【摘要】 为了防止环境污染,我们对印刷厂的水质进行了分析,制定了处理含Cu和FeCl₃废水的方案。经过大量实验,获取了有效数据,处理后的废水已达到了国家排放标准。结果证明实验是成功的,方案合理可行。并据此为制版厂设计了一套处理FeCl₃废水的方案。更多还原

【Abstract】 We analyse the water quality in printing factory, work out a plan treating waste water containing FeCl₃ to prevent environment pollution. Effective data are abtained through many experiments according to the plan. Treated waste water quality achieves the national draining standard. The result shows that the experiment is successful, the plan is practical. We also design a plan treating waste water containing FeCl₃ for platemaker.更多还原
