摘　　要：为进一步提高东营河口水厂高藻原水处理效果,为其升级改造提供技术支持,在沉淀池旁组建了中试装置,对不同滤料的试验滤柱进行了藻类总数和叶绿素a的去除对比试验。试验结果表明:煤砂双层滤料滤池能大大降低藻类总数和叶绿素a含量,且受藻类暴发的影响小,出水水质稳定;藻类大部分是在无烟煤滤料表层被吸附截留,很少出现穿透滤层及滤料黏附现象,可以有效缓解高藻水反冲洗次数多、难冲洗的问题。In order to further improve the treatment effect of high algae raw water in Dongying Hekou WTP and provide technical support for its upgrading a pilot plant next to the sedimentation tank was set up.The comparative experiment on the total number of algae and the removal of Chl-a was carried out on test filter columns with different filter materials.Test results showed that coal-sand dual media filter can not only greatly reduce the total number of algae and Chl-a,but also less affected by the outbreak of algae,and the effluent quality was stable.Most of the algae were adsorbed and trapped on the surface of anthracite filter material.Penetration of filter layer and filter material adhesion rarely occurs,it can effectively alleviate the problems of high algae water backwashing and washing difficulty.
