Description
Technical Field
The invention relates to the technical field of waste gas treatment, in particular to high-concentration waste gas treatment equipment for a sewage treatment pool of a petrochemical plant.
Background

The waste gas pollution intensity that sewage treatment station produced is big, and the exhaust emission is big, the pollution composition is complicated changeable, and the foul component in the waste gas especially easily causes great pollution to surrounding environment, factory environment, and the disturbing citizen phenomenon is difficult to avoid.
Generally, the exhaust gas exists in three forms, namely solid, liquid and gaseous, and more in gaseous form. In recent years, domestic advanced technologies are vigorously developed and actively introduced, and the overall structure of the environmental protection industry is gradually improved. Especially, the treatment technology of waste gas and malodorous gas has more advanced development and wide application. At present, the odor treatment technologies applied at home and abroad mainly include a dry neutralization method, a composite photocatalysis method, an ion deodorization method, an absorption method, an adsorption method, a microbial degradation method, a composite active oxygen method, a micronutrient element decomposition method, a combustion method, a condensation method and the like.
In the case of exhaust gas with complex components and high concentration, a single process or equipment cannot solve the problem. Therefore, learning to absorb and digest various different treatment processes is very important, and for complex petrochemical plant sewage and waste gas and special-grade explosion-proof areas, a treatment mode of technology combination, equipment combination, process combination and resultant force solution is selected in a targeted manner.
