<P>PROBLEM TO BE SOLVED: To provide a treatment method of organic wastewater and organic sludge and its treatment equipment which can economically clean the organic wastewater generated in large quantities at a fishing port, a fish market and an onshore fish farm or the like, and treat surplus organic sludge after the cleaning. <P>SOLUTION: The treatment equipment of the organic wastewater and the organic sludge is provided with a bubble separation tank 5 into which the wastewater, from which solid materials such as a piece of fish or the like are removed, is introduced, a bubble generation means 16 installed in the bubble separation tank 5 for generating fine bubbles in the wastewater, a membrane separation activated sludge treatment tank 10 into which the bubbles generated in the bubble separation tank 5 are introduced, and a fish farming tank 18 into which the surplus organic sludge generated in the membrane separation activated sludge treatment tank 10 is introduced and in which benthos are bred. The organic wastewater generated at the fishing port, the fish market and the onshore fish farm or the like is treated with the activated sludge in the membrane separation activated sludge treatment tank 10 and the surplus organic sludge generated thereby is introduced into the fish farming tank 10. The surplus organic sludge is used as feed for the benthos so that the volume of the sludge is reduced by digestion. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
