摘要
本文以陕西丰富、低廉的风化煤为原料，活化处理制成腐植酸树脂。该树脂系天然高分子化合物，分子结构中含有大量的羚基、羟基、醌基等活性基团。利用它处理镀铬废水，吸附力强。交换性好、净化率高。且本身无毒，无二次污染。经静态和动态试验表明，交换容量大，使用寿命长。净化率远远超过国产S—006强酸型阳性树脂与Z7-15型柱状活性碳。
In this paper,the rich and low-priced weathered coal produced in ShaanXi can be taken as material, manufactured into humic acids resin, zhroush active phocess. Containing a large amount of active radical such ascaroxy group and hydroxy group, ect, in a structure of molymer, the resin is naturaland high holymer Compounds, The advantages of treating chnomicm -plating wastewater by using, it, are those of its strong absorbpower,excellent exchange and high cleaning power Without poison and twice pollution of ifself. There indicates Through both static and dynamic tests, a large exchange capacity and long service life for use. Its elimination rata o Cr^6＋ is such. that if far exceeds the pasive resin inn china-made S-006 strong acid type and column-shaped active carbon in a ZJ-15 type.
