For the treatment effeciency that improves surface filtration and biological catalytic oxidation filter tank, the utility model provides a filtering duct and filter equipment thereof. Its key facilityincludes catch basin, filtering ponds, water pump, filtering duct, back flow, outlet pipe and returns mud pipe and corresponding valve, the water pump once filters in carrying filtering duct with sewage, and excess sludge discharges through the outlet pipe, and return sludge returns the catch basin through the back flow, and once filterable filtrating is discharged from another outlet pipe afteranother filtering duct carries out secondary filter, and the mud in the filtering ponds flows back to the catch basin through returning the mud pipe, regularly switching valve changes filtering duct'sfiltration order to accomplish the back flush operation. Be used for solid -liquid separation to improve the effective filtration area, realized that it filters, simplifies backflush operation, improves water yield, the volume
