《生物工程》课程论文咖啡因的污染过程、抗性基因与控制原理研究Research on caffeine of Dynamics Process, Risk Assessment and Key Remediation in Contaminated Sites姓名：达羽涵学号：131410127（东华大学环境科学与工程学院，环卓1301，上海，201620）二零一五年十二月二十日摘要：咖啡因（Caffeine）是从很畅销的茶叶、咖啡果中提炼出来的一种黄嘌呤生物碱化合物，现代医学研究表明咖啡因在生理上有重要作用，是一种中枢神经系统兴奋剂，能促进新陈代谢，影响神经、心脏和肾脏的功能,对人类的健康发挥着积极作用。近年来，咖啡因已在世界许多水域中被检测到，包括北海、地中海等。而美国科学家们的必威体育精装版海洋监测和研究结果表明：人类产生的咖啡因已经开始影响太平洋中的海洋生物。在俄勒冈州的几处太平洋海岸已经检测到高浓度的咖啡因。我国是生产和出口咖啡因的大国，所以我国因咖啡因带来的污染也是不可避免的。在咖啡因生产的过程中，虽然没有废气和废渣的产生，却产生了大量的废水。咖啡因废水是一种高、高盐度、毒性大的废水，处理难度相当大。此外，水洗原母液是咖啡因废水值的主要提供者，由此可见水洗原母是咖啡因废水中主要的难处理废液［1］。关键词：咖啡因咖啡因废水咖啡因污染抗性基因控制原理Abstract: Caffeine (Caffeine) is extracted from the very popular tea, coffee fruit out of a xanthine alkaloid compound, modern medical research showed that caffeine has an important role in the physiology, is a central nervous system stimulant, can promote metabolism, affecting nerves, heart and kidney function, on human health plays an active role.In recent years, caffeine has been detected in many of the worlds waters, including the North Sea, the Mediterranean and the like. US scientists latest marine monitoring and research results showed that: caffeine humans have begun to affect marine life in the Pacific Ocean. Oregons PacificCoast has been detected several high concentrations of caffeine. Our country is a big country of production and export of caffeine, so China due to pollution caused by caffeine is inevitable.In the production process caffeine, although there is no waste gas and waste generated, but generated a lot of waste. Caffeine is a waste water, high salinity, toxic wastewater treatment quite difficult. Also, washing raw liquor is the main provider of caffeine wastewater values, we can see the original mother is washing caffeine wastewater main intractable waste [1].Keywords: Caffeine Caffeine wastewater Caffeine pollution The control-principle of resistance genes1咖啡因污染状况与研究意义1.1咖啡因污染的研究意义与应用前景科学家很早就在城市污水中发现了阿斯匹林和咖啡因，但没有得到足够的重视。直到上个世纪90年代，PPCPs污染才被人们正式提出。［2］美国和欧洲都开始对此类污染进行调查
