I. Implementation Standards:
《水质自动采样器技术要求及检测方法》 HJ / T372-2007 "Technical requirements and detection methods for automatic water sampler"
《水质样品的保存和管理技术》 HJ 493-2009 "Preservation and Management Technology of Water Quality Samples"
This product can realize the continuous collection and mixing of sewage at the discharge point, and use the mixed sample for the analysis of online analysis equipment to realize the monitoring function of the mixed sample of sewage at the discharge point. Solve the traditional online monitoring to monitor the sewage at the discharge point at equal intervals. However, the analysis period of water quality analysis instruments is often long, so the monitoring data obtained is only a set of sewage discharge data at equal intervals, which cannot truly reflect the problem of the total pollutant discharge at its discharge port. It can provide a powerful technical means for the total monitoring of sewage discharge and retention of samples exceeding the standard.
This product is mainly used in sewage discharge outlets of enterprises, and is used in conjunction with existing sewage online monitoring systems.
