Sponge packing

Sponge filler is a filler material used in water treatment or other industrial processes. The following is a detailed description of the sponge filler:

1. Material: Sponge filler is usually made of polyurethane, porous gel and other polymer materials.

2. Structural characteristics: It has a high porosity and porous permeability structure, which can increase the specific surface area of the filler and provide more habitat space for microorganisms.

3. Function:

1. Increase biomass: The large specific surface area of sponge filler provides sufficient space for the growth of microorganisms, so that a relatively high concentration of biomass can be maintained in the biological contact oxidation tank.

2. Enhance biological activity: its porous structure helps to increase the residence time of bubbles and the surface area of gas-liquid contact, improve the oxygen absorption capacity, and thus enhance the biochemical reaction rate of biofilm.

3. Promote mass transfer: high porosity and good air permeability make it easier for wastewater to enter the inside of the filler for biological contact oxidation reaction, and it is also conducive to the normal shedding of biofilm from the filler with water flow, reducing the occurrence of blockage.

4. Scope of application: Often used in high-concentration organic wastewater, various industrial wastewater, oil refining wastewater, daily chemical wastewater, pharmaceutical wastewater and urban domestic sewage nitrogen and phosphorus removal and other sewage treatment projects.

5. Advantages:

1. Good breathability: The porous structure of the sponge filler makes it have excellent breathability, which helps the transmission of oxygen and nutrients and provides a good environment for the growth of microorganisms.

2. High mechanical strength: The sponge filler treated by the network has high mechanical strength and can maintain a stable form in the water treatment process.

3. Good hydrophilicity: The surface of the sponge filler is usually hydrophilic, which is conducive to the attachment and growth of microorganisms.

4. Economical: Compared with other fillers, sponge fillers have a higher cost performance.
