The specific embodiment
Below in conjunction with preferred embodiment, details are as follows to the specific embodiment that provides according to the utility model: see accompanying drawing for details, a kind of upward current suspended filter material filter pool 1 comprises former pool 6, water distribution zone 10,2 four functional areas of filtering area 4 and clear water pool.Said upward current suspended filter material filter pool is provided with water distribution system, agitated rinse system, recoil water discharge system and liquid level indication mechanism.Said water distribution system is made up of with water inlet control valve 7 perforation water distributor 9; Said agitated rinse system is made up of agitated rinse pipe 8 and agitated rinse control valve 5; Said recoil water discharge system is made up of recoil water discharge spout 12 and recoil water discharge spout 11; Said liquid level indication mechanism is made up of liquid level indicator tube 14, block 13,16 and simulation filter material layer 15.Said water inlet control valve 7, agitated rinse control valve 5 and recoil water discharge spout 11 adopt electronic or pneumatic control; Valve and caliber size are decided according to water yield scale; Said liquid level indicator tube adopts the transparent organic glass pipe, in establish with the filter tank in the filter material layer simulation filter material layer that is of uniform thickness, the lucite tube bottom is provided with block 13 and is communicated with the filter tank, open topped, vertical installation.
As shown in Figure 1, when said upward current suspended filter material filter pool filtered, agitated rinse control valve 5 was closed with recoil water discharge spout 11; And water inlet control valve 7 is in opening, and this moment, sewage was from former pool 6, by the perforation water distributor 9 entering filter tanks of bottom, filter tank; And the filtering area 4 through constituting from bottom to top by the lightweight suspension filtrate; The lightweight suspension filter is held back by the filter of installing on anti-floating filter plate 17 and the filter plate 3, and sewage is through filtering area 4, after water pollutant is trapped; Get into clear water zone 2 through filter 3, collect the back by effluent trough 18 at last and discharge.
As shown in Figure 2; Said upward current suspended filter material filter pool exists two processes when recoil: at first be that recoil water discharge spout 11 is opened with agitated rinse control valve 5; Water inlet control valve 7 is closed simultaneously, and the liquid level in the filter tank descends fast, and the suspended filter material layer moves down with liquid level; And through stirring the first time of agitated rinse pipe 8, the water that recoils this moment is discharged through recoil water discharge spout 11; When the liquid level in the filter tank was reduced to design load, the recoil water discharge spout was closed, and the liquid level in the filter tank begins to rise; And the suspended filter material layer rises with the liquid level in the filter tank; And through stirring the second time of agitated rinse pipe 8, when liquid level was higher than the top of anti-floating filter plate 17, recoil finished; Close recoil water discharge spout 11 this moment, open water inlet control valve 7 and recover filter process.
The filtration of said upward current suspended filter material filter pool and backwash process all can reflect through the liquid level indication mechanism.Liquid level indicator tube 14 bottoms of liquid level indication mechanism are communicated with the filter tank and vertical installation, and when work in the filter tank, simulation filter material layer 15 can accurately be simulated the running status in filter tank.
Operation principle:
The sieving effect.Water inlet control valve is opened during normal filtration, and the agitated rinse control valve is in closed condition with the recoil water discharge spout.When former water is flowed through filter material layer from bottom to top; Particle diameter at first is trapped within the filtrate of bottom greater than the suspended particulate substance in filtering layer space; Make that the space of bottom filtrate is more and more littler, form one deck gradually by being trapped the filter membrane that thing constitutes, and play the filtration of " dirt is cut on the top layer ".Because this filtration is carried out at filter material surface, so be also referred to as surface filtration.
Because " dirt is cut on the top layer " phenomenon of sieving effect can make filtration resistance increase, stop up the filter tank when serious, in making, the dirty effect of receiving of upper strata filtrate is not in full use.Therefore, upward current suspended filter material filter pool is according to different Inlet and outlet water water quality requirements, adopts the filtrate of different-grain diameter to carry out the grade separation ratio, filtering layer along the direction of current from bottom to top particle diameter reduce, weakened " dirt is cut on the top layer " effect, improved the water environment capacity of filter material layer.
Adhesive attraction.The huge specific area of upward current suspended filter material filter pool EPS light filter material makes it that suspended particulate is had tangible adhesive attraction.Under the interaction and some chemical bond and particular chemical suction-operated of Van der Waals force, electrostatic force, with filter material surface near to or in contact with particle will be sticked on the filter material surface.Adhesion process also is accompanied by the bridging action of flocculation particle simultaneously, is called contact flocculation.Adhesive attraction is a kind of physics chemical action, and the power of adhesive attraction depends primarily on the Surface Physical Chemistry character of suspended filter material in filtrate and the water.
