Abstract

The invention relates to a method for treating high-concentration organic industrial waste water and equipment thereof. In the invention, processes of micro-electrolytic reaction, catalytic oxidation reaction, electro-catalytic oxidation reaction and photo-catalytic oxidation reaction are creatively combined organically for pretreatment, and then, biochemical treatment processes of hydrolytic acidification and contact oxidation are matched to ensure that the treated waste water reaches the standard. The equipment of the invention comprises a complex electric bed, a photo-catalytic oxidation device, a hydrolytic acidification pond and a contact oxidation pond which are connected sequentially, wherein a waste water inlet is arranged on the complex electric bed, and a purified water outlet is arranged on the contact oxidation pond. The combined equipment can realize the purpose of converting and decomposing organic matters which can not be degraded easily, high-molecular organic matters and toxic organic matters into organic matters which can be degraded easily, low-molecular organic matters and non-toxic organic matters, thereby achieving the discharge standard finally. In addition, the equipment of the invention can realize integration and control automation, has high degree of automation and low operating cost, and is very suitable for industrial popularization and application.

Description

technical field [0001] The invention relates to a method and equipment for treating industrial wastewater, in particular to a method and equipment for treating high-concentration organic industrial wastewater. Background technique [0002] Since the development of coal tar processing and petrochemical industry, many new industrial organic substances such as plastics, artificial rubber, synthetic fibers, medicines, pesticides, etc. have brought new brilliance to human civilization, but at the same time, the pollution of organic substances to the environment is also increasing. , and pose a serious threat to human health. [0003] Organic matter refers to the general term for carbon-containing compounds (except for a few simple carbon-containing compounds such as carbon monoxide, carbon dioxide, carbonic acid, and carbonate), the vast majority of which are hydrocarbons, and often contain oxygen, nitrogen, halogen, sulfur, and phosphorus. and other elements. At present, the o...
