Title: Method for treating sludge of purifying tank
Inventor: YASUDA YUJI
IPC: B01D61/16
Filed: 1990-11-15
Abstract: PURPOSE:To treat the quality of the separated liquid from the sludge of a purifying tank without applying biological treatment to obtain dischargeable water quality by injecting a flocculant in the sludge of the purifying tank, and subsequently subjecting the sludge to the separation treatment due to an ultrafiltration membrane with a fractionation mol.wt. of 10000 or less. CONSTITUTION:A flocculant 2 is injected in the sludge 1 of a purifying tank 11 in a flocculant mixing tank 3 to perform flocculation reaction and the treated sludge is introduced into an ultrafiltration membrane module 4 to be separated into separated sludge 5 and a separated liquid 6. About 100% of SS is blocked (removed) in the ultrafiltration membrane module 4 to transfer to the sludge 5 and the greater part of BOD is also removed and the concn. of BOD in the separated liquid 6 becomes about 30ppm or less. The fractionation mol.wt. of an ultrafiltration membrane must be 10000 or less but the material quality of the membrane and a membrane module type are not limited. As the material quality of the membrane, a commercial ultrafiltration membrane composed of polyacrylonitrile or polyolefin may be used and, as the membrane module, any type such as a tube type or a hollow fiber type may be used. The separated sludge 5 is treated in a sludge treatment process. As the flocculant, there is aluminum sulfate or ferric chloride.
