Abstract

The invention belongs to the technical field of microorganism and discloses a technology for removing hydrogen sulfide pollutants from domestic garbage by utilizing a microbial preparation. The technology comprises the following steps: adding the microbial preparation into 10 times of water in parts by weight and uniformly stirring, thereby acquiring a diluent; paving the garbage in thickness of 50cm; inserting holes in the garbage, wherein the hole diameter is 1-5mm and the hole density is 100-200 pieces / m2; uniformly spraying the diluent according to the volume standard of 3-5kg of diluent per m2 and treating for more than 24 hours. The technology is simple and feasible in process, environment-friendly and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a process for removing hydrogen sulfide pollutants in domestic garbage by using microorganism preparations. Background technique [0002] With the development of economy and the improvement of people's living standards, stench has been paid more and more attention as one of the environmental hazards. In sewage treatment plants, many industries, agricultural production and domestic waste dumps, a large amount of unpleasant exhaust gas will be produced, and the main odor-causing components are sulfur compounds. These substances have a wide range of sources and are extremely toxic, among which hydrogen sulfide is the most common and has the widest impact. [0003] There are many hydrogen sulfide removal methods, which can be simply divided into wet desulfurization, dry desulfurization and biological desulfurization. Wet desulfurization is a method of removing hy...
