The soil salification is a serious problem for agriculture and environment . especially now with the development of industry , the situation of soil salification becomes more and more serious , and the quality of water is continuous worsened . research on the mechanism of salt tolerance especially in the important crops , such as wheat , is becoming more urgent than ever before 土壤盐渍化是影响农业生产和生态环境的严重问题，随着工业污染加剧，灌溉用水的质量不断下降和化肥使用不当等原因，次生盐碱化土壤面积有不断加剧的趋势，给农业生产造成重大损失；黄矮病毒病是小麦等禾本科植物的重要病害之一，其传毒介体蚜虫更使植物产量损失巨大。
Guided by the theory of circular economy , the paper adopts the strategy of greening enterprise to research into the measures to help those heavily polluted cities like chongqing and industries in developing countries . the measures include developing circular economy and greening the enterprises . the paper also establishes a module of fuzzy assessment which can help the enterprises continue improving 论文在循环经济的指导思想下，运用绿色企业理论来探讨像重庆一样工业污染严重的发展中国家的城市和工业企业的出路-发展循环经济，走绿色企业之路，并建立企业绿色化的模糊评判模型，以帮助企业持续改进。
Biosorption is a process that utilizes inexpensive active / dead biomass to sequester heavy metals and is particularly useful for the removal of contaminants from industrial effluents . compared with conventional methods such as ion exchange and precipitation with lime , the biosorption process offers the advantages of low operating cost , minimization of the volume of chemical and biological sludge to be disposed of , high efficiency in detoxifying very dilute effluents 生物吸附技术是环境领域近年来迅速发展起来的处理工业污染废水的新技术，它以各种生物(菌类或藻类)吸附废水中的重金属离子，具有吸附容量大，选择性强，效率高，消耗少，并能有效的处理含低浓度重金属离子废水等优点。
Incessant nuclear tests , unlimited industrial pollution so that mankind can continue to enjoy and be lazy , have worsen the condition of the dying earth . yet we are still patting ourselves in the back for coming up with silly inventions like flush - free toilets . we click our tongues in wonder at mutant fishes , but they could not awaken us to our ruthlessness and indifference towards the natural environment 不断的核试炸,无止尽的工业污染,为了满足人类的享受和惰性发展,奄奄一息的地球不断病情加剧,人类却还在为研究出上厕所不必抽水的无聊“发明”而沾沾自喜海洋中畸形鱼的出现只是让人咄咄称奇,却仍不足以唤醒人类对自然生态的无情和冷漠,当然也无法遏止人类对所谓文明科技的需索无度。
However , various historical matters lead to the problems such as unreasonable structure and distribution of industries , heavy industrial pollution , obvious structural conflict among high investment , high consumption and heavy pollution , poor benefit , lack of competitive power in technology and production 重庆作为我国第4个直辖市，六大老工业基地之一，工业门类比较齐全，但由于各种历史原因，工业结构、布局不甚合理，工业污染严重。高投入、高消耗、高污染结构性矛盾突出，经济效益低下，技术、产品竞争力弱，相当?部分工业企业面临的形势非常严峻。
Fortunately , many friends of the earth concerned about the environment and society have been striving diligently for the cause of conservation over the years . they have formed alliances to tackle various issues including industrial pollution , animal protection , excessive use of chemicals in farming , destruction of natural habitats , garbage disposal , nuclear safety , water pollution , and air pollution 幸而多年来有许多关心环境与社会的朋友不断为此奋斗，他们针对不同的议题相互结盟，例如：工业污染动物权益农药过量栖地破坏垃圾处理核电安全水污染空气品质等。
