200mm Polyester + PP Composite Packing For Waste Water Treatment

Composite packing is another kind of packing improved on the basis of soft packing, which is composed of fiber bundle, plastic ring piece, casing pipe and intermediate rope. Under the support of intermediate plastic ring piece, fiber bundle avoids the phenomenon of middle agglomeration of fiber bundle, at the same time, it can play a good role in water distribution and air distribution, has good contact and mass transfer conditions, and has high utilization rate of oxygen. It is suitable for various sewage and wastewater treatment projects In contact with oxidation wall, oxidation tank, oxidation tank and other equipment, the advantages of soft and semi soft packing are overcome, which are ideal products in the biochemical treatment of sewage. Parameters and specifications of combined packing: diameter: φ 150 mm, φ 180 mm, φ 200 mm, spacing: 80 mm, 100 mm.

1. It has a plastic ring as the skeleton, loaded with vinylon wire, which is fastened on the plastic ring. In the sewage, the tow is evenly distributed, easy to form and change the membrane, and has good adaptability to the sewage thick liquid.

2. The structure is to change the plastic disc buckle into a double circle big plastic ring, and press the aldehyde fiber or polyester fiber on the ring to make the fiber bundle evenly distributed.

3. The inner ring is a snowflake shaped plastic branch, which can not only hang film, but also effectively cut bubbles, improve the transfer rate and utilization rate of oxygen, make the water gas biofilm have full exchange, and make the organic matter in the water have efficient treatment. The combination packing is the best choice under the condition of strong aeration turbulence.

4. Application of combined packing: it is used in sewage and wastewater treatment engineering, matched with equipment such as contact oxidation tower and oxidation tank of oxidation pool, and is a kind of biological carrier for wastewater treatment by biological contact oxidation and anaerobic fermentation.

5. Performance characteristics of combined packing: it has high heat dissipation performance, small resistance, good water and air distribution performance, easy to generate film, change film, good applicability to sewage concentration, and has the effect of cutting bubbles.

Application

The composite packing is used in sewage and wastewater treatment engineering, matched with contact oxidation tower, oxidation tank and other equipment. It is a kind of biological carrier for the treatment of wastewater by biological contact oxidation and anaerobic fermentation.

It is widely used in printing and dyeing, silk spinning, food, pharmaceutical, petrochemical, papermaking and other wastewater treatment, so it is welcomed by the majority of users.

Installation

There are square, equilateral triangle and other installation methods. The frame has steel structure and soft rope structure, which are made into upper and lower layers respectively. The distance between the two layers is the effective length of the filler. The two ends of each piece of packing

are provided with ropes for binding. During installation, special knotting method is used to fix the packing on the upper and lower frames.
