| 中文摘要: |
| 恶臭污染是化工园区环境污染的重点类型之一,恶臭异味投诉一直是困扰南京化学工业园区的热点问题。2021年,南京市政府为全力解决该园区异味投诉问题,开展了为期1年的现场嗅辨、VOCs现场采样-仪器分析、走航监测等多手段跟踪溯源监测,对筛查出的重点企业和工序进行目标靶向治理,通过采取增加污染治理设施、限时限量生产、加强现场执法监管、加强测管协同监测等手段进行综合协调管控。通过对南京化学工业园2021年5月14日至2022年4月30日现场嗅辨、VOCs现场采样-仪器分析、走航监测以及园区环境空气质量自动监测站点监测结果进行统计分析发现:企业污染物排放异常情况虽偶有波动,但明显减少;园区硫化氢和VOCs特征污染物自动监测浓度明显降低,环境空气质量改善明显;周边居民投诉量从2021年1—5月的60多次降低到6—12月的20次,下降明显。多种方式监测结果变化情况反映出省、市、区采取的各类园区恶臭异味管控措施取得了显著成效。 |

| Odor pollution is one of the key types of environmental pollution in chemical industrial parks,and odor complaints have always been a hot issue that troubles Nanjing Chemical Industrial Park.In 2021,the Nanjing Municipal Government launched a comprehensive one-year monitoring campaign to trace odor sources,employing multiple approaches including on-site sniffing,VOCs on-site sampling with instrumental analysis,and navigation monitoring.Targeted governance was carried out on identified key enterprises and processes,and comprehensive coordination and control were carried out through measures such as increasing pollution control facilities,imposing time-restricted and quantity-limited production,strengthening on-site law enforcement supervision,and strengthening collaborative monitoring of measurement and management.Based on the statistical analysis of monitoring data including on-site olfaction,VOCs sampling with instrumental analysis,navigation monitoring,and automated ambient air quality stations in Nanjing Chemical Industry Park from May 14,2021 to April 30,2022,it was found that although the abnormal emission of pollutants by enterprises fluctuated occasionally,it decreased significantly.The concentrations of characteristic pollutants for automatic monitoring of hydrogen sulfide and VOCs in the park significantly decreased,and the environmental air quality improved significantly.The number of complaints from surrounding residents decreased significantly from over 60 from January to May 2021 to 20 from June to December.The changes in monitoring results through various methods reflect that the various measures taken by province,city,and district to control odors and unpleasant odors in industrial parks have achieved significant results. |