Upward current suspended filter material filter pool is mainly city sewage deep treatment and researches and develops, and its main filtering object is an activated sludge residual in the second pond water outlet, so its filtration act as the master with the surface filtration of sieving form.
The recoil process
Open when the recoil water discharge spout, when the clear water in filter tank hurtled down through the light filter material layer from top to bottom, current produced the drag force effect to filtering material particle; Meanwhile, filtering material particle has shielding action to the drag force that current produced, and this shielding action makes the suffered drag force of basecoat particle maximum, and the suffered drag force of the superiors is minimum.Therefore, when water velocity during greater than fluidizing velocity, always the basecoat filtrate is draged earlier and is sunk; When the basecoat filtrate breaks away from filter material layer integral body; One deck filtrate that is positioned at above it becomes basecoat, and therefore suffered drag force is maximum, is and then draged to sink; So in proper order, till the complete fluidisation of whole filter material layer.
Fluosolids in the filtrate equal diameters is inner, owing in existing repulsive force effect between particle on water (flow) direction and its vertical direction, make the clear distance between filtering material particle must keep equal.Like this, in backwash process, the phase mutual friction between filtering material particle is limited with the effect of collision each other, removes the shearing action that the suspended solid that is bonded on the light filter material mainly leans on current.
Upward current suspended filter material filter pool is provided with the agitated rinse pipe in the filter material layer bottom, evenly arranges and level stirring hole in a certain angle on the pipe, and the flow shear on the horizontal direction is provided, and the probability of mutual collision and friction improves repercussion effect between the increase filtering material particle.
Main feature:
The lightweight suspension filtrate, water environment capacity is strong.Upward current suspended filter material filter pool adopts EPS lightweight suspension filtrate, and this filtrate proportion is littler than water, in the whole process of filtering and recoiling, remains at the suspended state in the water.Water inlet through the suspended filter material layer, is trapped in the filtering layer bottom with the suspension in the sewage from bottom to top, and filter back water is collected discharging through water leg from the upper strata, filter tank.
The filtrate grating guarantees the water outlet effect.The EPS lightweight suspension filtrate that upward current suspended filter material filter pool adopts requires to carry out the grade separation ratio according to flooded condition and water outlet in design, makes it under different particle diameter of filter medium and proportion, forms the classification filtering layer.On the direction of current, the filtrate diameter reduces last, has reduced the filtration of " dirt is cut on the top layer ", has given full play to the water environment capacity of deep layer filtrate, has improved the utilization rate and a section dirty effect of filtrate.
Automatically controlled filter and recoil process are simple to operate.Upward current suspended filter material filter pool relies on water level pressure reduction to make sewage from bottom to top through the suspended filter material layer, and along with the prolongation of filtration time, the holding filth capacity of filter material layer increases, and it is increasing to overcome the required liquid level pressure reduction of hydraulic loss.The utility model backwash is stirred valve, water intaking valve and recoil water discharge spout and is electronic.When the liquid level difference between water inlet liquid level and water outlet liquid level increased to a certain degree, recoil was automatically realized in the filter tank.Also can set the recoil cycle in addition, fully guarantee the water outlet effect according to actual water quality situation.Whole filtration and recoil process need not manual intervention, and be simple to operate.
Water inlet agitated rinse+water outlet gravity recoil need not power-equipment.When upward current suspended filter material filter pool recoiled, the filter tank stopped to produce water,, changed into by the agitated rinse pipe and got into the filtering layer bottom by getting into the bottom, filter tank through the former water of the switching of valve, and filter material layer is carried out disturbance; Simultaneously, because of the backwashing water drain valve is opened, let out under the clear water layer on filtering layer top is quick; Cutting has the suspended particulate of dirt under the drag force effect of current, to expand; And filtrate mutual collision friction under former water disturbance of filtering layer bottom makes dirt separate with filtrate, realizes cleaning purpose.The process of whole backwash is all accomplished under the effect of water inlet and water outlet automatically, need not other power-equipment.
Removable filter bed, scrubbing is thorough.In the process of filter tank recoil, when filter back clear water fell to filter plate and exposes, filter material layer began to fall, and filtrate carries out former water through the agitated rinse pipe successively and stirs; After filter material layer fell to minimum point, the backwashing water drain valve cut out, and filter material layer begins to rise, and stirs through former water once more, and the dirt of holding back is thoroughly removed.
It is visualized to work, and ensures even running.The short stream of loss and water route for avoiding filtrate is in closed state below the anti-floating filter plate in filter tank.Be the fluid level condition in observation filter tank, accurately judge the time interval of its course of work and adjustment automatic control, the liquid level indicator tube is set.Liquid level in this indicator tube and the filter tank keeps being communicated with and vertical installation, and the overall process that the filter tank is moved all is in visual state, for timely process parameters provides important evidence, ensures its balance movement.
