人类生活用水处理用化学制品.焦磷酸四钠 - The high - efficiency cleaning agent and optimum conditions were chosen and it has some guiding significance on practice . the main tasks include : by the contrastive experiments of sodium tripolyhosphate , sodium hexametaphosphate , na2edta and na4edta dissolving caso4 , na2edta and n ^ edta were chosen as cleaning agents in this experiment
主要包括：通过对三聚磷酸钠、六偏磷酸钠、乙二胺四乙酸二钠、乙二胺四乙酸四钠四种螯合剂对硫酸钙溶解性对比实验，最终选择乙二胺四乙酸二钠和乙二酸四乙酸四钠作为本实验清洗剂。 - Integrating the dissolving experiments of na2edta and na4edta and the orthogonal experiments , we can conclude that the dissolving property of na ^ edta is relatively more stable and higher than that of na2edta in this experiment . and , the conclusion can be made that for the caso4 scale in membrane na4edta has the best cleaning effect and the optimum condition is ph = 11 , operating pressure = 0 . 1mpa and concentration = 4 % wt
在综合考虑乙二胺四乙酸二钠和乙二胺四乙酸四钠对硫酸钙的溶解性实验及正交实验，和最后对污染膜清洗的正交实验可以看出，尽管最优工程选择中nazedta清洗后膜的相对恢复率略高于na4ed飞’ a ，但其要求条件相对苛刻，从溶解性实验也可看出， na4edrla对硫酸钙的溶解相对稳定，溶解率高。
