摘要
采用生物接触氧化法对北京某水库的微污染水源水进行了去除NO2-—N的试验研究。结果表明,运行期间,生物接触氧化柱(简称生化柱)对NO2-—N的去除率最高可达98%。水温对NO2-—N的去除效果有很大影响,水温越高,生化柱去除NO2-—N的效果越好;在原水水温相同的条件下,原水中NH4+—N浓度越低,生化柱去除NO2-—N的效率越高;原水中NO2-—N浓度越高,生化柱去除NO2-—N的效率越高。
This paper related to a study of removing nitrites contained in micro-polluted source water of a reservoir in Beijing. The bio-contact technology was used and the results showed that up to 98% removal of NO^-_2-N had been obtained. Factors affecting nitrites removing were investigated, such as temperature and initial concentrations of ammonia and nitrites in the water. :Thi
