In view of the problems that the mud is too thin, the moisture content is high, and the sludge is not formed, the following measures can be taken to solve them:
First, adjust the sludge treatment process
Optimize filter press equipment parameters
According to the characteristics of the sludge and water content, adjust the parameters of the filter press equipment, such as pressure, filtration time, etc., to improve the filter press effect.
Adding sludge conditioner
By adding an appropriate amount of sludge conditioner (such as polyacrylamide PAM, etc.), the dewatering performance of the sludge can be effectively improved. The conditioning agent can flocculate the sludge particles through chemical action, improve the settling and filterability of the sludge, and thus reduce the water content.
Select the appropriate conditioner according to the sludge characteristics, and adjust the dosage to achieve the best effect.
Introduction of hot drying technology
For refractory sludge, hot drying technology can be considered to reduce the moisture content of sludge through high temperature heating. However, this method has high energy consumption and cost, and economic benefits need to be considered comprehensively.
2. Strengthen sludge management
Regular maintenance of filter press equipment
Regularly clean and maintain the filter cloth and filter plate of the filter press equipment to prevent blockage and damage and ensure the normal operation of the equipment.
Monitoring changes in sludge properties
Sample and analyze the sludge regularly to understand the changes in the properties of the sludge, such as acid and alkali, organic content, etc., in order to adjust the treatment process in time.
Reasonable control of feed pressure and feed quantity
Ensure that the feed pressure and feed amount of the filter press are within a reasonable range to avoid insufficient feed pressure or excessive feed amount resulting in unformed sludge.
3. Use other auxiliary methods
Biological treatment technology
Use biological treatment technology to degrade organic matter in sludge, reduce sludge volume and reduce water content. This approach is environmentally friendly and sustainable, but it takes time and conditions.
Natural dehydration or drying
For sludge with high moisture content, natural dehydration or drying treatment can be used to further reduce the moisture content. Natural dehydration is to dehydrate the sludge in a ventilated and sunny place; Drying treatment is the use of hot air or solar energy and other equipment to evaporate the water in the sludge.
Iv. Comprehensive Measures
In actual operation, it is often necessary to take a variety of measures to deal with sludge problems comprehensively. For example, while adjusting process parameters, sludge management is strengthened and other auxiliary methods are introduced. Through comprehensive policies, the problems of unformed sludge and high moisture content can be solved more effectively.
In summary, to solve the problem that the mud is too thin after mud pressing, the moisture content is high, and the sludge pressing is not formed, it is necessary to start from many aspects. By optimizing process parameters, strengthening sludge management, adopting other auxiliary methods and comprehensive policies, the sludge treatment effect can be significantly improved and the water content can be reduced.
