Description

Filter bed device under a kind of 360 degree water inlet rotating waters
[technical field]
The utility model relates to filtration art, specifically filter bed device under a kind of 360 degree water inlet rotating waters.
[background technology]
In water technology, sewage is by the particulate filter layer time, some suspended materials wherein and colloidal substance just are trapped within hole or on dielectric surface, and this method by granular media layer separatin non-soluble pollution impurity is called granular media filters, and is called for short and filters.Filtration mechanism is thought at present and is mainly contained: sieving effect, settlement action and adsorption-condensation effect.The range of application that water and sewage water filtration are processed is mainly: 1. remove turbidity in former water and colloid etc.; 2. remove the tiny chemical flco that tiny biological floe that the biological treatment second pond do not removed or coagulative precipitation tank are not removed; 3. improve the clearance of SS, turbidity, BOD, COD, phosphorus, heavy metal, bacterium and virus etc.; 4. be that advanced treating and reuse operation (as charcoal absorption, membrane filtration, ion-exchange etc.) are created good condition of water quality.
The form in filter tank is varied, is the most basic pattern with quartz sand as the conventional rapid filter of filtrate.For giving full play to filter material layer impurity trapped ability, double-deck, multilayer and even-granular filter have been developed, upward flow and bidirectional flow filter tank etc.For the gentle minimizing of the Automated water that improves operation filter tank valve, siphon filter, valveless filtering pool, moving flushing cage filter chamber, other hydraulic automatism have occurred and rinsed filter tank, filtering cloth filtering pool etc.On backwashing manner, there is simple water to rinse and the air-water backwashing mode.Staggered carrying out normally filtered and rinsed to the process of filter progress.In sewage disposal there be filter tank commonly used:
1) conventional rapid filter: this is a kind of filter tank of the most generally using both at home and abroad, stable and reliable operation, and large resistance water distribution system, effluent quality is good; But its shortcoming is: valve is many, and operational administrative is cumbersome, generally is used for large and medium-sized Sewage Plant.Filtrate uses quartz sand usually, and quartz sand has enough mechanical strengths, and price is low, and material is easy to get, and is all very stable in neutrality and subacidity water.Filter and mainly utilize the surface area that in filtering layer, bulk material provides, the suspended solid of process coagulating treatment in trap water.When the loss of flood peak of filtering reaches maximum, or the turbidity of filtrate or other predetermined water quality parameter occur when defective, need carry out the backwash in filter tank.Opposite when during backwash, water (flow) direction is with filtration, utilize the percussion of current and the friction between filtrate to remove the suspended solid that filtering layer is held back.
2) the development pattern filter tank of conventional rapid filter: as double-valve filter pool, shutter filter, double layer filter etc.
3) V-type filter tank: the V-type filter tank is a kind of high speed homogenization filter material filter pool of French moral profit full (Degremont) company exploitation, and the significant advantage that holding filth capacity is large, developing result is good is arranged.Individual layer thickening quartz sand filter media is adopted in this filter tank, and deep layer is cut dirty mode.Backwashing manner is air-water backwashing, and is provided with surface cleaning cloth tank, and developing result is good.Water distribution system adopts strainer head, can be not if establish very thin supporting layer.The V-type filter tank is a kind of Novel filter faster of development at present.The shortcoming in this filter tank is that equipment is slightly complicated, and filtration expense, civil engineering specification requirement are higher.
4) gravity valveless filter: valveless filtering pool is to utilize the pipe-line system of design to control the filtering layer resistance, when reaching limit value, and automatic backwash.This filter tank operation all automatically, and is easy to operate, the negative head phenomenon can not occur in running; Without large size valve, cost is than low with the scale general filter chamber.Its shortcoming is to use small resistance water wiring system, low water head recoil Xian, and backwash is inhomogeneous, and phenomenon easily is short-circuited.Pipe fitting is more complicated, and is strict to what install.
5) pressure filter: pressure filter is generally the rapid filter that GB150-1998 is made, and adopts large resistance water distribution system, and backwash is even.Can directly utilize the overbottom pressure water outlet.The varying head constant speed filter, water quality is filtered not as slowing down.Single pool area is little, can only be used for the little water yield Sewage Plant of utilizing without elevation.
In present domestic and international filtering technique research and development, the research emphasis of filtering technique and pond, filter tank type is to increase the filter tank to contain dirty ability, improves filtering velocity, improves effluent quality, secondly simplifies the operation, and improves the level of automation and continued operation.
Start with from changing media performance, researched and produced ceramic grain filter, porcelain sand filter material, fiber filtering etc.Wherein, ceramic grain filter mechanical strength and chemical stability are better, and filtering velocity is large.Fiber filtering has been broken through the restriction that the material footpath of particulate filter can not further dwindle, and makes the diameter of filtrate reach μ m level, has increased specific area and the adsorption capacity of filtrate.Aspect the development of filter tank pattern, occurred:
1) upward flow filter: the filter bed containing filth amount is large, does not produce negative head and air-resistance phenomenon, but filtering velocity can not be too high.During filtration, after filter, water goes out stream on top, pond, can observe at any time the situation of filtrate.Dirt concentrates in the coarse media of bottom mostly, more difficult rinsing well during backwash.
2) continuous filtration pool (device): continuous filter has showed a kind of new filtration and cleaning way, current being considered to, have one of filter of development most, it moves to the cleaning of filtrate outside the filter tank, make filter continuous reforwarding row, without the process that stops production and rinse, the loss of flood peak is lower and relatively constant.The shortcoming of this kind filter is complex structure, and treating capacity is little.
3) the pressure filter filtration of pumping up, flow process is simple, processes operation for small-scale sewage convenient, uses more.
But also there are many problems in present filter tank design and running, as:
1) negative head and air-resistance phenomenon
When the loss of flood peak that is increased to filtering layer when filtration resistance surpassed the filtering cloth head at this place, the negative head phenomenon will appear.Negative head can cause air to discharge, and increases the filtering layer local resistance.When rinsing, air is taken away the part filtrate with water, causes the local large particle diameter column of filtering layer, filters thereby make the phenomenon that is short-circuited.
Vapour lock be due to local accumulation in filter material layer air, reduce to filter the water yield, form the filter material layer crack, filtering water worsens.
2) contamination
There is the dead angle in filtering layer, builds up colloidal substance mud and mutually bond.
3) run hourglass sand
Backwash rate is excessive or the filtrate grating is improper, and backwash can wash away a large amount of filtrates.Or the flushing water maldistribution, supporting layer can be moved, so that filtrate runs off by water distribution system.
Two kinds of methods of general employing such as the filtration of mud-water separation, water at present:
1) traditional filtering method (take sand filter, filtering tank etc. as representative)
It is characterized by: adopt pond type or barrel shape, the inner filtrate of placing, the vertical layout, former water enters filter bed from top to bottom or from bottom to top, by the suspension in the filtrate trap water etc.;
Advantage is: filtering accuracy is higher, and is less demanding to the concentration limit of water inlet suspension;
Shortcoming is: one direction is filtered, and floor space is large, and during backwash, recoil all must be united with air water in the bottom of whole filtering surface, and the air water requirement of strength is high;
2) another filtering technique is the filtering cloth filtering pool technology at present, it is characterized by: adopt filter cloth, as fiber filter cloth or stainless steel filter cloth, also can be placed under water, and can rotate.But it does not adopt depth filtration, deep bed filtration.
Advantage is: floor space is little, and filtering cloth head is lower;
Shortcoming is: holding filth capacity is little, and filtering accuracy is lower, requires the concentration of water inlet suspension lower, and backwash is frequent.
