To reduce the sedimentation ratio of sludge, the following methods can be taken:
1.Improve sludge characteristics: The sedimentation performance of sludge can be improved by adjusting parameters such as pH, viscosity, and particle size of sludge. Suitable conditioners and chemicals can help improve the sedimentation performance of sludge.
2.Optimize sludge concentration: control the sludge concentration to avoid excessive concentration leading to poor sedimentation effect. Dilute the sludge appropriately so that its concentration is within the optimal range.
3.Use of co-settlers: Adding some co-settling agents, such as polymer flocculants or flocculation aids, to the wastewater treatment process can help increase the settling rate of the sludge.
4.Optimize the design of the sedimentation tank: Reasonably design the structure and size of the sedimentation tank to ensure that the sewage stays in the sedimentation tank for a long enough time, which is conducive to the full sedimentation of sludge.
5.Enhanced stirring and mixing: Intensified stirring and mixing in the sedimentation tank can help evenly distribute the sludge and accelerate the sedimentation rate.
Through the above methods, the sedimentation ratio of sludge can be effectively reduced, and the sedimentation effect of sludge can be improved, so as to improve the operation efficiency of sewage treatment system.
