To solve the problem of too high moisture content of sludge cake, we can start from the following aspects:<

Optimized sludge pretreatment:

Select the appropriate sludge conditioner, such as inorganic salts (lime, iron salt, etc.) or high polymer (polyacrylamide, etc.) to improve the dewatering performance of the sludge.

Control the dosage of conditioner to avoid excessive or insufficient dehydration effect.

Adjust filter press operating parameters:

Adjust the belt speed of the belt filter press, so that it matches the nature of the sludge and the dehydration requirements, to avoid the poor dehydration effect caused by too fast or too slow.

Adjust the tension and pressure of the filter press to ensure that there is enough pressing force between the filter cloth and the sludge to improve the efficiency of dehydration.

Replace or maintain filter cloth:

Check the wear of the filter cloth regularly, and replace the seriously worn filter cloth in time.

Clean the filter cloth, remove the sludge particles and impurities blocked on the filter cloth, and maintain the water permeability of the filter cloth.

Improve sludge quality:

The pretreatment process (such as anaerobic digestion, aerobic digestion, etc.) can reduce the organic content in the sludge and improve the dewatering performance of the sludge.

For sludge containing a lot of grease or heavy metals, take targeted treatment measures, such as adding demulsifier, precipitator, etc.

Introducing new dehydration technologies:

Consider using more efficient dewatering equipment such as centrifugal dewatering machine and plate and frame filter press to improve the dewatering efficiency.

Explore the use of new sludge dewatering technology, such as microwave dewatering, ultrasonic dewatering, etc.

Strengthen sludge management:

Reasonable arrangement of sludge storage and transportation to avoid long-term accumulation caused by changes in sludge properties.

Strengthen the monitoring and data analysis of the sludge treatment process, and adjust the operating parameters and treatment technology in time.

Consider sludge resource utilization:

Explore the way of sludge resource utilization, such as converting sludge into fertilizer, fuel, etc., to reduce sludge production and reduce treatment costs.

In summary, to solve the problem of too high moisture content of sludge cake, we need to start from many aspects, including optimizing sludge pretreatment, adjusting the operating parameters of filter press, improving sludge sludge quality, introducing new dehydration technology, strengthening sludge management and considering sludge resource utilization. Through comprehensive policies, the moisture content of sludge cake can be effectively reduced and the efficiency of sludge treatment can be improved.
