Embodiment 1

[0038] A rectangular tank body is used to constitute the treatment system for treating malodorous compounds in dirty air in this embodiment, and the length:width:height of the system is 5:3:2.

[0039] As shown in Figure 1 and Figure 2, the system is a plant-microbial symbiosis system, in which the plant is Cymbidium; the microbial consortium consists of bacteria including lactic acid bacteria, actinomycetes, rhodopseudomonas, fermentative yeast It consists of five kinds of microbes including the Saccharomyces yeast of the genus and the Chrysophyta algae of the algae. The specific function of each microorganism in degrading malodorous compounds is described by the following biochemical reactions:

[0040]

[0041]

[0042]

[0043]

[0044]

[0045] In this balanced ecosystem, lactic acid bacteria and Saccharomyces yeasts perform aerobic degradation of VOCs. Probiotics produced by actinomycetes not only degrade VOCs, but also inhibit pa...

Abstract

A plant-microbe symbiotic system for treating the offensive compounds in foul air is composed of the uliginous plant, the microbial consortium consisting of bacteria, photosynthetic and sexual heterotrophic algae and yeast, and a filled bed. Its treating process includes such steps as introducing said foul air to the bottom of said system, making it flow through said filled bed for degradating it by biochemical reaction, and releasing the treated air from the top of system.

Description

technical field [0001] The present invention relates to a system for treating malodorous compounds in dirty air. In particular, the present invention relates to a system for the biological treatment of malodorous compounds in air streams using a novel plant-microbe symbiosis system. With this system, dirty air carrying a mixture of malodorous compounds, namely volatile organic compounds (VOCs), sulfur-containing compounds, and nitrogen-containing compounds, can be effectively and simultaneously treated. In addition, the invention also provides a method for treating malodorous compounds in dirty air by using the system. Background technique [0002] While the industry is becoming more and more developed, it has also brought a series of environmental pollution problems. Among them, odorous gas pollution is a kind of sensory public hazard, which has become one of the seven major environmental public hazards in the world. With the improvement of people's requirements for envir...
