Compare with traditional technology:
1) effluent quality is good and stable.The filter cloth rotary disc filter is to adopt filter disc outsourcing filter cloth to replace the sand filtering material in traditional filter tank, and the filter cloth aperture is very little, and can hold back particle diameter is the molecule of several microns (μ m), so effluent quality and stable water outlet all are better than the pellet filter tank.
(2) modern design, anti impulsion load.The filter cloth rotary disc filter is the equal of the combination of filter tank and sedimentation basin, has the function of spoil disposal.The mud that particle is big directly is deposited at the bottom of the bucket shape pond, can not stop up filter cloth, and namely unlike general filter chamber: all suspensions (SS) all must be through filtrate.
(3) simple and compact device, auxiliary device is few, and the investment of whole filtration system is low.But continuous filtration when the filter cloth rotary disc filter cleans.And can not continuous filtration during the sand filter backwash, for guaranteeing continuously, tank or adopt Duo Tai filter tank alternation in the middle of need before sand filter, establishing.
(4) lness ratio of plant is low, and total installed capacity power is low.Because filter cloth is thinner, be very easy to rinse well, clean very efficiently, during cleaning, the area of cleaning filter disc only is equivalent to 1% of whole filter disc area.
(5) operation automation, thereby move and safeguard simple, convenient.Filter process can be adjusted blanking time and the process of negative pressure suck purge process and spoil disposal process and be lasted by computer control.Substantially do not need special messenger's maintenance management.
(6) loss of flood peak is little more a lot of than sand filter.The filter cloth rotary disc filter is generally 0.2m, and that the loss of flood peak of sand filter is generally 1.5m is many.The loss of flood peak of sandfiltration pot then is higher than 5m, and energy loss is big, increases operating cost.
(7) floor space is little more a lot of than other filter tanks.Because the design of filter disc vertical centering control blank pipe makes little floor space can guarantee big filter area, thereby has reduced the pond appearance, has reduced quantity of material and earth volume, has significantly reduced construction costs.
(8) the filter cloth rotary disc filter is easy to install than pellet filter tank.After on-the-spot tube connector accessory and the electrical equipment, can come into operation.The pellet filter tank then often needs to carry out filtrate and installs.
(9) design cycle and short construction period.Filter cloth rotary disc filter integral deviceization can whole be loaded and transported, and design and easy construction are also quick; And enlarging easily.
(10) endurance requirement in base is low over the ground, the small investment of equipment ground.
The comparison of several filter type investments, ruuning situation:
The operating cost of turntable filter chamber is very low, the operating cost of handling one ton of water have only 0.004 yuan (li), and traditional handicraft (V-type filter tank, D type filter tank, fibre bundle/ball filter tank) operating cost is 0.2-0.3 unit, is example with 10,000 tons of water, just can save 500,000-700,000 yuan in 1 year.
The above only is the specific embodiment of the present invention, but the invention protection domain be not limited thereto, any variation or replacement of expecting without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
