The Treatment of High Concentration Fixer Wastewater Using Three-Stage Biological Contact Oxidation-Hydrolytic Acidification Process

摘要

Trough the contract of three wastewater treatment process, activated sludge process, two-stage biological contact oxidation process and three-stage biological contact oxidation-hydrolytic acidification process, three-stage biological contact oxidationhydrolytic acidification process is used to treat the high concentration fixer wastewater, treating quantity 300L/d, after the treatment, the removal rates of COD reach 66.36%. The running results show that the treatment efficiency of the technology is stable, tolerable in shock load. Furthermore, the altering currents of these factors such as volume loading, centigrade, pH, biota, etc, are analyzed.
