针对目前太湖地区日益提高的电镀废水排放标准,提出采用混凝-微滤膜过滤组合工艺来去除电镀废水中的铜和镍。从工程应用的角度出发,研究并探讨FeSO4混凝-微滤膜法去除电镀废水中铜、镍时的影响因素,并确定其最佳运行参数,考察该组合工艺的实用性。所取电镀废水中Cu2+质量浓度为57.6 mg/L,Ni2+质量浓度为42.0 mg/L,采用FeSO4混凝剂及PVDF微滤膜处理后,出水中Cu2+和Ni2+质量浓度为0.15、0.87 mg/L,低于国家《污水综合排放标准》一级排放标准要求,同时具有较强的经济适用性。

奶形触头是SN10系列断路器的主要零部件,为了保证导电性能和良好的电接触,一般表面复盖采用镀银,但该零件在镀银过程中却常有“针孔”出现:即在镀层上有些微小的凹孔或点状穴。针孔影响银层与基体的结合力,影响外观质量和其表面粗糙度。为了防止、消除针孔,提队镀银质量 ...
