在有关领导的热情支持和北京环保局等单他的大力协助下,我局所属的解州潜水电泵厂试验成功“吹脱一逆向冲洗闭路循环镀硬铬工艺”。通过初步生产考核,证明达到了设计的零排放要求,实现了镀铬废水的闭路循环。一、问题的提出和设计方案按潜水泵设计要求,要求电机轴、水泵轴镀一层0.25～0.30毫米的硬
With the enthusiastic support of the leaders and his energetic assistance, such as the Beijing Environmental Protection Bureau, the Xiezhou Submersible Pump Works affiliated to the Bureau successfully tested the “blow-off and reverse flushing process of hard-chrome plating in a closed-circuit cycle.” Through the preliminary production examination, it was proved that the zero discharge requirement of the design was achieved and the closed-circuit circulation of chrome-plated wastewater was realized. First, the issue proposed and design program Submersible pump design requirements, requiring the motor shaft, pump shaft plating a layer of 0.25 ~ 0.30 mm hard
