Title: Treatment of sewage and equipment thereof
Inventor: TODA YASUKAZU
IPC: C02F1/24
Filed: 1988-04-27
Abstract: PURPOSE:To reduce sludge disposal cost and to miniaturize an equipment by performing pressure floatation in a pressure floatation tank and utilizing one part of floated sludge for sludge concn. control in a batch reaction tank. CONSTITUTION:When injecting high-pressure water wherein air is solubilized from the bottom part in a pressure floatation tank 31, fine foams are generated by sudden decompression and the fine foams are stuck to floating sludge bloc and raised and these are removed by the sludge collecting mechanisms 40a, 40b. By such a way, since dust collection is not performed in water, sludge can be aerobically recovered in a state of high sludge concn. and both solid- liquid separation and sludge concentration can be simultaneously performed and therefore a sludge concentration tank is made unnecessary. Therefore sludge volume carried out as excess sludge is diminished and sludge disposal cost can be reduced. Further since the concn. of sludge sent to a batch reaction tank 20 as return sludge is high, the batch reaction tank 20 and an equipment thereof can be miniaturized.
