Abstract :
Dying-printing wastewater is treated under micro-aerobic situation in IC reactor, the experiment uses 10%PAC and 0.05%PAM, with the ratio of the raw water to flocculent 400:1, after coagulating sedimentation, the biochemical performance of the wastewater is greatly improved, up to about 0.22; when influent loads is improved to about 4655.1mg/L, dissolved oxygen concentration 0.3mg/L and HRT 5h, the COD removal rate can up to 85.8%, micro-aerobic granular sludge has been relatively mature in this phase, the increasing of dissolved oxygen concentration in the micro-scope does not affect the performance of micro-aerobic granular sludge under high influent loads.
