| 通过对京杭运河苏州段经过的行政区的重点监控企业和污水处理厂的污染物排放情况统计分析，结果表明：754家重点监控企业涉及十多个行业，其中化学需氧量、氨氮、石油类、挥发酚排放量较高，分别为17 057 t、1 261.5 t、32.89 t、1.467 t。等标污染负荷比统计得出，吴江区、吴中区、高新区为重点监控区域，氨氮、化学需氧量、挥发酚、石油类为重点监控污染物，纺织印染、化工生产、电子产品信息制造、金属制造为重点监控行业。46家污水处理厂出口的化学需氧量、氨氮、总氮、总磷的年排放量分别为17 614 t、1 252 t、2 761.9 t、107.7 t,排放量较高且直接排入运河，也应将其划为重点监管区域。 |

| The discharge of pollutants from key monitoring enterprises and sewage treatment plants were analyzed statistically in surrounding area of Suzhou section of Beijing Hangzhou Canal. The results showed that，in 754 key monitoring companies involved in more than 10 industries，the emission amount of chemical oxygen demand，ammonia nitrogen，petroleum and volatile phenol were 17 057 t,1 261.5 t,32.89 t and 1.467 t，respectively. Statistics of equal standard pollution load ratio suggested that Wujiang district，Wuzhong district and Suzhou Xin district were the key monitoring areas，ammonia nitrogen，chemical oxygen demand，volatile phenol and petroleum were the main monitoring pollutants，while textile printing and dyeing industry，chemical industry，electronic product manufacturing and metal manufacturing industry were key monitoring industries. The emission amount of chemical oxygen demand，ammonia nitrogen，total nitrogen and total phosphorus from 46 sewage treatment plants were 17 614 t,1 252 t,2 761.9 t and 107.7 t，respectively. For the pollutants were discharged into the canal directly，the sewage treatment plants should be the key monitoring industries. |
