Sludge deep dewatering conditioner has significant application effect in municipal sludge treatment, the following is a detailed analysis of its application in municipal sludge:
Background of Municipal Sludge treatment
Municipal sludge is the solid waste produced in the process of purifying sewage from municipal sewage treatment plants, and its moisture content is usually high, and the transportation and treatment costs are large. In order to achieve the reduction, stabilization and harmfulness of sludge, deep dehydration treatment has become a key step.
Second, the role of sludge deep dehydration conditioner
Sludge deep dewatering conditioner changes the charge properties and hydrophilicity of sludge particles by chemical action, making it easier to separate from water. At the same time, it can also destroy the microstructure of the sludge particles, reduce the specific surface area of the sludge, thereby reducing the contact area between the sludge and water, and improve the dehydration efficiency.
Advantages of municipal sludge
Improve dehydration efficiency: sludge deep dehydration conditioner can significantly reduce the moisture content of the sludge, usually reducing the moisture content from about 80% to less than 60%, or even lower. This greatly reduces sludge volume and reduces transportation and disposal costs.
Improve sludge properties: After the use of conditioning agents, the particle structure of the sludge is more compact and easy to subsequent treatment and disposal. At the same time, it can also control the pH of the sludge, reducing the potential harm to the environment.
Environmental protection: Compared with traditional conditioners such as lime, the new sludge conditioner has lower environmental risks and better environmental performance. It can reduce environmental pollution and meet the requirements of sustainable development.
Economy: Although the sludge deep dehydration conditioner requires a certain investment cost, the overall economic benefits are significant considering the improvement of dehydration efficiency, the reduction of sludge volume and the reduction of subsequent treatment costs.
IV. Application Cases
A municipal sewage treatment plant uses a new type of sludge conditioner to replace the traditional lime for sludge deep dewatering treatment. After a month of trial operation, the following results have been achieved:
The dehydration effect was significantly improved, and the water content of mud cake was reduced by about 5%.
The production of lime mud is reduced, the sludge increment is reduced, and the pressure on the environment is reduced.
Reduced the dehydration cycle by about 10%, helping to reduce operating costs.
Five, precautions
When using the sludge deep dehydration conditioner, it is necessary to select the agent according to the specific nature of the sludge to ensure the best treatment effect.
The dosage of the conditioner should be determined by small and pilot tests to avoid poor dehydration effect or cost increase caused by too much or too little.
In the process of use, we should pay close attention to the dewatering effect and subsequent treatment of the sludge, and adjust the dosage and treatment process of the agent in time.
In summary, sludge deep dewatering conditioner has significant advantages and application prospects in municipal sludge treatment. With the continuous improvement of environmental protection requirements and the continuous progress of technology, it will become an important choice in the field of municipal sludge treatment.
