Abstract:

The treatment effect of the aerobic degrading strains on the wastewater from Shihezi Tianye Tomato Products Co.，Ltd. has been studied. The results show that the time of sludge acclimation could be effectively shortened after adding the aerobic degrading strains. Within 41 treating days，when the average COD of the influent is 743.07 mg/L，the average COD removal rate is 59.27%，the average effluent COD is 278.79 mg/L，and the pH and SS are 7.04 and ≤150 mg/L，respectively. The effluent quality is in accordance with the requirements of the third class of Integrated Wastewater Discharge Standard（GB 8978-1996）. The highly efficient aerobic degrading strains could guarantee that the effluent reaches the discharge standard and solve the difficulties of sludge preservation and acclimation in unproductive phase.
