The Combination Process of Ozone/Ultraviolet/Biological Activated Carbon Filter for Treatment of Huaihe Micro-Polluted Water

Abstract:

Aim at experimenting the micro-polluted characteristic of Huaihe River water, a pilot-scale test by the combination process of ozone/ultraviolet (UV) /biological activated carbon (BAC) filter for advanced treatment of drinking water was applied. The removal efficiency of general pollution indexes by combined process with different ozone dosages (1.0~3.0 mg/L) was investigated. Along with the increase of ozone dosage, the removal efficiency of COD_Mn and UV₂₅₄ generally increased in ozone/UV oxidation process; The removal effect of NO₂^--N by ozone/UV oxidation was obvious; The removal of turbidity and NH₃-N was mainly in BAC filter phase; When the ozone dosage was 2.0~2.5 mg/L, the general pollution indexes had gotten satisfying results, thus it was not necessary to increase the ozone dosage.
