Industrial waste gas treatment process based on microorganisms

Abstract

The invention discloses an industrial waste gas treatment process based on microorganisms, relates to the technical field of waste gas treatment, and solves the problems of high toxicity in waste gas, high influence on the activity of the microorganisms, incomplete treatment and purification and the like in the existing waste gas treatment process by utilizing the microorganisms. The industrial waste gas treatment process based on microorganisms comprises the following steps: step A, pretreating high-temperature waste gas generated in an industrial production process , in the first step, introducing the high-temperature waste gas into an adjusting tank to adjust the pH value of the waste gas; and 2, introducing the adjusted waste gas into a hydrolysis acidification tank to decompose nitrogen-containing substances in the waste gas; and 3, introducing the waste gas into an intermediate precipitation tank to remove solid particles in the waste gas. The waste gas is subjected to multiple treatment, the toxicity and temperature of the waste gas are effectively reduced, purification is performed through microorganisms, and the quality of the purified waste gas is conveniently improved.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a microorganism-based industrial waste gas treatment process. Background technique [0002] With the rapid development of social economy, a large amount of waste gas will be generated in the process of industrial production. Waste gas purification mainly refers to the work of treating industrial waste gas such as dust particles, flue gas smoke, odorous gas, and toxic and harmful gases generated in industrial places; waste gas There are many types of pollutants in the air, their physical and chemical properties are very complex, and their toxicity is also different. Generally, the waste gas contains sulfur dioxide, nitrogen oxides, hydrocarbons, etc., and the industrial waste gas is treated by microorganisms, which has the advantages of simple equipment and low investment. , low operating costs, no secondary pollution and other advantages. [0003] However, the existi...
