<p>A treatment equipment for organic waste water and organic sludge, comprising foam separation tank (5) in which waste water after removal of solid matter such as fish meat piece is introduced; bubble generating means (16) disposed in the foam separation tank (5) and capable of generating fine bubbles in the waste water; membrane separation active sludge treating tank (10) in which the foam generated in the foam separation tank (5) is introduced; and culture water bath (35) in which excess organic sludge having occurred in the membrane separation active sludge treating tank (10) is introduced and in which benthic organism (32) is raised. Organic waste water having occurred in fishing ports, fish markets, land cultivation farms, etc. is subjected to active sludge treatment in the membrane separation active sludge treating tank (10). Thus generated excess organic sludge is introduced in the culture water bath (35), so that the excess organic sludge is digested, reduced in weight and disposed of as feeding stuff (feed) of benthic organism. As a result, purification treatment of organic waste water occurring in large volume in fishing ports, fish markets, land cultivation farms, etc. and treatment of excess organic sludge after the purification treatment can be carried out in economic advantage.</p> |
