Research progress of source and release characteristics of main pollutants from sludge thermal drying process
In the sludge thermal drying process,the main pollution factors are condensed wastewater and non-condensing gas from water evaporation and condensation,which contain typical pollution components including COD,ammonia nitrogen,hydrogen sulfide,benzene,toluene,ethylbenzene,and xylene(BTEX)as well as some common malodorous components,having a great impact on the drying workshop.Current research on pollutants from the sludge thermal drying process was summarized,and the main factors that influence pollutant generation and release were analyzed.The release mechanism of typical pollutant components was concluded.It is expected to provide suggestions on the optimization of the sludge thermal drying technology.
