摘　　要：该研究主要以呼和浩特市章盖营污水处理厂二级再生水为研究对象,利用因子分析法的降维及评分功能,在进行大量水质检测的基础上,对再生水水质进行合理的评价并探究其随季节变化特征,同时提出合理的再生水利用途径。结果表明:夏季再生水水质要明显好于其他季节,再生水水质具有明显的季节间和日间的不稳定性;污水水质夏季明显优于冬季,并且随季节波动明显;同时,针对呼和浩特地区再生水利用现状为再生水高效合理利用提出可行性建议。Mainly using secondary recycled water of Hohhot Zhanggaiying sewage treatment plant as the research object,on the basis of a large number of reclaimed water quality testing,the factor analysis method of dimensionality reduction and score function were used to carry on the reasonable evaluation and explore the seasonal variation characteristics,and put forward the reasonable use way of recycled water.The results showed that:the reclaimed water quality in summer was significantly better than that in other seasons,and reclaimed water had obvious seasonal and dayly instability.Sewage water was better in summer than in winter and seasonal fluctuations were obvious.This paper gives the efficient and reasonable utilization suggestions for the using of reclaimed water in Hohhot.
