TREATMENT OF WASTE WATER

摘要

PURPOSE:To keep high mixed liquor suspended solid (MLSS) concentration in an aeration tank and to enable an efficient activated sludge treatment by aerating an activated sludge aeration tank with a gaseous mixture of air and ozone, enhancing flocculation property of the mixed liquor suspended solid (MLSS) to separated and precipitate the sludge in a precipitations tank by a easier manner. CONSTITUTION:In an activate sludge aeration tank where the mixed liquor suspended solid (MLSS) concentration is made to >=5000mg/l and also the waste liquid is treated at >=3kg/cm<3>.day BOD volume load in the aeration tank, the tank is aerated with the gaseous mixture of air and ozone.
