For the problem of high moisture content of mud cake and sticky filter cloth, the following are some specific solutions:
One. Optimization of sludge treatment technology
Increase press pressure:
In the process of sludge dewatering, increasing the pressing pressure can significantly reduce the moisture content of mud cake.
Equipment such as high-pressure sludge filter press can be considered for dewatering operations at higher pressures.
Optimization of flocculation conditions:
The flocculation effect directly affects the dewatering performance of sludge.
Conditions such as selection and dosage of flocculant, stirring intensity and settling time should be re-evaluated.
Selecting the appropriate flocculant and optimizing the dosage, while ensuring the moderate stirring intensity, can significantly improve the flocculation effect of sludge.
Use of sludge conditioner:
The sludge conditioner can change the surface structure of the sludge, reduce the solid surface load and specific surface area of the sludge, destroy the bacterial structure, and improve the dewatering performance of the sludge.
Selecting suitable sludge conditioner for pretreatment can effectively reduce the moisture content of mud cake.
Two, improve the dehydration equipment
Select the right dehydration equipment:
Select the appropriate dewatering equipment according to the nature of sludge and treatment needs.
For sludge with higher moisture content, efficient dewatering equipment such as plate and frame filter press, belt filter press or centrifuge can be considered.
Regular maintenance and upgrade of equipment:
Maintain and upgrade the dewatering equipment regularly to ensure its efficient operation.
Maintenance includes cleaning the filter, checking the sealing performance, etc. Upgrades may involve the replacement of more efficient dewatering elements or the adoption of more advanced control technology.
Three, improve the filter cloth performance
Select the right filter cloth:
The quality of filter cloth directly affects the dewatering effect and the quality of mud cake.
Filter cloth with good filtration performance and anti-viscosity should be selected, and ensure that the filter cloth is fixed in the right position, tight and smooth.
Regular cleaning of filter cloth:
Filter cloth is easy to block or residual sludge after a long time of use, affecting the dehydration effect.
The filter cloth should be cleaned regularly to keep it clean and unblocked.
Avoid filter cloth damage:
Broken filter cloth will cause the mud cake to break and water can not be smoothly discharged.
The integrity of the filter cloth should be checked regularly and the damaged filter cloth should be replaced in time.
Iv. Comprehensive consideration of environmental factors
Adjust temperature and pH:
Environmental factors such as temperature and pH value may affect the dewatering performance of sludge.
These factors should be fully considered in actual operation, and corresponding measures should be taken to adjust and optimize.
Focus on environmental protection and sustainability:
In the selection of agents and equipment should consider its impact on the environment and subsequent sludge disposal methods.
Avoid the waste of other energy or secondary pollution caused by the reduction of sludge.
