Research On Dust Pollution Control In Building Construction

With the further advancement of urbanization in China,the urban air environment has received more extensive attention.Haze and haze has begun to jeopardize the health of the public and has become a hot topic of public discussion.To realize source control and effectively control atmospheric particulate matter is an urgent problem to be solved at this stage.Construction production activities are the main source of dust,and open-air construction activities will discharge dust particles into the atmosphere.This article takes this as an entry point to monitor the dust emission of each construction stage,apply environmental-friendly dust suppression agents to the construction site,and monitor the changes in dust concentration data,combining construction phase characteristics,and put forward comprehensive plans for construction dust control,and propose construction The effective control of dust pollution has actually improved the quality of the atmospheric environment.First of all,this paper has classified and summarized the monitoring status and governance status of atmospheric particulates at home and abroad,extracted the commonalities and summarized them.Based on this,it put forward the implementation plan and technical route for dust control in this paper,and adopted quantitative monitoring methods to dust the construction.A scientific and intuitive assessment of quantity.Secondly,field surveys and pre-monitoring methods were used to compare and sum up the size of dust emission in each construction phase and in different construction phases.It was clarified that in the three phases of earthwork,main structure,and interior construction,the construction of key treatment in this study was conducted.activity.Based on this,the types of environmentally-friendly dust suppressants were determined to be non-toxic,harmless,and degradable alginate dust suppressants,and five typical projects under construction such as Fengqitai were selected to carry out non-treatment,watering,and seaweeds respectively.Sodium dust suppression agent three kinds of dust suppression application.The dust suppression agent was applied to the key dust-producing areas during the construction phase as the test group;the same area was selected as the control group for watering and dust suppression,and the TSP concentration was monitored at the same time to observe the dust suppression status of the dust suppression agent.Summarize the characteristics of different states and describe them.Finally,comparing the effect of dust suppression agent with watering and non-treatment dust suppression,the effective duration of this type of dust suppression measures was analyzed,and comprehensive consideration was given to factors such as background concentration of dust,average value of TSP concentration,and dust suppression efficiency.Specific and reasonable measures are recommended.The research in this paper provides a novel idea for the dust control of building construction,that is,the application of environmentally friendly dust suppression agents,the overall research process has a scientific basis,and finally puts forward effective measures for dust control,which is suitable for promotion and application in construction sites in China.Effectively solve the problem of dust pollution on the construction site,reduce environmental pollution,and achieve green construction.
