Abstract

The invention discloses a foul gas purifying tower, wherein a gas discharge pipe is arranged at the top of a tower body, a spray liquid collection tank, a gas distribution pipe, a biological stuffing deodorant layer and a physical absorption layer are arranged in the tower body from bottom to top; loofah sponge loaded with a biological membrane is arranged in the biological stuffing deodorant layer; the stuffing in the physical absorption layer is coconut fibre. The foul gas purifying tower disclosed by the invention creatively adopts biological stuffing deodorant layer with the loofah sponge loaded with the biological membrane to coordinate with the physical absorption layer taking the coconut fibre as stuffing for odor treatment, raw materials are easily obtained and the cost is low, the purification efficiency is high, and the purification efficiency on foul gas can reach 90 percent or above; the usage is safe, no secondary pollution is produced; the size of the purifying tower is small, stuffing changing is convenient, no chemical substance is needed to be added during treatment, so investment and operating cost of equipment are low, and an economical and effective processing method for foul gas processing is provided.

Description

technical field [0001] The invention relates to the field of environmental treatment, in particular to a malodorous gas purification tower. Background technique [0002] All gases that stimulate the olfactory organs to cause people's unpleasantness and damage the living environment are odorous pollutants. The main components of malodorous gas include hydrogen sulfide (H 2 S), ammonia, trimethylamine, carbon disulfide, styrene, tetramercaptans, etc., the smell is unpleasant to the senses, and will endanger the physiological health of the human body, such as dyspnea, nausea, chest tightness, vomiting, etc. [0003] With the rapid development of the national economy, people are paying more and more attention to the quality of the living environment. In order to control the impact of odorous gases on the environment, the National Environmental Protection Agency promulgated the "People's Republic of China Emission Standards for Odor Pollutants" ( GB14554-93), this standard stip...
