摘　　要：笔者采用浸渍提拉的方法将聚乙烯醇、硅溶胶、海藻酸钙等涂敷于多孔电气石板上对其进行改性,并通过SEM观察改性后对多孔电气石的生物相容性及其处理COD的能力进行测定。实验表明:聚乙烯醇和硅溶胶可以对多孔电气石进行改性,改性后多孔电气石板的生物相容性提高,微生物负载量增大。其处理COD的能力明显提高。负载PVA诱导膜的多孔电气石板的COD的最大去除率达到80%左右,负载硅溶胶诱导膜的多孔电气石板对污水COD的去除率达到79%。Porous tourmaline was modified by polyvinyl alcohol,silica sol and calcium alginate with dip-coating method.The biocompatibility of porous tourmaline was observed by scanning electron microscopy（SEM）and the ability of dealing with the COD was determined.Experiments show that：polyvinyl alcohol and silica solution on the porous tourmaline can be modified,modified to improve the biocompatibility of porous tourmaline plates,the load biomass increased.The removal rate of COD was significantly improved.The removal rate of COD of PVA-modified porous tourmaline improved to 80%than unmodified;silica sol-modified improved to 79%than unmodified.
