One-step vacuum concentration and crystallization equipment

— Technical Value —

(1) The chemical pretreatment section is used as an auxiliary process to reduce the waste gas treatment load of the two-stage biological treatment section and improve the removal efficiency of the waste gas treatment system;

(2) The two-stage biological treatment section adopts our mature biological trickling filtration and biological filter technology, which can effectively ensure the residence time of waste gas in the packed bed and maximize the waste gas treatment effect. The waste gas treatment process is all biochemical reactions, no secondary pollution is generated, and the waste gas is finally oxidized into CO2, H2O, etc.

(3) Our company has an original strain culture technology, optimizes the screening of strains that meet the actual needs, and cultivates corresponding strains according to the exhaust gas components to adsorb and degrade odor-causing substances;

(4) It has the ability to screen, cultivate, and inoculate strains, and has the necessary equipment and facilities for strain isolation, inoculation, preservation, and domestication;

(5) The exhaust emission indicators meet the requirements of VOCs≤120mg/m³, H2S≤0.33kg/h, NH3≤4.9kg/h, and the odor concentration is less than 500 (dimensionless).
