Paper Title:
Studies on Micro-Polluted Source Water Treatment by Ozone Combined Processes
  Abstract

According to the water quality characteristics, micro-polluted source water treatment by ozone combined processes. The results show that the average removal efficiencies of algae, CODMn, NH4+-N, turbidity, chromaticity by bio-pretreatment filter are 72.0%, 14.5%, 80.5%, 58.6% ,26.0%, respectively; while the whole average removal efficiencies by pre-ozonation tank following bio-pretreatment filter had increased at the different dosages of ozone, such as algae 12.0%, CODMn 19.5% ,NH4+-N 7.5%, turbidity 10.9%, chromaticity 34.5%, respectively; and the optimal dosages of ozone are between 0.7 and 1.5mg/L. Furthermore, compared with the conventional water treatment process, all kinds of combined water treatment processes are better than the conventional one, of which the combined process Ⅲ with granular activated carbon (GAC) adsorption tank is obviously the best, all the average removal efficiencies of algae, CODMn, NH4+-N, turbidity, chromaticity can reach 82%, while whose operation expenditure is higher than any others, so it should be considered comprehensively in the practice.
