| Abstract: | In the article domestic wastewater is adopted as a sample for experiment . Removal efficiency of natural freezing on COD sources and NH3-N is analyzed on the basis of the experiment by the man-made natural climate environment.The experiment results show that the natural freezing is an effective method for removing pollutants in the sewage. By the natural freezing, more than 80 percent of COD and more than 90 percent of NH3-N could be removed. The method of the natural freezing has features of simple process, easy operation, low cost and high efficiency. Especially, it is suitable for the climate of the low temperature and the long winter in the northern part of our country. |
