A new type of axial dynamic backwashing filter has been developed ,and field tests on the filtration of wastewater containing polymer conducted. The removing effect of oil and suspended matter,backwashing intensity, filter media backwashing duration and filter media backwashing regenerating efficiency are investigated. The results show that the filtration effect on polymer-containing wastewater is very good. The oil and suspended matter removing rates of this process are 96.0%and 78.1%,respectively. The backwashing intensity is 8.8 L/(s·m2),backwashing duration is 15 min,elimination rate of intercepted oil in the filter is 96.23%,removing rate of walnut shell oil filter media is 98.93%. The oil capacity of filter media surface changes obviously ,before and after the backwashing.
