The main components of the odor from hospital sewage stations are odorous organic gases such as hydrogen sulfide, ammonia, methyl mercaptan, and methyl sulfide. Currently, the main methods for treating odorous organic gases include activated carbon adsorption, low-temperature plasma, biological, and UV photolysis.

（1）活性炭吸附法

Activated carbon adsorption method is a common waste gas treatment method. The adsorption method utilizes porous activated carbon, silica gel, anthracite, etc. to adsorb organic gas molecules onto their surfaces, thereby purifying exhaust gas.

Advantages: High purification rate (activated carbon adsorption can reach over 95%), practical applicability, simple operation, and low investment.

(2) Plasma purification method

During the process of dielectric barrier discharge in plasma purification equipment, particles rich in high chemical activity are generated inside the plasma, such as electrons, ions, free radicals, and excited state molecules. The pollutants in the exhaust gas react with these high-energy active groups and are converted into substances such as CO2 and H2O, thereby achieving the goal of purifying the exhaust gas.

Applicable conditions: Wide applicability, high purification efficiency, especially suitable for multi-component odorous gases that are difficult to treat by other methods. Electrons have high energy and can interact with almost all odorous gas molecules.

(3) Biological Law

Biological deodorization is a biological waste gas treatment technology that uses microbial membranes specially cultivated on biological fillers in biological filters to deodorize waste odor molecules. Biological deodorization mainly utilizes microbial deodorization to transform odorous substances through physiological metabolism of microorganisms, effectively decomposing and removing target pollutants to achieve the goal of odor control. When toxic, harmful, and foul smelling exhaust gases containing a mixture of gas, liquid, and solid are collected through pipelines and introduced into this system, they are purified and degraded by biofilm formed by efficient microbial strains grown on biological fillers.

(4) UV photolysis method

Using UV photolysis purification equipment to emit a specially designed high-energy UV beam to irradiate odorous gases, the molecular chain structures of H2S, sulfides, VOCs, benzene, toluene, and xylene are cracked, and the molecular chains of organic or inorganic high molecular weight odorous compounds are degraded and transformed into low molecular weight compounds such as CO2 and H2O under high-energy UV beam irradiation. By using high-energy UV beams to break down the molecular bonds of bacteria in odorous gases, the nucleic acid (DNA) of bacteria is destroyed, and then oxidized by ozone to achieve deodorization and kill bacteria.

Advantages: Efficient odor removal, with a deodorization efficiency of over 95%; Strong adaptability, suitable for deodorization and purification of low to medium concentrations, atmospheric quantities, and different odorous gases; The product has stable performance and reliable operation, and can work continuously 24 hours a day; Low operating costs, low energy consumption of equipment, no need for dedicated management and maintenance, only regular inspections are required.
