摘要
试验研究了折点加氯去除低温生活污水中氨氮的加药量、pH值、反应时间等工况条件以及工程应用设施,结果表明,采用次氯酸钠折点氯化的方法深度处理氨氮,操作方便,反应迅速完全,脱氮率高,出水氨氮1 mg/L以下,达到排放标准。
The dose of the NaCIO, react time and the equipment function were studied in the experiment of NaCIO to remove ammonia-N. The results show that this new method can remove the more ammonia-N effectively and react completely. Moreover, we got less investment about equipment in the advanced wastewater treatment.
