目前明矾仍为使用最广泛的混凝剂。六十年代日本首先使用羟基氯化铝作为净水剂我国在合成羟基氯化铝的基础上,又进行了提高混凝效果的研究工作。我们用优选法筛出SM-92号混凝剂的配方;以合理的工序制成了具有净水效果好、结絮快、颗粒大、澄清快的SM-92号混凝剂;并做了实验室及现场净水效果实验。 SM—92号混凝剂对饮水净化效果 (一) SM-92号混凝剂对各种不同水源净化混凝效果比较结果如表1.
Alum is still the most widely used coagulant. In the 1960s, Japan first used hydroxy aluminum chloride as a water purification agent. On the basis of the synthesis of aluminum hydroxychloride, it also carried out researches on improving the coagulation effect. We use the optimization method to screen out the formula of SM-92 coagulant; with a reasonable process has been made with a good water purification effect, fast flash, particle size, clear fast SM-92 coagulant; and experiments Room and site water purification effect experiment. SM-92 coagulant on drinking water purification effect (a) SM-92 coagulant on a variety of water purification coagulation results in Table 1.
