摘要
介绍了近年来用于絮凝法处理含汞废水的7种新型螯合絮凝剂(聚硅酸锌、三聚硫氰酸三钠、2-巯基乙胺接枝聚丙烯酰胺、双硫腙接枝聚氨酯、PS-DCDA、聚乙烯亚胺基黄原酸钠及水合肼改性果胶)的性能和絮凝效果。指出新型、高效、无害化螯合絮凝剂的研发对氯乙烯合成含汞废水的无害化处理具有重大意义。
The properties and flocculation effect of seven kinds of new chelating flocculant, i. e. polysilicate zinc, trithiocyanuric acid trisodium salt, 2-mercaptoethylamine grafted polyacrylamide, dithi- zone grafted polyurethane, PS-DCDA, polyethyleneimine-sodium xanthogenate and hydrazine hydrate modified pectin, for the treatment of mercury-containing wastewater in recent years were introduced. It was indicated that the development of new, high efficiency and harmless chelating flocculants were of great significance for the harmless treatment of mercury-containing wastewater.
