摘要
以长三角地区制药企业为研究对象,采用AERMOD模型、一维非饱和溶质运移模型模拟研究了大气沉降、污水垂直入渗对土壤环境质量的影响,研究结果表明:1)在达标排放的情况下,大气沉降对土壤影响较小,其中三氯甲烷年贡献占标率为 0.057%;2)污水垂直入渗会造成一定的土壤环境污染.企业应进行土壤环境隐患排查,并落实相应土壤环境保护义务.
Abstract
Taking pharmaceutical enterprises in Yangtze River Delta as the research object,AERMOD model and one-dimensional unsaturated solute transport model were used to simulate the effects of atmospheric subsidence and vertical sewage infiltration on soil environmental quality.The results showed that:1)under the condition of standard discharge,atmospheric subsidence had little impact on soil,in which the annual contribution rate of trichloromethane was the largest,accounting for 0.057%.2)Vertical infiltration of sewage will cause certain soil environmental pollution.Enterprises should conduct soil environmental hazard investigation and implement corresponding soil environmental protection obligations.
