Abstract:
The treatment of the PVA desizing wastewater by coagulation-dominant bacteria active sludge process has been studied in small scale test. PVA degradation dominant bacteria have been inoculated into the active sludge. As a result, the removal rate of CODCr is 93.52% and the treatment effect can reach the secondary standards of GB 4287—1992.
