Problems solved by technology

Microbial methods have the ability to remove most organic pollutants such as petroleum hydrocarbons, and can effectively reduce the content and toxicity of pollutants in water bodies. However, microbial methods are difficult to treat organic pollutants with poor biodegradability, and are often suitable for low pollution loads. Water body remediation has a relatively strong dependence on environmental conditions, and the effect of remediation treatment is often restricted by factors such as salinity, electron acceptor / donor content, etc., especially when the wastewater has high salinity or salinity fluctuations are large, It will lead to the death of microorganisms and the disintegration of bacterial gelatin groups, which will seriously affect the growth and normal operation of microorganisms, and the treatment effect of microbial methods will be greatly reduced

Embodiment Construction

[0010] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments.

[0011] A sewage treatment method comprises the following steps: introducing ozone micro-nano bubbles into the sewage and arranging activated carbon ceramic composite materials loaded with catalysts in the sewage.

[0012] The ozone micro-nano bubbles are formed by ozone passing through the micro-nano ceramic membrane.

[0013] The pore size of the micro-nano ceramic membrane is 30nm-5μm.

[0014] The catalyst is a rare earth oxide, Cu 2+ , Fe 2+ , Fe 3+ 、Al 3+ 、K + at least one of the

[0015] The present invention purifies sewage through ozone micro-nano bubbles, and at the same time decomposes organic matter rapidly through micro-electrolysis formed by catalysts (metal ions) and carbon to achieve the purpose of fading and reducing COD. Through the above two measures, the effect of sewage p...

Abstract

The invention discloses a wastewater treatment method including steps of: feeding micron / nano ozone bubbles into wastewater and arranging an active carbon / ceramic composite material supporting a catalyst in the wastewater. The method can quickly decompose organic substances in water and has functions of decoloration and reduction of COD. The method has good wastewater treatment effect.

Description

technical field [0001] The invention relates to a sewage treatment method. Background technique [0002] At present, with the rapid development of economy and society, the pollution of surface water in my country is worrying. There is a certain degree of pollution in the water bodies of the seven major river basins in the country. A large amount of industrial and domestic sewage is produced in cities and towns, which seriously endangers the safety of drinking water, especially petrochemical and paper-making pesticides. Such industrial enterprises produce a large amount of organic pollutants, seriously affecting economic and social development, so environmental issues have gradually received widespread attention from the society. [0003] Microbial method is currently the most widely used method for organically polluted wastewater treatment. By selecting microorganisms that exist in nature or artificially domesticated, the biodegradation of organic pollutants is carried out un...
