Abstract

Relevant problems associated with treatment of industrial wastewater from heavy metal ions are considered. Due to industrial development, the amount of wastewater increases as well as the risks of heavy metals getting into surface and groundwater, accumulating in water bodies and becoming aggressive environmental pollutants, which affect the animal and human organisms. To assess the possibility of extracting metal ions (Cd2+, Zn2+, Co2+, Cu2+) from industrial wastewater and their further treatment, studies were carried out on redistribution of heavy metals in the “wastewater – waste” system using iron-magnesium production waste. Samples of the investigated waste weighing 0.1; 0.2; 0.5; 1; 1.5; 2 g were taken for wastewater volume of 50 ml per each subsample. Contact time varied from 5 to 180 min, waste fraction was 1 mm. The interaction process showed that the waste efficiently removes metal ions (Cd2+, Zn2+, Co2+, Cu2+) from industrial wastewater. The efficiency of removing a pollutant from the solution depends on the weight of the waste subsample, initial concentration of metal ions, and contact time.

铁镁生产废渣处理重金属(Cd2+、Zn2+、Co2+、Cu2+)废水的可行性评价
讨论了重金属离子工业废水处理的相关问题。由于工业的发展,废水的数量增加,重金属进入地表水和地下水,在水体中积累,成为具有侵略性的环境污染物,影响动物和人类的有机体。为了评估从工业废水中提取金属离子(Cd2+、Zn2+、Co2+、Cu2+)及其进一步处理的可能性,利用铁镁生产废水对重金属在“废水-废物”系统中的再分配进行了研究。被调查废物的样本重量为0.1;0.2;0.5;1;1.5;每个子样的废水量为50 ml,取2 g。接触时间为5 ~ 180min,废渣率为1mm。相互作用过程表明,废液能有效去除工业废水中的金属离子(Cd2+、Zn2+、Co2+、Cu2+)。从溶液中去除污染物的效率取决于废物亚样品的重量、金属离子的初始浓度和接触时间。
