APPARATUS AND METHOD FOR TREATMENT OF TEXTILE WASTEWATER USING ANAEROBIC-AEROBIC BIOFILTER AND POST OZONE PROCESS

摘要

PURPOSE: The suspended material contained in the dyeing wastewater is eliminated to the utmost. The load of the biofilter process of this process and generation rate of the sludge can be reduced. In the anaerobic aerobic biofilter process, the contact area between microorganism and the processing water are broadened with the biofilter filtering. CONSTITUTION: The processing unit of the dyeing wastewater. With the high speed sedimentation filtration(10) for the constellation of effluent not constant and eliminating the suspended material of the dyeing wastewater having with the large quantity content. With the anaerobic biofilter tank(20) which processes the processing water transferred to from the high speed sedimentation filtration by using anaerobe. With the biofilter tank(30) in which anaerobic or aerobic is selected selectively according to the property of the dyeing wastewater and processing the processing water transferred to from the anaerobic filter bath it selective.
