Combined filler
Composite fillers are developed on the basis of soft fillers and semi-soft fillers, both. Its structure is to press and buckle the plastic disc into a double-circle large plastic ring, and press the aldehyde fiber or polyester fiber on the ring to distribute the fiber bundle evenly. The inner ring is made of snowflake-shaped plastic support, which can not only hang the film, but also cut the air bubbles effectively, which improves the oxygen transmission speed and utilization rate. The water gas biofilm can be fully exchanged, and the organic matter in the water can be effectively treated.
It is a biological carrier for wastewater treatment by biological contact oxidation and anaerobic fermentation. It is widely used in sewage and wastewater treatment projects, and matched with contact oxidation towers, such as oxidation pond and oxidation pond equipment.
