荒煤气中苯并(a)芘(Bap)环境风险评价研究

对焦化过程中可能存在的环境风险因素进行了系统的识别与分析,并根据潜在的环境风险类型与危害程度,从中筛选出含有苯并芘的荒煤气一旦泄漏于环境中造成的后果影响进行了系统研究.研究结果表明:荒煤气的泄漏或者不采取任何措施直接释放于环境中,将对释放源周围环境造成较大不良影响.源强、不同区域的人口密度以及气象条件将是确定风险区域的重要因素.

Study on the environmental risk of Bap in the raw coal gas

It was identified and analyzed the potential environmental risk factors and was studied the consequences of leakage of the raw coal gas containing Bap systematically according to the types of the environmental risks and the harm extent in this paper.The results show that: if no measures were taken for the leakage of the raw coal gas and let it released directly,it would cause much adverse impacts on the surroundings.Risk-affected regions not only relate to the source of the gas leakage,but also to the weath...
