By using heat pump low-temperature drying technology,the moisture content of sludge in a chemical enterprise's sewage treatment plant was reduced from 80%to 30%,achieving reduction and stabilization of sludge.The hazardous properties of the dried biochemical sludge were identified in order to achieve the best treatment and disposal method.The results show that the biochemical sludge does not belong to hazardous waste and can be disposed as general solid waste.The results of this study provide ideas and references for the identification of biochemical sludge,and provide a basis for the daily management of enterprises.
