Sludge enhancer, also known as a new type of sludge conditioner, is an effective solution to the problem of unformed municipal sludge pressing. The following is a detailed analysis of the sludge synergist and its solution to the problem of unformed sludge pressing:

1. Mechanism of action of sludge synergists

Sludge enhancer is a chemical agent specially used to reduce sludge viscosity and improve its moisture properties. It usually contains some substances that can destroy hydrogen bonds between sludge molecules, such as polycations, polyanions and so on. These substances can absorb and neutralize the negative charge in the sludge, thereby reducing the viscosity of the sludge. At the same time, they can also make it easier for the water molecules in the sludge to diffuse outwards, improving the water properties of the sludge.

2. Advantages of sludge synergists

Improve sludge compaction performance: By adding an appropriate amount of sludge synergist, the sludge compaction performance of municipal sludge can be significantly improved. After the viscosity of the sludge is reduced, it is easier to be pressed into blocks, and the shaped blocks are harder and not easy to break.

Reduce sludge volume: Because the moisture properties of the sludge have been improved, the volume of the treated sludge will also be reduced. This helps to reduce environmental stress during subsequent treatment and reduce treatment costs.

Improve dehydration efficiency: the sludge synergist can destroy the bacterial structure in the sludge, reduce the solid surface load and specific surface area of the sludge, so as to improve the dehydration efficiency.

Three, the practice of sludge synergist to solve the problem of sludge pressing mud molding

Select the right sludge enhancer: For different types of sludge, different types of sludge enhancer need to be selected. Through laboratory test and field pilot test, the most suitable dosage and dosage of sewage sludge can be determined.

Full mixing: the mixing time of sludge synergist and sludge should be long enough, and the dosing method should be reasonable to ensure uniform mixing. Uneven mixing will affect the dewatering effect of sludge.

Adjust the operating parameters: While using the sludge enhancer, it is also necessary to adjust the operating parameters of the plate and frame filter press according to the nature of the sludge and treatment requirements, such as feed concentration, feed speed, compression force, etc.

Four, precautions

Avoid excessive addition: Although the sludge enhancer can improve the sludge press performance, excessive addition will increase the treatment cost and may lead to problems such as clogging of the filter cloth.

Regular detection of sludge properties: Because the nature of sludge will change with the change of time and treatment conditions, it is necessary to regularly detect the acid and alkali of sludge, organic matter content and other indicators, in order to timely adjust the model and dosage of sludge enhancer.

Maintenance equipment: Regular maintenance and maintenance of plate and frame filter press to ensure the normal operation and stable production of equipment.

In summary, sludge enhancer is an effective solution to the unformed problem of municipal sludge pressing. By selecting appropriate sludge enhancer, mixing fully, adjusting operation parameters and paying attention to related matters, the sludge pressing performance and dewatering efficiency of sludge can be significantly improved, and the treatment cost and environmental pressure can be reduced.
