Abstract

The invention belongs to the technical field of environmental pollution control, and specifically relates to a hydrogen sulfide gas source synergistic sludge bioleaching reactor, in order to solve the problem of unstable biomass of bacteria flora and foul odor in sewage treatment plants during the traditional sludge bioleaching operation process Difficult to collect and resource utilization and other issues. The present invention is provided with a stable module for bacterial group activity, which increases the biomass of dominant thiobacteria on the one hand, and improves the activity of the bacterial group and the ability to resist fluctuations in the reaction environment on the other hand; for the collection and resource utilization of odor from sewage treatment plants , the present invention is equipped with gas enrichment device, hydrogen sulfide pre-dissolution conversion zone and other process links, so that the hydrogen sulfide gas source is used as the nutrient matrix in the sludge bioleaching reaction process. The present invention simultaneously realizes sludge heavy metal treatment, sewage plant odor control, and hydrogen sulfide instead of sludge leaching nutrient matrix. It is a new type of sludge treatment equipment and a new type of sewage plant odor control equipment, and has a good market Promote application 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...
