Problems solved by technology

However, in order to ensure the stable attachment of microorganisms on the surface of smooth packing and the formation of bacterial film, a complicated and long-time start-up procedure is required, usually more than one month, which seriously hinders the industrial application of bio-trickling filtration technology.

Abstract

The organic waste gas purifying biological trickling filtration system and the fast pellicle preparing process are suitable for purifying low concentration waste gas with insoluble and non-degradable organic matter. The biological trickling filtration system consists of a biological trickling filtration reactor, a liquid circulating device, a waste gas input device, a purified gas circulating device, etc. The present invention adopts the ' inducer-target pollutant' double substrate specific degrading bacteria domesticating mode, and circulating gas-liquid sync domesticating and forced filming start mode to simplify the program of starting the biological trickling filtration system. The biological trickling filtration system has high organic pollutant eliminating capacity, stable technological performance and other advantages, and is suitable for industrial application.

Description

technical field [0001] The invention relates to a biological trickle filtration system for purifying organic waste gas and a method for rapidly preparing bacterial film, and is especially suitable for the purification treatment of low-concentration insoluble and refractory organic waste gas. Background technique [0002] Volatile organic compounds produced in industrial production and home decoration have attracted more and more attention. Absorption, adsorption, oxidative combustion (including catalytic oxidation), condensation and biological methods are commonly used technologies for treating volatile organic compounds and odorous substances in the air. Among them, the biological purification process has attracted more and more attention due to its low energy consumption and environmental friendliness. It is an effective, low-cost and practical new VOCs control technology. Biological purification facilities can be divided into three major treat...
