大型露天建筑绿色施工扬尘污染治理方法研究

Research on Dust Pollution Control Methods for Green Construction of Large Outdoor Buildings

扬尘对人体和周边环境都具有很大的危害。为实现绿色施工,进行扬尘污染治理是十分必要的,因此研究一种大型露天建筑绿色施工扬尘污染治理方法。该研究从白果中提取纤维素并制备成纳米纤维素,再制成纳米纤维素抑尘剂。将纳米纤维素抑尘剂喷洒到地面,固化后实现扬尘污染治理。根据是否喷洒抑尘剂,设置实验组和对照度,实施吸湿保水性能测试和风蚀性能测试,结果表明:实验组吸湿强度更高、保水率更大,土样质量损失率、TSP浓度更大,说明纳米纤维素抑尘剂喷洒能够保持土样湿润性,增强了土样的抗风蚀性能,起到了扬尘污染治理的效果。

Dust poses great harm to both the human body and the surrounding environment.It is necessary to carry out dust pollution control in order to achieve green construction.Therefore,it is necessary to study a method for controlling dust pollution in large-scale open-air green construction.In this study,cellulose was extracted from ginkgo and prepared into nanocellulose,which was then used to produce nanocellulose dust suppressants.Dust pollution control is achieved through spray the nanocellulose dust suppressant onto the ground and solidify it.Based on whether or not to spray dust suppressants,experimental groups and control groups were set up to conduct moisture absorption and water retention performance tests and wind erosion performance tests.The results showed that the experimental group had higher moisture absorption intensity,water retention rate,soil sample quality loss rate,and TSP concentration.This indicates that the spraying of nanocellulose dust suppressants can maintain the wetness of soil samples,enhance their wind erosion resistance,and achieve the effect of dust pollution control.
