Erratum

The influence of soil macro-porosity and manure on atrazine (6-chloro-N-ethyl-N′-(1-methylethyl)-1,3,5-triazine-2,4-diamine) transport was investigated under laboratory conditions using disturbed and undisturbed soil columns. The macro-porosity in the soil column was obtained with CT scanning technique. Liquid manure was applied at the surface of soil column, 19 cm long and 8 cm in diameter, at a rate of 60 m³/ha. Experimental results revealed that atrazine moves faster through the soils in the presence of manure compared to soil without application of manure. The average time for elusion and the relative peak concentration in the disturbed soil column without manure was 14.5 h and 3.1%, respectively compared to 11.0 h and 6.9% in the presence of manure, respectively. Similar behavior was observed in the case of disturbed soil columns. Soil macro-porosity has shown large impact on atrazine transport, especially in the presence of manure.     

紫茎泽兰的化学防除及生态修复效果

紫茎泽兰是我国重要的外来入侵生物,一旦入侵,就排挤当地物种,很快成为优势种群,在西南地区已对当地的农业、畜牧业,以及生态环境造成严重的破坏.2年的试验和示范结果表明,磺酰脲类除草剂嘧磺隆187.5～375g/hm2(有效成分,下同)、噻吩磺隆375g/hm2、氯嘧磺隆375g/hm2和吡啶类除草剂氨氯吡啶酸1 080g/hm2对紫茎泽兰均有优异的防除效果.而2,4-滴1 500g/hm2、乙羧氟草醚150g/hm2、氟磺胺草醚500g/hm2、咪唑乙烟酸1 500g/hm2、嗪草酸甲酯50g/hm2、环嗪酮2 500g/hm2、氯草定750～1 500g/hm2不能完全杀死紫茎泽兰.针对山区水源短缺,运水不便的的问题,通过在除草剂中加入2 L/hm2机油乳油,采用很低容量喷雾法,用水量可由常量喷雾的900～1 200L/hm2减少到30～40L/hm2,施药效率较常量喷雾提高8～10倍.此外,还可将除草剂制成颗粒剂或采用毒土法撒施,不需施药器械,且可以节省大量水运输费用.紫茎泽兰用上述除草剂防除后,能选择性地促进非靶标植物的生长.大面积防除2年后,生态恢复率为40%～90%.     

Identification of potential applications for recycled polymeric multi-material

Abstract

This research aims to characterise a recycled polymeric multi-material, explore potential areas of application for it and analyse the eventual impacts of the introduction of this new recycled material (NRM) on end-of-life activities. Thus, this research presents a practical study regarding recycled polymeric multi-material from toothbrushes. A preliminary characterisation (via density determination, tensile test and dynamic mechanical thermal analysis – DMTA) and data analysis using the Cambridge Engineering Selector (CES-Edupack 2013) software have been done. The study also presents an analysis of the impacts of introducing the NRM into end-of-life activities. Results shows that, based on the properties considered in this study, NRM may have potential for new applications. The impact on recycling networks indicates that it is a positive solution that would improve process variable efficiencies, maintaining material value as long as possible in industrial closed-loop life cycles. However, an in loco analysis of the treatment of waste containing the NRM is necessary.     

在役装置HAZOP的应用分析及问题探讨

HAZOP分析方法已经在国内的石化企业得到了广泛应用,其分析方法已经被大家熟知,但仍有很多人对HAZOP方法存在某些片面的理解,这在一定程度上影响了HAZOP分析的效果.首先以丙烷脱沥青装置进行的HAZOP分析为案例,介绍了HAZOP分析对于在役装置工艺安全管理的意义.进而,根据HAZOP分析方法的特点及不足以及HAZOP准备阶段出现的问题,讨论了如何完善分析效果、强化分析作用,从而使HAZOP分析更好地服务于在役装置工艺安全管理.
