【摘要】：20世纪以来,医药行业得到了迅猛发展,极大地提高了人类的健康水平。然而,制药企业在生产过程中所排放的废水给环境带来了不可估量的污染。医药废水所含的物质种类繁多、结构复杂、具有很深的色度和较高浓度,甚至有危害人类或其他生物的毒性物质,其中里面许多有机物难以生化降解,无法达到废水排放标准。处理好这类医药有机废水,是当前环保与经济共同发展大环境下的关键。针对有污染的医药废水,主要采取物化法、化学法、生物法以及这几种方法的协同处理法。其中,铁碳微电解-Fenton法和高铁酸钾氧化法在污水治理方面有很多广泛的实际应用,但不可避免地存在一些缺点。本课题旨在改善此方法,并结合药剂学中泡腾片的优势,制成对污水处理效果优良的泡腾片复合制剂,提高资源利用率。目前关于这种氧化复合制剂的研究未见报道,这也将是制药废水处理领域的一个新方向。论文第一章介绍了目前医药废水的特点、国内外研究现状,分析了各种废水处理方法存在的不足及待深入解决的问题,概括了本课题探索的实验方向、具体步骤及创新点。论文第二章考察了铁碳微电解预处理废水的影响因素,以Chemical Oxygen Demand (COD)去除率为评价指标,探索铁碳比、入水pH、时间、曝气对处理效果的影响,确定了最佳工艺条件。第三章通过研究Fenton氧化法处理经过微电解预处理后的废水,考察了入水pH、H202用量、FeSO4用量、反应时间及曝气对处理效果的影响,得到了最佳工艺条件。同时,将微电解与Fenton法结合,分析二者联合的优势及处理废水的效果。论文第四章研究了高铁酸钾联合Effective Microorganisms(EM菌)处理废水的条件,通过单因素实验,考察了初始pH值、高铁酸钾用量、反应时间、曝气、二次处理、活性炭以及EM菌用量对处理效果的影响,同时考察了高铁酸钾法处理模拟染料废水的效果。第五章通过高铁酸钾泡腾片复合制剂的制备,初步探讨了泡腾片各原料的比例、酸碱的使用种类及制备工艺,通过稳定性、硬度、崩解时限、重量差异、发泡量以及处理污水的效果等指标,评鉴泡腾片的质量。并且得出初步结论：该泡腾片复合制剂符合处理污水的要求,稳定性较强,为进一步探索作出了很大的借鉴作用,在废水处理方面具有一定的市场竞争力和开发前景。
[Abstract]:Since the 20th century, the pharmaceutical industry has developed rapidly and greatly improved the health level of human beings. However, the waste water discharged by pharmaceutical enterprises has brought incalculable pollution to the environment. Pharmaceutical wastewater contains many kinds of substances, complex structure, deep chroma and high concentration, and even has toxic substances harmful to human beings or other organisms, many of which are difficult to biodegrade and can not meet the wastewater discharge standards. It is the key of environmental protection and economic development to treat this kind of organic medicine wastewater well. In view of the polluted pharmaceutical wastewater, physicochemical, chemical, biological and synergistic treatment methods are mainly adopted. Among them, Fe-C micro-electrolysis-Fenton process and potassium ferrate oxidation process have a lot of practical applications in sewage treatment, but inevitably there are some shortcomings. The purpose of this paper is to improve this method and combine the advantage of effervescent tablets in pharmacy to make effervescent tablets compound preparation which has good effect on sewage treatment and improve the utilization ratio of resources. At present, there is no report on the study of this oxidation compound, which will be a new direction in the field of pharmaceutical wastewater treatment. The first chapter introduces the characteristics of pharmaceutical wastewater at present, domestic and international research status, analyzes the shortcomings of various wastewater treatment methods and problems to be solved in depth, summarizes the experimental direction, concrete steps and innovative points of this subject. In the second chapter, the influencing factors of iron and carbon microelectrolysis pretreatment wastewater were investigated. The removal rate of Chemical Oxygen Demand was used as the evaluation index, and the effects of Fe / C ratio, pH of water, time and aeration on the treatment efficiency were explored. The optimum process conditions were determined. In chapter 3, the effects of pH ~ (202) and FeSO _ (4), reaction time and aeration on the treatment of wastewater treated by Fenton oxidation were studied. The optimum process conditions were obtained. At the same time, the combination of microelectrolysis and Fenton process was used to analyze the advantages of the two methods and the effect of wastewater treatment. In chapter 4, the conditions of wastewater treatment by potassium ferrate combined with Effective Microorganisms(EM bacteria were studied. The initial pH value, amount of potassium ferrate, reaction time, aeration, secondary treatment were investigated by single factor experiment. The effect of the amount of activated carbon and EM bacteria on the treatment of simulated dye wastewater was also investigated. In chapter 5, through the preparation of composite preparation of potassium ferrate effervescent tablets, the proportion of raw materials, the use of acid-base and the preparation technology were discussed preliminarily. The stability, hardness, disintegration time, weight difference were analyzed. Foaming quantity and the effect of sewage treatment, evaluation of the quality of effervescent tablets. The preliminary conclusion is that the effervescent tablet compound preparation meets the requirements of wastewater treatment and has strong stability. It can be used as a reference for further exploration and has a certain market competitiveness and development prospect in wastewater treatment.
