RESEARCH ON ENVIRONMENTAL POLLUTION CONTROL OF FUGITIVE DUST DURING CONSTRUCTION OF URBAN HIGH-RISE BUILDINGS

This paper mainly studies the index detection of dust environmental pollution during the construction of high-rise buildings and the standard value of the index detection in the process of urban largescale construction. We judge the damage to the natural environment and atmospheric environment according to the pollution of the dust environment during the construction of high-rise buildings and make reasonable adjustments and preventions according to the pollution control strategy of the dust environment during the construction of high-rise buildings and give experience in prevention and control of pollution. In order to effectively improve the current situation of the urban environment, the dust control and pollution emission response control of the construction of urban high-rise buildings have become the "main battlefield". The prevention and control work must be done well, and countermeasures must be given. Experiment 1 selects 8 basic points on the high-rise building construction site to set up detectors, builds a dust monitoring station to monitor and analyze real-time data, and samples the data within 24 hours for recording. Experiment 2 selects 8 basic points on the high-rise building construction site to set up detection. After adopting dust control measures, the instrument continues to collect realtime data at 8 points and records the data within 24 hours of sampling. Comparing the changes in the dust prevention and control data, the results of the analysis of the hazards of the dust on the environmental pollution are obtained, and the covariance line symbol model of Origin software is used to empirically analyze the changes in the trajectory of the environmental pollution degree before and after the dust prevention and control. By analyzing the detection data of 8 basic points and the data before and after the dust prevention and control, the average dust emission pollution is 180mg/m3, which exceeds the standard value. However, after adopting effective dust barriers, green plant protection nets, and micro can spray degradation prevention strategies, the average dust emission pollution is 15mg/m3, which meets the emission standards and is 220% lower than the standard value. The adoption of effective preven- tion and control measures and control strategies during the construction of urban high-rise construction sites can effectively prevent and control the pollution of the urban environment caused by construction dust, reduce pollution, and keep the urban air environment clean.
