Due to the acceleration of China's urbanization process and the rapid development of industry and agriculture, a large number of sludge is produced every year. The composition of sludge is extremely complex, and it is a complex heterogeneous mass composed of organic debris, bacteria, inorganic particles and colloid. Due to its high natural moisture content and poor mechanical properties, sludge cannot be directly used in engineering. In addition, sludge also contains a variety of heavy metals, organic pollutants, pathogenic microorganisms, parasitic eggs and other harmful substances, if not harmless treatment, will cause secondary pollution to the environment. How is this sludge disposed of properly? This is the sludge solidification sludge solidification is by adding curing agent to the sludge, through the chemical reaction to make it into non-flowing or solid solidification, so as to transform harmful pollutants into substances with low solubility, low toxicity and low mobility. After curing, the product has higher strength and lower water permeability, which can replace sand, clay and other building materials, so that the sludge can be fully utilized and prevent the occurrence of secondary pollution to the maximum extent. The application of sludge solidification technology not only solves the problems of sludge stacking, land filling and causing landfill engineering accidents, but also can achieve the purpose of sludge disposal and resource utilization. It is a new technology suitable for China's national conditions from both technical and economic aspects
