国控重点污染源监督性监测质控抽测工作的思考

Discussion on Spot Checking Quality Control of Supervision-monitoring for the State Controlling Key Point Pollution Sources

简述了开展国控重点污染源监督性监测质控抽测的内容。指出,目前国控重点污染源监督性监测中尚存在的问题,部分采样平台和监测断面设置不符合技术规范,监测仪器与监测方法不统一,监测数据的可比性不强,监测能力建设没有完全到位,现场仪器使用导致监测结果偏差。提出,加强手工监测全过程质控工作,配备精度较高的污染源现场监测仪器,加强污染源现场监测技术和仪器设备技术标准的研究,加强企业排污口规范化建设,加强污染源监测数据可信度评分办法等的研究,进一步推动污染源监测工作,使得污染源监测数据更好地反映污染源排放的实际情况,为管理部门提供准确的监测数据。

The spot checking quality control of supervision-monitoring for the state controlling key point pollution sources were introduced. It revealed the existence of problems such as inconsistence with the technical specification for some settings of sample platform and monitoring section, poor fit of monitoring instruments and monitoring method, uncomparable monitoring data, inadequate construction of monitoring capability and the inaccurate field uses of instruments leading to incorrect monitoring result. It proposed measures including strengthening the control quality of manual monitoring during the whole process, providing field instruments with higher precision at the pollution sources, strengthening the search of monitoring technology for pollution sources and the technical standard of the instruments, strengthening the standardization construction of pollutants discharging outlet in enterprises, strengthening the search of credibility grading method of monitoring data from pollution sources. Generally, it needs further improvement of pollution source monitoring to reflect the real discharge level at the pollution sources, so as to provide accurate monitoring data for the administration sections.
