Reinforcing agent for reinforcing biofilm formation of waste gas biofiltration device and application thereof

Abstract

The invention provides a reinforcing agent for reinforcing biofilm formation of a waste gas biofiltration device. The reinforcing agent is prepared from the following raw materials: acyl homoserine lactone, and the concentration of the acyl homoserine lactone in the reinforcing agent is 3-20 mg / L. By using the biological growth reinforcing agent solution provided by the invention, the starting period of the waste gas biofiltration device can be effectively shortened. Compared with an existing starting mode, according to the reinforcing agent of the waste gas biofiltration device and the using mode of the reinforcing agent, the activated sludge solution is immersed in the biofiltration device, and domestication and inoculation and biofilm formation are completed at the same time; by adding the prepared reinforcing agent solution according to the optimal adding mode, the rapid and efficient degradation of the volatile organic compound can be achieved; the use method is convenient and reasonable, and the membrane formation starting time of the traditional biological filtration device is effectively shortened; and compared with the traditional method, the method substantially promotes the formation of the biofilm, and has good technical advantages.

Description

Technical field [0001] The present invention belongs to the field of environmental governance, and in particular, the inventory of exhaust gas biofiltration means and its application thereof. Background technique [0002] Biological filtration technology Treatment of exhaust gas was used in the 1950s, with good processing effect, simple equipment, less investment, no secondary pollution, widely used in exhaust gas governance in various fields. The basic principle of biofiltration technology is to utilize the biofilm loaded on the surface of the filler to decompose the organic component in the exhaust into carbon dioxide and water and the cellular components. Among them, in the initial period of operation of the biological filtering device, the microorganism forms a biofilm in the surface of the filler, also known as the hanging film process, and is a key link to the efficient treatment of the biofiltration device. [0003] At present, the traditional biological filtration device ...

AI Technical Summary

Problems solved by technology

The above two membrane-hanging methods are based on the natural attachment process of the biofilm on the surface of the filler, and the membrane-hanging time often takes 1-3 months, resulting in slow start-up of the biofiltration device.
