Sludge discharged from sewage treatment plants is disadvantageous in transportation and disposal due to its high water content, large volume, and susceptibility to putrefaction and odor. Therefore, dewatering is often required to reduce the moisture content of the sludge, reduce the volume of the sludge, and reduce transportation costs. The content of available substances after the sludge is concentrated is relatively increased, which is beneficial to the subsequent treatment and utilization of the sludge.

Offshore areas are usually disposed of by throwing of mud from the sea, while inland areas are usually stockpiled to recover the land after natural evaporation and consolidation and sedimentation, which natural process lasts for several years to several decades. In order to accelerate the consolidation of the slurry, a certain conditioning agent is generally added for conditioning, and then a mechanical dehydration mode is adopted for reducing the volume and improving the strength, so that the subsequent transportation and use are easy.

In the processes of reduction, resource treatment and treatment of various types of slurry, a certain amount of conditioner is often required to be added to condition the slurry firstly, so that the post-treatment effect or efficiency is improved. However, the problems that the conditioner is blocked and the like can not be accurately added, the treatment effect is influenced, and cost fine control can not be realized generally exist at present.
