The effect of color removal on the polluted raw water of water sources by the biopretreatment action of biocontact oxidation process with the elastic packing and micropore aerator has been studied. The research results show that the water purification biopretreatment can reach a color removal efficiency of 19%～43% for the raw water of water sources under the conditions of normal temperature 20～28 ℃，CODMn in polluted water sources 6～11 mg/L，chromaticity 30～40,the running parameters for the water purification biopretreatment HRT 1.4 h,gas∶water ratio 0.5∶1,and DO 7～9 mg/L. And the water purification biopretreatment can reach a color removal efficiency of 13%～22% for the raw water of water sources under lower water temperature 7～16 ℃，CODMn in polluted water sources 6～10 mg/L,chromaticity 32～35，the running parameters for the water purification biopretreatment of purified water HRT 1.4 h,gas∶water 0.5∶1,and DO 8～10 mg/L.
