摘要：随着水资源的日益紧缺，现代工业的迅速发展和城市人口的增加，生活用水和工业用水急剧增加，用各种方法将污水中所含的污染物分离出来或将其转化为无害物，从而使污水得到净化尤为重要。本实验论文对制药污水的各种处理方法进行了理论分析、应用研究，对其各自的特点特性进行了对比分析。着重运用助凝混凝法和铁碳微电解的两种方法对制药废水中的COD进行实验研究分析。在实验中使用了这两种方法对制药废水进行处理，结果表明：在铁碳微电解实验处理制药废水中，通过调节PH值与反应时间等不同条件下，选择最佳处理条件，最终COD去除率达到90%以上，这表明了电解法在制药废水处理中的可行性，但反应时间过长；利用助凝混凝剂处理制药废水中，通过调节不同比例和PH值等条件，但处理效果仍然不理想，仅达到了44.56%去除率，废水中仍然还有大量的COD。5705

A study of a wastewater treatment process
Abstract: With the increasing scarcity of water resources, the rapid development of modern industry and the city population increases, domestic and industrial water use increased dramatically, with the various methods of pollutants contained in the wastewater separation or convert it into harmless substance, so that the purified sewage is particularly important.In this study, the pharmaceutical wastewater treatment methods for a variety of theoretical analysis, applied research, the characteristics of their respective characteristics were analyzed.Focuses on the use of coagulant coagulation and iron-carbon micro electrolysis are two methods for the pharmaceutical wastewater COD experimental research and analysis.In experiments using these two methods in the pharmaceutical wastewater treatment, the results showed that:in the iron-carbon micro-electrolysis treatment of pharmaceutical wastewater by adjusting the PH value of reaction time and under different conditions, to choose the best treatment conditions, the final COD removal rate reached 90%, which indicates the electrolysis in the pharmaceutical wastewater treatment feasible , but the reaction time is too long;coagulant coagulant use in pharmaceutical wastewater treatment by adjusting different proportions, and PH value conditions, but the treatment effect is still not ideal, only reached 44.56% removal efficiency, there is still a lot of wastewater COD.
Keywords:pharmaceuticals; wastewater; micro-electrolysis; coagulant coagulation; experiment.
