-28- ABSTRACT A sewage purification method according to the invention includes a first process in which at least two kinds of flocculants are introduced in sewage for stirring and mixing therewith so as to float and settle inorganic and organic materials. The first process is sequentially repea- ted more than one time. In a first process, at least two kinds of flocculants are introduced in sewage for stirring and mixing therewith so as to float and settle inorganic and organic materials. Next, and in a second process, at least three kinds of flocculants are introduced into supernatant obtained in the first process for stirring and mixing therewith so as to float and settle remaining inorganic and organic materials. At least one of the first and second processes is sequen- tially repeated more than one time. In the above way, middle water, drinking water and super-pure water can be obtained from sewage. Purification of exhaust gas is also possible by introducing such exhaust gas in one of the above process.
