Abstract

The invention discloses a non-diaphragm upflow type continuous flow bio-electrochemical apparatus for treating difficultly degraded waste water, which relates to an apparatus for treating waste water. The invention is used for solving the technical problems of high cost and low efficiency of BESs. A housing is fixedly connected with a base plate, a lower separator plate, a cathode, an upper separator plate, an anode and a top plate from the bottom to the top. According to the invention, present bio-electrochemical reactors are greatly improved, and according to the characteristics of waste water, the electrode positions are reasonably arranged, thereby pollutants which are difficult to be degraded in water are effectively detoxified at the cathode firstly, then the pollutants in water are further degraded by the effect of anodization, and the difficultly degraded waste water treatment efficiency is improved greatly. In addition, the invention employs a non-diaphragm design, thereby not only reducing internal resistance of the reactor, but also reducing cost, which are beneficial to the extension and engineering of the reactor.

Description

technical field [0001] The invention relates to a waste water treatment device. Background technique [0002] With the rapid development of industrialization, the water consumption and wastewater discharge of industrial enterprises are increasing day by day. Coking, printing and dyeing, petrochemical, oil refining, coal chemical and pharmaceutical wastewater are typical toxic and refractory organic wastewater. These wastewaters are usually Contains high concentrations of biochemically refractory organic pollutants, which pose serious hazards to environmental water bodies and are difficult to treat. In addition, with the enhancement of human awareness of environmental protection, the emphasis on the water environment and the understanding of the accumulation of toxic substances in organisms, the restrictions on the discharge of toxic substances into water bodies are becoming more and more stringent. Conventional biological and physical and chemical purification methods are us...
