摘要
针对石灰中和法处理南丹县吉朗铟业有限公司锌冶炼过程中高酸含砷废水,存在污泥量大、污泥处理困难、有价金属流失严重、成本高等缺点,研究采用氧化-控pH中和法处理锌冶炼过程中高酸含砷废水技术。多次试验表明,该工艺简单,技术成熟可靠,具有较好的推广应用的条件。
The novel treatment and recycle technology for waste-water with high acidity and As content from Nandanxian Jilang Zinc Co.Ltd.,oxidation-pH control neutralization process,is investigated in order for solving the problems such as high output quantity of sludge and difficult to disposal,a large loss of valuable metal,high operation costs,etc.It is shown by many times experiments that the new technology is convenient for operation and reliable for indexes.It can be disseminated and applied to similar extracti...
