Nowadays, with scientific and technical development, water supply panies need to form a new conception of water quality and establish new effective protective system of drinkable water. Accoding to the data of researches and projects, the intensified unit process and multibarrier process are considered to be effective methods to protect the water quality. In my design, I not only added an ozone pretreatment process in order to strengthen the effect of coagulation, but also intestified the filtration process via introducing shutter filter to descrease
