垃圾渗滤液是一种危害较大的高浓度有机废水,处理难度较大。因此,城市生活垃圾填埋场垃圾渗滤液处理是目前填埋场设计和运行中遇到的一个比较棘手的问题。南通市城市生活垃圾填埋场垃圾渗滤液处理工程从2004年5月28日开工,2005年8月6日通过了环保局验收,2006年8月通过整体竣工验收。该工程占地1080m2,采用一级反应沉淀+UASB反应+卡鲁塞尔氧化沟+二级A/O+消毒处理工艺,总投资1900万元。 相似文献

There is widespread consensus that landfill of waste electronic and electric equipment is not an acceptable end-of-use management option. Diversion from landfill, either through voluntary or mandatory take-back and collection programs, overwhelmingly leads to the recycling of e-waste, which typically consists of the recovery of a limited number of metals. Cell phones are currently one of the few electronic products, if not the only one, that also have a thriving reuse market. In fact, more handsets are reused than recycled. Cell phones therefore offer the rare opportunity to compare closed-loop supply chains for e-waste reuse and recycling. In this paper, we examine the economics of cell phone reuse and recycling based on detailed primary data collected from reverse logistics, reuse and recycling operations in 2003 in the UK and in 2006 in the US. We show that while cell phone reuse has a healthy profit margin, handset recycling is currently a by-product of reuse. 相似文献

Composite recycling technologies have been developed to tackle the increasing use of composites in industry and as a result of restrictions placed on landfill disposal. Mechanical, thermal and chemical approaches are the existing main recycling techniques to recover the fibres. Some optimisation work for reducing energy consumed by above processes has also been developed. However, the resource efficiency of recycling composites at the workshop level has never been considered before. Considering the current trend of designing and optimising a system in parallel and the future needs of the composite recycling business, a flexible flow shop for carbon fibre reinforced composite recycling is modelled. Optimisation approaches based on non-dominated sorting genetic algorithm II (NSGA-II) have been developed to reduce the time and energy consumed for processing composite wastes by searching for the optimal sub-lot splitting and resource scheduling plans. Case studies on different composite recycling scenarios have been conducted to prove the feasibility of the model and the developed algorithm. 相似文献
