试验用水主要污染因子:化学需氧量(COD)、氨氮(NH3-N)。
2.
Based on the analysis of variation of NH_3-N,phosphorus and organic compounds in soil samples from bottom mud and penetration media of river bed,it is found out that bottom mud has great effects on removal of NH_3-N and phosphorus,the amounts of which in mud are over ten times and one time as high as those in penetration media,respectively.
在凉水河下游取河床底泥及河床下部土样,分析其NH3-N、磷和有机物的变化,发现底泥对NH3-N和磷的去除发挥了很大作用,分别是下部土壤吸附量的10倍和1倍多;土中5种氯代烃均有检出,是河水长期渗漏积累的结果。

特性吸附与半胶束吸附
specifical adsorption and hemi-micelle adsorption
texing xifu yu banJ旧oshu xifu特性吸附与半胶束吸附(speeifieal adsorp-tion and hemi一mieelle adsorption)矿物一水界面的吸附的两种形式。特性吸附是因矿物表面与溶液中某种组分(离子或分子)有特殊的亲和力而产生的吸附，也称特殊吸附。特性吸附不仅可以改变电位的数量而且还可以改变电位的符号。例如，刚玉(A12O3)在NaZSO‘或RSO;Na(烷基硫酸钠)溶液中，电动电位随溶液浓度的增大由正值逐渐减小，直至变为负值，说明刚玉对50矛一或RSO不离子有特殊的吸引力。半胶束吸附是水溶液中的表面活性剂在矿物表面产生的吸附，当吸附量达到一定值以后，由于烃基的缔合作用，表面活性剂的离子或分子在矿物表面上形成紧密的吸附层，这类似于溶液中形成的胶束结构，但所形成的“胶束”与溶液中形成的胶束不同，只有二维空间，故称这类吸附为半胶束吸附。矿物表面对胺类捕收剂的吸附，当胺的浓度较大时，常可以产生半胶束吸附。 (龚焕高)
