Abstract

PURPOSE: To keep the treating performance of activated carbon treatment apparatus constant as well as promote the generation and growth of activated sludge is aeration chamber by introducing polluted water deprived of coloring matters and SS from the activated treatment apparatus, together with saturated activated carbon, into the aeration chamber.
CONSTITUTION: The polluted water 12 is introduced into the separation chamber 9 tp separate it into liquid and solids, and then the liquid is sucked in the lower end of the vertical pipe 13 and flowed into the activated carbon treatment apparatus 1 through the inflow pipe 15. the polluted water treated in the apparatus 1 is flowed down, along with saturated activated carbon, to the aeration chamber 2 below the apparatus 1 for aeration with air from the diffuser 16, during which saturated activated carbon becomes the uncleus of activated sludge during aeration from the diffuser 16, whereby promoting the generation and growth of activated sludge. Furthermore, the activated sludge nucleus becomes so great specifically that its separability by sedimentation is raised. Then, aerated liquid introduced into the sedimentation chamber 8 is subjected to sedimentation and separation, sterilized in the sterilizing chamber 17, and then released from the discharge pipe 18.
