Abstract:Jar tests were conducted to investigate the performance of enhanced primary treatment processes for low·concentra—
tion municipal wastewater行om South China by using composite flocculant combined with bio.flocculants Pullulan and
poly.aluminum.chloride fPAC).The optimum dosage for composite flocculant and conditions for flocculation were determined.
The experimental results indicated that composite flocculant had high emciency for removing over 95%ofturbidity,over 58%of
CODr,(chemical oxygen demand determined with potassium dichromate),over 9 1%6f TP(total phosphate),and over l 5%of
NHl.N.Moreover,it could improve sludge settling and dehydration properties,and decrease the treatment cost.
