预处理-混凝-水解酸化-循环式活性污泥法处理制革废水

制革废水水质、水量波动大,污染负荷重,有毒性,较难处理。本工程采用“预处理-混凝-水解酸化-循环式活性污泥法”处理制革废水,研究了C-TECH池曝气时间与CODCr、NH3-N负荷及DO的变化规律。结果表明,控制水解酸化池HRT12.5h,曝气时间8h,C-TECH池污泥浓度4.5g/L,CODCr污泥负荷0.4kg/(kg.d),NH3-N污泥负荷0.07kg/(kg.d),出水可达一级排放标准;通过可编程逻辑控制器PLC、在线DO测定仪及鼓风机变频装置控制DO浓度,用DO浓度作为循环式活性污泥池过程和反应时间控制参数,可节约能耗。

Ethics in the Societal Debate on Genetically Modified Organisms: A (Re)Quest for Sense and Sensibility

Via a historical reconstruction, this paper primarily demonstrates how the societal debate on genetically modified organisms (GMOs) gradually extended in terms of actors involved and concerns reflected. It is argued that the implementation of recombinant DNA technology out of the laboratory and into civil society entailed a “complex of concerns.” In this complex, distinctions between environmental, agricultural, socio-economic, and ethical issues proved to be blurred. This fueled the confusion between the wider debate on genetic modification and the risk assessment of transgenic crops in the European Union. In this paper, the lasting skeptical and/or ambivalent attitude of Europeans towards agro-food biotechnology is interpreted as signaling an ongoing social request – and even a quest – for an evaluation of biotechnology with Sense and Sensibility. In this (re)quest, a broader-than-scientific dimension is sought for that allows addressing the GMO debate in a more “sensible” way, whilst making “sense” of the different stances taken in it. Here, the restyling of the European regulatory frame on transgenic agro-food products and of science communication models are discussed and taken to be indicative of the (re)quest to move from a merely scientific evaluation and risk-based policy towards a socially more robust evaluation that takes the “non-scientific” concerns at stake in the GMO debate seriously.

Analysis on the Relationship between Socio-economy and Development of Science and Technology in Jiaxing City

Currently, the progress of science and technology has become a key factor in promoting economic development. And the backwardness of science and technology at the grassroots level has undoubtedly restricted the process of China＇s construction of socialist new countryside. Taking socio-economy and the development of science and technology in Jiaxing as a breakthrough point, and based on the related data of Jiaxing during 1998-2004, this paper analyzes thoroughly the interactive relationship between socio-economy and the development of science and technology. This paper strives to summarize the development track and model of the grassroots work of science and technology so as to provide local governments with references and grounds for drawing up policies for the local work of science and technology.
