Case Study on Identification of Hazardous Characteristics of Biochemical Treatment Sludge from Sewage Treatment Plant
In this paper,the hazardous characteristics of the biochemical treatment of sludge in one sewage treatment plant were identified based on the production process,raw and auxiliary materials and other data provided by this sewage treatment plant.By analyzing the production process and the original materials,combined with the analysis of the tested results of preliminary screening samples,the nonexistent dangerous characteristics of biochemical treatment sludge in the sewage treatment plant were eliminated.And then scheme of sampling,testing and testing result judgment were formulated to obtain the testing results of the samples,and after comprehensive analysis,the judgment of solid waste properties of biochemical treatment sludge was given.This paper provides a technical reference for sewage treatment plants and ecological environment authorities to carry out corresponding solid waste environmental management.
