| Abstract: | In the exist of natural manganese minerals, sodium hypochlorite and UV irradiation, different kinds of factors on influencing disperse blue 2BLN wastewater degradation were discussed. Under the best conditions that manganese minerals and sodium hypochlorite concentration was 20g/L and 20mL/L, respectively, that light intensity was 2000w,that illumination distance and time was 10cm and 60 min respectively,that pH 7.5to 9.5, the COD removal rate was 52 %,and decolouration rate was 93%. |
