Abstract: The efficiency of wastewater treatment decreases due to the low temperatures in the winter season in most parts of China, which results of the increase of the operation cost, and hence an adverse impact on the environment and damages to human health. The recent advances on the biological wastewater treatment technologies at low temperatures were sammanzed. In terms of the morphological types of sludge(e.g.2 floc sludge, anaerobic granular sludge and aerobic granular sludge), their advantages and disadvantages were compared and the trends on biological wastewater treatment at low temperatures were prospected.

Key words: low temperature, wastewater treatment, floc sludge, anaerobic granular sludge, aerobic granular sludge
