Due to its unique characteristics, urban sewage treatment systems have complex and variable components, are toxic and harmful, have obvious dynamic loads, and continue to discharge pollutants near residential areas. Moreover, they are often sudden and difficult to capture and collect, which also brings difficulties to governance. In addition to frequent use of deodorants for spraying, our common treatment methods include the following:

High energy active oxygen ion deodorization

The working principle of high-energy ion purification system is to use positive and negative ions to mimic the self purification correction function of nature to achieve the goal of controlling air pollution (odor).

activated carbon adsorption

The deodorization mechanism of activated carbon adsorption mainly relies on the adsorption effect of activated carbon, allowing the odor gas to be adsorbed and removed through the adsorbent filling layer.

Biofilter bed

The principle of biological filter bed deodorization is to collect and humidify gas, and then input it into the bottom of the biological filter bed through a pipeline to disperse it in the soil. Various pollutants in the odor dissolve in water and adsorb on the surface of soil particles.

Biological drip filter tower

The main body of the biological drip filter tower is a filling tower, with one or more layers of packing inside. The outer surface of the packing is a few millimeters thick biofilm composed of microbial communities. The organic waste gas enters the biofilter from the bottom of the tower and is purified by touching the moist biofilm during the ascent process. The purified gas is discharged from the top of the tower.

Biological filter

The biological filter mainly includes two parts: a humidifier and a biological treatment device. The odor collected by the induced draft fan is pretreated by a humidification device (some pre-treatment also includes temperature regulation, particle removal, etc.) before entering the biological treatment device. The pollutants in the gas are dispersed from the gas phase main body to the water film on the outer layer of the packing and adsorbed by the packing, ultimately degrading into carbon dioxide, water, etc. The treated gas is discharged from the top of the biological filter.
