Analysis For Process And Treatment-disposal Technic Of Municipal Sewage Sludge

With China's rapid development of urbanization, rapid growth of urban population, witha corresponding number of urban sewage treatment increasing in the treatment of sewagesludge generated during the rapid increase in the number. If the city without proper sewagesludge treatment and disposal, the city will cause great harm to the environment.As people living standard rise ceaselessly, right living environment has also put forwardhigher request. The original urban sewage sludge disposal ways already cannot satisfy socialdevelopment and people's needs. This thesis based on urban sewage sludge properties,production status, urban sewage sludge treatment situation, combining Nanhai sewage sludgetreatment engineering, and raised the urban sewage sludge disposal means uses sludge drying,and half the sludge drying after selection and living garbage mixed burn of the scheme.Therefore, this paper studies and discusses the content:This thesis uses the experiments to analyze and appraise the sludge characteristics inNanhai sewage treatment plant.This thesis based on recycling economic principle, by analyzing the sewage sludgetreatment and disposal technology and combining with the sewage sludge treatmentengineering situation of Nanhai,recommend the use of sludge semi-dry sludge of choice andafter the blending process waste line.In this thesis, hot dry home and abroad through the analysis and comparison ofequipment,combining with the sewage sludge treatment engineering situation of Nanhai,recommend its selection of thermal drying equipment.
