- Abstract:
- The effectiveness of outsourced treatment of industrial wastewater in M sewage purification plant in Shenzhen was discussed. The changes of the main pollutant load, B/C ratio, C/N ratio, C/P ratio and other characteristic pollutants in influent of the sewage purification plant were compared before and after the pilot outsourced treatment of food industry wastewater in M sewage purification plant. The quality of effluent from the pilot sewage purification plant stably met the discharge standard, and the animal and vegetable oil and LAS contained in the food industry wastewater did not significantly affect the influent quality of the sewage purification plant. The influent B/C ratio, C/N ratio and C/P ratio did not show regular increase. The theoretical analysis indicated that the food industry wastewater only accounted for 0.46% of the influent of M sewage purification plant in the same period. However, the BOD5 loading rate accounted for 7.41% of the total influent loading rate, which still made a certain contribution to the improvement of influent BOD5 entering into the sewage purification plant.
