The sludge suspension layer having high concentration is formed in the mud funnel device. Hnece the new product drastically improves the overflow quality and the water quantity. The overflow quality is 3 times than the common device, and it is stable, suitable for all difficult treating water quality.
Description
The present invention belongs to solid, liquid gravity separation process and device.Be mainly used in fields such as water treatment, chemical industry.
The present invention is by inclined plate sedimentation device I, sludge funnel device II, sludge funnel carriage 5, and swash plate carriage 4, sedimentation basin body 6, mud-removing bucket 7, discharge pipeline 8, perforation tracery wall 9, outlet pipe 10 are formed.
It is characterized in that: its inclined plate sedimentation device is supported on the swash plate carriage, be by a plurality of suitable for reading big, young down below it, it is shaped as the sludge funnel device that square, rectangle, polygon sludge funnel are formed, this device is supported on the sludge funnel device carriage, when sludge funnel device height hour, the swash plate carriage can remove, and inclined plate sedimentation device directly is supported on the sludge funnel device.
Usually the solid, liquid separator is a sloping plate deposition equipment.This is connected and fixed with parallel downward-sloping supporting rib by numerous squares dull and stereotyped (swash plate) of tilting of being parallel to each other, and the swash plate module of formation forms.Water or other liquid flow from bottom to top along swash plate and rib formation ramp way, and the solid particle vertical is deposited on the swash plate, and slides along swash plate, and clear water is flowed out by the swash plate upper end.This equipment has only the precipitation function, the function of not flocculating.
Water treatment field scientist and scholar want to utilize the precipitating sludge of sedimentation basin always for a long time, make it participate in flocculation reaction, and this has two benefits.The first can make the alumina blossom particles concentration in the flocculation process increase substantially, and forms the body refuse superposed layer of high concentration.When the former water of dosing passed through this layer, the mud of alumen ustum in the water and suspension slime layer collision probability had increased significantly.A lot of granule alumen ustum are caught by this layer particle, and the particle that is not captured then flows in the next technological process sedimentation basin.This part alumina blossom particles is owing to collide to combine also with mud granule by the suspended sludge slag blanket time and obviously magnify, and its settling velocity obviously improves.Therefore can increase substantially the effluent quality and the water yield of sedimentation basin.It two is because the existence of high concentration body refuse superposed layer makes sedimentation basin work more stable, changes suddenly when adding dose and can not in time change at raw water turbidity, and the particularly high turbid time, the sedimentation basin water outlet can be not influenced.If common sloping plate deposition effluent quality will anxious poly-the deterioration.It three is because the existence of high concentration body refuse superposed layer, and in various extremely difficult water quality such as low temperature and low turbidity water, high muddy water, the high muddy water of low temperature, low turbid high algae water period, the treatment effect of sedimentation basin and effluent quality and the water yield all can be guaranteed.It four is because the mud of high concentration body refuse superposed layer has very strong adsorption capacity, so the function of obvious saving medicament is arranged.
This shows that making the mud of sedimentation basin participate in flocculation reaction is very science, thought very cleverly.But realize that this idea difficulty is very big,, and then enter sedimentation basin because water is to be introduced into flocculation tank.Two kinds of technologies have been addressed this problem at present.The one, mechanical accelerating purifying pool technology, the 2nd, high concentration flocculation sediment pool process.The former basic thought is the mud mechanical lifting at the bottom of the sedimentation basin, makes its circulation and participates in flocculation reaction.The latter concentrates the back to sedimentation basin mud to fail back flocculation, sedimentation basin with pump.The shortcoming of these two kinds of methods is: the one precipitating sludge is through after the mechanical agitation, and some mud alumina blossom particles are damaged, and certainly lead to some littler alumen ustum, and this has just seriously influenced the treatment effect of suspension slime layer; It two is complex process equipment, and investment is big.
The present invention is provided with a plurality of sludge funnels under inclined plate sedimentation device.The mud that slides from swash plate directly falls into sludge funnel, forms the body refuse superposed layer of high concentration therein.When entering water after the flocculation reaction of sedimentation basin and flowing into sludge funnel, pass the body refuse superposed layer from the below.Because the mud of this layer was not subjected to mechanical disturbance, keep the original form of mud, there is not the little alumina blossom particles that forms after the fragmentation of mud alumen ustum, its absorption, collision flocculation are optimal.
Beneficial effect
The mud that drops on the swash plate is slipped in the sludge funnel.Because sludge funnel end opening size is far smaller than sludge funnel size suitable for reading, thus the water after the flocculation reaction when the sludge funnel end opening flows into, flow velocity is far longer than the speed of its sludge funnel outflow suitable for reading.Because its end opening water inlet flow velocity is very big, and the mud that falls from sludge funnel is produced very strong jacking, some heavy mud flow out from sludge bucket, and light mud is then stayed in the sludge funnel.Mud in inclined plate sedimentation device under the precipitation is continuously to slide, and always some light mud is stayed in the sludge funnel, so the sludge concentration in the sludge funnel is in continuous increase.Because mud decrease speed heavy in the sludge funnel is big, light mud decrease speed is little, so under the situation of high concentration sludge, the collision probability of light, heavy mud has increased considerably, the mud yardstick is constantly grown up, and the mud of growing up flows out from sludge funnel again.When the mud in entering sludge funnel equated with the mud that flows out from sludge funnel, the concentration of mud then kept constant in the sludge funnel.From the inclined plate sedimentation device constant required time of sludge concentration the sludge funnel that brings into operation, with the size of sludge concentration size, sludge funnel in the sludge funnel and the sludge funnel end opening is large and small decides.The more little required time of big more its end opening size of sludge funnel is long more.Sludge concentration can decide with the upper and lower open area ratio of sludge funnel in the sludge funnel.Mud can reach very high concentration in the sludge funnel.Just because of the sludge funnel sludge concentration is very high, so in sludge funnel, form the body refuse superposed layer of high concentration.Water after the flocculation reaction will pass the body refuse superposed layer from the sludge funnel inlet when entering.Most granule alumen ustum in the water are caught by mud granule, or length flow in the inclined plate sedimentation device on top to enough big yardstick.The effluent quality and the water yield of inclined plate sedimentation device have so just been improved greatly.Its improvement degree then depends on sludge concentration in the sludge funnel.Should be noted that sludge funnel is high more, the slime layer in the sludge funnel is stable more.Sludge funnel hour, the suspension slime layer in the sludge from sedimentation tank process in the sludge funnel is destroyed, and its spoil disposal rear overhang mud scum slag blanket forms also very fast certainly.Though this situation device is in unstable kind work down, after the suspension slime layer formed, its effluent quality and the water yield obviously improved.Sludge funnel is high more, and the sedimentation basin height is big more, but the work of body refuse superposed layer is stable more, is not destroyed in the time of can reaching sludge from sedimentation tank.Its disposal ability is more than 3 times of common inclined plate sedimentation device.
