摘　　要：主要研究液态三氯化铁在含砷废水中的使用情况,考察用它替代硫酸亚铁除砷对整个水处理系统的影响,并确定新工艺的最佳操作条件为二段铁砷比在2.0,最佳pH在8~9;三段铁砷比在10,pH在8~10。并对新、旧工艺进行成本核算,为改进现有的除砷工艺提供依据。The application of liquid FeCl3 instead of FeSO4 in As-containing wastewater and the influence on the wastewater treatment system were studied.At the same time,the optimal operating conditions of the new technology were determined that m（Fe）/m（As） at the second operation was 2 and pH 8~9 while the ratio was 10 and pH 8~10 at the third operation which will provide the basis of the new process.
