Study on Treatment of Printing and Dyeing Wastewater with ABRCirculated Moving Carrier Membrane Bioreactor
A laboratory-scale study of the treatment of printing and dyeing wastewater was carried out using the combined process of ABR and circulated moving carrier membrane bioreactor. ABR was maintained at a hydraulic retention time (HRT) of 8.5 hours and at a temperature of indoor temperature. The experiment is consisted of two parts: The fist section is that using amylum as sizing agent to inspect the reactor treat capability; When the influent COD was 1585 -5301mg/L, the effluent COD was 42 mg/L overall 97％ of COD removal. The average removal rates of COD, NH4-N, and color were 97％, 90％, 94％. The second section is that using PVA as sizing agent to inspect mainly on the effect of hydrolysis and acidgenisis of ABR and the organic removal effect of the system. Results showed that excellent effluent quality could obtained after the degradability of the refractory wastewater has been improved greatly in ABR.
