【摘要】 目的确定影响道路人工清扫过程扬尘大小的因素之间关系及排放因子量化模型。方法采用模拟实验方法,通过改变路面粉尘负荷q、清扫强度Q以及路面粉尘湿度F等条件,对影响道路清扫过程PM10发生的主要影响因素展开研究。结果提出了中国北方城市道路人工清扫过程扬尘中PM10浓度的量化计算模型。结论粉尘含湿量对道路人工清扫扬尘量的影响最大,粉尘负荷次之,清扫强度最小。更多还原

【Abstract】 Aim To analyze the relations of factors affecting the fugitive dust during road sweeping and bring up calculative models of discharging divisors.Methods By using simulated experimental methods and changing conditions of road surface dust loading q, sweeping intensity Q and road surface dust humidity F, studying the major factors affecting the PM₁₀ generation during road sweeping. Results The calculation models of PM₁₀ concentration of road sweeping are put forwavd in the northern cities of China.Conclusion The humidity of dust is the primary factor affecting fugitive dust about road sweeping, dust loading and cleaning intensity are subordinate factors.更多还原
