Combined fillers are developed on the basis of soft fillers and semi-soft fillers, which have the advantages of both.

The following are detailed instructions for the combined fillers:

1. Material: Generally made of plastic, fiber and other materials.

2. Structure: composed of fiber bundle, plastic ring, etc.

3. Features:

1. Large specific surface area: it can provide a large biological attachment area.

2. Good water flow conditions: conducive to the renewal of biofilm.

3. High oxygen utilization rate: promote the metabolic activities of microorganisms.

4. Scope of application: Often used in biological contact oxidation ponds in sewage treatment.

5. Advantages:

1. Fast film hanging: can shorten the culture time of biofilm.

2. Corrosion resistance: can adapt to different working environments.

3. Customizable: Different specifications can be customized according to actual needs.

6. Installation points:

1. Smooth installation to avoid distortion.

2. Reasonable spacing to ensure even water flow.

7. Use precautions:

1. Check regularly: Whether there is damage or blockage.

2. Prevent excessive load: avoid exceeding its processing capacity.

The combined filler can effectively improve the treatment effect in sewage treatment.
