HJ/T 397-2007Technical specifications for emission monitoring of stationary source (English PDF)

Foreword

This Standard is established to carry out the Environmental Protection Law of the People's Republic of

China, and Law of the People's Republic of China on the Prevention and Control of Atmospheric

Pollution, prevent and control atmospheric pollution, and improve environmental quality.

This Standard specifies the manual sampling and determination of particulate and gaseous pollutants

monitoring methods in smoke flue, chimney, vent emission funnel and other fixed pollutant sources; and

the monitoring methods of the portable instruments. It formulated corresponding provisions on the

preparation for emission monitoring of stationary source, determination of exhaust emission parameter,

sampling and determination method of particulates and gaseous pollutant in exhaust, and the quality

assurance of monitoring, etc.

Annex A of this Standard is Informative Annex.

This Standard is first-time released.

This Standard was proposed by the scientific and technical standard department of State Environmental

Protection Administration.

This Standard was mainly drafted by organizations. China National Environmental Monitoring Center,

and Shenyang Municipal Environmental Monitoring Center.

This Standard was approved by State Environmental Protection Administration on December 7, 2007.

This Standard shall be Implemented from March 1, 2008.

This Standard shall be interpreted by State Environmental Protection Administration.

Technical specifications for emission monitoring of

stationary source

1 Scope

This Standard specifies the manual sampling and determination of particulate and gaseous pollutants

monitoring methods in smoke flue, chimney, vent emission funnel and other fixed pollutant sources; and

monitoring methods of the portable instruments. It formulated corresponding provisions on the

preparation for emission monitoring of stationary source, determination of exhaust emission parameter,

sampling and determination method of particulates and gaseous pollutant in exhaust, and the quality

assurance of monitoring etc.

This Standard applies to the environmental monitor stations at all levels, industry and enterprise

professional organizations, and environmental scientific research institutes, to carry out the emission

monitoring of exhaust pollutants of stationary source; environmental protection acceptance monitoring

upon the completion of construction project; monitoring on the control effect of pollution treatment

facilities; verification monitoring on continuous emission monitoring system; and the technical research

monitoring of clean production process and pollution prevention.

4 Preparations for testing

Formulation of monitoring scheme

4.1.1 Collect related technical data, and understand the technological process of production and the

performance of production facilities that generated exhaust gas, the category of the principal pollutant

emitted and the general scope of emission concentration, to determine the monitoring items and

monitoring methods.

4.1.2 Survey purification principle, process engineering, major technical indicators and others of process

engineering facilities of pollution source to determine the monitoring content.

4.1.3 Survey operational condition of production facilities, emissions methods and rules of pollutants to

current is in direct proportion to the mole number of the oxygen atom involved in the reaction, the current

generated from discharging is transferred into voltage via load, and the volume fraction of oxygen can be

obtained by measuring the voltage on the load.

b) Instruments.

1) Oxygen meter, consisted of air pump, flow control devices, control circuit and display screen.

2) Sampling pipe and the sample gas preprocessor.

c) Determination steps. Connect the gas circuit according to the requirements of instrument's instruction

manual, and perform leak test on the gas circuit system; start the instrument air pump; after the

self-inspection of instrument is finished and indicates that it operates normally, insert the sampling pipe

into the center or position nearby of the tested flue to sample flue gas for determination, and read the

data when the reading of oxygen content is stable.
