The chemical and mineral composition of bottom sediment in Suzhou Creek was analysed. The technological parameter for sintering clay ceramisite by the use of bottom sediment as primary raw material was discussed. The origin of noxious constituents in sediment and ceramisite was explored, in the meantime, the quantitative analysis for noxious constituents was carried out. The results show: by the adjustment of elemental compositions of bottom sediment in Suzhou Creek 700 # clay ceramisite can be produced. By sintering the bottom sediment in Suzhou Creek, heavy metal contamination can be solidified in ceramisite, and the pollution of the environment will not happen.
