摘　　要：根据天津市道路施工抑尘情况以及目前常用的抑尘措施的分析结果,本文尝试着以生物废弃物农用秸秆为原料制备出环保型抑尘剂,在模拟风蚀雨淋的情况下,其风蚀率为2.3%,雨淋损失率为3.1%,抑尘效果接近于市场购买的抑尘效果较好的化学抑尘剂A,但是环保型抑尘剂没有化学成分复杂、难以降解等弊端,具有环境友好性。此项研究不仅提高了生物废弃物利用率,而且有利于为后续天津市探索环保的道路施工抑尘方式提供思路。According to the dust suppression situation of road construction in Tianjin and the analysis results of common dust suppression measures at present,this paper attempts to prepare environmentally friendly dust suppressant using bio-waste agricultural straw as raw material.In the case of simulating wind erosion and rain,the wind erosion rate is 2.3%,the rain loss rate is 3.1%,and the dust suppression effect is close to the chemical dust suppressor purchased in the market.However,the environmentally friendly dust suppressant is not complex chemical composition and difficult degradation.This study not only improves the utilization rate of biological waste,but also provides a reference idea for the subsequent road construction in Tianjin to suppress dust.
