The course of work of the present invention is following:
1, tandem is filtered simultaneously
When the former water water yield is big and water quality is relatively poor or effluent quality had relatively high expectations, adopt double-filtration lattice 2n series connection to work simultaneously.Former water utilizes pressure to get into one-level filtration lattice 2a (water intaking valve on the cascade filtration lattice 2b is in closed condition at this moment) from the former water water inlet pipe 5 on closed tank body 1 top through elevator pump; Former water is filtered to one-level filtration lattice 2a bottom through filter course, supporting layer from top to bottom and obtains the one-level filtered water; Tube connector 4 is delivered to cascade filtration lattice 2b top through the one-level filtered water that pressure filters lattice 2a bottom with one-level, and the one-level filtered water is filtered to cascade filtration lattice 2b bottom through filter course, supporting layer from top to bottom and obtains cascade filtration water.Entire equipment is divided into double-filtration, and the concrete grating of this double-filtration is: one-level is filtered lattice 2a and is adopted bigger homogeneous filtering material; Cascade filtration lattice 2b adopts less homogeneous filtering material.Backwash water inlet pipe 7 by correspondence after tank body 1 bottom backwashing pressure water inlet and gas mix gets into one-level filtration lattice 2a and cascade filtration lattice 2b respectively; After the filtrate and supporting layer among the lattice 2n filtered in whole from bottom to top flushing two, backwashing water was flowed out by the backwash outlet pipe 8 of correspondence respectively from rhone.Certainly, one-level is filtered lattice 2a and both backwashes separately of cascade filtration lattice 2b, also can carry out backwash simultaneously.
