序批式生物膜反应器与生态塘联合工艺处理低温生活污水研究

In the low temperature region, some even all the indicators of the low temperature wastewater treated by the traditional activated sludge process or biofilm process could not be achieved the wastewater discharge standards. The treatment of low temperature wastewater by combination process of sequencing batch biofilm reactor (SBBR) and ecological ponds was studied in the paper. In the low-temperature process and specific conditions, the effluent treated by the secondary treatment of the sequencing batch biofilm and the advanced treatment of the ecology pond could reach the sewage discharge standards.
