摘要
实验产生废水含有Cr^(3+)和Cr^(6+),这类废水对人体及动物体有毒害作用,严重污染环境.本实验研究了将铁氧体法处理重金属元素的方法用于处理实验室含铬废水,经测试选定最佳的实验条件,进行平行实验,得到回收产品铁氧体.经处理后污水中含Cr^(6+)浓度小于0.05 mg/L,达到国家排放要求.
Experimental production of wastewater contain Cr^(3+) and Cr^(6+),such waste poison to human and animal bodies,and seriously pollute the environment.Latest researches in chrome-containing wastewater treatments are reviewed,The ferrite technology was used to treat wastewater containing chromium from laboratory.The optimal conditions of experiment are selected after a series tests,and parallel test was carried out under optimal experimental conditions.Finally,the reclaimed product ferrite is gained.The Cr^(6+) concentration of wastewater which have treated by the two methods less than 0.05mg/L,achieving standard.
