As a kind of predominant technology, Ozone biologically Actived Carbon Method in Drinking water treatment has been extensively applied at home and aboard. In order to achieve purify water and decrease disinfect-outgrowth simultaneously, the quantity of ozone and the process of treatment must adapt to kinds of water quality. So it is very importance of optimization and control in this technology.In this paper, the characteristic of ozone and the mechanism of purify are introduced firstly. Based on advanced technology, this thesis bring forward the optimal scheme and set down general system-drawings and flow charts. Using STEP7-Micro software, we achieve the auto-control aim in drinking water treatment.In practice, the complexity and non-linaerity exit in the system of water treatment, so we apply Fuzzy Control in water treatment and design a kind of controller which structure can be altered according to the using-rate of ozone and the variety of water quality. We use single-chip as control hardware and an software to control the flux of valve , so we achieve the optimization of the treatment.
