Sludge is a solid sedimentary substance produced during sewage treatment. According to the source of sludge, it can be roughly divided into municipal sludge, pipe network sludge, river and lake sludge, and industrial sludge. Unless otherwise specified, general sludge Refers to municipal drainage sludge.
Sludge is produced by a series of physical, chemical and biological treatment processes. It is a solid substance produced after various levels of sewage treatment. Municipal drainage sludge is produced by sewage treatment plants through sludge concentration, sludge dehydration and sludge drying. and other complex processes.
The sludge is prepared through appropriate proportions, granulation, and high-temperature calcination to prepare ceramsite, which can be used as building materials and realize the resource disposal of sludge; because the prepared ceramsite is calcined at a high temperature of 1050-1200°C, harmful materials will appear Decomposition can make sludge harmless; ceramsite can wrap and solidify heavy metals, which can stabilize sludge; at high temperatures, the water and organic matter in sludge escape in the form of gas, which can reduce sludge. change. Compared with other sludge treatment and disposal methods, landfill methods have been restricted by policy. Sludge fertilizer production is limited by the market. Sludge drying and incineration is limited by fly ash. Sludge preparation of ceramsite is a way to completely turn waste into efficient access to resources.
Henan Zhengzhou Mining Machinery Co., Ltd is committed to the utilization of solid waste resources. The company's corporate technology center has long-term cooperation with Zhengzhou University. It has a skilled process route and a professional mechanical design team that can handle all processes from design, construction, installation, and debugging, and research and develop kaolin clay.
