What are the advantages of the sludge thickener, and what are the thickening methods?

The sludge thickener can reduce capital investment and land occupation, reduce the emission of odor and phosphorus, and reduce the burden of subsequent processing; the commonly used thickening methods include air flotation thickening, gravity thickening, centrifugal thickening, belt gravity thickening, etc. , The following is a specific introduction to "the advantages of the sludge thickener and the method of thickening".

1. Advantages of sludge thickener

1. Reduce infrastructure investment and land occupation

2. Reduce odor and phosphorus emissions

3. Reduce the burden of subsequent processing

4. Increase the capacity of sludge dewatering or deep dewatering equipment

Second, the thickening method of the sludge thickener

1. Air flotation concentration method

Air flotation concentration is to release the gas dissolved in water in the form of microbubbles, and it can quickly and evenly attach to the sludge solid particles, making the density of the solid particles smaller than water and floating, so as to achieve the separation of solid particles and water. Methods.

2. Gravity concentration method

Gravity concentration uses the relative density difference between the solid particles in the sludge and water to achieve sludge concentration. If the gravity concentration method is adopted, the water content can be reduced from 99, 2%-99, 6% to 97%-98%. For sewage treatment plants with primary and secondary sedimentation tanks, these two types of sewage can be After the mud is mixed, it is concentrated by gravity.

3. Centrifugal concentration method

The principle of the centrifugal concentration method is to use the different centrifugal force of the solid and liquid specific gravity in the sludge to concentrate. Suitable for biological and chemical sludge in large and medium-sized sewage treatment plants.

4. Belt gravity concentration method

The belt gravity concentration method is a mechanical concentration method using a belt gravity thickener. During operation, it will be affected by the macromolecules in the sludge, and the humidity during operation is high, so careful operation is required.
