Experiments are conducted on the effect of different types and different molecular structures of polymers on HPAM removal existed in solution or sewage. It is found out that only cationic polymer has a better removal effect of HPAM among the non-ion, amphoteric ion and hydrophobical cation polymers, especially the DMDAAC cationic polymer has an optimal result. The removal capacity to HPAM can be further improved by using appropriate molecular weight and cationic capacity and gas floatation technique.
试验研究了不同类别及分子结构的聚合物对溶液或污水中HPAM的去除效果,发现非离子、两性离子、疏水改性阳离子聚合物对HPAM无去除作用,只有阳离子聚合物去除效果较好,其中尤以DMDAAC系列阳离子聚合物效果最优,而适当的分子量和阳离子化度以及气浮技术均可以进一步提高其对HPAM的去除率。

The new opinion and mechanism that the simultaneously adsorption of complex pollution of both organic and heavy metals will be achieved on soil modified with amphoteric surface modifying agent, which have both charged group and organophilic group on one ASMA molecule, were proposed at first time, and its rationality was testified at the same time; The 50% was the critical CTMAB modifying ratio of soil CEC at which the organophilic bond modifying mechanism was emerged; The thermodynamic characteristics of adsorption of OPT and HMP on OMS were discovered ; The study revealed the surface peculiarity of OMS that the modifying agent were distributed at uneven scatter mode and multi-characters surface were coexisted on surface of OMS, revealed the adsorption peculiarity of OMS that multi-mechanisms were coexisted, confirmed the unequal charge amount modifying mode of OMS in which dual-modifying mechanism of both ion exchange and OPB were processed at the same time, and confirmed that the adsorption hobby to CTMAB was higher than that to Ca2+ on Lou soil.
首次提出了用两性表面修饰剂对土壤进行修饰改性,利用两性表面修饰剂所具有的荷电基团和疏水基团达到对土壤中有机、重金属污染物同时吸附的思路和机理,并通过实验证实了所提设想的合理性;发现了土壤CEC值的50%修饰比例是CTMAB开始显现以疏水键机制对土土样表面进行修饰的临界点;揭示了有机修饰改性土对有机物、重金属吸附过程的热力学特征,填补了该项研究工作的空白;阐明了修饰剂在改性土表面呈分散态的非均匀分布,改性土表面具有不同性质表面共存的表面特征和对污染物多机制共存的吸附特征,确定了阳离子表面修饰剂在土表面的修饰是一种离子交换和疏水键结合两种机制相伴并行且为非等电荷量交换的修饰反应模式,以及土具有对CTMAB的吸附偏好性远大于对钙离子吸附偏好性的特征。
