Construction of Theory for Water and Wastewater Treatment Technology

水与废水处理技术是历史悠久的工程领域之一。随着社会的发展和人们对饮用水水质和水环境的关注，对水质的要求越来越高。为了满足水质要求的目标，各种给水方法和废水处理技术得到了开发和应用。然而，据说开发过程依赖于相当经验性的进展，部分原因是过去的技术高度依赖于当地的水质条件，因此很难推广应用该技术。在水和废水处理过程中也确实有一些共同的原则，需要将在处理过程中观察到的共同原则系统化。共同原则的系统化是理解和支持理论…的起点水和废水处理技术的更多发展。理论的发展是学术领域持续、可持续发展的关键因素，而理论发展的缺失仍然是工程领域处于欠发达阶段。在本研究报告中，对絮凝的流体力学方面和絮体强度估算方法方面的一些进展进行了综述。同时指出，污水生物处理的可能发展取决于由ORP计算得到的自由能变化，利用基因技术进行的生物质群落分析对污水处理设施的设计和运行有很大的帮助。水和废水处理过程模型的建立是发展水和废水处理过程理论分析的重要内容。目前的研究表明，理论方法对水和废水处理过程等非常经验性的过程的重要性。较少

The water and wastewater treatment technology is one of the engineering fields of long historical background. The requirement for the water quality is coming severer depending on the social development and people's concerns about water quality of drinking water and water environment. To meet the goal of the requirement of water quality, various methods of water and wastewater treatment technologies have been developed and applied. However, it is said that the development process depends on the rather empirical progresses, partly because the technologies used to be highly dependent on the local conditions of water quality and it is not easy to generalize the technology for general application. It is also true that there are some common principals among the water and wastewater treatment processes and it is needed to systematize the common principals observed in the treatment processes. The systematization of the common principal is a starting point to understand and support the theoreti … More cal development for water and wastewater treatment technology. The theoretical development is a key factor for the continuous and sustainable development of the academic field and the lack of the theoretical development remains the engineering field in the state of underdevelopment stage. In the report of the present study, some progresses of hydrodynamic aspect of flocculation and floc strength estimation method. It is also presented that the possible development of biological wastewater treatment is depend on the free energy change evaluation from the ORP calculation and that the biomass community analyses by genetic technologies could be very helpful to design and operation of wastewater treatment facilities. The progress of the model formation for the water and wastewater treatment processes is very important in the development of theoretical analyses of the processes. The present research showed the importance of theoretical approaches to such very much empirical processes as water and wastewater treatment processes. Less
