Abstract

HIGH-LOAD TREATMENT AT A CODcr VOLUME LOAD OF 1.0 KG/M3/D OR MORE OR A BOD VOLUME LOAD OF 0.5 KG/M3/D OR MORE IS PERFORMED BY A MULTISTAGE ACTIVATED SLUDGE PROCESS UTILIZING PREDATION BY ANIMALCULES. IN ORDER TO IMPROVE TREATMENT EFFICIENCY AND TREATED WATER QUALITY AND DECREASE THE SLUDGE VOLUME, ANIMALCULES OF THE FILTER-TYPE PREDATORS IS MADE DOMINANT ACTIVELY, AND THE GROWTH OF ANIMALCULES OF THE AGGREGATE PREDATORS THAT DETERIORATE TREATED WATER QUALITY IS REDUCED. ORGANIC WASTEWATER IS BIOLOGICALLY TREATED WITH BACTERIA IN A FIRST BIOLOGICAL TREATMENT TANK (1). FIRST BIOLOGICALLY TREATED WATER CONTAINING A DISPERSED BACTERIA FROM THE FIRST BIOLOGICAL TREATMENT TANK (1) IS TRANSFERRED TO A SECOND BIOLOGICAL TREATMENT TANK (2) AND TREATED THEREIN TO BECOME A SECOND BIOLOGICALLY TREATED WATER. THE SECOND BIOLOGICALLY TREATED WATER IS SUBJECTED TO SOLID-LIQUID SEPARATION IN A SETTLING TANK (3). SEPARATED SLUDGE IS RETURNED TO THE SECOND BIOLOGICAL TREATMENT TANK (2). THE SECOND BIOLOGICAL TREATMENT TANK (2) CONTAINS A CARRIER (22) FOR SUPPORTING ANIMALCULES.
