Combined packing
1, Product introduction
Combined fillers are developed on the basis of soft fillers and semi-soft fillers, which have the advantages of both。The structure is to change the plastic disc pressure buckle into a double ring large plastic ring, and press the aldehyde fiber or polyester filament on the ring ring to make the fiber bundle evenly distributed;The inner ring is a snowflake plastic branch, which can not only hang film, but also effectively cut bubbles, and improve the transfer rate and utilization rate of oxygen。The water gas biofilm can be fully exchanged and the organic matter in the water can be treated efficiently。
2Scope of application
The combined packing is mainly used in sewage and waste water treatment projects, and is equipped with contact oxidation tower, oxidation tank and other equipment. It is a biological carrier of biological contact oxidation method and anaerobic fermentation method to treat wastewater。
3、Performance characteristics
Combined packing has high heat dissipation performance, low resistance, good water and gas distribution performance, easy to long film, and cutting bubbles

4, parameter specifications
Unit diameter Φ150mm, spacing 80mm, 100mm two specifications;The central rope has two kinds of plastic rope and fiber rope。
5Ordering Instructions
Please specify the length, cubic number, spacing, etc. of the required combined packing。
Inclined plate packing
1, Product introduction
Inclined plate packing is mainly made of copolymerization and polypropylene mixture。On the basis of shallow layer theory, a precipitating section with a reasonable precipitation distance is set in the upper part of the inclined plate, and the geometry of the inclined plate is controlled in the lower part, so that a stable contact flocculating section is formed in the lower part of the inclined plate, and the purpose of alum and water separation is achieved through contact action and shallow pool sedimentation mechanism。All kinds of spacing inclined plate packing are supported by plastic ribs of different heights, ribs and inclined plate hot melt welding, each two layers of inclined plate between the need for multiple ribs support, the assembly process is complex, and the traditional inclined plate internal flow channel is rectangular, often suitable for upward flow sedimentation tank。
2Scope of application
Suitable for inlet sand removal, general industrial and domestic feed water precipitation, sewage precipitation, oil separation and tail tension concentration and other treatment。
3, performance characteristics
Wet circumference is large, hydraulic radius is small;The laminar flow state is good, and the particle settlement is not disturbed by floc flow.When the inclined pipe length is 1 meter, the effective load is designed according to 3-5 tons/meter 2·。V0 is controlled at 2.5-3.Within 0 mm/s, the effluent water quality is the best;Adopt honeycomb inclined pipe at the water intake, pipe length 2.0～3.At 0 m, it can be safely operated in the high turbidity of 50-100 kg/m 3 sand content;The processing capacity of the inclined tube sedimentation tank is 3-5 times that of the flat flow sedimentation tank and 2-3 times that of the accelerated clarifier and pulse clarifier。

Stereoelastic packing
Three dimensional elastic fillers were selected for several varieties of polyolefin and polyamide with corrosion resistance, temperature resistance and aging resistance，It is mixed with auxiliaries such as hydrophilic, adsorption and thermal oxygen resistance，Special drawing is used，Silk wool process，Insert the strips into the corrosion-resistant, high-strength center rope，Due to the selection of materials and technology of excellent formula，Moderate rigidity and flexibility，The filament strips are arranged in a stereoscopic uniform radiation state，A monomer of suspended stereoelastic filler was prepared，The packing can spread evenly in all directions in the effective area，Make gas, water and biofilm fully interinfiltration contact exchange，The biofilm is not only uniformly implanted on each filament，Maintain good activity and void variability，And it can obtain more and more specific surface area during operation，And have a good metabolism，This feature and phenomenon is incomparable to other fillers in China。
2Scope of application
Three-dimensional elastic fillers are widely used as biological fillers in biological contact oxidation ponds and hydrolytic acidification ponds。
3, performance characteristics
Compared with rigid honeycomb packing, three-dimensional elastic packing has greater porosity variability and no plugging.Compared with the soft fillers, the material has a long life and does not stick to the agglomeration.Compared with semi-soft fillers, it has large surface area, fast film hanging and low cost。Therefore, the filler can be confirmed as the fourth generation of high efficiency and energy saving novel filler after various hard fillers, soft fillers and semi-soft fillers。
4. Parameter specifications
Diameter 150mm, 180mm, 200mm
5Ordering Instructions
Please specify the length and cubic number of elastic fillers required for ordering。
