摘要：
The aim of this work is to investigate the practical effect of the combined advanced oxidation processes (catalytic ozonation-UV/H2O2-biological activated carbon (BAC)) on improving the water quality of micro-polluted raw water from Huaihe river. The results suggest that catalytic ozonation combined with BAC process could improve the water quality by enhancing the removal efficiency of UV254, DOC, ammonia nitrogen, CODMn and trihalomethanes formation potential (THMsFP), while it did not bring any bromate risk because of low bromate formation after catalytic ozonation. The average removal rates of UV254, DOC and CODMn by catalytic ozonation were 21.8%, 8.1% and 10.8%, respectively. And the BAC filter could efficiently remove the ammonia nitrogen in water with a highest removal rate of 61%. The average reduction percentages of DOC and CODMn by BAC process were 10.4% and 15.3%, respectively. Furthermore, the catalytic ozonation process could significantly decrease THMsFP, with an average removal rate of 34.9%, and the maximum rate could arrive to a percentage of 53.2% during the test. However, UV/H2O2 process in this project could not furthered improve the water quality of the Huaihe river with seasonal characteristics of low temperature and low turbidity. Therefore, the combination of catalytic ozonation-UV/H2O2 is of little significance, but catalytic ozonation-BAC-sand filter process is a necessary combination mode of advanced oxidation process to ensure the safety and reliability of drinking water in the practical production design. Considering the decomposition role of UV for residual ozone, catalytic ozonation-UV-BAC-sand filter process are the recommended processes as AOPs for micro-polluted river water. The results from the demonstration project can provide a reference for improving the quality of effluent water with low temperature and turbidity and reconstruction for the drinking water treatment plant. © 2017, Editorial Board of Journal of Harbin Institute of Technology.
