摘要
以FeSO4、FeCl3、(NH4)2Fe(SO4)2作为混凝剂,采用混凝-超声的方法来分析垃圾渗滤液处理前后各种物质(COD、氨氮浓度)的变化情况,从而寻找最佳的运行参数。实验结果表明:FeCl3是最佳混凝剂,其最佳混凝条件是,每500 mL原水需加入10 mL浓度为1 g/L的FeCl3溶液,且溶液的pH为10.7。在此条件下用超声波技术处理该溶液,该技术对垃圾渗滤液中高浓度的NH3-N有很好的处理效果,NH3-N的去除率可达到80%以上,同时对COD、色度也有一定的去除率。
The removal rate of COD, NH3 -N was discussed by a coagulation-supersonic method, in order to seek the best movement parameters and enhance the removal rate of COD, Using FeSO4, FeCl3, （NH4）2Fe（SO4）2 as the coagulation drug. The experimental results show that： FeCl3 was the best coagulation drug, its best coagulation condition was： each 500 mL original water must join the 10 mL FeCl3 solution whose density was 1 g/L and the pH of solution was 10.7. Under the condition, using the supersonic wave process the solution. It has high removing rate of NH3-N, COD, color.
