Abstract
The invention relates to a multilayer flat unit combined sedimentation basin technology which is aimed at city sewage treatment and is also used for feedwater treatment and industrial waste water treatment. The technology is characterized in that a plurality of circle flats (having mud scrapers) are overlapped and combined to form a multilayer flat unit, and a plurality of the multilayer flat units are disposed in a settling section of a horizontal flow sedimentation tank. The units are shelved on a support and the support supports on the tank walls and the galleries. The plates in the units are disposed on the framework of the units. The mud scrapers are fixed to a center transmission shaft. A sedimentation tank chain-type mud scraper is disposed in a condensation section at the bottom of the sedimentation tank. If the sedimentation tank is too wide, the condensation section should be divided into a plurality of narrow vertical galleries, and each of the narrow vertical galleries is provided with a sedimentation tank mud scraper. The technology provided by the invention is advantageous in that the surface waterpower burden of the sedimentation tank is decreased to be a fraction of the original surface waterpower burden, thereby facilitating maintenance of system high-density activated sludge, improving mud-water separation effects, improving water outlet quality and saving floor space of the sedimentation tank.
Description
Technical field
The present invention relates to a kind of sedimentation basin technology of utilizing the multi-layer planar unit combination to form, specially at municipal sewage treatment, also can be used for to water treatment and Industrial Wastewater Treatment, have the advantages that in sedimentation basin, to install a plurality of multi-layer planars unit (band mud scraper) additional, make the hydraulic surface loading of sedimentation basin be reduced to youngster/one of former sedimentation basin hydraulic surface loading, favourable fourth improves the mud-water separation effect, improve effluent quality, and keep system's high-concentration activated sludge, the floor space of significantly saving sedimentation basin.
Background technology
The high-concentration activated sludge method has extremely excellent disposal ability, but requires the low sedimentation basin of hydraulic surface loading, namely requires desilting area big.The sedimentation basin area is more big, and then its hydraulic surface loading is more low, and sedimentation effect is more good, and the system sludge concentration that can keep is more high, helps to improve the disposal ability of entire sewage treatment system.
Sedimentation basin is the structures of floor space maximum in the sewage treatment plant, save sewage treatment plant's floor space, and sedimentation basin stands in the breach.
Traditional bilayer or multilayer sedimentation basin, be sedimentation basin is divided into two or more, be piled up, though can significantly save floor occupying area, structure and process equipment are had relatively high expectations, so cost is higher, and be subjected to the restriction of technology and structure, floor height is difficult to reduce, and makes the number of plies limited, and the floor space of saving is limited.
Inclined-plate clarifying basin installs swash plate additional in sedimentation basin, utilize gravity to get rid of mud, also belong to a kind of multilayer sedimentation basin, in giving water treatment and Industrial Wastewater Treatment, obtained extensive use, but in municipal sewage treatment, because contained nutriment is many in the sewage, make raised growth biomembrane and algae on the swash plate, cause obstruction, it can not normally be moved, so in municipal sewage treatment, be difficult to all the time adopt.
Summary of the invention
The objective of the invention is, above-mentioned defective at traditional bilayer or multilayer sedimentation basin and inclined-plate clarifying basin, improved, invent a kind of sedimentation basin simple, nonclogging, that save land, low hydraulic surface loading, be used for municipal sewage treatment, give water treatment and Industrial Wastewater Treatment, especially for the high-concentration activated sludge method.
The technical solution used in the present invention is:
Adopt horizontal sedimentation tank pond type, in the settling section of sedimentation basin top, put into a plurality of multi-layer planars unit, but the front end inhalant region of sedimentation basin and rear end exhalant region should not be put into all;
The multi-layer planar unit is shelved on the support, can from sedimentation basin, take out separately, and with convenient maintenance, after a small amount of multi-layer planar unit takes out, overall sedimentation effect that can the appreciable impact sedimentation basin;
Sedimentation basin chain type mud scraper is set in the enrichment region of sedimentation basin bottom, if horizontal sedimentation tank is wideer, then enrichment region should be separated into several narrower vertical gallerys, and the sedimentation basin mud scraper is set respectively;
Shelve the support of multi-layer planar unit, can be supported on pool wall and the gallery;
The multi-layer planar unit is made up of multi-layer planar, and each layer flat board is fixed on the framework of unit, and mud equipment is scraped in each layer flat board and rotation thereof, can dismantle and come, with convenient maintenance, by advancing people's maintenance between the fourth flat board, so spacing can greatly reduce, be convenient to install more multi-layered flat board;
Each layer flat board in the multi-layer planar unit all installs the center transmission rotation mud scraper (being fixed on the power transmission shaft of center) for this flat board service additional, when striking off mud, thoroughly eliminates the blockage problem that biomembrane and algal grown cause;
Dull and stereotyped adopt circularly, plate edge upwarps to prevent that mud from overflowing, and dull and stereotyped center drilling is in order to discharge mud downwards, and holds the center power transmission shaft, and is dull and stereotyped unsuitable excessive, in order to avoid need add the massive plate spacing because of structure;
Motor and transmission device are installed on the superiors' framework of multi-layer planar unit, are driven the center power transmission shaft, thereby drive the mud scraper of each layer;
Because numerous flat boards adds sedimentation basin, make total desilting area several times of sedimentation basin increase, can significantly reduce the sedimentation basin hydraulic surface loading, thereby be conducive to keep system's high-concentration activated sludge, and improve sedimentation effect, save floor occupying area.
Mixed liquor enters sedimentation basin, and precipitation process begins to carry out.In case mixed liquor enters the multi-layer planar unit in the sedimentation basin, precipitation process is reinforced.Mixed liquor enters next unit after flowing out from a unit again, repeats the reinforced deposition process, finally discharges from the sedimentation basin effluent weir until clear water.Sludge settling in the unit is shifted onto dull and stereotyped center by mud scraper again on flat board, drop to enrichment region, and last precipitated pond mud scraper is shifted bucket onto, discharges outside the sedimentation basin.
The beneficial effect that the present invention adopts is, sedimentation basin is because numerous flat board addings, its total desilting area increases several times, and its hydraulic surface loading is reduced to original part, is example with multi-layer planar unit combination sedimentation basin shown in the drawings, its desilting area is 3.44 times of former sedimentation basin, hydraulic surface loading is 29% of former sedimentation basin only, is conducive to keep system's high-concentration activated sludge, and improves the mud-water separation effect, improve effluent quality, the floor space of significantly saving sedimentation basin.
