Abstract

Belonging to the technical field of environmental pollution treatment, the invention particularly relates to a hydrogen sulfide gas source collaborated sludge bioleaching reactor, and aims to solve the problems of unstable flora biomass, difficult collection and resource utilization of sewage treatment plant odor and the like in the traditional sludge bioleaching operation process. The sludge bioleaching reactor provided by the invention is equipped with a flora activity stabilizing module, on the one hand, the biomass of dominant thiobacillus is increased, and on the other hand, the flora activity and the capability of resisting reaction environment fluctuation are improved. For collection and resource utilization of sewage treatment plant odor, a gas enricher, a hydrogen sulfide pre-dissolving conversion area and other process links are arranged, and a hydrogen sulfide gas source is used as a nutrient matrix in the sludge bioleaching reaction process. The sludge bioleaching reactor realizes sludge heavy metal treatment, sewage plant odor treatment and replacement of a sludge leaching nutrient medium with hydrogen sulfide at the same time, is novel sludge treatment equipment, alsois novel sewage plant odor treatment equipment, and has good market application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution control, and in particular relates to a hydrogen sulfide gas source synergistic sludge bioleaching reactor. Background technique [0002] Sludge bioleaching technology is an important method to control heavy metal pollution in sludge. It utilizes the biochemical metabolism of the dominant bacteria group of Thiobacillus and some heterotrophic bacteria to transform the heavy metals in the sludge into easily soluble states such as exchange states, and finally dissolve them. remove. It has the advantages of wide applicability, strong heavy metal removal ability, and relatively mild reaction process. [0003] Odor is a major pollutant that has plagued sewage treatment plants for many years, and gases such as hydrogen sulfide are the main components of the odor. When hydrogen sulfide reacts with water, sludge, and oxidants, it can be used as a nutrient by the Thiobacillus dominant bact...
