清洁生产审计的总体思路可以表述为:A.→废物在哪里产生———污染源(废物)清单B.→为什么会产生废物———废物产生的原因分析C.→如何减少或消除废物———方案产生和实施通过现场调查和物料平衡找出废物产生并确定产生量,然后针对生产过程所包括的各个方面,分析废物产生的原因。清洁生产审计思路我国国家环保局在参照联合国和其它国家提出的清洁生产审计序的基础上,根据开展B-4项目所积累的经验,提出了适合我国国情的企业清洁生产审计工作程序,将整个审计过程分解为具有可操作性的7个步骤或阶段,分为:1)筹划和组织2)预评估3)评估4)方案… 相似文献

我省推行清洁生产初见成效 总被引:1,自引:0,他引:1
清洁生产是对生产过程和产品实施综合防治战略,以期减少对人类和环境的风险。它以环境与经济协调发展为目标,以节能、降耗、减污为宗旨,以良好的企业管理、合理的工艺、有效的物料平衡及原材料、废物的综合利用为手段,通过工业生产全过程控制,将废物降到最小量,尽可能地使废物资源化和无害化,以消除工业生产对人类与环境的影响。清洁生产已形成世界性潮流,我省的清洁生产始于1994年,其标志是陕西省环境保护局批准成立了陕西省清洁生产指导中心。在国家环保局、国家清洁生产中心的大力支持和指导下,我省率先在“冶金、治炼、医药、… 相似文献

Environmental problems caused by recycling wasted paper at a board paper mill provide the material of this study. Two scenarios have been investigated: The first being the treatment of the end-of-pipe, and the second being the control and management of pollution problems through the application of in-plant control and pollution prevention measures. Comparison between the two alternatives, based on a cost-benefit analysis and compliance with National Environmental Laws was done. From this study it was apparent that the implementation of the pollution prevention measures such as the recovery of fiber, reduction of fresh water consumption, and optimization of white water usage proved to be very cost effective. All the implemented solutions have short payback periods and resulted in great savings compared with the treatment of the end-of-pipe. 相似文献

啤酒废酵母的综合利用 总被引:6,自引:0,他引:6
啤酒废酵母含有丰富的营养物质,许多啤酒厂并没有充分利用,而是作为废弃物排入啤酒废水,增加了啤酒废水的处理负荷和难度。针对这种情况,我们利用本厂啤酒废酵母进行了生产酵母抽提物及营养酱油的研究,取得了满意的效果。不仅获得了优质产品,而且大大降低了啤酒酵母的污染负荷。 相似文献

The main objective of this study is to investigate and evaluate opportunities for implementation of pollution prevention and waste minimization in a chemical industrial company producing poly sulfonated naphthalene formaldehyde which is used as a super plasticizer for concrete. Environmental problems encountered were mainly the highly polluted wastewater and a semi-solid cake containing considerable amount of the final product. Possible modules for remedial measures and their cost estimation were investigated. The proposed remedial modules included recycling of retained water discharge in filter press, recycling of washing water of reaction vessels (reactors), closed circuit cooling system for high-pressure pump, good housekeeping through control of leakage of raw material, products and water and finally utilization of retained residual product from the solid waste. The implemented pollution control measures proved to be cost effective and have short payback periods. Also, minimization of the hydraulic and organic loads in the final effluent was achieved. 相似文献

The Pollution Prevention 1997: A National Progress Report identifies pollution prevention initiatives as potentially the most effective for reducing risks to human health and the environment, as well as the most cost-effective method of environmental protection. So it is no surprise that much of the implementation of pollution prevention by local governments has been driven due to the cost savings it provides. Pollution prevention initiatives have been proven to reduce costs, improve efficiency, reduce risk, reduce liability, and provide a safer work environment. However, as many local governments have experienced budget and resource reductions, their pollution prevention programs have been impacted. Local governments, working to continue pollution prevention initiatives in spite of declining budgets, have had to change their approaches, be creative, and innovate. Montgomery County, Maryland has implemented a number of pollution prevention strategies for its own County operations. The linkages established between cost savings they achieve and environmental benefits provided have been used to continue to expand the County's pollution prevention efforts. This paper provides an overview of the pollution prevention measures and approaches that have been implemented in Montgomery County for its internal operations. 相似文献
