment of high-salinity wastewater and solve the technical problems that treatment is large in investment and high in operation cost and cannot realize expected purification effect in the prior art. The zero-discharge recycling treatment device for wastewater with high salinity and high organic substance content comprises a cathode chamber circulating unit, a recycling module and an anode chamber circulating unit, wherein wastewater entering the recycling module can be subjected to a redox reaction by means of a membrane stack in the recycling module, so that the chemical oxygen demand can be reduced, and organic substances in the wastewater can be degraded effectively; besides, salts in wastewater can be recycled well by means of electrochemical principles, and zero-discharge recycling is realized.

Description

technical field [0001] The invention relates to the technical field of high-salt wastewater treatment, in particular to a zero-discharge treatment device for recycling high-salt and high-organic-matter wastewater. Background technique [0002] High-salt and high-organic waste water refers to waste water containing high concentrations of soluble inorganic salts and organic matter (generally waste water with a salinity greater than 3%). Due to the shortage of water resources, the wastewater discharged from petroleum, chemical, pharmaceutical and other heavy polluting industries often contains high concentrations of soluble inorganic salts and refractory or toxic organic pollutants, which has caused tremendous pressure on the living environment. In addition to high concentrations of salts, industrial wastewater also contains high concentrations of organic matter, and chemical oxygen demand (COD) is often used as an indicator to measure the content of organic matter in water. T...
