Research on the Characteristic of Dyeing-Printing Wastewater Treatment with Micro-Aerobic Granular Sludge
Abstract:
In order to treat dyeing-printing wastewater, the experiment took reflux tank, self-regulating control valve making of medical infusion, air flow meter, dissolved oxygen instrument, aerator pumps and aeration equipment under the micro-aerobic condition by IC reactor. The result indicates that the concentration of dissolved oxygen at 0.3 ~ 0.5 mg/L, increasing the load of mixed water and in-flow water by 25% and 7% separately in turn, the experiment is feasible. When COD load reached 2188.2 mg/ L in the mixed wastewater, the components in printing and dyeing wastewater are poisonous and repressive to the grown of granular sludge, which also illuminates that the function of micro-aerobic granular sludge treating printing and dyeing wastewater is limitary. When the influent load reached 4655.1mg / L or so, dissolved oxygen was 0.3 ~ 0.5mg / L, HRT was 6h, the reactor worked best, this moment, the removal rate of COD could reach 85.8%.
