摘　　要：文章对某农药厂废气中硫化氢及废水中的硫化物的监测及处理技术进行了研究.对废气中硫化氢,采用亚甲基蓝分光光度法,现场采样、现场测定.而对废水中硫化物,则先采用酸化、氢气吹取、吸收的方法预处理,然后再测定其含量.在废水的处理中,选用了PAM、明矾、过硫酸铵配成复合水处理剂,取得了良好的效果.Testing and handling H2S and sulphide in waste gas and water is studied with the sample from a pesticide plant. Using submethyl blue spectrum analysis, spot sampling and testing are conducted. In the determination of sulphide in wastewater, the pretreatment of acidizationextractionabsorption is made first, and then the content is tested. In wastewater's disposal process, ideal compound water disposal agent is made by mixing PAM, alum and ammonium supersulphate.
