Technical specification for installation of wastewater
on-line monitoring system (CODCr, NH3-N et al.)
1 Scope of application
This Standard specifies the composition of wastewater on-line monitoring
system, construction requirements for wastewater discharge outlets, flow
monitoring units, monitoring stations, automatic water quality sampling units
and data control units, installation requirements for flow meter, automatic water
quality sampler and automatic water quality analyzer, as well as technical
requirements for debugging and trial operation of wastewater on-line monitoring
system.
This Standard is applicable to the construction of components of wastewater
on-line monitoring system (CODCr, NH3-N et al.), as well as the installation,
debugging and trial operation of wastewater on-line monitoring equipment such
as used flow meter, water quality automatic sampler, chemical oxygen demand
(CODCr) automatic water quality analyzer, total organic carbon (TOC) automatic
water quality analyzer, ammonia nitrogen (NH3-N) automatic water quality
analyzer, total phosphorus (TP) water quality automatic analysis Meter, total
nitrogen (TN) automatic water quality analyzer, thermometer, pH automatic
water quality analyzer.
The wastewater on-line monitoring system (CODCr, NH3-N et al.) standardized
in this Standard is applicable to the on-line monitoring of chemical oxygen
demand (CODCr), ammonia nitrogen (NH3-N), total phosphorus (TP), total
nitrogen (TN), pH, temperature and flow monitoring factors.
