摘要
城市污水处理厂的恶臭污染已经引起越来越多的关注。介绍了城市污水处理厂的主要恶臭气体。采用氢氧化钠溶液和酸性氧化剂溶液作吸收剂,恶臭气体氨、硫化氢、甲硫醇通过二级吸收塔被吸收,气体达GB14554-93(二级)标准后排放。
More and more attention has been paid to odor pollution in municipal wastewater treatment plants. The main odors in the municipal wastewater treatment are investigated. NaOH solution and sour oxidant solution arc used as the absorbent to absorb NH3, H2S and CH3SH throught two- level absorbing tower and the waste gases are discharged after reaching the standard GB14554 - 93.
