<p><P>PROBLEM TO BE SOLVED: To provide a treatment method for treating sludge using a dissolving facility providing a dissolving performance equal to that of the dissolving method using the conventional dissolving facility, and usable even in a narrow space, when efficiently dewatering a large amount of sludge from a sewage treatment facility. <P>SOLUTION: A dispersion type polymer coagulant and dilution water are fed into a pipe to be brought into contact with each other. The mixed diluted liquid is fed to a sludge coagulation/mixing tank or a mechanical condensing facility in the sludge treatment facility, to coagulate or condense the sludge produced from sewage biological treatment. That is, the coagulated sludge is transferred to a belt type condenser from the sludge coagulation/mixing tank for condensing, or the diluted liquid is directly fed to a centrifugal condenser for condensing operation. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
