摘要

摘要: 在理论上改性黏土絮凝体的形态变化对其除藻过程有指示作用，可作为改性黏土用量和用法调控的依据，本文探讨了现有絮凝颗粒形态学观测与分析方法在改性黏土除藻效率评价上的适用性。借助激光颗粒表征技术和电子显微成像技术，本文观测了改性黏土除藻时的颗粒表面电性、粒径分布、絮凝体结构等絮凝形态学特征，分析了其与除藻效率的相关性。结果表明，现有观测方法可以表征改性导致的黏土颗粒Zeta电位反转、改性前后黏土在不同介质中的颗粒粒级分布差异、以及改性黏土与微藻形成絮凝体的多种显微结构；但由于较大粒径絮体对现有方法观测结果的影响更大，各种黏土的粒径特征与其除藻效率之间没有显著的相关性。现有观测方法获得的改性黏土颗粒形态特征仍不能反映其消除藻细胞的精细过程，特别是由于缺乏有效的絮凝体形态分析方法而导致现有形态参数还不能指示除藻效率的变化，亟需发展适用于改性黏土法除藻过程的颗粒形态分析新方法。

Abstract: The morphological attributes of aggregate particles formed by modified clays (MCs) with algae can theoretically guide the dosage and usage of the MCs in the red tide treatment. In this study, we discussed the feasibility of particle morphological measurement on evaluating the algal removal efficiency of MCs. We measured surface electricity, sizes and structures of the aggregate particles using laser technique and electron microscopy. Results showed that current methods reliably detect the reversion of clay particles surface electricity after being modified, the variation of particles grade when various clays were dispersed in different solvents, and the fine microscopic structures of aggregates formed between MCs and algae. However, the bigger particles which did not carry a corresponding ratio of cells to sediment had a great impact in system on the present morphological measurements. There were no significant correlations between the particle sizes and the algal removal efficiencies. Our observations suggest that the current methods were not sensitive enough to reveal the morphological variation of MCs particles and the present resolved characteristics could not denote the algal removal efficiency. Thus it's in urgent need of new methods to analyze the characteristics of aggregates formed by MCs and algal cells.
