摘要：

研究了在pH为10.5的硼砂-氢氧化钾缓冲溶液和乙醇的增敏作用条件下,偶氮氯膦Ⅰ与钙镁的吸收特性,建立了多波长吸光光度法同时测定钙镁的方法。采用两种矩阵算法对实验数据进行处理,并对结果进行比较和分析。钙镁质量浓度在0～1mg/L范围内用方法2能得到准确结果。

Abstract:

EGSB ( expansile granular sludge bed) is used in combination with anaerobic biological process and activatedsludge aerobic process to treat highly concentrated amylum production wastewater. The water quality of the final effluentcan meet the First Grade of the National Effluent Discharge Standard. The engineering example shows that this processhas many advantages,such as low investment,less land,and stable treatment efficiency. The sources of energy can be recovered.Therefore,this process has great value of being popularized.

Key words: multi wavelength, spectrophotometry, calcium, magnesium, modified matrix algorithm
