HJ 353-2019 (English Version) PDF

Scope: This standard specifies the components of an online monitoring system for water pollution sources, construction requirements for water pollution source discharge outlets, flow monitoring units, monitoring stations, automatic water quality sampling units and data control units, flow meters, automatic water quality samplers and automatic water quality analyzers. The installation requirements, as well as the technical requirements for debugging and trial operation of the water pollution source online monitoring system. This standard applies to the construction of all components of the online monitoring system for water pollution sources, as well as the flowmeters, automatic water quality samplers, automatic chemical oxygen demand (CODcr) water quality analyzers, and total organic carbon (TOC) automatic water quality analyzers used. Installation, commissioning and trial operation of online monitoring instruments for water pollution sources such as ammonia nitrogen (NH3-N) water quality automatic STAN. The online monitoring system for water pollution sources specified in this standard is suitable for online monitoring of chemical oxygen demand (CODcr), nitrogen (NHs-N), BFCTP), total nitrogen
