摘要

我国北方地区农村生活污水处理受低温影响严重。为解决此问题，通过低温驯化得到在8℃下对污水有较好处理效果的活性污泥，并对其污水处理效果进行分析。结果表明，用干重浓度为3.4 g?L-1的已驯化污泥对农村生活污水进行处理时，COD去除率最高为84.97%，出水COD最低为89.51mg?L-1，达到农田灌溉水质标准（GB 5084-2005）的最短处理时间为8d。与非驯化的污泥相比，驯化后活性污泥对污水的COD去除率提高了23.14%，这为北方地区农村生活污水处理提供了良好的技术支持。

Abstract:

Rural domestic sewage treatment in northern of China is seriously affected by low temperature. In order to solve this problem, the activated sludge with good treatment effect on sewage at 8℃ was obtained by low temperature domestication, and its sewage treatment effect was analyzed. The results showed that when the domesticated sludge with dry weight concentration of 3.4g?L-1 was used to treat rural domestic sewage, the highest COD removal rate of the rural domestic sewage was 84.97%, the lowest COD of the effluent was 89.51 mg?L-1, and the shortest treatment time of reaching irrigation water quality standard of farmland (GB 5084-2005) was 8 days. Compared with the non-domesticated sludge, the COD removal rate of sewage after the activated sludge acclimated increased by 23.14%, which provided good technical support for rural domestic sewage treatment in northern of China.

Key words: low temperature rural sewage sewage treatment activated sludge
