摘　　要：This paper studied the treatment of the landscape river in ChangZhou Scientific and Educational Town by a new integrative apparatus for water purification, which used ozone pre-oxidation-moDified clay-ozone biological activated carbon integrated process. The results indicate that the effectiveness of the algal removal with mentioned integrated process is much higher and the apparatus can operate stably. When the turbidity, chemical oxygen demand （CODMn）, total nitrogen （TN）, total phosphorus （TP） and algae densities of the raw water are 29-38 NTU, 7.45-7.79 mg/L, 2.496-2.981 mag/L, 0.237-0.255 mg/L and 5.78-7.94×10^8 cells/L respectively, it can be reduced to 0.8-1.7 NTU, 1.69-2.84 rag/L, 0.579-0.692mg/L, 0.013-0.038 mg/L, 0.06-0.38×10^8 cells/L. The average removal rates of turbidity, CODMn, TN, TP and algae density can reach 96.4%, 71.5%, 76.8%, 92.0% and 96.9% respectively. The treated water can meet the requirements of class Ⅰ- Ⅱ in Environmental Quality Standard, for Surface Water.
