Electroplating wastewater treatment equipment Do you know the principle of?

Diluent loosening method

Principle: exhaust the odorous gas through the chimney into the air, or use odorless gas diluent to reduce the concentration of odorous substances to reduce the odor. Scope of application: It is applicable to solve the odor gas with medium and low concentration discharged by institutions. Advantages: low cost, simple machinery and equipment. Defect: easily controlled by meteorological elements, and odor substances still exist.

Water digestion and absorption method

Principle: Apply the characteristic that some substances in the odor are dissolved in water to make the odor components immediately touch the water, and then dissolve the strong electrolyte to reach the purpose of film evaporation. Scope of application: odorous gas from water-soluble and organic pollution sources. Advantages: simple professional skills, convenient application and handling, low cost of machinery and equipment work, resulting in secondary pollution, which needs to be solved. Defect: the clean output power is low, which should be applied in coordination with other professional skills, and the actual effect of solving carbon alcohol, oleic acid, etc. is poor.

Hydrolysis acidification pool type activated sludge method Film evaporation method

Principle: The malodorous substances are loosened into the mixed liquid containing the activated sludge process by the hydrolysis acidification tank method, and the microbial strains that have gone through the floating development can dissolve the malodorous substances in a wide range of applications. Scope of application: By 2013, Japan has used it to defecate the odor of garbage dumps and sewage treatment stations. Advantages: After the activated sludge process has been trained, the removal rate of odor components that do not exceed the limit load can reach above 99.5%. Defect: The application of this method also has certain limits for the tube bundles subject to the compressive strength of hydrolysis acidification pool.

Multi material catalytic reaction professional skills

Principle: The reaction tower is filled with specially made solid filler, and the filler is mixed with multi material metal catalyst. When the odorous gas crosses the filling material layer under the actual effect of the centrifugal fan, it is fully touched on the surface of the solid filling material with the highly efficient liquid phase mixed reducing agent sprayed by the specially made nozzle, which emits fog, and under the actual effect of the catalytic reaction of the multi material metal catalyst, the environmental pollution factors in the odorous gas are fully dissolved. Scope of application: It has a wide scope of application, and is very suitable for solving organic waste gas with high air volume and medium concentration, and has a very good removal rate for hydrophobic environmental pollutants. Advantages: small floor area, low project investment and low operation cost; The application process is convenient, and it is ready to use. Defect: It is resistant to impact load and is not easy to harm the concentration value of air pollutants and temperature change, so it needs to consume a certain amount of drugs.
