Description
Technical field
The present invention relates to a kind of liquid for treating waste gas, particularly a kind of benzene series discharging waste gas treatment fluid applying hydroxyethyl carboxymethyl cellulose.
The invention still further relates to the preparation method of above-mentioned treatment fluid.
Background technology
Toluene, dimethylbenzene, benzene, be industrially commonly called as " triphen ", is widely used in fuel, agricultural chemicals, production of flavor, makes paint, pharmacy, the industries such as Furniture manufacture as industrial chemicals or solvent.In recent years along with the development of electronics industry, machinery, automobile making, printing, shoemaking, coatings industry, application toluene, benzene etc. get more and more as the occasion of solvent, thus cause and volatilize a large amount of gas benzene in air.Therefore waste gas containing benzene is also day by day serious for the pollution of air.They are poisonous organic compound, and leukaemia is the modal malignant tumour relevant with benzene poisoning, and toluene poisoning main manifestations is the impression to nervous centralis, and dimethylbenzene toxicity major effect renal function, embryo or reproductive system.
Processing method for " triphen " generally have combustion method, active carbon adsorption,
Combustion method not easily processes large quantity of exhaust gas, and complicated operation has certain danger.After active carbon adsorption adsorbs certain waste gas, adsorption capacity can decline, and needs the activated carbon that more renews or to its regeneration process, be therefore only applicable to the waste gas that low concentration, tolerance are little, and continuation is not high, easy secondary pollution.
