摘要:
针对城市水体黑臭现象频发且治理困难的问题,利用接枝共聚法制备获得具有较高分子量和阳离子度的植物单宁絮凝剂(TGCC),以常州市北市河原位黑臭水样为对象,配合使用缓释气浮剂(CR-CP),开展生态絮凝-缓释气浮模拟实验,验证了改性植物单宁生态絮凝-缓释气浮技术的高效性及其应用于城市黑臭河道水质净化的可行性。从“外源污染控制”“水质提升修复”“长效稳定维护”“突发应急处理”4个方面提出了城市黑臭河道治理方案。
Abstract:
In response to the frequent occurrence and difficult treatment of black and odorous phenomena in urban water bodies, a plant tannin flocculant(TGCC) with high molecular weight and cationic degree was prepared by grafting copolymerization method. The black and odorous water sample from Beishi River in Changzhou City was taken as the object, and a slow-release air flotation agent(CR-CP) was used in combination to conduct ecological flocculation slow-release air flotation simulation experiments. The experiments verified the efficiency of modified plant tannin ecological flocculation slow-release air flotation technology and its feasibility in purifying water quality of urban black and odorous rivers. A treatment plan for urban black and odorous rivers has been proposed from four aspects: external pollution control, water quality improvement and restoration, long-term stable maintenance, and emergency response.
