Due to the large amount of organic pollutants in the urban sludge or silt, the moisture content is relatively high, so it is almost impossible to be air-dried or disposed innocently in the pit. Such sludge pits serve as incubators for sewage and all manner of contaminating bacteria, emitting foul odors in the sunny days and producing foul water in the rainy days. Over and over again, the large sludge pit becomes a place of death, with no plants or animals living there, leaving a great safety hazard. With the development and expansion of the city, the harm of these sludge dumps gradually appears. Therefore, it is very important to treat these sludge pits by effective means to stabilize and recycle them. Urban sludge treatment equipment, sludge solidification, sludge solidification, municipal sludge treatment and sludge solidification equipment, silt solidification equipment can improve the relevant chemical and physical properties of the sludge, reduce its moisture content, improve its carrying capacity, permeability, etc., also can adjust the different disposal of sludge and sludge disposal plan, to meet the requirements of the characteristics of sludge recycle. In this way, not only can be safely disposed of the sludge or silt storage, but also can be disposed of a large number of sludge constantly produced, according to different requirements for sludge resource utilization such as construction backfill soil, basic soil, green soil and so on.
