The aim of the present study was to assess the effect of advanced oxidation processes (AOPs) (oxidation ozone and peroxide/ozone) on the toxicity of leachates from municipal landfill for Warsaw, Poland, using a battery of tests. AOPs used to pre-treat leachates were carried out in laboratory conditions after their coagulation with the use of FeCl3. The effects of the pre-treatment of leachates using the method of coagulation with FeCl3 depended on the concentration of organic compounds and with optimal conditions of the process ranged from 40 to 70%. Further pre-treatment of the leachates after coagulation, involving the use of oxidation with 03 and H2O2/O3, did not cause significant decrease of leachate toxicity. The data of this study demonstrated the usefulness of the battery of tests using Daphnia magna, Artemia franciscana, Scenedesmus quadricauda and Vibrio fischeri for the toxicity evaluation of raw and pre-treated leachates.
本研究的目的是通过一系列测试，评估高级氧化工艺（AOPs）（臭氧氧化以及过氧化物/臭氧氧化）对波兰华沙城市垃圾渗滤液毒性的影响。用于预处理渗滤液的AOPs是在实验室条件下，在使用FeCl3进行混凝之后进行的。采用FeCl3混凝法预处理渗滤液的效果取决于有机化合物的浓度，在该工艺的最佳条件下，去除率在40%至70%之间。渗滤液在混凝后进一步进行预处理，包括使用O3和H2O2/O3氧化，并未导致渗滤液毒性显著降低。本研究的数据表明，使用大型溞、卤虫、四尾栅藻和费氏弧菌进行的一系列测试，对于评估未处理和预处理渗滤液的毒性是有用的。
