排污单位自行监测检查中发现的典型问题及改进建议

Typical Issues Identified During the Examination of Self-Monitoring by Pollutant Discharging Entities and Suggestions for Improvement

排污单位自行监测的质量管理,是环境管理部门关注的重点。针对排污单位自行监测工作中存在的质控措施不规范;监测结果公开不完整;样品交接记录、原始采样记录、样品分析原始记录不齐全;流量计未检定或过期等问题。从自行监测方案的制定、自行监测信息公开、企业手工监测、企业自动监测等4个方面提出:应实施具体的质控措施;将污染物排放方式及排放去向、未开展自行监测的原因等方面的内容全部公开;通过计量认证第三方环境监测机构制订相关的记录单;将流量计送至计量单位实验室检定或者请计量单位现场检定等建议,对今后促进排污单位提高自行监测工作水平有指导意义。

The quality management of self-monitoring by pollutant discharging entities is an important focus of the environmental management departments.The existing problems in the self-monitoring work of pollutant discharge entities:irregular quality control measures;incomplete disclosure of monitoring results;incomplete sample transfer records,original sampling records,and sample analysis original records;flowmeters were not verified or expired.we provide detailed suggestions for improvement from four aspects:the formulation of the self-monitoring scheme,the disclosure of the self-monitoring information,the manual monitoring by enterprises,and the automatic monitoring by enterprises:Specific quality control measures should be implemented;all aspects of pollutant discharge methods and discharge destinations,and reasons for not conducting self-monitoring should be made in public;formulate relevant record sheets through third-party environmental monitoring agencies;Send the flowmeter to the measurement unit for laboratory verification or ask the measurement unit for on-site verification,etc.It is instructive to enhance the self-monitoring performance of the sewage disposal units.
