我省编制工业用水定额标准

我国的水资源相当贫乏，而椒江的水资源人均占有率更低，节约用水对我们每个人来说有较大的现实意义。据统计，目前企业排放污水的很大部分是由于管理不善或没有综合利用所引起的，只有10％左右是由于缺乏环境保护措施所造成的。现我国的工业用水每年约为500多亿m^3，     

试论主体性教育与德育的关系

主体性教育和德育既有区别又有联系。两者的基本内涵和理论依据、教育目标、教育内容与任务侧重点等是有区别的，但它们又是有密切联系的，其教育内容和终极教育目的具有相同性。并且，加强主体性教育，有助于德育目标的多层化和具体化，德育内容的完整化和现实化，德育过程的主体化和科学化，因而是提高德育实效的关键。     

自养型生物过滤器硝化氧化一氧化氮

Carbon foam-a, kind of new engineering material as packing material was adopted in three biofilters with different pore dimensions and adapted autotrophic nitrite nitrobacteria to investigate the purification of nitric oxide (NO) in a gas stream. The biofilm was developed on the surface of carbon foams using nitrite as its only nitric source. The moisture in the filter was maintained by ultrasonic aerosol equipment which can minimize the thickness of the liquid film. The liquid phase nitrification test was conducted to determine the variability and the potential of performance among the three carbon foam biofilters. The investigation showed that during the NO2--N inlet concentration of 200g·L-1-min-1 to 800g·L-1-min-1, the 24PPC (pores per centimeter) carbon foam biofilter had the greatest potential, achieving the NO--N removal efficiency of 94% to 98%. The 8PPC and 18PPC carbon foam biofilters achieved the NO2--N removal efficiency of 15% to 21% and of 30% to 40%, respectively. The potential for this     

用电渗析法纯化回用含铅废水

在实验室范围内对蓄电池厂的含铅废水用电渗析法进行了处理研究。在常温、工作电流密度为3A／cm^2 、物料流量为300L／h的实验条件下,含铅废水经5～6次循环处理,出水的电导率在10μs／cm以下,达到了专业标准ZBK84004-89《铅酸蓄电池用水》中的标准,处理后的废水可作为纯水回用到蓄电池的配酸工艺,可望实现废水的“零排放”,具有较好的经济效益和社会效益;同时实验还得到描述设备特性的经验模型Jlim=10．379V^05324C。     

OLED有机发光显示技术

目前,市场上常见的显示技术有CRT和LCD两种。CRT体积大、耗电,在环保和安全方面不是很理想。而LCD,尤其是有源矩阵薄膜晶体管型LCD,则投资大,工艺复杂,并且制造困难,价格较高。 针对上述问题,科学家和工程师们正在研制新的平板显示技术,其中最有前途的一种就是有机发光显示技术OLED (Organic LightEmitting Display)。采用这种技术制造的显示器件,不仅视角更宽,亮度更高,响应速度更快,而且更轻、

STUDY ON MATHEMATICAL MODEL OF JIG PROCESS

Mathematical model is a powerful means of prediction, simulation and optimization of jig process. And it is also an important part in computer control system. Jig process Is divided Into two sub-processes, stratifying process serially followed by separating process. Taking stratifying process as state transition process of particles in step with jig work cycle, the mathematical model of stratifying is established with Markov chain theory; By analyzing the characteristics and float-sink data of jig, the mathematical model of separating process was submitted. The physical meaning of parameters of the models are explaine~l; the relationship between model and partition was discussed. The fitting result was good with the model.     

生物转鼓过滤器反硝化去除NO的模型研究和实验验证

在厌氧条件下,对利用生物转鼓过滤器(Rotating Drum Biofilter,简称RDB)反硝化净化一氧化氮(NO)废气的过程进行了理论模型探讨,并用实验结果进行了验证.在分析NO在RDB内的传质-反应过程基础上,建立了滤料微单元内NO在气相、液相内的质量守恒方程,结合生物膜内NO的传质方程和厌氧条件下的Monod微生物反应动力学方程,最终得到了NO在RDB中的浓度分布方程及NO去除效率方程.模型计算值与实验结果比较表明,两者去除效率的变化趋势互为一致,模型能够较好地描述RDB对低浓度(<600 mg·m-3)NO的去除过程,但因模型未考虑RDB内营养液对NO的吸收作用等因素,模型计算值比实验结果约低10%.
