Water micro-bacteria active filler and preparation method thereof

Abstract

The invention discloses an Aquamicrobium defluvii active filler and a preparation method thereof. The Aquamicrobium defluvii SU1 disclosed by the invention is an isolate obtained by treating a reactor containing H2S and other odorants in Water Pollution Control Laboratory in Research Center for Eco-Environmental Sciences of Chinese Academy of Sciences; and the strain is collected in China General Microbiological Culture Collection Center, and the collection number is CGMCC No. 7399. The Aquamicrobium defluvii active filler without sulfur-containing odorants has the advantages of large specific area, high porosity, high air permeability, small resistance, high bacterial cell loading capacity and low loss tendency; the active filler with the Aquamicrobium defluvii SU1 has higher efficiency for degrading hydrogen sulfide; and the Aquamicrobium defluvii active filler also has the advantages of low filling density, low pressure and low tendency to corrosion and deformation in the waste gas purification bioreactor, and can be used for a long time and applicable to complex treatment conditions.

Description

technical field

[0001] The invention belongs to the field of environmental treatment, in particular to an active filler for removing sulfur-containing malodorous substances, a preparation method and application thereof. Background technique

[0002] In the process of sewage, sludge treatment, garbage treatment and composting, a large amount of odorous gas will be produced. Sulfur-containing substances such as hydrogen sulfide, mercaptan, sulfide, and carbon disulfide are common odorous substances in the odorous gas. The malodorous substance escapes into the atmosphere and spreads everywhere with the flow of air, causing pollution to the surrounding environment and causing harm to human health. At present, the control of air pollution and odor has attracted more and more attention, and many countries have established strict emission standards. Strictly control the discharge of pollutants in the exhaust gas, and require enterprises to take corresponding control measures befor...
