METHOD OF REDUCING CODCr IN HIGH CONCENTRATION SILICONE WASTE LIQUID

摘要

PPROBLEM TO BE SOLVED: To provide a method of easily and stably reducing CODSBCr/SBin high concentration silicone waste liquid containing CODSBCr/SBfor 500 mg/l or more to the level of 100 mg/l or less. PSOLUTION: To the high concentration silicone waste liquid, pH adjustment, Fenton treatment, deposition and flocculation treatment by making pH high, activated sludge treatment and flocculation treatment are executed in the order. Activated carbon adsorption treatment is executed finally, and CODSBCr/SBof the high concentration silicone waste liquid is reduced. PCOPYRIGHT: (C)2011,JPO&INPIT
