Modular and standardized design, mass production, effective cost reduction, faster delivery.

Core advantage

technological process

Huashijie biological treatment process is composed of biological trickling filtration and biological filtration. It is also called two-stage biological process. It can treat both soluble and insoluble pollutants. The rear fan is adopted, and the negative pressure inside the device works to reduce the emission of waste gas to the environment as much as possible.

The process flow of two-stage biological waste gas treatment is as follows:

After the waste gas enters the device, the biotrickling section in the device and the spray liquid exchange gas and liquid reversely on the packing surface. Most of the soluble pollutants are transferred from the gas phase to the water phase, and the spray liquid circulates. The pollutants in the water phase are used by the microorganisms attached to the packing surface, and are degraded into harmless substances through microbial life activities.

The insoluble pollutants enter the biofilter section with the waste gas, and are captured by the biofilm attached to the surface of the filler, and are digested as nutrients to further realize the harmless treatment of pollutants. The waste liquid produced by the microbial system can be discharged into the sewage system of the plant or the sewage treatment plant due to the absence of harmful substances and B / C ≥ 0.3.

working principle

The pollution substances in the waste gas components are transformed into carbon dioxide, water, polysaccharides, protein organic substances and microbial cell components, inorganic salts and other low harmful or harmless substances by using the life metabolism activities of microorganisms, so as to realize the effective treatment of the components of waste gas pollutants. The process of the transformation of pollutants in micro objects is shown in the following figure:
