Description
Technical field
The utility model relates to industrial cycle water treatment, Industrial Wastewater Treatment, natural former water and advanced treatment process thereof, and is special in the drawer type multi-level fine filter in the water treatment process for purifying under the lower condition of earth surface water source raw water turbidity.
Background technology
In the engineering practice of water treatment, traditional filter type adopts the single or multiple lift filtrate vertically to flow to the water outlet form, can't realize anti-completely granularity filtration (promptly descending) along water inlet direction particle diameter of filter medium, layer phenomenon very easily appears mixing, skewness, both reduced effective holding filth capacity of filtering layer, the difficulty when having increased backwash again makes that the work period of filter shortens, the system water consumption increases, water quality deterioration.Therefore need new filtered version to overcome these problems.
Summary of the invention
The purpose of this utility model is in order to overcome the defective of prior art, and a kind of low cost, less energy consumption, drawer type cascade stage fine filtering device that effluent quality is good are provided.
A kind of water treatment drawer type of the utility model filter is achieved in that by the drawer type setting establishes independently cell filtering ponds at least, filtering ponds all adopt top-down water (flow) direction, top is provided with water inlet pipe and water intaking valve, the bottom is provided with outlet pipe, in be provided with varigrained filter material layer and supporting layer, establish independently backwash water inlet pipe at the bottom of the pond, cell is provided with rhone in the filter tank, external backwash drainpipe, and insert a main sewer.
And, one or more cell filtering ponds tandem compounds are set, water inlet pipe inserts respectively and surmounts pipe and surmount valve.
And described a kind of water treatment drawer type filter is a plurality of cell filtering ponds, and the bottom floor units lattice can be provided with aerator.
This filter is compared with traditional filter form that vertically flows through, effectively utilized the filtering layer volume of holding filth capacity maximum as far as possible, improved the dirty efficient of cutting of whole filtering layer, and reduced the height of whole filter, help arranging in pairs or groups, be prepared into integrated water treatment equipment with other treatment process.The first, the second lattice adopt the filtering layer height little, work the dirty effect that cuts; The filtering layer height of back is big, plays the in-depth filtration effect, guarantees filtering accuracy.
Simultaneously, this filter solves the blockage problem that the conventional quartz sand filtering material occurs between continuous operating period, for subsequent technique lightens the load, thereby in this filter tank, can reach the effect of high-rate fitration with littler thickness of filter bed and higher filtering velocity condition, satisfy the leading indicator requirement of strict national drinking water effluent quality, obtain desirable technology and economic benefit.The backwash system of this multi-level fine filter also has its advantage, can wash separately and does not interfere with each other between level and the level, and the required water consumption of every grade of filtrate flushing is all fewer like this, has saved power consumption water in a large number and has consumed.And the impurity holding filth capacity distribution situation that this water intake mode brought also more helps filtrate backwash from bottom to top.In addition, when raw water quality is relatively good, can reduce progression, energy savings easily.Give at natural former water and industry, in the sewage water filtration treatment process, domesticly do not see this kind form.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, with reference to Fig. 1,2.
As shown in Figure 1, a kind of water treatment drawer type filter, adopt drawer type plural serial stage homogeneous filter bed structure filtered version, be arranged to independently cell filtering ponds (7) by drawer type, separate between the cell, each cell can be finished filtration, backwash process alone, every lattice filtering layer keeps homogeneous texture, and filtering layers at different levels (6) particle diameter of filter medium is along the descending overall anti-granularity structure of filtering layer of water (flow) direction, filtrate adopts different size grading, make the amount of damming of every lattice filtering layer be tending towards maximum, guarantee filtering accuracy simultaneously.
Drawer type plural serial stage fine filtering device, at least establish independently cell filtering ponds (7) by the drawer type setting, water inlet pipe (2) and water intaking valve (1) are arranged on the filtering ponds (7), under outlet pipe (12) is arranged, in be provided with varigrained filter material layer (6) and supporting layer (9), independently backwash water inlet pipe (10) is established at the end, pond (7), is provided with rhone (5) in pond (7), external backwash drainpipe (4), and external main sewer (13).Filter material layer (6) filtrate can be porous make pottery material, quartz and anthracite.
A kind of water treatment drawer type of the utility model embodiment filter, this device is above cell filtering ponds (7) according to actual needs, water inlet pipe (2) inserts respectively and surmounts pipe (8) and surmount valve (3), filter process: former water enters filtering ponds (7) after water intaking valve (1) enters water inlet pipe (2), flow through filter material layer (6), supporting layer (9) filters, flow into and filter the hydrospace, back, flow out through outlet pipe (12); Water can enter next stage after the filter of flowing out, and also can directly discharge through surmounting pipe (8).
Backwash process: water purification is after main (11), backwash water inlet arm (10) are intake in backwash, flow into filtering ponds (7), under pressure, supporting layer of flowing through (9) and filter material layer (6) compile after backwash outlet pipe (4) is discharged filtering ponds (7) at distribution channel (5).
When the multiple-unit lattice are connected as shown in Figure 2, former water is in elevator pump is promoted to this drawer type multi-level fine filter, and this device adopts porous haydite as filtrate, filters the back water outlet and enters the next unit lattice, begin partial filtration, filter back water enters the third level and filters.Utilize the seal-off pressure formula to filter, filtering velocity is 30m/h, front several lattice filtering velocity height, and several lattice filtering velocitys in back are low.The concrete grating of these 3 grades of inner filtering layers is: first order particle diameter is 1.25-1.6mm, and laying depth is 400mm; Second level particle diameter is 0.9-1.25mm, and laying depth is 250mm; Third level particle diameter is 0.8-1.25mm, and laying depth is 200mm.The backwash water inlet flows into from the water distribution eyelet of each cell bottom, and reflexive wash-water gutter flows out behind the whole from bottom to top flushing filtering layer.Adopt water (flow) direction from bottom to top during flushing, visual section dirty degree of each cell filtering ponds is provided with different backwash rates.Backwash can be adopted single lattice flushing, also can wash together by two lattice, also can wash simultaneously by three lattice, and backwash rate is 12L/ (s.m
2), washing length is 5 minutes.When a certain lattice wherein overhaul, perhaps during backwash, can open and surmount valve accordingly, these lattice are surmounted, directly enter the next unit lattice.Can guarantee that so every grade of filter material layer can both obtain abundant backwash, also save energy consumption simultaneously.Backwash is determined by pressure shown in every lattice Pressure gauge.Supporting layer adopts mineral granule, floor height 200mm.
For different quality, this device can be arranged to different processing functions with each cell, thereby carries out water treatment targetedly.When water quality is better, can only adopt a cell to filter; When water quality is relatively poor, adopt the multiple-unit lattice to filter, different units lattice filter material layer adopts anti-granularity to filter; When containing impurity such as iron, manganese when water body the inside, last lattice are added aerator, make filter material layer with natural manganese sand simultaneously, can reach the effect of advanced treating.
