Description
Technical field:
The invention belongs to solid-liquid precipitated separation technology field, relate to a kind of improvement of water treatment facilities technology.
Background technology:
At present, the water treatment deposition equipment of application, its major defect are that the solids in the sedimentation basin have more leakage at sedimentation basin, and the sedimentation basin delivery turbidity can not further reduce, and deposition efficiency and sedimentation effect are all undesirable.The main cause that causes the problems referred to above is that the removal mechanism of sedimentation basin is the shallow pool theory of precipitation, and its precipitation is removed length and the swash plate spacing (precipitation distance) that ratio mainly relies on sedimentation basin swash plate equipment.The particle certain to character, under swash plate length and the certain situation of precipitation distance, the sedimentation basin load is certain, and the removal ratio of particle has just been determined in the fluid.Improve the efficient of Separation of Solid and Liquid, must set about, introduce new mechanism from the sedimentation function that improves particle.
In the water treatment, depositing reservoir mainly relies on the contact flocculation effect, make solids by the slime layer that suspends, come in contact flocculation with flco wherein, particle is trapped in the slime layer, thereby make particle obtain removing, obtain primary water, but the general hydraulic load of depositing reservoir is lower, mainly be because medicament only mixes and elementary flocculation through simple with former water, the suspension slime layer of just flowing through, the suspension flco of Xing Chenging is loose like this, and volume density is little, want the bigger suspension slime layer of organizator density, must experimental results show that through fairly perfect course of reaction: through the suspension slime layer of improving course of reaction formation bigger volume density can be arranged, its hydraulic load can improve 3 by more conventional depositing reservoir---and 4 times.
Summary of the invention:
Technical problem to be solved by this invention is:
A kind of counter-current contact flocculating settling apparatus is provided, it can utilize the upwards jacking effect of liquid stream and the precipitation of swash plate, form flco particle dynamic suspension district between in swash plate district and rectification section, particle runs foul of each other in the floating zone, cohesion is grown up, and utilizes the solids in contact flocculation and the precipitation principle removal water.
Technical scheme of the present invention is as follows:
Its principle is to introduce contact flocculation mechanism in sedimentation basin, through improving the flco suspension slime layer that organizator density is bigger in sedimentation basin of course of reaction, just can improve the clearance of solid and the hydraulic load of technology.
Be provided with the tilted plate section precipitation plate in sedimentation basin, the bottom of tilted plate section precipitation plate is connected with rectifying section plate, is fixed with speed adjusting plate in rectifying section plate one side.
The current that rectifying section plate and speed adjusting plate constitute in the space jointly flow upward component velocity greater than the component velocity that flows upward in the space of tilted plate section precipitation plate formation.
Rectifying section plate and horizontal plane angle α are 30---150 degree, and tilted plate section precipitation plate and horizontal plane angle β are 30---80 degree.
Be provided with strengthening rib strip at rectifying section plate face and tilted plate section precipitation plate face.
The invention has the beneficial effects as follows:
1, the present invention has the advantage of sloping plate deposition equipment and depositing reservoir concurrently, and the precipitation load can reach 1.5 of conventional equipment---and 2 times, 3 of depositing reservoir---4 times;
2, sedimentation effect is good, and under the suitable situation of dosage, the sedimentation basin water outlet can guarantee below 3NTU;
3, compare with depositing reservoir, form the suspension slime layer easily, at initial operating stage, even do not form the suspension slime layer as yet, because the protective effect of swash plate also can obtain sedimentation basin water outlet preferably;
4, because the acting in conjunction of suspension slime layer and swash plate protection section is all good than swash plate and depositing reservoir to the adaptability of different quality and impact load;
5, owing to utilize the contact flocculation principle, more conventional sedimentation basin is saved medicament, and is stronger to the adaptability of water quality;
6, the heavy mud of sedimentation basin is closely knit, and spoil disposal water is less, but the conserve water resource reduces the spoil disposal operating cost.
Description of drawings:
Fig. 1 is an overall structure cutaway view of the present invention;
Fig. 2 is rectifying section plate of the present invention and speed adjusting plate and tilted plate section precipitation plate partial structurtes figure;
Wherein: the 1st, sedimentation basin pond body, the 2nd, reaction tank, the 3rd, changeover portion, the 4th, sedimentation basin, the 5th, sedimentation basin water distribution tracery wall, the 6th, mud-removing bucket, the 7th, discharge pipeline, the 8th, sedimentation basin water outlet water leg, the 9th, tilted plate section precipitation plate, the 10th, rectifying section plate, the 11st, speed adjusting plate, the 12nd, strengthening rib strip.
The specific embodiment:
Liquid stream upward flow is gone in sedimentation basin, flows out through rectification section, swash plate district.React that perfect particle is precipitated to the swash plate surface according to PRECIPITATION MECHANISM and along sliding to bottom, swash plate district under the swash plate.In bottom, swash plate district and rectification section, particle will be subjected to the effect of resisting and delaying to current, can not be along sliding away equipment under the commutating zone.Have only the particle that particle diameter is big and density is bigger to leave the floating zone, be precipitated to the sedimentation basin bottom and discharge by the effect of bottom liquid stream jacking.
Liquid-solid two-phase mixed liquor through mixing and course of reaction passes through sedimentation basin water distribution section; upward flow is gone into this equipment; flow into the space that swash plate protection section is formed through the space of rectifying section plate and speed adjusting plate composition; solids (flco) are finished contact flocculation and precipitation process betwixt; solids are discharged through the equipment bottom, and pure fluid is flowed out by its upper side.Strengthening rib strip mainly plays a supportive role.In swash plate protection section; solids separate by the gravitational settling effect, along tilted plate section precipitation plate upper surface downward motion, after the effect of resisting and delaying of chance rectification section; go up to moving to precipitating phase and precipitation process taking place once more, can not leave the space that rectification section and swash plate protection section is formed.Great quantity of floc is moved under such effect, and the coacervation process that bumps, and (time is main relevant with the particle concentration in the liquid) forms stable suspension slime layer after a period of time.The particle flco that has only proportion and yardstick to reach certain numerical value can be precipitated to the sedimentation basin bottom by rectification section.In case the suspension slime layer forms, the particle in the liquid stream of this equipment of flowing through will obtain removing by contact flocculation effect and gravitational settling effect, discharge through equipment.
Speed adjusting plate is to be used for controlling the rectifying section plate district to flow upward component velocity, flows upward component velocity greater than the component velocity that flows upward in the space of tilted plate section precipitation plate formation to guarantee the current that rectifying section plate and speed adjusting plate constitute in the space jointly; Only in this way solids (flco) could be finished contact flocculation and precipitation process between rectifying section plate and tilted plate section precipitation plate.
