The nutrient composition of activated sludge for the treatment of waste water is prepd. by mixing fermentive materials, inoculated rice bran with bacillus substillus and bacillus natto, with the cultured material of yeast, and then adding some quantity of MgSo4, FeSo4 and CaCl2 to their mixture. In the process, COD, BOD and a pigment contained in waste water are decomposed within about 12-24hr, and an alkaline waste water of PH 7.0-10.5 can be effectively treated with the process.
