Detailed description of the invention
Be below specific embodiments of the invention, technical scheme of the present invention is described further, but protection model of the present inventionEnclose and be not limited to these embodiment. Every do not deviate from the change of the present invention design or be equal to substitute include at protection model of the present inventionWithin enclosing.
As shown in Figure 1, novel high-density sludge blanket clarifier, comprises water inlet pipe 1, clarifying chamber 3, the first reative cell 5, second anti-Answer chamber 6, outlet pipe 7 and mud return line 18, the first reative cell positions 5 in the middle part of the second reative cell 6, the second reative cell position6 in the middle part of clarifying chamber 3, and the first reative cell 5, the second reative cell 6, clarifying chamber 3 are connected by quill 16, the first reactionIn indoor 5 quill 16, being connected with paddle 4, the second reative cell 6 bottoms and quill 16 connecting portions is provided with first anti-Answer extending 19, the first reaction extending 19 bottoms to be arranged with conically shaped 20, large mud scraper is fixed in the lower end of conically shaped 20On 23, large mud scraper 23 is connected on mandrel 22, and conically shaped 20 can promote or decline with large mud scraper 23, when bottom depositionWhen thicker, can promote large mud scraper 23 and successively scrape mud; Conically shaped 20 belows are provided with discharge pipeline 24, water inlet pipe 1 and sludge refluxPipe 18 respectively level passes into the first reative cell 5, and 3 tops, clarifying chamber are provided with chemical feed pipe 11, liquid level transmits mouth 12, emptying samplingMouthfuls 13 and loophole 14, chemical feed pipe 11 bottoms are communicated to the first reative cell 5 bottoms, clarifying chamber's 3 sidewalls be provided with outlet pipe 7,Sampling station 9 and temperature-measuring port 17, sampling station 9 is connected with the sample tap 2 in clarifying chamber 3, and the top of clarifying chamber 3 is provided with overflow pipe15, the bottom of clarifying chamber 3 is provided with evacuated tube 10 and manhole 21.
Particularly, described water inlet pipe 1 is all tangentially connected with the first reative cell 5 barrel annulars with mud return line 18.
Particularly, backflow gap is arranged at described conically shaped 20 bottoms, and react with first by the gap between paddle 4 in backflow gapChamber connects circulation in 5 logical formation, and mud return line 18 is communicated with formation outer circulation with the first reative cell 5, and interior circulation is tied mutually with outer circulationClose the large sludge reflux amount that realizes, reflux ratio is 5-10 times.
Particularly, described large mud scraper 23 moves up and down with mandrel 22. In the time that bottom deposition is thicker, can promotes greatly and scrape on the one handMud rake 23 is successively scraped mud; Increase on the other hand gap, be beneficial in conically shaped and loop.
Particularly, the bottom of described the second reative cell 6 is lower than the bottom of the first reative cell 5.
Particularly, 3 outsides, described clarifying chamber are provided with heat-insulation layer 8.
Sewage tangentially enters the first reative cell through water inlet pipe by annular, mix with clarifying chamber's backflow body refuse at this and complete medicament withThe hybrid reaction process of water. It is de-steady after positively charged coagulant ionization after electronegative suspended particulate and hydrolysis in former water,Between particle, by effects such as collision, adsorption, Van der Waals forces, interosculate and become large. Due to the castering action of paddle,The water of carrying active sludge after mixing secretly is risen to the second reative cell from the first reative cell, complete in this course contact flocculation.At the second reative cell, the current of powerful rotation are rectified, and form the slight stream of carrying, thereby flow velocity anticlimax are conducive to small flocculent gelGrowing up also and the backflow body refuse particle suspending adhesion of grain. Arrive clarifying chamber through the second reative cell bottom, due to clarifying chamber's areaVery large, slow down slowly from the second reative cell water velocity out. The flocculation body refuse particle of growing up under the effect of gravity, gradually underSink and separate with water, the top of separation chamber becomes clear water zone, and clear water upwards enters clear water reserviors by outlet pipe person who lives in exile water leg. SeparateThe bottom of chamber is suspension slime layer, and the body refuse of a sinking part flows into the first reative cell again along the backflow gap at the cone end, again withFormer water carries out contact flocculation reaction. Another part enters body refuse concentration basin by discharge pipeline, discharges outside pond after being concentrated into finite concentration.
The first reative cell, the second reative cell, clarifying chamber, in same pond, have saved occupation of land space greatly, and pond body mechanism can be steelStructure, also can be xoncrete structure. Under chemical feed pipe, be terminated at the first reative cell bottom, be conducive to the medicament such as coagulant, flocculantWith fully mixing of sewage. Shut down maintenance for preventing tank boil-overs and being convenient to, overflow pipe and evacuated tube are set. The power transmission shaft of mixer isCoaxial design: quill is sheathed on outside mandrel, quill connects paddle, and mandrel connects large mud scraper.
This depositing reservoir the second reative cell is flocculation zone, needs certain time of staying herein, general 20-30min. The second reative cellShould be lower than the first reative cell, so that underflow is from the radial inflow settling section in depositing reservoir flocculation zone bottom, solve the too high underflow meeting of urceolusImpact the problem of sludge blanket impact effect.
Depositing reservoir adopts large sludge circulation amount, i.e. conically shaped-Nei circulation+mud return line-outer circulation mode, makes body refuse increase in density(concentration of hydraulic mixture > 5%wt) to form stratiform sedimentation (crowded sedimentation). This kind of sedimentation, sludge density is substantially the same from top to bottom.Because sludge concentration is high, sludge blanket plays the effect of filtering ponds, and effluent characteristics is better than general depositing reservoir.
The present invention is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present invention, everyThere is identical or close technical scheme with the present invention, within all falling into protection scope of the present invention.
Technology, shape, structure part that the present invention does not describe in detail are known technology.
