一、流程选择 我厂铜电解车间排放的废水,成分复杂,除含有铜、酸之外,还有镍、铅、锌以及砷等元素,而且浓度都比较高(表1中原液组成),所采用的流程必须能使多种元素达到排放标准并易于回收,这是其一。第二,铜电解车间排放的废水量较大,每天约250M~3,而生产场地又拥挤,不可能有较大 First, the process of choice I plant copper electrolysis plant emissions of waste water, the composition is complex, in addition to containing copper, acid, there are nickel, lead, zinc and arsenic and other elements, and the concentrations are higher (liquid composition in Table 1) The process used must enable multiple elements to meet emission standards and be easy to recycle, which is one of them. Second, the discharge of copper electrolysis plant wastewater larger, about 250M ~ 3 per day, and the production site is crowded, it is impossible to have a larger
