摘要: The chemical compositions changes for waste activated sludge at different freezing speeds were analyzed via FTIR spectra. With a high speed of freezing, the are little influenced by action ice formation, which with low largely affected. prerequisite sufficient dewaterability improvement is found as global floc migration owing to front releases some ECPs (basically cellulose) from and after resulting cake structure ultimately.
