计算机模拟在污水处理厂改建设计中的应用

Application of computerized simulation for wastewater treatment plant reconstruction

根据国际水质协会的活性污泥1号模型,结合Takacs的二沉池模型,应用Delphi编译软件,在Windows平台上自行开发了污水处理模拟系统;通过对上海市某采用A/O工艺的污水处理厂的模拟,确定了模型的参数并对模型进行了校正。根据模拟结果对污水处理工艺提出改建的设计方案:没有内回流,A/O两段等体积的运行方式。

With the help of Delphi Compiler under Windows, developed a computerized simulating system of activated sludge process, which combined the activated sludge model 1 (ASM1 ) and the Takacs's (model of secondary sedimentation tank). Based on the developed simulating system, illustrated the computer simulating method by simulating one A/O process wastewater treatment plant in Shanghai and some advices to innovate the process are suggested that no inner circumfluence and the volume of anaerobic and oxidative process are equivalent.
