Effects of White-Rot Fungus Trametes Sp.lg-9 Treatment on Properties of Chlorine-Containing Bleaching Wastewater

Abstract:

Effects of white-rot fungus Trametes sp.lg-9 treatment on properties of chlorine-containing bleaching wastewater were investigated. Trametes sp.lg-9 was cultured in chlorine-containing bleaching wastewater under optimal growth conditions, COD sharply decreased from 10740mg/l to 7811mg/l after 5 days; chroma firstly increased from 6212 degree to 7272 degree at 5 days and then declined to 5303 degree; lignin content firstly increased to 0.33 g/l and then decreased to 0.323 g/l. Separating the crude enzyme solution to treat chlorine-containing bleaching wastewater, demonstrating the suitable temperature of the crude enzyme treatment is 40 °C and the optimum pH value is 5.6. COD, chroma and lignin content of chlorine-containing bleaching wastewater can be significantly reduced by crude enzyme treatment on conditions of low dosage and short time.
