Ozonation process for the regeneration and recycling of Spanish green table olive fermentation brines

Treatment with ozone broke down the most characteristic polyphenols present in the fermentation brines of green table olives. The ozone required for their complete elimination was 15 and 7 mg/L in acidic solutions (pH 4.0) and alkaline conditions (pH 10.0), respectively. The usual microbial population of brines, lactic acid bacteria and yeasts, was simultaneously eliminated in parallel but needed higher ozone levels in acidic conditions. The ozone treated brines were then filtered through a 0.45 μm pore size and diluted (1:1) and re-used as cover brine for plain and pitted olive packing. After 3 months equilibrium, the cover brines from regenerated brines had slighter poorer colour and slightly higher pH. Fruits packed with diluted (1:1) ozonated brines in alkaline conditions had higher firmness and similar organoleptic characteristics to those using fresh brine. The partial regeneration and reuse of fermentation brines may be a cheap and technologically simple alternative for reducing the environmental problems derived from the high polluting charge of green olive fermentation brines.     

浅谈城市生态公园的改造——以湘潭市杨梅洲生态公园为例

随着人类“回归自然”热情的高涨．一种以“人与自然和谐”为中心,提倡环保的森林生态旅游成为国际生态旅游的新时尚。本文旨在研究城市生态公园在改造设计中所出现的共性问题和解决的策略。整个研究将以城市生态公园的改造设计为主体进行研究分析。城市旧生态公园目前面临着缺乏与城市的有机联系：公园个性缺失：景观空间结构简单、类型单一：公园原有要索丰富但景观效果及功能落后于时代的发展等诸多问题。针对这些问题,本文以湘潭市杨梅洲旅游景点规划设计为例,提出了公园与城市开放空间的融合,公园个性特征塑造以及以景观空间重构,原有要素的有机更新等策略,以期为城市旧生态公园改造设计提供参考性建议。

Requirements for Interfacing IP-Components in Re-configurable Platforms

When mapping large and high-throughput signal processing applications onto heterogeneous platforms, parts of these applications are assigned to re-configurable components. Automating such mappings without delving deep into details implies the (re-) use of IP components. When it comes to 1) relying on IP components in system-level and (re-configurable) platform-based design, and 2) porting of such designs across platforms, it is not well known how to integrate both IP libraries and portability requirements into the design flow. To investigate these uncertainties, we have conducted four case studies around the (re-)use and interfacing of IP components. One is focusing on the porting issue, one is dealing with a new automated task-level mapping method, one is evaluating a HW-SW commercially available co-design method, and one is about standardization of interfaces for IP wrapping. The case studies reveal the weakness of otherwise highly desirable system-level design methods when evaluated with respect to fast, accurate, and systematic IP integration.

Re-use of water treatment works sludge to enhance particulate pollutant removal from sewage

This paper attempted to study the feasibility of reusing water treatment works sludge ("alum sludge") to improve particulate pollutant removal from sewage. The main issues focused upon were: (1) the appropriate dosage of the alum sludge, (2) the appropriate operating conditions, and (3) the possible mechanisms for enhancement by adding alum sludge. Actual alum sludge and sewage were applied to a series of jar tests conducted under various conditions. It has been found that both the SS and COD removal efficiencies could be improved by the addition of the alum sludge, which was mainly attributed to the removal of relatively fine particles with a size of 48-200 microm. The appropriate dosage of the alum sludge was determined to be 18-20 mg of Al/L. Increasing the mixing speed or reducing the floc size of the alum sludge enhanced the SS and COD removal and the dispersed alum sludge could remove particulate contaminants with smaller size than the raw sewage. ToF-SIMS evidence revealed that the aluminum species at the surface of the alum sludge were effectively utilized for improving the SS and COD removal. It was postulated that the sweep flocculation and/or the physical adsorption might play key roles in the enhancement of particulate pollutant removal from sewage.
