The application of ecological concepts to the industrial setting has been touched upon by literature across several disciplines. Two emerging ecological planning approaches, landscape ecology and industrial ecology, are applied here to look at alternative ways of planning industrial parks. As an emerging field, landscape ecology provides different viewpoints from the traditional approach of natural conservation, which mainly focuses on the protection of nature. The approach of landscape ecology regards the environment as a land mosaic, a mixture of natural and urban environment, which concerns a manageable human-scale environment across one or two human generations. Industrial ecology, on the other hand, goes beyond the traditional “end of pipe” idea of pollution control and learns from the ecosystem concept. The current paper is an attempt to reconcile these two fields as an integrated approach to the planning of industrial areas. Using a case study of Singapore’s Jurong Island industrial park, two fundamental issues behind the idea of landscape ecology and industrial ecology are raised. If raw materials, energy and by-products are more easily replaced or reused by technology and management, then research on industrial ecology and related knowledge will be crucial for developing natural resource substitution by innovative technology and new ways of environmental management. Where it is difficult to substitute natural resources, the skills of planning and managing natural resources will take priority over other strategies. In this situation, the knowledge of landscape ecology needs to be applied to the prediction, design and evaluation of ecologically optimum resource uses, patterns and processes in the mixture of natural, urban and industrial environment. A new concept, “nurtured landscape”, is proposed for mediating between the natural ecosystem and the urban/industrial environment. The nurtured landscape provides a basis for the development of new ecological technology using landscape to ameliorate the polluting effects of the urban/industrial neighbourhood. The planning of Singapore’s Jurong Island industrial park provides a test of applying the principles of landscape ecology and industrial ecology to the possible transformation of an industrial area. 相似文献

Over the past few years, the eco-industrial park (EIP) concept has been emerging as a significant driving force for sustainable industrialisation. Accumulating evidence indicates that the transition of existing industries into eco-industrial networking through industrial ecology (IE) principles would provide an excellent opportunity for facilitating such innovative industrialisation. A SWOT analysis was carried out to identify the potential and constraints for the successful implementation of an eco-industrial park in the ecologically fragile coastal zone of Puducherry. The results indicated significant potential for EIP development with few challenges. The lessons learnt can be used to provide broad guidelines for facilitating EIP development in the Puducherry region and similar scenarios found elsewhere across the world, especially in developing countries. 相似文献

本研究开展了印染废水臭氧氧化影响因素、降解动力学和淬灭实验,测定了自由基物种、降解产物和琥珀酸脱氢酶活性.结果表明,苯胺去除效率随着pH值、臭氧投加量和臭氧投加速率的增加分别逐渐减小、增加和减小,且臭氧浓度为24 mg·L-1时苯胺去除效率最高.臭氧氧化苯胺的适宜条件为:臭氧浓度为24 mg·L-1、臭氧投加量为200 mg·L-1和臭氧投加速率为4 mg·min-1,此时苯胺的去除效率为47.2%.臭氧氧化苯胺是直接氧化为主结合羟基自由基反应的作用过程.苯胺脱氨基和裂解苯环后生成戊二酸或L-焦谷氨酸直至矿化.大肠杆菌在原水和臭氧氧化后废水中的酶抑制率分别为83.4%和24.7%.臭氧氧化前处理后,混凝去除色度、SS、COD、总氮、总磷、硫化物和苯胺的效能分别提高了0.72%、0.46%、31.40%、9.40%、22.80%、31.40%和63.30%.研究结果为臭氧氧化印染工业园废水前处理的应用提供了基础依据. 相似文献

工业园区TVOC和恶臭的电子鼻检测技术研究 总被引:6,自引:3,他引:3
根据工业园区中TVOC和恶臭可能存在的主要气体组分,筛选传感器阵列,构建用于检测工业园区内TVOC和恶臭的电子鼻系统.本研究设计了TVOC污染指数(TPI)和恶臭污染指数(OPI)及基于电子鼻的现场检测方法.在此基础上,结合嘉兴市乍浦港区内化工园区污染情况分析,选择6个检测点进行现场检测,各传感器响应值经PCA分析,提取了2个主成分即可将8个传感器分为2类:TVOC型(S1)和恶臭型(S2~S8).将现场采集的气体样品用GC/MS进行定性分析,各采样点TVOC物质积分面积百分比在10%以上的累积起来大多都占总面积的90%以上,而恶臭类物质则大多都在10%以下.结果表明:①选用合适的传感器阵列,结合PCA分析,可以初步反映工业园区内TVOC和恶臭的污染情况;②结合电子鼻测得的污染指数与GC/MS定性分析结果,可以大体得出工业园区TVOC和恶臭总体污染情况及各种污染物分布情况;③电子鼻和GIS技术综合应用到工业园区TVOC和恶臭的检测,能初步用于评估工业园区空间污染情况. 相似文献

Nowadays, more people tend to spend their recreational time in large national parks, and trace metal(loid)s in soils have attracted long-term attention due to their possible harm to human health. To investigate the pollution levels, potential sources and health risks of trace metal(loid)s in road soils, a total of eight trace metal(loid)s (including As, Cd, Cr, Cu, Ni, Pb, Zn and Hg) from 47 soil samples along roads were studied in the Huangshan National Park in Southeast China. The results showed that the concentrations of As, Cd, Pb, Zn and Hg appeared different degrees of pollution compared with their corresponding background values. According to the pollution indices, Hg and Cd were recognized as significant pollutants presenting moderate to high ecological risk. Combining principal component analysis and positive matrix factorization model, the results showed that traffic, industrial, agricultural and natural sources were the potential origins of trace metal(loid)s in this area, with contribution rates of 39.93%, 25.92%, 10.53% and 23.62%, respectively. Non-carcinogenic risks were all negligible, while the carcinogenic risk of As was higher than the limit (1 10−6). Moreover, children were more susceptible to trace metal(loid)s by ingestion which appeared to be a more important exposure pathway than dermal contact and inhalation. The contribution rates of different sources to non-carcinogenic risks and carcinogenic risks were similar among children and adults, while traffic and industrial sources have a significant impact on health risks. This study will give more insights to control the environmental risks of trace metal(loid)s in national parks. 相似文献
