摘要
针对某金矿含砷铅碱性工业废水,研究了采用重金属捕集剂和聚铁联合除铅和砷。试验结果表明:用聚铁可去除废水中的砷,但聚铁用量较大,且对铅的去除没有作用;同时采用聚铁和重金属捕集剂TMT-18F,可有效去除砷和铅,且在相同除砷效果下,TMT-18F的加入可大大减少聚铁的用量,处理后的废水可达标排放。
Using heavy metal collector（TMT-18F） and industrial wastewater is studied. The results show PFS to removal arsenic and lead ions in alkaline that under studied conditions, arsenic can be removed only by polyferric sulfate（PFS）, but PFS consumption is higher, and PFS can not removal lead. But arsenic and lead can be removed simultaneously with TMT-18F and PFS. Using TMF-18F can also reduce consumption of PFS.
