Treatment device and method for organic high-concentration wastewater

Abstract

The invention discloses a treatment device and method for organic high-concentration wastewater. The treatment device for the organic high-concentration wastewater comprises a machine body, a dreg scraping machine and a plurality of groups of electrochemical water treatment units, wherein the machine body is internally provided with a mud storage chamber, an electrochemical reaction chamber and awater inlet chamber; the water inlet chamber is arranged at the left lower part of the electrochemical reaction chamber; the water inlet chamber is communicated with the electrochemical reaction chamber; a water inlet is formed in the water inlet chamber; the plurality of groups of electrochemical water treatment units are arranged at the bottom of the electrochemical reaction chamber; the dreg scraping machine is mounted at the top in the machine body; the mud storage chamber is arranged at the left upper part of the machine body; the mud storage chamber is arranged at one side of the dreg scraping machine; a mud discharging opening is formed in the bottom of the mud storage chamber; a water outlet is formed in the bottom of the right end of the machine body. The treatment device disclosed by the invention is reasonable in design, scaling and blocking conditions on the surface of an electrode can be avoided, the treatment efficiency is higher and the treatment energy consumption is lower.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a treatment device and method for organic high-concentration wastewater. Background technique [0002] With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Since the composition of industrial wastewater is more complex, and some are toxic, industrial wastewater treatment is more difficult and more important than urban sewage treatment. [0003] High-concentration organic wastewater mainly has the following characteristics: First, the concentration of organic matter is high. COD is generally above 2000mg / L, and some even reach tens of thousands or even hundreds of thousands of mg / L. Relatively speaking, BOD is relatively low, and the ratio of BOD to COD in many wastewaters is less than 0.3. Second, t...
