Sewage treatment is an important link in the modern social environmental governance, and as an indispensable part of sewage treatment equipment, filler plays a vital role in improving the efficiency of sewage treatment and water quality. As an auxiliary substance commonly used in sewage treatment equipment, its price is cheap and the use effect is good, mainly used for contact oxidation process, microorganisms will be attached and accumulated on the surface of the filler to increase the contact surface with sewage, degradation of sewage treatment, and then improve the biodegradability of wastewater. Today, let's take a look at the commonly used wastewater treatment fillers.
1. Soft fiber filler
Composition: PE center rope + Aldehyde Vinylon silk bouquet
Application: Soft filler has large surface area, high utilization rate, variable void and non-blocking, low cost, good overall use effect, so the cost performance is high, suitable for large sewage treatment equipment.
2. Semi-soft filler
Composition: PE center rope ＋PE ring tablet
Application: Suitable for anaerobic and anaerobic tanks, and also for aeration tanks. Semi-soft fillers have special structure and hydraulic properties, large porosity (greater than 96%), small flow resistance, not easy to tangle, blockage, but difficult to hang film, sludge reduction is not obvious. Generally suitable for small sewage treatment.
3. Composite fiber filler
Composition: PE center rope ＋ PE ring table ＋ Aldehyde Vinylon silk bouquet
Application: Suitable for anaerobic, anaerobic, aeration tank. It is easy to hang and remove film, the sludge reduction effect is obvious, the overall use effect is good, the cost performance is good, and it is suitable for large-scale sewage treatment equipment.
4. Elastic three-dimensional packing
Composition: PE center rope ＋ PP elastic wire
Application：Suitable for anaerobic, anaerobic, small amount for aeration tank. It is easy to hang and remove film, the sludge reduction effect is obvious, the overall use effect is poor, the cost is low, the cost is low, and it is suitable for general small and medium-sized sewage treatment equipment.
5. Suspended filler
Composition: PE shell + aldehyde Vinylon silk bouquet or PP wide flat ribbon
Application: Suitable for anaerobic, anaerobic, also used in aeration tank. It is easy to hang and remove film, the sludge reduction effect is general, the overall use effect is general, the cost is high, and it is suitable for transformation or small sewage treatment equipment and fluidized bed.
6. Inclined suspension porous suspension filler (MBBR)
Composition: PP
Application: It is suitable for raw water treatment of tap water, and the effect is very good. It can also be used in anaerobic tank, aeration tank and biological fluidized bed of sewage treatment unit. High cost performance.
7. Torx ring
Composition: PP
Application: The annulus ring filler has the advantages of large voidage, not easy to be blocked, large flux, small resistance, etc., because the gap of this filler can have a higher liquid retention, which can make the liquid stay in the tower longer, thereby increasing the contact time of gas and liquid, and improving the quality efficiency. It is suitable for small tower-type biofilm processing device with small floor area.
8. Biological rotating disc
Composition: Fiberglass or plastic
Application: The disk body is composed of a series of closely spaced disks mounted on a horizontal axis, one part of which is immersed in the sewage of the oxidation tank, and the other part is exposed to the air. The surface area of biofilm growth in the turntable is large, and it will not occur such as the phenomenon of filter material blockage in the biological filter, even if the blockage is easy to clean, the biological turntable has no possibility of sludge swelling, so the concentration of influent organic matter is allowed to be high. The material cost is high, and it is suitable for membrane biological treatment devices with small daily processing capacity.
9. Modified fiber ball packing
Composition: Polyester fiber
Application: Modified fiber ball is a spherical filter material made of fiber wire. Compared with traditional rigid filter material, it has the advantages of good elastic effect, no floating surface, large gap, long working cycle, and small head loss. The modified fiber ball not only has a better effect of removing suspended matter and oil, but also does not leak out and the filter layer is not congealing. High cost performance, suitable for high efficiency filter, biological fluidized bed.
10. Honeycomb inclined tube packing
Composition: PP or PVC
Application: This kind of filler is no noise, environmental protection, good use effect, wide application range of inclined tube filler, high treatment effect, small footprint, suitable for inlet sand removal, general industrial and domestic water supply precipitation, oil separation and tailings concentration, etc., honeycomb inclined tube filler is suitable for both new projects and for the transformation of existing old pools, high cost performance.
11.Bauer ring, ladder ring, polyhedral sphere, Lacey ring, Hale ring
Composition: Metal, plastic (PP, etc.), ceramic, etc
Application: It has the advantages of large flux, low resistance, high separation efficiency, strong production capacity and large operating flexibility, etc., various materials, high cost performance, suitable for air treatment filtration tower, sewage treatment device, fluidized bed device.
