摘要
现有国家标准中没有适用于焦化废水中硝酸盐氮和亚硝酸盐氮的测定方法,焦化废水水质评价和焦化废水处理系统运行无法获得准确数据和生产指导。戴氏合金还原一中和滴定法的制定解决了实际工作中的这一问题,通过准确度、精密度评价和多年生产中各数据间关联性检验,证明该方法能较好地适用焦化废水水质评价和焦化废水处理系统生产的工作需要。
Method for determination of the existing national standards is not suitable for nitrate nitrogen and nitrite nitrogen in coking wastewater of coking wastewater, water quality assessment and coking wastewater treatment system is unable to obtain the accurate data and production guidance. Formulated Dai alloy reduction neutralization titration method to solve this problem in the practical work, through the correlation test between the data accuracy, precision evaluation and production for many years, that the method can be applied to evaluate the quality of coking wastewater and coking wastewater treatment system production work needs is proved.
