In each mud collection mud pit 61, all is furnished with an air-lift device 9.Air-lift device 9 comprises being inserted in carries mud pipe 91, compressed air pipe 94, mud cover 92.Carrying mud pipe 91 is siphunculus, and its lower end is inserted in the mud collection mud pit 61, carries mud pipe 91 upper ends and stretches into the gas on settling section 4 surface and carry in the mud drainage slot 93, carries junction, mud drainage slot 93 bottom with gas and welds fixing.Compressed air pipe 94 depends on the surface of carrying mud pipe 91, stretches into mud collection mud pit 61, near the lower end of carrying mud pipe 91, insert from the outside and carry in the mud pipe 91, and the tube head of compressed air pipe 94 is upwards state in inside.Compressed air pipe 94 mainly is pressurized air to be introduced into from the outside carry mud pipe 91 lower ends, and upwards sprays in inside, causes to carry mud pipe 91 internal liquids and flow, and makes mud up flow from carrying in the mud pipe 91 automatically.Compressed air pipe 94 is provided with SV 99, and the action of SV 99 can be controlled through PLC.Simultaneously can also be in parallel installed with manually-operated gate 910, when maintenance, use manually-operated gate to control.The mud cover 92 of hat is stamped in the upper end of carrying mud pipe 91, prevents to splash when mud from promoting, and through mud cover 92 water conservancy diversion, guides mud to gas to carry in the mud drainage slot 93 smoothly.It is the stainless steel tanks that have constant slope that gas is carried mud drainage slot 93, and gas is carried mud drainage slot 93 and is connected with outside mud transfer pond 10, and mud is drained in the mud transfer pond 10.
Mud in the mud collection mud pit 61 can flow into smoothly and carry in the mud pipe 91 for ease; Be provided with the broken mud pipe 95 of ventilation in the bottom in mud collection mud pit 61; The broken mud pipe 95 of ventilating can pick out from same compressed air source with compressed air pipe 94; The circulating line 96 that is fit to mud collection mud pit 61 hole shapes is formed on the ventilate bottom of broken mud pipe 95, and a plurality of unidirectional air outlet valves 97 are set on circulating line 96.Ventilate and manually-operated gate 98 is set on the broken mud pipe 95; When the mud plate in the dirt collection mud pit 61 is long-pending; Can open manually-operated gate, ventilate broken mud pipe 95 ventilations to the circulating line 96 that is positioned at mud collection mud pit 61, ejection from a plurality of unidirectional air outlet valves 97; Become flexible the mud in mud collection mud pit 61, help mud and flow into smoothly and carry in the mud pipe 91.
Above mud enrichment region 6, be provided with tube settling district 7, tube settling district 7 adopts body oblique placement arranged side by side to form.Body is communicated with up and down, and tubularly can be various several shapes, all can like rectangle, circle, regular hexagon etc.Behind the most of sludge settling of water in the pre precipitation district 5, liter waterborne is through tube settling district 7, and the little alumen ustum of the remnants in the water further precipitates in inclined tube, forms clear water at last.
Above tube settling district 7, be provided with some the finger type water legs of laterally laying 42; Finger type water leg 42 is stainless steel trough body that an end connects clear water canal 8; On cell body, offer some prosopyles 43, the clear water that forms through tube settling district 7 post precipitations rises through entering into finger type water leg 42 in the prosopyle 43, by 42 drainages of finger type water leg to clear water canal 8; Clear water canal 8 lower ends connect rising pipe 81, and clear water is discharged from rising pipe 81.
Need to prove that in addition the mud part in the mud transfer pond 10 is back to mud on the water inlet pipe 21 through reflux pump 12,, get in the mixing pit and mix through with after former water mixes.And the mud of redundance is discharged mud through sludge pump 11.Diving plug-flow stirrer (not shown) is set in 10 bottoms, mud transfer pond, mud is carried out plug-flow stir.
The purification process process of the utility model is: at first, former water gets into from water inlet pipe 21 in company with returned sluge, and flocculation agent adds in water inlet pipe 21 through flocculant concentration pipe 22, together gets in the mixing pit 2 with former water and returned sluge.Fully stir through mixing and blending machine 23 in the mixing pit 2, stir back formation mixing water one and from weir flow canal 31, overflow to flocculation basin 3.
Mixing water one adds pipe 35 in the bottom of flocculation basin 3 through coagulant aids simultaneously and adds coagulant aids after flowing to the flocculation basin bottom through weir flow canal 31, is promoted by flocculation stirrer 32 then and stirs, and forms mixing water two.Mixing water two is flow in the settling section 4 by the weir flow hole 36 of flocculation basin 3 tops again.
When mixing water two gets into settling section 4, at first precipitate, because mud self proportion is heavier through pre precipitation district 5; Through building up to the bottom of settling section 4 behind the pre precipitation district 5, just the mud enrichment region 6, the mud that precipitates of mud enrichment region 6; Scraped to mud collection mud pit 61 by reciprocal mud scraper; Mud in the mud collection mud pit 61 is carried the gas that mud is promoted to above the settling section 4 in the mud drainage slot 93 through air-lift device 9, gets into then in the mud transfer pond 10.Mud part in the mud transfer pond 10 is back in the water inlet pipe 21 through reflux pump 12, forms above-mentioned returned sluge, mixes with former water, gets in the mixing pit 2, and redundance is drained through sludge pump 11.
Simultaneously, mixing water two further precipitates through tilting body through waterborne the floating to tube settling district 7 behind the sludge settling; Form clear water and continue come-up; Refer in the type water leg 42 through prosopyle 43 entering, to clear water canal 8, discharge from rising pipe 81 at last by 42 drainages of finger type water leg.
In the utility model mixing pit 2, flocculation basin 3 are separated with settling section 4, and form rectangular configuration, make whole pond type compact.Establish mud enrichment region 6 in 5 bottoms, pre precipitation district, the reciprocal mud scraper of water lower bottom part is scraped the mud collection mud pit 61 to a side with thickened sludge, with air-lift device 9 thickened sludge is proposed to get into mud transfer pond 10.Partially concd mud in the mud transfer pond 10 flows to mixing pit 2 by blowback, with former water, flocculation agent thorough mixing, forms high density mixed flocculation body, is getting into flocculation basin 3.Add organic polymer coagulant aids PAM in flocculation basin 3 bottoms, to improve the alumen ustum flocculating result.The flocculation stirrer makes alumen ustum be unlikely to deposit flocculation basin bottom, and then gets into settling section 4.Mud enrichment region 6 tops are provided with tube settling district 7, improve surface load, with further reduction delivery turbidity, improve effluent characteristics.
The utility model has been set up air-lift device and mud transfer pond in the middle high-density, thus with the concentration and the quantity of control mud, guarantee the stability and the controllability of operation condition in the process that whole deposition purifies.
The foregoing description only be used to explain inventive concept of the utility model, but not to the qualification of the utility model rights protection allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into the protection domain of the utility model.
