According to the characteristics of wastewater from food (mainly jelly) production,the combined process“Pretreatment+Air fioatation+Anaerobic+Aerobic”has been used for its treatment. The running results show that the process treatment effectiveness is good,and runs stably. The total removing rate of COD is 97%,total removing rate of BOD5 98.5%,total removing rate of SS 94.9%,total removing rate of animal and plant oil 93.4%,and total remov-ing rate of ammonia nitrogen 85.7%. Every index of the effluent is superior to the medium secondary standard re-quirements of Integrated Wastewater Discharge Standard(GB 8978-1996).
