Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, this utility model is illustrated:
Fig. 1 shows the structure chart of a kind of pretreatment system for sewage.This pretreatment system for sewage includes between an inlet well 1 and a coarse rack 8, inlet well 1 is provided with inlet well leg 1a, and use the first next door 1b, second next door 1b and the 3rd next door 1d separates, inlet well leg 1a, the space that first next door 1b and the 3rd next door 1d surrounds connects water inlet pipe 5, a debris retaining sand setting basket 2 and slide valve 6 it is provided with in space, debris retaining sand setting basket 2 both sides are provided with the conduit 2a matched with the slideway 3 on inlet well leg 1a and the first next door 1b, slide valve 6 is connected with the limbers 6a on the 3rd next door 1d, it is provided with one in inlet well 1 and connects the fiberglass water inlet pipe 7 of 8 between coarse rack, bottom is provided with sump 4, fiberglass water inlet pipe 7 is provided with inlet opening 7a.
Fig. 2 shows the structure chart of debris retaining sand setting basket.Debris retaining sand setting basket 2 includes square box 2b, lower square box 2f and grid bar 2c, three of upper square box 2b and lower square box 2f connect with the grid bar 2c that multiple spacing are 120mm is fixing, lower square box 2f is provided with base plate 2e and three coaming plate 2d fixing to be connected with base plate 2e, do not set one conduit 2a of each fixing connection in two sides of grid bar 2 at debris retaining sand setting basket 2, corner, top is respectively provided with a hanger rope 2g.Debris retaining sand setting basket 2 all uses Welding Structure.
Use above-mentioned technical scheme, debris retaining sand setting basket 2 can be lifted by the crane above inlet well 1, debris retaining sand setting basket 2 intercepts bulk scum silica frost by the grid of self, by three, side iron plate, cushioning effect is played in water inlet, make to be deposited in into granules such as the sandstones in water the bottom of debris retaining sand setting basket 2, thus play the multiple effects such as debris retaining, sand setting, current stabilization.
Between coarse rack, the inlet well 1 of 5000 × 7500 × 5750 is built in underground on the right side of 8, staggered waterwall, make to flow into water form of zigzag, extend path, delay water velocity, debris retaining sand setting basket 2 is placed on the exit of water inlet pipe 5 and intercepts the sandstone and scum silica frost intake, and installs slide valve 6 and controls the water yield, empties sewage in well during catch pit 4 easy cleaning inlet well 1.Advanced treatment system sewer enters 8 front end between coarse rack by glass reinforced plastic pipe 7, drives water hole 7a into above this glass reinforced plastic pipe 7, allows municipal administration water inlet conflux herein with advanced treating sewer, together between entrance coarse rack 8.
Specifically used process is as follows: municipal wastewater enters inlet well 1 through water inlet pipe 5, flow through debris retaining sand setting basket 2 and slide valve 6 tailing edge gallery form of zigzag, and through fiberglass water inlet pipe 7 enter advanced treating sewer conflux entrance coarse rack between 8, when debris retaining sand setting basket 2 foreign material are more, close slide valve 6, by the crane above inlet well 1, debris retaining sand setting basket 2 is sling, after cleaning out, put back to debris retaining sand setting basket 2, open slide valve 6.
