Beneficial effect
When this system brings into operation, the water after the flocculation that flows into from the perforation tracery wall 24 of sludge blanket metafiltration pool via water inlet storage mud cylindrical tube 2, receive mud storage mud cylindrical tube 1 and enter swash plate (inclined tube) settler. Sludge settling is slipped at swash plate (inclined tube) device and receives in the mud storage mud cylindrical tube 1, and continues to drop to the bottom of conical pipe 3. Along with lengthening conical pipe 3, receipts mud storage mud cylindrical tube 1, the water inlet of running time are store mud cylindrical tube 2 bottoms and be full of by mud, form the mud slime layer. Water after the flocculation that newly enters is by this layer. The alumen ustum that these mud are all linked up by flocculation forms, and has very strong connection and adsorption capacity. When current flow through this layer, some little alumen ustum were adsorbed in the current, and the alumen ustum that is not adsorbed is also because growing up with the collision of flood mud particle, its settling velocity obviously increases, so when flowing through swash plate (inclined tube) device, precipitating sludge quantity increases, effluent quality is become better and better. Water inlet storage mud cylindrical tube 2 is more high with the mud slime layer degree of depth of receiving in the mud storage mud cylindrical tube 1, and mud slime layer packing is more big, and the flow through length of slime layer of its current is more big, and the mud slime layer is more strong to alumen ustum interception capacity in the water. When the mud slime layer reached certain depth, the alumen ustum in the water was held back by the mud slime layer substantially. Reached filter tank water outlet level from the water quality of sludge silt laminar flow water outlet, because mud is held back by the mud slime layer substantially in the water, swash plate (inclined tube) device is ineffective. The mud slime layer degree of depth is increasing, and effluent quality is become better and better. But its resistance is also increasing, and water inlet storage mud cylindrical tube 2 is more big with the water surface elevation difference of receiving mud storage mud cylindrical tube 1. When reaching certain value, this difference in height just automatically starts spoil disposal mechanism. Namely automatically open the electric butterfly valve 22 of spoil disposal main 10. Drained at the mud of receipts mud storage mud pipe 1 perforated sludge discharge pipe more than 9. The autoshutdown electric butterfly valve 22 then, and mud slime layer filtration work is proceeded. The state of above-mentioned spoil disposal process mud slime layer is not affected, so effluent quality can not be subjected to the impact of spoil disposal process. The mud of receiving in the mud storage mud cylindrical tube 1 by repeatedly such spoil disposal thoroughly is updated. Can prevent thoroughly that the sludge corruption phenomenon in the mud body refuse from taking place.
, should be opened to sludge reflux valve 14 certain aperture and start return sludge pump 15 after very short a period of time at opening of device. Being deposited in the mud that concentration is bigger in funnel 12 bottoms and the conical pipe 3 then is transported in the coagulating basin 18. Owing to enter mud in the former water of coagulating basin dosing, add constantly circulating reflux mud, not in the situation of spoil disposal, the sludge concentration in coagulating basin and the sedimentation sludge blanket metafiltration pool all improves constantly at sedimentation sludge blanket metafiltration pool. Sludge settling constantly increases to the amount of funnel 12 in the sedimentation sludge blanket metafiltration pool. The sludge quantity that is back to coagulating basin also constantly increases. When sludge quantity (flowing into the sludge quantity of sludge blanket metafiltration pool) that the sludge quantity that enters coagulating basin (sludge quantity of the former water of dosing adds sludge back flow quantity) equals to flow out from coagulating basin, the sludge concentration of coagulating basin is just constant. The sludge concentration of sludge blanket metafiltration pool is also constant thereupon. When obviously the open degree of sludge reflux valve 14 was more big, the sludge concentration in the system was more high. When sludge concentration was more high in the system, particle collision probability was more big, and flocculating effect is more good in the coagulating basin. It is more closely knit namely to form alumen ustum, and proportion is more big, and little alumen ustum quantity is more few, and larger alumen ustum all is trapped by sludge silt metafiltration pond the time. This shows the treatment effect of this system of returned sludge energy Effective Raise, its disposal ability of Effective Raise.
Advantage of the present invention is as follows:
1, its overanxious effect is better than traditional sand filter.This is because the function that the sand material of sand filter itself does not have connection substantially and adsorbs little alumen ustum, and the mud granule of mud slime layer to be the hydrolysate of flocculant be coupled to, very strong flocculation, absorption property are arranged.So the sludge blanket metafiltration pool interception capacity is better than the traditional tank people, this is an one.It two is that the traditional filtering method is that sedimentation basin and filter tank are provided with respectively.The little alumina blossom particles that sedimentation basin is not held back enters in the process in filter tank broken.Water enters behind the filtering layer at first to such an extent that these alumen ustum that are broken are flocculated again, promptly so-called little flocculation.Alumen ustum through little flocculation could be held back by filtering layer.The present invention combines precipitation and filtering technique, be not only and do not have the broken problem of alumen ustum, and the water after the flocculation will pass through the mud slime layer, it has strengthened flocculation greatly, and the effect of holding back of mud slime layer is better than traditional filter tank again, so its effluent quality obviously is better than traditional filter tank effluent quality.
2, because mud is back to coagulating basin, effectively improve flocculating effect, improved water quality effectively, improved the disposal ability of equipment.
3, have very strong flocculation and adsorption capacity just because of above-mentioned mud slime layer, and the adsorption capacity of returned sludge, so the present invention has tangible joint medicine function.
4, the regular spoil disposal institute's water consumption of sludge blanket metafiltration pool is suitable substantially with common sedimentation basin water loss, has saved the normal sands filter back washing water yield, and both compare the saving water yield and account for 5% of the processing water yield.
5, working stability is suitable for various difficult water quality, as the processing of low-temperature and low turbidity, low turbid high algae, high all kinds of abominable water quality such as turbid.
