基因工程在环境工程中的应用林立 65摘要: 环境工程的核心是环境污染源的治理，其中包含三大方面:固体废物处理，废水处理和废气处理。依靠传统的化学或物理方法对环境中的污染物进行净化，十分耗费人力财力，而且容易造成二次污染。假如利用基因工程技术， 将有降解某种污染物的外源性目的 DNA 片段在体外连接到载体 DNA 之中， 进行基因重组并转移到适当的受体细胞之中, 就可在污染治理中发挥重要的功能。定向构建的超级工程菌则可用于固体废物堆埋场、污水处理厂、油库、地下输送管路以及海洋运输油轮的事故泄露对土壤、地下水以及海岸的污染修复等领域。现在这种技术已经在危险性化合物的技术降解已经得到应用。[1］[2］［3］［4]关键词:基因工程；环境工程;污染处理；综述Genetic engineering application in environmental engineeringAbstract:Environmental engineering is the core of the management of environmental pollution，which contains three aspects:solid waste treatment,wastewater treatment and waste gas treatment 。 Rely on the traditional chemical or physical methods,purifies the environment pollutants in very human cost money,and easy to cause secondary pollution 。 Using gene engineering technique ， a DNA fragment of foreign aim gene that satisfies human demands can be linked to carrier DNA,and then the gene recombinat ion takes place。After that,they will be transferred to suitable cell of acceptor so that they can play an important role in the pollution prevent ion and control.Gene engineering has already been used to degrade dangerous compounds.The structured directionally supper engineering germs can be applied to pollution restoration of soil,groundwater and seacoast result ing from solid wastes landfill and store fields ， sewage treatment plant ， oil depot,underground transport pipes and maritime oil tanker disasters.Key words：Genetic engineering；Environmental engineering；Pollution treatment；review1、基因工程在固体废物处理中的应用。1.1 对...
