Abstract :
The simulated experiments were conducted to research the removal efficiency of protein through heating, plus three flocculations(PAC, PFC, PAM)on potato starch wastewater. The cleaning efficiency was studied by changing the experiment conditions such as the kinds of flocculation,the quantity of flocculation, the pH of the wastewater, the static time. Through making a comprehensive analysis to the wastewater quality before and after the treatment, the processing costs and other factors, the results showed that it was more feasible to remove the protein in potato wastewater by pulsing PAC. At this point, the removal rate of COD and protein in the wastewater could respectively reach 42.6% and 57.6%.
