Deodorization of garbage stations
INDUSTRY OVERVIEW
垃圾处理中心除臭
A waste disposal centre is a specific place where waste generated from industry, domestic production, health care and so on is centralised for recycling and disposal in order to reduce environmental pollution. There are commonly used methods of waste disposal: sanitary landfill, composting and direct incineration.
SOURCES OF EXHAUST GASES
Solvent extraction
Adsorption
Organisms
Membrane separation
Oxidisation
Incinerators
EXHAUST GAS COMPOSITION
Methane
Ethylene
Ethane
Hydrogen Sulphide
Mercaptan
Ammonia
Methyl mercaptan
Methylamine
Formaldehyde
Acetaldehyde
Trimethylamine
Methyl sulphide
The main sources of odour from waste treatment centres are as follows: the waste itself, waste seepage, waste stockpiling, and waste transport.

TREATMENT CHALLENGES
Difficulty in dealing with pollutants
The decomposition of organic matter in waste treatment centres produces odorous pollutants such as hydrogen sulphide, ammonia and organic sulphides, which are difficult to eliminate completely.
The source of the odour is not easy to identify
The source of odour in a waste treatment centre is not easy to identify and may come from a number of sources, such as waste dumping and disposal, adding to the difficulty of deodorisation.
Complex odour components
The odour from waste treatment centres has a complex composition, including not only common gases such as hydrogen sulphide and ammonia, but may also contain toxic and harmful gases such as methane and benzene, requiring different treatment methods for different components.
Unstable emissions
Odour emissions from waste treatment centres are erratic and are affected by a number of factors such as waste collection, transportation and disposal, making it difficult to achieve stable control.

Eclear Environmental RELATED EQUIPMENT
Circulating adsorption deodorization equipment
Eblue Environmental Protection Adsorption Deodorization Equipment uses special catalytic adsorption materials, which can efficiently adsorb odor molecules in the odor in a short period of time, achieving no odor. The consumables of the adsorption and deodorization equipment can be recycled, with a service life of up to 10 years.
Negative pressure deodorization equipment
Eblue Environmental Protection Negative Pressure Deodorization Equipment has the function of sending ion fresh air and negative pressure exhaust to the outside, using photocatalysis and ion technology to remove odor. The negative pressure deodorization equipment sends fresh air to the garbage station and centrally purifies the odor from the garbage station. The negative pressure fresh air deodorization equipment adopts Yilan coupled ion catalytic module and air empowerment module, which plays a role in replacing negative pressure fresh air and removing odor, thereby improving the environment.
Photocatalytic deodorization equipment
Eblue Environmental Protection Photocatalytic Deodorization Equipment is equipped with photocatalytic technology to remove odors, while also providing negative pressure exhaust to the outside. Photocatalytic deodorization equipment can prevent the leakage of odor inside the garbage station and also achieve the deodorization effect of the garbage station. The photocatalytic deodorization equipment adopts a coupled ion catalytic module and an air empowerment module, which plays a negative pressure fresh air replacement and removes odor, thereby improving the environment.
Ionic deodorization equipment
Yilan Environmental Ionic Deodorization Equipment uses active oxygen ions to effectively decompose odor molecules, quickly remove odors, and quickly eliminate bacteria and viruses in indoor air. Ionic deodorization equipment with consumable free technology reduces operating costs and eliminates secondary pollution. The plasma deodorization equipment adopts Yilan coupled ion catalytic module and air empowerment module, which plays a negative pressure fresh air replacement and removes odor, thereby improving the environment.
Spray deodorization equipment
Eblue environmental protection spray deodorization equipment uses spray scented liquid to mask the odor, and the function of negative pressure exhaust to the outside, which is easy to operate and fully automatic control. The installation period of spray deodorization equipment is short, and there is no need to add civil works or change the original facilities.
