A kind of sedimentation tank, including vertically arranged sedimentation tank body 13, sedimentation tank body 13 is provided with wastewater inlet and clear water output, the inside of described sedimentation tank body sets gradually as settling zone 3 from top to bottom, mud transition region 4, mud extrusion dehydration district 5 and qualified mud district 11, the sludge clearing device 6 of qualified mud in drawing clearly sedimentation tank it is provided with in qualified mud district 11, sludge clearing device 6 includes being located at the mudhole 22 of sedimentation tank body inner bottom part center and qualified mud being pushed to the eccentric scraper plate 21 of mudhole, the sludge output coordinated with mudhole it is externally provided with at sedimentation tank body.Described sedimentation tank body overall structure form is in addition to plain base version, it is also possible to use top be cylindrical shape bottom be the overall structure form of reverse taper shape；Can also use settling zone, top be large diameter cylinder type, sludge solids district be roundlet cylindricality, intermediate sludge transition region be the overall structure form of truncated cone-shaped；Can also be used in combination with conventional conventional precipitation pond (depositing reservoir), the mud discharged with conventional conventional precipitation pond (depositing reservoir) is sent into novel sedimentation tank (depositing reservoir) and carries out Treatment of Sludge, Treatment of Sludge become qualified sludge solids remove, by the original water inlet of water outlet loopback (recovery) to conventional conventional precipitation pond (depositing reservoir).
Described settling zone is equivalent to commonly use the sediment fraction of equipment in the past；Described mud transition region is similar with the bottom sludge part commonly using equipment in the past, it it is the part being specifically used to make sludge settling get off, along with mud precipitates downwards, sludge concentration is gradually increased, when mud sinks to bottom mud transition region, mud loses flowability because moisture content is relatively low, the mud so lost flowability is referred to as " sludge solids ", the sludge solids that the sedimentation tank (depositing reservoir) in the past commonly used uses the devices such as mud scraper to prevent from losing flowability produces, otherwise, mud cannot lean on waterpower to discharge.Such as, the mud scraper of mechanical agitation accelerating purifying pool, all the time operate and the mud divided bottom pond is swept, pool bottom sludge precipitation is not allowed to solidify, otherwise, just it is difficult to be discharged by mud by waterpower once sludge settling solidification, for another example, the cleaning shoe device of radical sedimentation basin, also it is equally to remain operating, the mud that stirring precipitates from settling zone, it is made to keep mobility, to discharge by waterpower, and way of the present utility model is on the contrary, it is then to produce sludge solids by every means, the sludge solids lost flowability precipitated from mud transition region, sink to mud extrusion dehydration district；Described mud extrusion dehydration district is one of key of design, the sludge solids lost flowability precipitated from mud transition region, moisture content is the highest, must continue to remove by its internal moisture, this district is the gravity utilizing upper part sludge solids, the sludge solids of extruding lower part, sludge solids layer above extrudes following sludge blanket as piston, it is similar to and as extruding sponge, the moisture in lower floor's sludge solids is squeezed out, form the mud that moisture content is the lowest, the moisture being extruded out from mud is less than sludge solids proportion because of proportion, upwards emersion return to mud transition region, must there be the highest height in mud extrusion dehydration district, so sludge solids of upper part could produce the biggest pressure to the sludge solids of lower part, moisture in mud could be extruded, reach the purpose of sludge dewatering.Such as, if the sludge solids proportion in mud extrusion dehydration district is when about 1.45 grams/cc, so, the solid coal mud layer of 1 meter high will produce the pressure of 0.0145MPa to lower floor, plus the pressure of the 0.06MPa that the water layer height (height overall is about 6 meters) of settling zone and mud transition region produces, total can produce 0.0145MPa+0.06MPa=
The pressure of 0.0745 MPa.In other words, the sludge solids floor in mud extrusion dehydration district often increases by 1 meter high, and the squeeze pressure that the sludge solids bottom mud extrusion dehydration district is subject to is increased by 0.0145MPa.As a example by water layer total height by settling zone and mud transition region is 6 meters below, the corresponding relation of mud extrusion dehydration district height and squeeze pressure is described:
1m----0.075
MPa
5m----0.133
MPa
10m----0.205
MPa
15m----0.278
MPa
20m----0.350
MPa
Can be seen that from above-mentioned data, in mud extrusion dehydration district, the most down the squeeze pressure suffered by sludge solids is the biggest, the moisture being extruded out is the most, sludge solids moisture content is the lowest, utilize sludge dewatering district internal upper part to divide the action of gravity extruding lower part sludge solids of sludge solids (including settling zone and transition region water), the moisture in lower part sludge solids is extruded, thus reaches the purpose of sludge dewatering.Sludge solids bottom described mud extrusion dehydration district is by after the long extrusion dehydration of sludge solids above, in sludge solids, moisture major part is extruded, when the moisture content of sludge solids low to can with received degree time, it is possible to cleared out, such sludge solids, the most qualified mud.In the intrinsic bottom of sedimentation tank, retain the qualified mud of certain altitude, for preventing above water and underproof mud from surprisingly spilling, calculate according to processing the water yield, how many sludge solids can be produced in a period of time, just periodically the qualified sludge solids of qualified mud district lowermost part correspondence water treating capacity be drawn out clearly.
