Core Technology

Cover deodorization technology

The cover deodorization technology is mainly applied to the deodorization of exposed buildings, facilities and equipment that generate odors, and is a key factor affecting the quality of odor control in sewage treatment plants. By installing a cover plate, the odor is effectively blocked from spreading, and then collected by the air duct to the odor treatment system. After a series of chemical and biological treatments, it meets the emission standards.

Biological filter deodorization technology

Biological methodIn terms of odor control, it has obvious advantages, high degree of electrification, and simple operation, and has become the mainstream method for treating odors in China.

Basic principlesIt utilizes the biochemical reactions of microorganisms to oxidize and degrade pollutants, transforming them into harmless or minimally harmful substances.

Biological filter methodIt is an air pollution control technology that has been researched earlier and has relatively mature technology. It has the advantages of avoiding or reducing secondary pollution, low investment, low energy consumption, low operating costs, and simple equipment. Its deodorization efficiency is greater than 90%, and it has a good effect on large amounts of odor, which is favored by many large municipal and chemical wastewater units.

Processing technologyPre washing+biological filter

Biological drip filtration deodorization technology

biotrickling filterIt is a biological deodorization technology that combines biological filters and biological washing tanks. The structure of the biological drip filter is similar to that of the biological filter, with the difference being the packing and circulating liquid. When the moist exhaust gas passes through the packing layer with biofilm attached, the odorous substances in the gas dissolve in water and are adsorbed and absorbed by the circulating liquid and microorganisms attached to the surface of the packing, achieving the purpose of purifying the gas.

Advantages of biological drip filtration methodWith a wide processing range, efficient and reasonable equipment, and a small footprint, it has become one of the mainstream microbial deodorization technologies at present.

Chemical washing technology

Chemical washing technologyIt is the use of gas-liquid mass transfer theory that during the process of exhaust gas passing through the scrubbing tower, VOCs/odorous (acidic/alkaline) pollutants undergo irreversible chemical reactions with the absorption liquid to achieve purification purposes.

Vertical absorption towers are usually chosen as absorption equipment, which have the advantages of uniform water distribution, fewer internal components, low operating resistance, large contact area, and good gas-liquid mass transfer effect.

Composition of chemical washing tower device:

The chemical absorption device consists of a shell, a bracket, a circulating spray device, packing, a circulating water pump, an automatic dosing device, etc.

Low temperature plasma technology

The pollutants in the exhaust gas react with plasma active groups and are converted into CO2 and H2O. It can interact with almost all odorous gas molecules, especially suitable for multi-component odorous gases that are difficult to treat.

UV photocatalytic deodorization technology

Degradation of organic or inorganic high molecular weight odorous compounds into CO2 and H2O using UV ultraviolet beams. Equipment composition: pre filter screen+UV lamp tube+special catalyst.

Activated carbon adsorption deodorization technology

Using activated carbon to adsorb odorous substances in the odor, achieving the purpose of deodorization. Suitable for organic waste gases with high air volume, low concentration, low humidity, and low dust content.

Plant extract spray technology

Plant extract spray technologyIt is a deodorization technology for plant liquid spraying system composed of control system, plant liquid supply system, atomization system, and related pipelines, accessories, etc.

Plant liquid utilizes active functional groups in plant extracts, such as alkaloids and terpenes, to atomize and form surface energy. This surface energy can adsorb odor molecules and undergo decomposition, polymerization, substitution, substitution, addition, and oxidation reactions with them, promoting the change of odor molecules' original molecular structure and deodorization.
