Th r sults show d that turbidity r moval rat of int grat d proc ss was 24. 6%100. 0% . M an r moval rat of potassium p rmanganat in sand filt r unit and ultrafiltration unit was 18. 7% and 67. 5% r sp ct iv ly. Most of ammounia nitrog n was r mov d in sand filt r unit, and t h total r moval rat rang d 1. 0%77. 6% for int grat d proc ss. M icroscopic obs rvation show d that th biological phas s in sand f ilt r w r mainly zooglo a and m tazoa, w hich could ff ctiv ly pr v nt th jam of sand filt r . Finally , it w as found that 10% of NaOH solution was sup rior to 10% H Cl solut ion for m mbran cl aning .
