Wastewater treatment and removal of hazardous metals is imperative for the well-being of living things and the environment. Different methods for the removal of hazardous metals have been proposed and practiced with varying success. In this study, dust slag generated by electric arc furnace is utilized for the removal of aluminium, barium and magnesium from industrial effluent. Slag which is a waste generated during the process of steel production is alkaline by nature. It was able to raise the pH of the acidic effluent to 8.7 removing most of the metals and reducing the amount of commercial alkali required to raise the pH to the target pH of 12.5. EAFDS in conjunction with lime removed 98% of Al, 95.8% of Ba and 99.7% of Mg. The method was simple, efficient and cost-effective since it utilizes a material considered hazardous waste for the treatment.

使用EAFDS和石灰去除工业废水中的Al，Ba和Mg

废水处理和有害金属的去除对于生物和环境的健康至关重要。已经提出并实践了用于去除有害金属的不同方法，并取得了不同的成功。在这项研究中，电弧炉产生的粉尘炉渣用于去除工业废水中的铝，钡和镁。钢铁生产过程中产生的废渣是碱性。它能够将酸性流出物的pH值提高到8.7，从而去除了大多数金属，并减少了将pH值提高到12.5的目标pH值所需的商业碱量。EAFDS与石灰一起去除了98％的Al，95.8％的Ba和99.7％的Mg。方法很简单
