Municipal sludge is the sediment produced in the water treatment process of municipal sewage treatment plant. It not only contains a large number of microorganisms, organic matter and rich nutrients such as nitrogen and potassium, but also the content of heavy metals and pathogenic microorganisms exceeds the standard. At present, the moisture content of urban sludge is mostly about 80%. At present, the new sludge dewatering agent independently developed by Works Chemical can effectively solve this problem, dewatering the sludge to the moisture content of 40%-60%, forming a recyclable sludge cake as a municipal resource sewage. Mud treatment has laid a good foundation. Due to the continuous development and progress of the production and processing industry in the market, industrial water consumption has increased rapidly. The new sludge dehydrating agent can effectively purify water resources and improve the utilization efficiency of water resources. This is very helpful for wastewater treatment. The new sludge dewatering agent is a polymer dewatering coagulant, which can be used to flocculate sludge quickly and reduce sludge.
Advantages of new sludge dehydrating agent: (compared with lime, iron salt, aluminum salt)
1. reduce and increase the amount of sludge.
2. the use of new sludge dehydrating agent (sludge dehydrating agent), sludge water content to meet the requirements of reuse, sludge waste into treasure.
3. the new sludge dewatering agent is especially suitable for vacuum negative pressure dehydration, the water removal per hour will increase.
4. dehydration speed is fast, the filtered water is clear, which can reduce the difficulty of subsequent wastewater treatment.
5. The volume of filter cake will be greatly reduced after dehydration.
6. The weight of filter cake after sludge dewatering agent is greatly reduced.
7. does not contain any inorganic salt, mud cake will not harden after drying.
8. After adding a new type of sludge dehydrating agent, the filter material will hardly adhere to the filtration equipment, reducing the cost of equipment cleaning.
