With the increase in urban society and population , the increasing number of sewage emissions will produce a more urban sewage sludge . How to properly dispose of the sludge is the global issues of mutual concern , the consensus today is the utilization of the resources of the sludge , controlling pollution at the same time turning waste into treasure . In this paper, drying , grinding and incineration treatment sludge ; extrusion and roasting prepared sludge incineration ash sintered body ; meet sintered common brick \dosage , the sintering temperature of the sintered body physical and mechanical properties (bulk density , compressive strength , linear shrinkage rate ) and wind of performance ( water absorption , saturation coefficient , frost resistance ) . The results show that : the sludge incineration ash sintered body both in appearance and quality , or the smell of the roasting process gas emissions are better than dry sludge sintered body ; sintering temperature of 1050 ° C , sludge incineration ash sintered blank body intact appearance quality , and sintered body volume density decreases with the increase of sludge incineration fume , compressive strength decreases , the decrease in linear shrinkage , water absorption increases , saturation coefficient constant body appearance after freezing and thawing intact , SEM analysis result of FIG : an increase in the number of pores and pores inside the sintered body , the volume increases ; sludge incineration fume 40% , the sintering temperature of 990 ° C and the sintered body showing owe fire phenomenon , a sintering temperature of 1080 ° C the appearance of the sintered body of poor quality, the showing excesses phenomenon . With the sintering temperature , sintering the preform increased volume density , compressive strength increases, a constant drying line shrinkage bus shrinkage is reduced , the water absorption decreased , decrease in saturation coefficient preform appearance intact after freezing and thawing , SEM analysis diagram : a decrease in the number of pores and pores inside the sintered body , the volume is reduced ; considering the the sintered body 's physical , mechanical properties and resistance to weathering performance , sludge incineration ash ash 40% , the sintering temperature of 1050 ℃ prepared sintering the green body , not only the utilization of sludge and gangue waste reaches the maximum 80% , and to meet the sintered common brick \
