Biodegradability and water distribution properties of elastic filler
- Jan 31, 2019 -

Compared with the hard type honeycomb filler, the elastic filler has large pore variability and no clogging. Compared with the soft type filler, the material has a long service life and a non-adhesive joint group, and has a large surface area compared with the semi-soft filler. The film is fast and the cost is low. 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. At present, it is widely used in the hydrolysis and acidification section of the refractory organic matter treatment process to improve the biodegradability of the sewage.

The elastic filler is used for sewage and wastewater treatment projects, and is matched with equipment such as contact oxidation tower and oxidation tank oxidation tank. It is a biological carrier for treating wastewater by biological contact oxidation method and anaerobic fermentation method. It is widely used as biological filler in biological contact oxidation tank and hydrolysis acidification tank.

The elastic filler is made of high molecular polymer and added with additives such as antioxidant, hydrophilic agent, stabilizer, adsorbent, etc., and the special wire drawing has a fine burr structure, and the elastic wire is bonded at high temperature and firmly fixed on the plastic particles. Forming a sheet-type elastic three-dimensional filler. The filler is corrosion-resistant, has a large specific surface area, and is easy to hang the film. It is easy to remove the film after periodicity and is quick to update. Has a good cloth and water performance.
