Municipal sludge contains not only a large number of microorganisms, mechanical properties and rich nitrogen, potassium and other nutrients, but also excessive heavy metals, pathogenic microorganisms and so on. At present, the moisture content of municipal sludge is mostly about 80%. Sewage treatment plant municipal sludge is the main source of sludge in China, and the sludge content is high, more difficult to dehydrate than industrial sludge. The big problem it faces is that the sludge dewatering is not thorough, and the sludge treatment equipment is difficult to meet the environmental protection requirements. However, at this stage, the municipal sludge dewatering agent developed by Works Chemical can effectively solve this problem, dewatering the sludge to 40%-60% moisture content, forming a sludge cake that can be reused as resources.

Due to the continuous development and progress of the production and processing industry in the market, industrial water consumption has increased rapidly. Sludge dehydrating agent can purify water resources and improve the utilization efficiency of water resources. This is very helpful for wastewater treatment. Sludge dewatering agent is a kind of polymer dewatering coagulant, which can flocculate sludge quickly and reduce sludge by equipment.

一. Advantages of sludge dehydrating agent (compared with lime, iron salt and aluminum salt)

1. Reduce the amount of sludge.

2. The use of sludge dehydrating agent, the water content of the sludge can meet the requirements of reuse, and the sludge can turn waste into treasure.

3. Sludge dewatering agent is especially suitable for dehydration under vacuum negative pressure, and the amount of water removed per hour will increase.

4. The dehydration speed is fast, and the clarification of the filtered water can reduce the difficulty of subsequent wastewater treatment.

5. After dehydration, the volume of filter cake will be greatly reduced.

6. The weight of filter cake dehydrated with sludge dehydrating agent is greatly reduced.

7. Without any inorganic salt, the mud cake will not harden after deep and high drying.

8. After adding sludge dehydrating agent, the filter material will hardly adhere to the filter equipment, reducing the cost of equipment cleaning.ge to the filter cloth; It is conducive to the subsequent incineration of sludge, brick making and composting. For sewage sludge treatment enterprises can save costs, benefits without harm.
