Biodegradation kinetic of organic compounds of acrylic fiber wastewater in biofilm

A group function relation curve between flux (J) and bulk phase concentration of substrate (S) was set up. The biodegradation kinetic of organic compounds of acrylic fiber wastewater in biofilm is studied (the treatment technology is coagulation/sedimentation-anoxic/aerobic biofilm process), and the results showed that the concentration of non-degradation pollutants in effluent is 77 mg/L. In aerobic zone, the half-rate constant is 72.84 mg/L, the maximum removal rate of organic compounds at unit area filler is very low, 0.089 g/(m2 x d), which corresponds to the fact that there are some biorefractory compounds in the wastewater.
