Abstract:Treatment of paper mill midcourse wastewater with coagulant FPAS was studied. The effects of acidity,amounts of coagulant and additives,stirring speed,stirring time and settling time on COD removal rate were evaluated. Results showed that under conditions of pH 6.0~9.0,FPAS diluent concentration 4 mL/L,stirring speed 120 r/min,stirring time 6 min,followed by addition of 3.5 mL of 1.5‰ additive(m/m)and stirring another 4 min and 10 min of settling time,the removal of COD reached around 88%,which was much better than that achieved by using the traditional coagulant. This process is simple and of practical importance. |
