为开发安全、高效、廉价的水华控制技术,选择铝土矿、磷铁矿、黄铁矿、铬铁矿及橄榄石等10种天然矿物材料,以水体铜绿微囊藻为研究对象,通过跟踪测定其叶绿素a的变化,研究了天然矿物对水体铜绿微囊藻去除特性,并探讨了天然橄榄石去除铜绿微囊藻的影响因素及去除机理。结果表明:相同条件下天然橄榄石具有最高的除藻能力;矿物用量及藻密度对橄榄石除藻过程影响最大,其次为pH及水温,光强影响最小;当橄榄石浓度为1.5 g·L
、水温15 ℃、反应介质为弱酸性或中性(pH 5~7)时,吸附1 h后,叶绿素a去除率高于96%。进一步分析可知,天然橄榄石主要通过静电作用对铜绿微囊藻进行吸附,进而使藻细胞絮凝沉降,部分藻细胞破裂分解,同时天然橄榄石在反应过程中吸附培养基中的营养盐,造成藻细胞营养缺少,从而对藻细胞的生长造成一定的抑制作用。
In order to develop a safe, efficient and inexpensive water bloom control technology, ten kinds of natural minerals such as bauxite, phosphorite, pyrite, chromite and olivine etc. were evaluated by their
removal charactrsitics in terms of the variations of chlorophyll a content. Moreover, the influence factors and mechanisms of
removal by olivine were studied. The results showed that natural olivine had the best performance under the same conditions among the tested natural minerals. The olivine dosage and algae density presented the greatest effects on algae removal, followed by pH and water temperature, while light intensity showed the least effect. More than 96% of chlorophyll a was removed after 1 hour adsorption by olivine at olivine dosage of 1.5 g·L
, water temperature of 15 ℃, and weak acidic or neutral (pH 5~7) reaction medium. Further analysis indicated that electrostatic interaction palyed a main role on
adsorption by natural olivine, then the coagulation and sedimentation of algae cells occurred, and some algae cells broke down. At the same time, olivine could absorb the nutrients in the medium during the reaction process, and reduced the nutrients for algae cells, thus inhibited algae cells growth to some extent.
