Abstract

The invention belongs to the field of environmental governance, and particularly relates to application of bioactive fillers containing Pseudomonas monnieri in purifying sulfur-containing waste gases.The Pseudomonas monnieri is specifically Pseudomonas monteilii LW-1 having a preservation number of CGMCC No. 13748; the microactive fillers are prepared by adsorbing a suspension of Pseudomonas mongolidus on fillers, and filling the fillers in a mesh hollow sphere; the fillers are used for treating organic sulfur-containing waste gases generated in a pesticide wastewater storage tank, wherein the gas flow rate is 100-5000 m<3> / h; the residence time 1.0-5.0 min; the temperature is 35-55 DEG C; the total concentration of malathion, parathion and methyl parathion is 20-200 mg / m<3>; the degradation efficiency of malathion, parathion and methyl parathion can reach 90% or higher.

Description

Technical field: [0001] The invention belongs to the field of environmental treatment, and in particular relates to the application of a biologically active filler containing Pseudomonas monteilii LW-1 in removing sulfur-containing waste gas. Background technique: [0002] Wastewater from pesticide production contains a large amount of organosulfur pesticides and organochlorine pesticide intermediates, with complex components, high concentrations, and strong toxicity. Some organosulfur pesticides and organochlorine pesticide products or their intermediates, such as parathion, malathion, methyl parathion, chloral, phosphorus trichloride, etc., are volatile, and most of them are organic Sulfur and organochlorine pesticides have a pungent odor. [0003] Parathion (C 10 h 14 NO 5 PS) is a colorless oily liquid with a solubility in water of 24mg / L (25°C). Slightly soluble in petroleum ether and kerosene, miscible with most organic solvents, has garlic odor. Rapidly hydrolyz...
