一种长效抑藻仿生水草

Abstract

本实用新型涉及一种长效抑藻仿生水草，浮体外围包裹无纺布，浮体下方固定配重体，无纺布外围固定季铵盐壳聚糖改性绳状人工水草，浮体周边装至少一个微生物降解型缓释抑藻模块。有益效果为：在暴藻期投入长效抑藻仿生水草，最外层的季铵盐壳聚糖改性绳状人工水草迅速启动反应，短期内快速抑藻，待绳状人工水草上支接改性的季铵盐壳聚糖消耗完后，其主要作用为生物载体，定向富集微生物，为微生物降解型缓释抑藻模块启动奠定基础，也可以有效削减水域污染物，提高对水体污染物去除率，随着微生物降解型缓释抑藻模块被微生物降解，被裹挟的抑藻物质逐步释放，继续抑制未被杀死的藻类及沉在底部的藻孢子，从而实现长效抑藻，且不反弹。
