The apparatus for treating sewage that contains solid impurity
Technical field
The present invention is a kind of sewage disposal device, and is specifically a kind of to producing and sanitary sewage carries out the equipment of purified treatment, is fit to the various purified treatment that only contain solid impurity sewage.
Background technology
Existing mode at the solid impurity sewage disposal is single, and main sedimentation basin (concentration basin etc.) in every way is for supporting.
All there is following problem in existing various sedimentation basin: at first be that floor space is big, construction cost is high, be not suitable for small-sized manufacturing enterprise and carry out the scale sewage disposal; Next is complicated to sedimentary processing, and floor space is also big, can not in time rationally handle; It three is (concentration basin etc.) complicated operations, needs plant equipment uninterruptedly to carry out cleaning operation.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a cover floor space little, invest to build that cost is low, blowdown is handled reasonable, simple to operate and need not the apparatus for treating sewage that contains solid impurity of exterior mechanical cleaning.
The technical scheme that provides according to invention, the collecting region of solid impurity is set in the bottom of tubular sedimentation device, on this collecting region, be provided with discharge gate, the middle part of tubular sedimentation device is provided with the main decanting zone that is connected with collecting region, internal face in main decanting zone is provided with the anti-swirl pot of plurality of vertical shape, the top of tubular sedimentation device is provided with the overflow decanting zone, in the overflow decanting zone, offer some overflow launders, between the bottom of overflow launder, be provided with the communicating pipe that adjacent overflow launder is communicated with, this communicating pipe is connected with the leakage fluid dram that is arranged on overflow decanting zone outer wall, the entrance point of feed tube links to each other with the sewage pipe in the external world, and the port of export of feed tube is inserted in the main decanting zone.
Collecting region is back taper, is provided with discharge gate in its bottom.The overflow decanting zone is cylindric, and several overflow launders that are arranged at top, overflow decanting zone are respectively concentric and connect together and cylinder that radius progressively increases, and at this moment, feed tube passes the center of overflow decanting zone.Be respectively equipped with the overflow pipe of plurality of vertical shape in each overflow launder cylindraceous, the bottom of overflow launder is passed in the lower end of this overflow pipe.Main decanting zone is cylindric, and the cross section of anti-swirl pot is concentric aplysia punctata, and feed tube is arranged on center, main decanting zone.
Below the outlet of feed tube lower end, be provided with water fender.The drainage tube of feed tube and stabilization pond, grease removal tank joins, and the bottom of stabilization pond is provided with feed pipe, and its top is provided with discharge nozzle, and the below of discharge nozzle is provided with sieve plate and grease removal tank, and sieve plate covers the top of grease removal tank.Drainage tube links to each other with deaeration, and the mozzle of deaeration is communicated with feed tube.
Floor space of the present invention is little, invest to build that cost is low, blowdown is handled reasonable, simple to operate and need not the exterior mechanical cleaning, the solid impurity in the sewage and greasy dirt can be handled totally, reaches discharge standard.

The specific embodiment
As shown in the figure: the collecting region 15 that solid impurity is set in the bottom of tubular sedimentation device, on this collecting region 15, be provided with discharge gate 16, the middle part of tubular sedimentation device is provided with the main decanting zone 9 that is connected with collecting region 15, internal face in main decanting zone 9 is provided with the anti-swirl pot 10 of plurality of vertical shape, the top of tubular sedimentation device is provided with overflow decanting zone 18, in overflow decanting zone 18, offer the overflow launder 11 that some and main decanting zone 9 is communicated with, between the bottom of overflow launder 11, be provided with the communicating pipe 17 that adjacent overflow launder 11 is interconnected, this communicating pipe 17 is connected with the leakage fluid dram 14 that is arranged on overflow decanting zone 18 outer walls, the entrance point of 1 feed tube 8 links to each other with the sewage pipe in the external world, the port of export of feed tube 8 is inserted in the main decanting zone 9, and preferably feed tube 8 inserts in the main decanting zone 9 after passing the center of overflow decanting zone 18.
Collecting region 15 is back taper, is provided with discharge gate 16 in its bottom.Overflow decanting zone 18 is cylindric, and several overflow launders 11 that are provided with in it connecting together and cylinder that radius progressively increases for concentric, and at this moment, feed tube 8 passes the center of overflow decanting zone 18.Be equipped with the overflow pipe 12 of plurality of vertical shape in each overflow launder 11 cylindraceous, this overflow pipe 12 passes the bottom of overflow launder 11, is positioned at the bottom of overflow decanting zone 18.Main decanting zone 9 is cylindric, and the cross section of several anti-swirl pots 10 of its inwall setting is concentric aplysia punctata, and feed tube 8 is arranged on 9 centers, main decanting zone.Below the outlet of feed tube 8 lower ends, be provided with water fender 20.Feed tube 8 joins with the drainage tube 6 of stabilization pond 2, grease removal tank 5, and the bottom of stabilization pond 2 is provided with feed pipe 1, and its top is provided with discharge nozzle 3, and the below of discharge nozzle 3 is provided with sieve plate 4 and grease removal tank 5, and sieve plate 4 covers the top of grease removal tank 5.Drainage tube 6 links to each other with deaeration 7, and the mozzle 60 of deaeration 7 is communicated with feed tube 8.
During work, sewage by feed pipe 1 enter stabilization pond 2 stable after, pass through sieve plate 4 through discharge nozzle 3 overflows, after screening out solid particle in the sewage, sieve plate 4 enters in the grease removal tank 5, the oil slick that will be floated over above the sewage by the oil expeller 5 on grease removal tank 5 tops strikes off, after grease removal tank 5 oil removings, enter in the deaeration 7 by drainage tube 6, stay for some time, so that the air that is mingled in the sewage can be escaped, sewage carries out after the degasification basicly stable, mozzle 60 by deaerating tank 7 bottoms enters in the center feed tube 8 of main system, enter in the main decanting zone 9 by central feed tube 8, a large amount of anti-swirl pots 15 of installing in the main decanting zone 9 can prevent that sewage from forming unsettled eddy flow, sewage are upwards flowed reposefully, during this period, bulk materials in the main decanting zone 9 carries out stable settlement, precipitum enters in the collecting region 15 of taper, and after collecting region 15 inner accumulated arrive certain amount, discharges by discharge gate 16.After the bulk materials sedimentation, the sewage that contains thinner impurity rises up in the slow overflow decanting zone 18 along the passage between the anti-swirl pot 10, upwards introduce in the overflow launder 11 by the overflow pipe 12 in the overflow decanting zone 18, because slowly overflow decanting zone 18 is formed the overflow ducts of overlength by a large amount of overflow pipe 12 and multiple tracks overflow launder 11, overflow flow velocity antipode is slow, in such environment, fine impurities in the sewage can effectively be precipitated, import main decanting zone 9, clear water behind the sedimentation removal of contamination then enters overflow launder 11, after the discharge system that flows to leakage fluid dram 14 communicating pipe 17 of 11 of overflow launders finishes sewage disposal work.
