Abstract

The invention belongs to the field of environmental governance, and particularly relates to a preparation method of microbial active filler comprising pseudomonas monteilii. The pseudomonas monteiliiis particularly Pseudomonas monteilii LW-1, the accession number is CGMCC No. 13748, the microbial active filler is prepared by adsorbing pseudomonas monteilii bacterial suspension on the filler and filling a net-surface hollow ball with the filler, the filler is used for treating organic-sulfur-containing waste gas generated by the pesticide waste water storage pond, gas flow is 100-5000 m<3> / h,the residence time is 1.0-5.0 min, the temperature is 35-55 DEG C, the total concentrations of malathion, parathion and methyl-parathion are 20-200 mg / m<3>, or the concentration of trichloracetic aldehyde is 5-100 mg / m<3>, the degradation efficiency of the malathion, the parathion and the methyl-parathion can reach 90% or above, and the degradation efficiency of the trichloracetic aldehyde can reach 75% or above.

Description

[0001] Technical field: [0002] The invention belongs to the field of environmental management, and in particular relates to a preparation method of a biologically active filler containing Pseudomonas monteilii LW-1. [0003] Background technique: [0004] 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. [0005] 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 hydrolyzed in alkaline medi...
