以豌豆粉丝废水分离渣为原料,对豌豆纤维的提取过程进行研究.通过耐高温α-淀粉酶、糖化酶、蛋白酶多酶分步水解的方法,去除豌豆渣中的淀粉和蛋白质.结果表明,耐高温α-淀粉酶添加量1.2％,反应温度为90℃,反应时间为60 min的条件下,豌豆膳食纤维的提取率最高;糖化酶加酶量为4.5％,反应温度为60℃,反应时间为110 min,pH为5.0的条件下,可达到良好的水解效果;蛋白酶的加酶量为1.0％,反应温度为55℃,反应时间为80 min,pH为8.5的条件下,酶解效果最佳.此时豌豆粉丝废水分离渣的膳食纤维含量可达到94％ 以上.     

一体式A/O反应器处理高浓度有机废水实验研究

采用一体式A/O工艺对传统工艺进行改造,进行了一体式厌氧-好氧反应器(IAOR)生物流化床处理高浓度有机废水启动与运行实验。实验结果表明:在16～20℃下,25d完成反应器启动;在20～28℃下,反应器运行40d后,HRT缩短为20h,进水CODCr浓度提高为11800mg/L,容积负荷增加为13.2KgCOD/(m3·d)时,厌氧反应区CODCr去除率可达73%,好氧区可达95%,IAOR系统可达99%。证明IAOR反应器处理效率高,启动快,抗冲击负荷能力强,出水水质优良,适合于处理浓度高、水质水量变化大的有机废水。具有良好的工业应用前景。     

基于三阶段DEA模型的我国医药制造业技术创新效率研究

采用可以剔除环境因素和随机误差影响的三阶段DEA模型对2000-2011年我国28个省、直辖市和自治区医药制造业的技术创新效率进行实证研究,结果表明我国医药制造业技术创新效率较低,并且创新效率值会受到环境因素的影响;创新效率值较低的原因主要是纯技术效率值的低下,另外规模效率的作用也不容忽视。各地区应加大对医药制造业技术创新的投入,提高规模效率,同时完善创新管理和制度体系,以效率为导向配置创新资源,最终达到提高综合效率的目的。     

“AIDS is Not a Business”: A Study in Global Corporate Responsibility – Securing Access to Low-cost HIV Medications

At the end of the 1990s, Brazil was faced with a potentially explosive HIV/AIDS epidemic. Through an innovative and multifaceted campaign, and despite initial resistance from multinational pharmaceutical companies, the government of Brazil was able to negotiate price reductions for HIV medications and develop local production capacity, thereby averting a public health disaster. Using interview data and document analysis, the authors show that the exercise of corporate social responsibility can be viewed in practice as a dynamic negotiation and an interaction between multiple actors. Action undertaken in terms of voluntary CSR alone may be insufficient. This finding highlights the importance of a strong role for national governments and international organizations to pressure companies to perform better.

有机硅废水达标处理工艺的探讨与应用

本文介绍了一种处理有机硅废水的新的工艺组合,即铁炭微电解——水解酸化——UASB——MBR联合处理法,第一步铁炭微电解很明显的改善了有机硅原水的可生化性,BOD/COD值可达0.52;进入水解酸化池后,部分大分子降解成小分子物质,可生化性进一步提高;随后进入UASB,在颗粒污泥的作用下,COD去除率达到81%;在曝气池中,设置MBR,进一步去除了COD,去除率为96%;最终出水能达标排放。

Trade-offs and Synergies: Horizontalization and legitimacy in the Swiss wastewater sector

Recent public sector reforms have led to horizontalization, where public service providers have increased autonomy from the state. Such changes lead to queries about democratic responsiveness (input legitimacy), democratic procedures and efficacy (throughput legitimacy) and effectiveness (output legitimacy). The following question thus emerges: how and why does horizontalization affect input, output and throughput legitimacy? This inquiry is addressed by analysing two Swiss wastewater service providers with differing degrees of horizontalization. The analysis indicates that horizontalization leads to more synergies than trade-offs between the legitimacy dimensions. Particularly, input and throughput legitimacy can play a pivotal role in attaining citizens’ acceptance.
