Abstract
PURPOSE: To enable treatment of waste water containing polyvinyl alcohol and/or starch by use of a treating agent consisting of calcium aluminate and calcium oxide.
CONSTITUTION: A combination of calcium oxide and calcium aluminate is used as a treating agent. The agent is expressed by a general formula XCaO.YAl2O3, where the ratio X/Y is usually between 3/1 and 3/5. The ratio of calcium oxide to alumina (CaO/Al2O3) is kept in the range of 1/9 - 9/1, preferably 7/3 - 8/2. The waste water containing polyvinyl alcohol and/or starch is treated by contacting it to the treating agent. The method is applicable to various waste water, particularly desizing waste water in textile industry and surface sizing waste water in paper industry.
