纺织印染废水处理中的异味气体控制工程实例

Engineering example for controlling odor gas from dyeing wastewater treatment

对废水处理站产生的异味气体进行收集后,经"净化塔+一级除臭吸附塔+二级除臭吸附塔"系统处理,主要污染气体硫化氢、氨气、臭气去除率分别为76%、79%、45%,排放浓度在《恶臭污染物排放标准》范围内,其他污染物二氧化硫、氮氧化物、颗粒物也在其对应排放标准范围内,满足现有排放标准要求。

Odous gas, generated by the wastewater treatment station, is collected and treated. Atter the systematic treatment of purification tower, first deodorization adsorption tower and second deodorization adsorption tower, the removal rate of hydrogen sulfide, ammonia and odor can reach 76%, 79% and 76% respectively. The emission concentration is within the range of emission standards for odous pollutants. And the contents of sulfur dioxide, nitrogen oxides and particulates pollutants can also meet the emission standards.
