摘要
利用水生植物修复污染水体具有成本低、能耗小、治理效果较好、经济效益较好和有利于整体生态环境改善等优点,是水环境修复的一个良好方法。一种新型的去污材料——人工净水草,由于生物膜生成、固着性能良好,废水与生物膜接触效率高,不造成二次污染,可快速脱氮、抑制藻类生长、提高水体透明度,因此可在低温季节与水生植物组合,以达到较好的污水净化效果。
Phytoremediation is a good method of sewage treatment, which has less investment, lower energy consumption, better treatment effect, better economic benefits and in favor of the overall ecological environment. Meanwhile, in order to achieve a better sewage purification effect, a new kind of decontamination materials, N - grass could be combined with aquatic plants in low temperature, not only because of its good biofilm formation and solid performance, but also the high efficiency mating face contacting with waste water and biological membrane, which can avoid causing secondary pollution, rapid denitrifieation, inhibit the growth of algal and imorove the transparency of water.
