Network on veterinary medicines initiated by the European Federation For Pharmaceutical Sciences

The European Federation for Pharmaceutical Sciences (EUFEPS) was founded 25 years ago by more than 20 national pharmaceutical societies and faculty members. As a pan‐European organization, it brings together pharmaceutical societies as well as academic, industrial and regulatory scientists engaged in drug research and development, drug regulation and education of professionals working in these fields. EUFEPS represents pharmaceutical sciences in Europe and is recognized as such by both the European Commission and the European Medicines Agency. EUFEPS cooperates with the European Federation of Pharmaceutical Industries and other European organizations and maintains global connections with agencies such as the US Food and Drug Administration and the American Association of Pharmaceutical Scientists. EUFEPS has established specified networks forming the basis of its activities. The creation of a Network on Veterinary Medicines is prompted by the manifold problems resulting from the use of veterinary drugs and its inherent interconnections with human medicine, environmental and public health. A long‐term goal of this initiative was to expand the spectrum of available therapeutics for use in animals, including the development of innovative delivery systems.     

城镇污水处理厂供配电系统分析

污水处理已成为城市建设中必不可少的环节,所以对相应的配套工程也提出了更高的要求,本文将对污水处理厂的供配电系统进行简要的分析。     

改性木屑处理含铬废水的研究

采用磷酸改性木屑后用于含铬废水吸附处理,探讨废水pH值、处理时间、木屑投加量、处理温度4个因素对铬去除率的影响;并拟合25℃改性木屑吸附处理含铬废水的动力学、等温线方程,估算热力学数据。结果表明:木屑对含铬废水有较强去除力,改性木屑去除力加强;改性木屑处理20ml浓度为50mg/L含铬废水的适宜条件为pH值=1～4,处理时间90min,木屑投加量1g,处理温度20～30℃;改性木屑吸附处理含铬废水的动力学特性符合颗粒内扩散方程和二级吸附速率方程;吸附等温线方程符合Langmuir吸附;25℃吸附过程ΔH=-20.489kJ/mol,ΔS=-78.426J/(mol.K),ΔG=2.89kJ/mol。     

重庆南温泉洗浴废水用作植物灌溉水的可行性研究

重庆市温泉资源丰富,温泉洗浴废水运用于绿地灌溉可以节约成本,缓解城市的水危机。温泉洗浴废水对植物生长有正负两方面的影响,与植物的种类,温泉洗浴废水的水质等因素有关。实验以重庆市常见的两种绿地植物——冷水花木春菊为研究对象,对温泉洗浴废水中影响植物生长的pH、固体悬浮物、高锰酸钾,总溶解性固体4个常见指标进行了浓度值对比实验。运用对相对电导率拟合Logistic方程求半致死浓度值的方法,确定绿地植物所能耐受的上限阀值。以此为基础对温泉废水进行相关处理,使温泉废水既可以达到灌溉绿地的水质标准,又能最大限度地降低废水处理成本,从而充分利用水资源。     

投加硅藻土对城镇污水处理厂出水水质影响研究

对好氧池出水混合液进行了加药絮凝试验，探讨了加药量、污泥浓度对絮凝沉淀效果的影响，并通过生产性试验，验证了试验结果的正确性，从而解决了某污水处理厂因进水水质波动影响，出水SS不能稳定达标的问题。     

维生素C废水厌氧处理生产运行的新技术研究

对生产规模上流式厌氧污泥过滤器处理维生素Ｃ废水的工艺流程和设备进行了合理的改革，以厌氧出水回流与高浓度废水混合稀释降低进水ＣＯＤ浓度，提高进水的总碱度，同时控制反应器水力负荷，从而提高了反应器的处理能力。     

Bubbleless Aerated Membrane Bioreactor for Ramie Degumming Wastewater Treatment

Through introducing the principle of bubbleless aerated membrane bioreactor, the traditional membrane bioreactor was improved. It could be obtained that the removal efficiency of COD and NH3 - N in bubbleless aerated membrane bioreactor increased 4% and 2% than that in traditional membrane bioreactor, respectively. Adopting bubbleless aeration as reflushing air which not only increased DO in the MBR, but also advanced the oxygen utilization, and the energy consumption decreased as well.
