纤维生物毯在城市面源污染控制中的应用

Application of fibrous biological blanket in control of urban non-point source pollution

城市地表硬化率过高导致面源污染加剧,影响地表水水质,纤维生物毯是解决城市面源污染的新技术,具有成本低、施工快捷、植物生长快、存活率高、景观效果好及管理方便等特点,可有效提高坡岸稳定性,具有良好的截留净化面源污染的能力。综述了纤维生物毯的结构功能、净化效果及影响净化效果的因素,指出了在提高坡面抗冲击性、增强土壤适应能力、改良材料与结构和降低维护成本等方面需改进的方向和方法。

The high rate of urban surface hardening can lead to increased non-point source pollution, and thus affect the water quality of surface water. The fibrous biological blanket is a new technology to solve the urban nonpoint source pollution. It has the characteristics of low cost, fast construction, fast plant growth, high plant survival rate, good landscape effect and convenient management. It can effectively improve the stability of the river slope and intercept and purify the non-point source pollution. The structure and function of fiber biological blanket,purification effect and factors of affecting the purification effect were summarized. The directions and methods to improve the impact resistance of slope surface, the adaptability of soil, the improvement of material and structure and the reduction of maintenance cost were pointed out.
