Abstract

The invention provides a difficult-to-degrade waste water treatment device reinforced by up-flow type anaerobic and biocatalysis electrolysis coupling and relates to a difficult-to-degrade waste water treatment device. The problems in the prior art, such as low toxic waste water treatment efficiency, weak toxicity enduring capability and stability deficiency, are solved. The device consists of a reactor main body, a cover plate, a water distribution plate, a titanium wire, a cathode, an anode, a reference electrode, a resistor and a power supply, wherein one water inlets are respectively formed in the left and right two sides of the lower part of the reactor main body, water outlets are respectively formed in the left and right two sides of the upper part of the reactor main body, a gas collecting hole is formed in the top end of the reactor main body, and a sampling opening is formed in the front of the reactor main body; the water distribution plate, the cathode and the anode are arranged in the reactor main body, and the anode is higher than the cathode. The device adopting an integrated diaphragm-free anaerobic and biocatalysis electrolysis system has the characteristics of an anaerobic organism process and a biological electrochemical process, and is low at cost and high in volumetric load. The device is used for treating difficult-to-degrade toxic waste water.

Description

technical field [0001] The invention relates to the application of a device for treating refractory wastewater. Background technique [0002] In recent years, with the rapid development of my country's economy, the industrial industry, which is the pillar of the economy, has developed particularly rapidly, and the resulting environmental problems have become more and more serious. The wastewater problem has become a research hotspot and difficulty in the environmental field. The main characteristics of industrial wastewater are: complex sources, large fluctuations in water quality and quantity, and containing a large number of toxic and difficult-to-biodegrade pollutants. Although the treatment technology of industrial wastewater has been developed for several decades and several generations, and a number of well-formed and widely used treatment technologies have emerged, it is still difficult to deal with the increasing amount of high-concentration, refractory, and biologic...
