Hexagonal honeycomb inclined tube filler is mainly used for all kinds of precipitation and Desanding effect. In the last ten years to the drainage works in the most widely used and has become a water treatment plant. It is suitable for a wide range of high treatment efficiency, small footprint advantages. Suitable for intake Desanding, general industrial and domestic water sedimentation, sewage sedimentation, grease and Owari enrichment and other processing, apply to new construction, but also for the transformation of the existing old pool, it has achieved good economic results. High load biofilter straight pipe is mainly used for biofilter tower biofilter, submerged biofilter (also known as contact oxidation pond), and microbial bio-wheel vehicle, industrial organic wastewater and urban sewage biological treatment . 3. When the oblique images welded pipe length is 1 meter, the payload of 3-5 t / m 2? Design. V0 controlled within 2.5-3.0 mm / sec, the best water quality. 4. The use of environmentally friendly green hexagonal honeycomb Ye at the water intake at the inclined tube filler, 2.0 to 3.0 m long pipe, it can deal with the safe operation of 50-100 kg / m 3 silt content of high turbidity. 5. Using Sedimentation, its capacity is 3-5 times advection sedimentation tank, accelerating pool and pulse 2-3 times to clarify the clarifier. An inclined pipe has been installed, the process is more efficient than activated sludge, general hydraulic loading of 100-200 m 3 / m 2? Days, organic load of 2000-5000 g / m 3, thus reducing the footprint. 2, below the activated sludge aeration intensity, and without sludge return, it can reduce power consumption and simplify management. 4, the resulting sludge settling, and is conducive to remove the rear section of suspended solids. 5, adaptable, able to adapt to a wide range of different water quality, patient and strong for water quality, quantity mutations impact load to maintain the stability of the treatment effect.
