摘  要：
根据抽样定律确定高碑店污水处理厂流域113家医疗机构中的北京医院等28家医院作为采样点,测定采样点排水中Hg浓度,计算Hg的总排放量,并分析了Hg排放量与医院床位数和门诊量的关系。结果表明,高碑店流域医疗机构Hg排放浓度较高,医院排水中Hg浓度(Y)与医院床位数(X1)和门诊量(X2)的关系式为:Y=3.11X1+0.098X2+166.94。流域内Hg排放总量为99.6g/d,根据高碑店污水处理厂的进水Hg浓度及日进水量计算出进水的总Hg量为828.0g/d,故高碑店流域内医疗系统对于高碑店污水处理厂进水Hg的贡献率为12.02%,说明流域内医疗系统对于高碑店污水处理厂进水Hg的贡献并不占主要地位。

摘  要：
Twenty-eight hospitals were selected from a total of 113(using standard sampling procedures)that contribute effluent to Gaobeidian sewage treatment plant in Beijing.The density and total amount of mercury(Hg)in the drainage systems of sampled hospitals were analyzed for Hg sources flowing into the Gaobeidian sewage treatment plant.Meanwhile released Hg amount by hospital,bed number and clinic number was analyzed and correlated.The results show high Hg densities in drainage systems from sampled hospitals.An empirical relationship exists between released Hg amount(Y)from hospital,bed number(X1),and clinic number(X2):Y=3.11X1+0.098X2+166.94.Total Hg amount released from the hospitals into the Gaobeidian sewage treatment plant area is 99.6g/d,and total Hg amount that enters into the Gaobeidian sewage treatment plant is 828.0g/d.Thus the addition percentage of Hg entering into the sewage treatment plant from hospitals is 12.02%,meaning that the hospitals are not major Hg source of the plant.
