摘要
针对川中丘陵地区水库原水氨含量高及现有水厂处理工艺现状,研究了折点加氯除氨工艺,经过生产应用验证,采用折点加氯对原水氨(以N计)的去除率为93.5%~98.1%,去除效果显著,且消毒副产物三卤甲烷含量满足标准要求。本研究可为生产情况相似的供水生产企业提供借鉴。
In view of high content of ammonia in the raw water of reservoirs in the hilly areas of central Sichuan and the current status of the existing water plant treatment process,the break point chlorination ammonia removal process was studied.Through verification by production application,the ammonia removal rate of raw water(calculate by N)by break-point chlorination was 93.5%~98.1%,with significant removal effect,and the content of disinfection by-product Trihalomethane met the standard requirements.This study can provide reference for water supply production enterprises with similar production situations.
