摘要

摘要: 针对污水处理厂污水处理构筑物藻类生长与黏附现象严重的问题，采用共混方法制备季铵盐（QAC）/环氧树脂复合涂层，并探究QAC投加量对复合涂层的性质和抑藻性能的影响。结果表明：QAC与环氧树脂涂料成功复合，改性涂层表面的季铵基团（R₄N⁺）数量随QAC投加量增大而增加；QAC改性对涂层的疏水性、耐水性不产生明显影响。但与环氧树脂涂层相比，随QAC浓度的增加，复合涂层表面的Zeta电位向正电性偏移，粗糙度略微减小；以小球藻（Chlorella vulgaris）作为模型藻类进行的涂层抑藻性能研究表明，QAC/环氧树脂复合涂层表面黏附的小球藻数目明显少于环氧树脂涂层，且QAC投加量越多，涂层抗藻污染性能越好。

Abstract: In municipal wastewater treatment plants, wastewater treatment facilities are usually covered by a great amount of algae. To solve this problem, in this study, quaternary ammonium compound (QAC)/epoxy composite coatings were prepared by blending QAC into epoxy paint. Effects of QAC dosage on the physicochemical properties and anti-algal adhesion/growth behaviors of the composite coatings were investigated. The results showed that QAC was successfully present on the modified coating and more quaternary ammonium groups (R₄N⁺) were loaded on the surface with the increase of QAC dosage. No significant differences in hydrophobicity and water stabilities were observed between epoxy coating and the modified ones. Compared to the original coating, zeta potential of composite coatings was shifted towards less negative potential and roughness was slightly lower as the result of QAC dosing. The inhibition properties of algae of the coatings were evaluated using Chlorella vulgaris as the model algae. Less Chlorella vulgaris were adhered on QAC/epoxy composite coatings than epoxy coating and better anti-algae performance was obtained with higher QAC concentration.
