能源重工业区大气环境容量与大气环境整治研究

STUDY ON ATMOSPHERIC ENVIRONMENTAL CAPACITY AND ATMOSPHERIC ENVIRONMENTAL MANAGEMENT IN ENERGY HEAVY INDUSTRY AREA

利用不同风速出现频率条件下的箱式扩散模型对龙门能源重工业区的大气环境容量进行计算,SO2的环境容量为21097.72ta,TSP的环境容量为63293.15ta。运用资料收集法和成果参照法分别统计有组织排放的污染物量和计算无组织排放的污染物量,SO2为13728.79ta,TSP为68555.97ta。小风及静风条件下SO2的大气环境容量利用率为71.2%,TSP的大气环境容量利用率为108.1%;大风条件下SO2的大气环境容量利用率为30.1%,TSP的大气环境容量利用率为109.6%。研究结果表明,在不同的风速条件下,污染情况有所不同。SO2主要是有组织排放,其容量相对剩余量为7368.93ta。TSP已经超容量,大风条件下,煤堆起尘、裸露地面扬尘是主要的污染源;小风条件下,大气污染由无组织扬尘和有组织排放共同作用。针对园区存在的环境问题,提出相应的大气环境整治措施。

The atmospheric environmental capacity in Longmen Energy Heavy Industry Area is calculated using a box model of different frequency of wind speed.The result shows that the capacity of sulfur dioxide and TSP is respectively 21 097.72 t and 63 293.15 t in a year.The method of selecting data and benefit transfer approach are respectively put into use to add up systematically discharging capacity and calculate the unsystematically discharging amounts,and the amount of sulfur dioxide is 13 728.79 t/a,and TSP is 68 555.97 t/a.The using ratio of SO_2 of atmospheric environmental capacity is 71.2%, and TSP is 108.1% on small wide speed and still wind occasion.The using ratio of SO_2 of atmospheric environmental capacity is 30.1%,and TSP is 109.6% on gale occasion.The result shows air pollution is different in different conditions, that is to say, SO_2 comes from systematically discharging, comparative spare capacity is 7 368.93 t/a.And TSP is in excess of its capacity, flying dust about coal and uncovered floor are main pollution sources on gale occasion,and atmospheric pollution is produced by systematical discharging and unsystmatically flying dust.At last, the measures of integrated control of air pollution is put forward which aimed at environmental problems.
