Sludge enhancer is a chemical agent specially used to solve the problem of high water content of sludge. The following is a detailed analysis of the sludge synergist to solve the problem of high sludge moisture content:
One. Mechanism of action of sludge synergists
Sludge enhancer achieves deep dewatering of sludge mainly by changing the surface structure of sludge, reducing the surface load and specific surface area of sludge solids, and destroying the bacterial structure in sludge. These chemicals can react with colloidal particles in the sludge, neutralize their surface charges, promote the agglomeration and sedimentation of the particles, and thus release the water in the sludge.
Two. Application effect of sludge synergist
Significantly reduce the moisture content: The combination of sludge enhancer and filter press and other equipment can significantly reduce the moisture content of sludge. According to the actual use, the moisture content of the sludge can be reduced from more than 90% to 40% to 60%, or even lower.
Improve dewatering efficiency: sludge synergists can accelerate the dewatering process of sludge, shorten the dewatering time, and improve production efficiency. At the same time, it can also reduce the blockage and wear of the filter press and extend the service life of the equipment.
Improve sludge properties: After sludge enhancer treatment, the physical and chemical properties of the sludge are improved, and it is easier to follow-up treatment and disposal. For example, the particles of sludge become larger and more compact, which facilitates subsequent treatments such as incineration, brick making or composting.
Selection and use of sludge synergists
Select the right sludge enhancer: When selecting the sludge enhancer, it is necessary to consider the nature of the sludge, treatment process and equipment conditions and other factors. Different types of sludge synergists have different characteristics and scope of application, so it is necessary to choose according to the actual situation.
Determine the reasonable amount: the amount of sludge enhancer needs to be determined according to the water content of the sludge, the scale of treatment and equipment conditions. Overuse will not only increase costs, but may also adversely affect subsequent treatment. Therefore, it is necessary to test and debug before use to determine the best dosage.
Pay attention to the conditions of use: the conditions of use of sludge enhancer include temperature, pH value, stirring intensity, etc. These conditions have an important influence on the effect of sludge enhancer. Therefore, these conditions need to be strictly controlled during use to ensure the best treatment results.
Four, sludge synergist precautions
Safety: The sludge synergist is usually a chemical, with a certain toxicity and corrosion. It is necessary to pay attention to safety protection during use to avoid harm to the human body and the environment.
Environmental protection: When selecting sludge enhancer, it is necessary to consider its environmental performance. Priority is given to non-toxic, harmless and degradable sludge synergists to reduce environmental pollution.
Economy: The cost of sludge enhancer is also one of the factors to be considered. Under the premise of ensuring the treatment effect, the selection of low cost and cost-effective sludge enhancer is conducive to reducing the overall treatment cost.
In summary, sludge enhancer is an effective chemical agent to solve the problem of high sludge moisture content. The dewatering efficiency, moisture content and properties of sludge can be improved significantly by selecting suitable sludge synergist, determining reasonable dosage and using conditions. At the same time, it is necessary to pay attention to the requirements of safety protection and environmental protection performance during use.
