摘要
国内各煤炭港口粉尘排放量和上缴排污税没有统一计算标准。针对这一问题,通过分析影响煤炭起尘的关键因素,对国内外主要的起尘量计算公式进行了总结分析。在港口建设项目环境影响评价规范推荐公式的基础上明确公式量纲、修正风速参数、引入一次起尘事件源强概念、将翻车机作业纳入无组织排放的核算,最终构建了符合煤炭港口作业现状的排放总量计算公式。利用该公式对国家能源集团黄骅港粉尘排放进行测算,得出黄骅港清洁生产洒水作业与粉尘排放的对应关系。公式对政府部门核算各港口粉尘排放量、收取合理的排污税具有重要指导意义。
There is no unified calculation standard for dust emission and pollution tax paid in various domestic coal ports.In response to this problem,by analyzing the key factors affecting coal dust emission,this paper summarizes and analyzes the main calculation formulas for dust emission at home and abroad.Based on the recommended formula for the environmental impact assessment of port construction projects,the formula dimension is defined,the wind speed parameters are revised,the concept of source strength of a dust-raising event is introduced,and the operation of the dumper is included in the calculation of unorganized emissions.Finally the calculation formula of total emission which accords with the current situation of coal port operation is constructed.The formula is used to calculate the dust emission in Huanghua port of the national energy group,and the corresponding relationship between the water spraying operation and the dust emission is obtained.The formula has an important guiding significance for government departments to calculate the amount of dust emission from ports and to collect reasonable discharge tax.
