Study on Analytical Pretreatment Technology of Organic Matter in Chemical Water

为了解决高浓度化工废水对环境的污染问题,以典型的多环芳烃类高浓度化工废水为例,多环芳烃类高浓度化工废水在生产过程中容易进入水体,对环境的危害大,高盐有机废水的成分中含有大量可溶性无机盐,对生物处理会产生抑制作用。选用UV-Fenton高级氧化技术,强氧化性能把有机物转化为水、二氧化碳和无机盐,所投加氧化剂也不会产生有害物质,具有很好的应用价值。采用该氧化技术对高盐有机废水进行处理,探讨最佳工艺反应条件和反应机理。

In order to solve the pollution problem of high-concentration chemical waste water to the environment,the typical polycyclic aromatic hydrocarbon high-concentration chemical wastewater is taken as an example,and the high-concentration chemical wastewater of polycyclic aromatic hydrocarbon is easy to enter the water body in the production process,and the harm to the environment is large,The high-salt organic waste water contains a large amount of soluble inorganic salt,which can inhibit the biological treatment.In this paper,the UV-Fenton advanced oxidation technology was used to convert the organic matter into water,carbon dioxide and inorganic salts.The addition of the oxidizing agent does not produce harmful substances,and has good application value.Advanced UV-Fenton oxidation technology was used to treat high-salt organic wastewater,and the optimum reaction conditions of UV-Fenton in the treatment of high-salt organic wastewater were investigated as well as the reaction mechanism.
