Useful effect
When this system begins to move, flow into from the perforation tracery wall 24 of sludge blanket metafiltration pool Water after the flocculation enters swash plate via water inlet storage mud cylindrical tube 2, receipts mud storage mud cylindrical tube 1 (inclined tube) settler. Sludge settling is slipped to receipts mud at swash plate (inclined tube) device Store in the mud cylindrical tube 1, and continue to drop to the bottom of taper pipe 3. Along with the operation time Lengthening taper pipe 3, receive mud storage mud cylindrical tube 1, water inlet storage mud cylindrical tube 2 bottom quilts Mud is full of, and forms 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, have very strong connection with The absorption ability. When current flow through this layer, some little alumen ustum were adsorbed in the current, not by Also because growing up with the collision of flood mud particle, its settling velocity obviously increases the alumen ustum of absorption, institute When installing to flow through swash plate (inclined tube), precipitating sludge quantity increases, and effluent quality more comes More good. Water inlet storage mud cylindrical tube 2 is dark with the mud slime layer of receiving in the mud storage mud cylindrical tube 1 Spend more highly, mud slime layer packing is more big, and the flow through length of slime layer of its current is more big, The mud slime layer is more strong to alumen ustum interception capacity in the water. When the mud slime layer reaches a depthkeeping When spending, the alumen ustum in the water is held back by the mud slime layer substantially. From the water outlet of mud slag laminar flow Water quality reached filter tank water outlet level since water in mud substantially by mud slime layer institute Hold back, swash plate (inclined tube) device is ineffective. The mud slime layer degree of depth is increasing, Effluent quality is become better and better. But its resistance is also increasing, water inlet storage mud cylindrical tube 2 with The water surface elevation difference of receiving mud storage mud cylindrical tube 1 is more big. When this difference in height reaches certain value Just automatically start sludge discharging machine system. The electric butterfly valve 22 of mud main 10 is arranged in i.e. automatic unlatching. Drained at the mud of receipts mud storage mud pipe 1 perforated sludge discharge pipe more than 9. Autoshutdown then Electric butterfly valve 22, mud slime layer filtration work is proceeded. Above-mentioned row's mud process dirt The state of mud slime layer is not affected, so effluent quality can the row's of being subjected to mud The impact of process. Thorough by the mud that repeatedly such row's mud is received in the mud storage mud cylindrical tube 1 The end, be updated. Can prevent thoroughly that the sludge corruption phenomenon in the mud mud slag from taking place.
, should be opened to sludge reflux valve 14 necessarily after very short one period at opening of device Aperture also starts backflow sludge pump 15. Be deposited in funnel 12 bottoms and the taper pipe 3 dense Spending bigger mud then is transported in the coagulation pond 18. Owing to enter the former water of coagulation pond dosing In mud, add constantly circulating reflux mud, at sedimentation sludge blanket metafiltration pool Do not arrange in the situation of mud, the mud concentration in coagulation pond and the sedimentation sludge blanket metafiltration pool all Improve constantly. Sludge settling constantly increases to the amount of funnel 12 in the sedimentation sludge blanket metafiltration pool Add. The sludge quantity that is back to the coagulation pond also constantly increases. When the sludge quantity that enters the coagulation pond (sludge quantity of the former water of dosing adds sludge back flow quantity) equals from the mud of coagulation pond outflow During amount (flowing into the sludge quantity of sludge blanket metafiltration pool), the mud concentration in coagulation pond is just permanent Fixed. The mud concentration of sludge blanket metafiltration pool is also constant thereupon. Obvious sludge reflux When the open degree of valve 14 was more big, the mud concentration in the system was more high. Mud concentration in the system When more high, particle collision probability is more big, and flocculating effect is more good in the coagulation pond. Namely form alum Hua Yue is closely knit, and proportion is more big, and little alumen ustum quantity is more few, and larger alumen ustum is passing through mud The slag metafiltration all is trapped during the pond. This shows locating of backflow mud energy this system of Effective Raise The reason effect, 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.
