过氧化氢处理工业废水研究进展(续)

8 处理其他废水 H2O2可处理的其他废水种类繁多，列举于下。广东工业大学徐劲等人研究用Fenton试剂法处理选矿废水中残余的黄原酸盐（黄药），考察了影响降解效果的因素。在选定条件下，黄药去除率可达99．5％。西北工业大学吴耀国等人研究了废水溶液化学组分对O3／H2O2降解TNT的影响，结果表明，HCO3^-、HCOO^-、Cu^2＋对TNT降解有抑制作用；而Al^3＋则有促进作用。另外，

Research Advances in Wastewater Treatments with Hydrogen Peroxide

Recent research advances in wastewater treatments with hydrogen peroxide (H2O2),especially the advances at home are introduced.Treatment methods include Fenton reagent(H2O2 /FeSO4), UV/H2O2, O3 /H2O2, UV/TiO2 /H2O2, activated carbon/H2O2, etc. Pollutants include sulfides,cyanides,phenolics,dyes,pesticides and miscellaneous.The treatment effects are decreasing COD, TOC and colourity values,and improving biodegradability.Treatment of wastewater with H2O2 can be carried out independently to reach the discharge standard.It can be also used as pretreatment or final treatment of other conventional treatments (e.g. biochemical treatment, etc) for reaching the same object.The current general situation and the future prospect of H2O2 application in environmental protections are introducedb riefly.
