Sulfide purification treatment method for industrial waste gas

Abstract

The invention relates to the technical field of waste gas purification, in particular to an industrial waste gas sulfide purification treatment method, which comprises the steps of domestication, filtration, absorption, decomposition and neutralization. Specifically, a trickling filtration tower comprises a tower body, a circulating pool and a controller; a filler layer is arranged in the tower body, and three packing layers are arranged in the filler layer; due to the fact that biological bacteria making contact with sulfide firstly in filler are difficult to absorb, sulfide components separated from the filler finally cannot meet the absorption amount required by the biological bacteria, and the sulfide purification effect of the biological bacteria on industrial waste gas is affected. Therefore, according to the invention, the packing layers are arranged in the filler layer, by utilizing different thicknesses among the packing layers and the difference of the absorption effect of biological bacteria on the filler on the sulfide, the absorption amount of the biological bacteria in each packing layer on the sulfide is balanced, and then sulfide components in the industrial waste gas are completely split and absorbed, so that the sulfide purification treatment effect of the industrial waste gas is improved.

Description

technical field [0001] The invention relates to the technical field of waste gas purification, in particular to a sulfide purification treatment method for industrial waste gas. Background technique [0002] Sulfur-containing industrial waste gas is a very harmful gas. Some sulfur-containing industrial gases have a great poisonous effect, and can also be combined with water vapor and dust in the atmosphere, which not only affects people's health and daily life, but also the surrounding The environment and facilities have also been affected to varying degrees. Some pollution incidents have also caused various social problems. The current sulfide pollution mainly comes from the flue gas after combustion. Desulfurization treatment of industrial waste gas is the control The key to air pollution; for an introduction to the purification of sulfide in industrial waste gas, please refer to: Li Juanjuan, Research on Purification of Sulfur-Containing Industrial Gas with Bacteria-enhan...

Problems solved by technology

[0004] There are also some technical solutions on the sulfide purification treatment method of industrial waste gas in the prior art. For example, a Chinese patent with the application number 2018103842620 discloses a sulfide purification treatment method of industrial waste gas: firstly, through the water delivery device to the The filter device transports the liquid aqueous solution mixed with the desulfurization solution; at this time, the dust induction device is activated, so that part of the air enters the upper filter chamber through the guide channel, and the other part enters the lower filter chamber through the filter hole and increases the air pressure of the lower filter chamber; The air entering the upper filter chamber collides with the rain curtain, and the large water droplets in the rain curtain absorb the dust in the air and hit the blocking cone surface and the filter hole. Under the action of its own gravity, it falls from the edge of the blocking cone surface to the filter hole. Carrying the remaining dust into the atomized cloud, the dust absorbs the small water droplets in the cloud; the sewage with dust is filtered by the high-density filter into relatively clean liquid water, and is transported to the filter device by the pump to complete Water circulation; the purification treatment and dust collection speed block in this technical solution has excellent filtering effect, and improves the utilization rate of water resources in the filtering process; Control the degree of desulfurization reaction, and it is difficult to ensure that the desulfurization droplets and the sulfide in the industrial waste gas are fully contacted and absorbed