Described wastewater inlet 1 is located on sedimentation tank body upper part outer wall, to having the vertical guide plate 2 coordinated with wastewater inlet 1 in sedimentation tank body；Be provided with center set tank 15 near center at the top of sedimentation tank body, described clear water output is connected with center set tank 15 by outlet pipe 14.This utility model can also be provided with sewage water inlet pipe 18 at wastewater inlet, and the water side of sewage water inlet pipe 18 is arranged on the intrinsic center of sedimentation tank, to having the vertical sewage guide plate 19 coordinated with sewage water inlet pipe water side in sedimentation tank body；Being provided with water leg 17 in the outer, top of sedimentation tank body, described clear water output is connected with water leg 17 by Graceful water pipe 20.
Described sludge output includes the conveying worm 8 being arranged on below mudhole, conveying worm is provided with mud import and sludge outlet, described mud import is connected by the mudhole of sludge bucket 7 with sedimentation tank body, is provided with sludge carrier pipe road 9 at the sludge outlet of conveying worm.Sludge output can also be drag conveyor import or the material transfer equipment import such as concrete pump entrance or piston type delivery pump import.It is provided with sludge outlet in the outer end in sludge carrier pipe road and closes end cap 10.After sludge solids exports, sludge solids can be extruded by internal gravity by conveying equipment and conveyance conduit, so the design has installed one section of sludge carrier pipe road and the sludge outlet closedown end cap of suitable length additional in the outlet of sludge solids conveying equipment.After sludge solids conveying equipment is out of service, sludge outlet is closed end cap and is automatically switched off, and the sludge solids at this moment retained in sludge carrier pipe road is the formation of a sludge solids post, and outlet conduit " is clogged " by this sludge solids post just as one " bottle stopper ".Sludge outlet closes end cap the most again to this " bottle stopper " (i.e. sludge solids post) pressure, prevents this " bottle stopper " (i.e. sludge solids post) to be extruded by internal pressure.This prevents internal mud to be extruded by internal pressure by the passage of sludge solids conveying equipment.End cap can also be closed without sludge outlet, sludge carrier pipe road can be extended upward, make the pressure pressure more than or equal to device interior of pipeline internal solid mud, be so also possible to prevent internal mud and extruded by internal pressure by sludge solids conveying equipment passage.Valve can also be installed additional in the outlet of sludge solids conveying equipment, open during conveying equipment work, close during stopping, equally, also can prevent internal mud from being extruded by internal pressure by sludge solids conveying equipment passage.According to different needs, use the different methods preventing internal mud from being extruded by internal pressure by sludge solids conveying equipment passage.
It is fixed with towards eccentric scraper plate direction of rotation at the top of eccentric scraper plate and cuts mud plate 26 every mud.Described cut mud plate 26 and eccentric scraper plate vertical (according to different needs, it is also possible to the most vertical) the front being welded on scraper plate rotary-top direction every mud.When eccentric scraper plate rotates and scrapes mud, mud plate is cut in front sludge solids is first cut in scraper plate front every mud, separate cutting the sludge solids above mud plate every mud and the sludge solids of top is held, scraper plate is made the most only to scrape the sludge solids rotating front one blade height, will not sludge solids above scraper plate.So scraper plate often rotates a circle, will be by the sludge solids Ceng Guaru pond bottom centre mudhole of a blade height (height calculated by a scraper plate).When scraper plate rotates continuously, will by the sludge solids in qualified mud district from bottom Gua Ru pond bottom centre mudhole the most continuously.So, the mud in qualified mud district (including mud extrusion dehydration district) declines the most equably, will not form the logical hole of " funnel " shape, and the sewage on top would not be through the entrance bottom, logical hole of " funnel " shape.
Described eccentric scraper plate includes that periphery is scraped mud section 23, middle transition section 24 and mud is pushed to the centre pilot section 25 of mudhole.Described periphery is scraped mud section 23, middle transition section 24 and centre pilot section 25 and is arranged continuously.The intersegmental disconnected setting of mud section, middle transition section and centre pilot is scraped in described periphery.Described eccentric scraper plate is that the rectangular slab of the setting not passing through pond centrage around the rotation of pond centrage is (according to different needs, may not be flat board rectangle, can be the other shapes of plates such as arc), when scraper plate rotates around pond centrage, the horizontal line of the point on any point and same level upper storage reservoir centrage on scraper plate, with the angle of eccentric scraper plate both greater than (or being equal to) 90 degree, such scraper plate just pushes the sludge solids in rotation front to mudhole.Described eccentric scraper plate every section can also divide multilamellar to install not all on a horizontal plane as required up and down.Utilize eccentric scraper plate by sludge solids in bottom layer by layer bottom pond each position " equably " scrape the mudhole of Chi Dibuzhongxinchu, in other words, being exactly scraper plate every revolution, the mud in qualified mud district the most integrally declines the height of an eccentric scraper plate.As the height that qualified mud district (including mud extrusion dehydration district) each position declines is necessary, otherwise, will result in the logical hole declining fast position formation " funnel " shape, the sewage on top will pass through bottom the entrance pond, logical hole of " funnel " shape.
