Sludge enhancer is a chemical agent that can change the surface structure of the sludge, reduce the surface load of the sludge solid and the specific surface area of the sludge surface, and thus destroy the bacterial structure of the sludge. It plays a vital role in the sludge treatment process, especially in the deep dehydration stage, and can significantly reduce operating costs. The following is a detailed analysis of sludge synergists to achieve deep dehydration and reduce operating costs:
One. Mechanism of action of sludge synergists
The main components of sludge enhancer include inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent, etc. These ingredients work together to change the physical and chemical properties of the sludge, making it more susceptible to dehydration. Specifically, the sludge synergist can destroy the colloidal structure and bacterial structure in the sludge, so that the sludge particles are dispersed, and the free water is more easily filtered out.
Two, the advantages of sludge synergists to achieve deep dehydration
Reduce sludge moisture content: sludge enhancer can effectively reduce the moisture content of sludge, usually can reduce the moisture content of sludge from more than 90% to 40%-55%. This significant dewatering effect helps to reduce the volume and weight of the sludge and reduce the transport and disposal costs of the sludge.
Improve dehydration efficiency: After the use of sludge enhancer, the mud pressing efficiency of the dehydration equipment can be significantly increased by 100% to 500%, and the mud pressing cycle is greatly shortened. This can not only increase the speed of sludge treatment, but also reduce the operating time and energy consumption of the equipment.
Improve sludge flow: Sludge synergists can improve the flow of sludge, making it easier to flow and press in the dehydration equipment. This helps to reduce the wear and blockage of the sludge on the dewatering equipment and extend the service life of the equipment.
Three, sludge synergist to reduce the way of operating costs
Reduce the amount of agents: the addition of less sludge synergist can achieve significant dehydration effect. This will not only reduce the amount of medicine used, but also reduce the cost of purchasing and storing the medicine.
Reduce equipment maintenance costs: Because the sludge synergist can improve the fluidity of the sludge and reduce the wear and blockage of the sludge on the dewatering equipment, the maintenance cost of the equipment can be reduced. At the same time, the sludge booster non-stick filter cloth, reduce the frequency of dewatering equipment to replace the filter cloth, but also save the operating cost.
Reduce the cost of subsequent treatment: the moisture content of the dehydrated sludge is reduced, and the volume is reduced, which is convenient for subsequent transportation, storage and disposal. This can not only reduce the difficulty and cost of follow-up treatment, but also improve the utilization value of sludge, such as for incineration, brick making, composting and so on.
Four. Practical Application Cases
Many wastewater treatment plants and industrial wastewater treatment facilities have successfully applied sludge enhancers. For example, after the introduction of sludge enhishers in a sewage treatment plant, the dehydration efficiency of the sludge was increased by more than 30%, and the water content of the dehydrated mud cake was reduced from the original 80% to less than 60%. This not only improves the sludge treatment efficiency, but also reduces the treatment cost, and brings significant economic benefits to the operation of the sewage treatment plant.
In summary, sludge synergists have significant advantages in achieving deep dewatering of sludge and reducing operating costs. Reasonable selection and use of sludge enhancers can significantly improve sludge treatment efficiency and quality, and reduce treatment costs and environmental risks.
