Development and Research Status of Semiconductor Materials
In recent years,in order to achieve the"double carbon"goal,more and more attention has been paid to the resource utilization of solid waste.With the development of the liquor industry,a large amount of wastewater sludge is produced in the brewing process,and the dis-tiller's grains sludge is rich in organic matter and has ecological and economic utilization value.It is becoming more and more urgent to explore the disposal methods of distiller's grains sludge reduction,stabilization,harmlessness and resource utilization.At present,the utilization meth-ods of distiller's grains sludge mainly include landfill,incineration,composting and building materials.The use of distiller's grains sludge to prepare permeable bricks,and the study of their mechanical properties,permeability and water purification properties can solve the problem of sludge disposal and play an important role in the construction of sponge city.
