Foreword

This standard proposed by the Ministry of Housing and Urban Standard and Design Institute.

This standard by the Ministry of Housing and Urban Water Supply and Drainage Products Standardization Technical Committee.

1 Scope

This standard specifies the town sewers flammable gas, hydrogen sulfide, oxygen, ammonia, carbon monoxide, sulfur dioxide, chlorine, dioxide Laboratory testing of carbon and total volatile organic gases and/or rapid on-site testing methods.

This standard applies to urban areas to accept and transport urban sewage, industrial wastewater and rainwater pipe network, ditches and pumping stations, sewage treatment facilities, sludge Determination of accumulated gas in final disposal facilities and other related facilities.

3 Terms and definitions

The following terms and definitions apply to this standard.

Drainage in the pipeline, structures and equipment collectively.

Refers to the common structures in the drainage of flammable and explosive and toxic and harmful gases, namely flammable gas, hydrogen sulfide, oxygen, ammonia, monoxide Carbon, sulfur dioxide, chlorine, carbon dioxide and total volatile organic compounds.

Refers to the temperature of 273K, the pressure of 101.325kPa dry matter state.

TenaxGC or TenaxTA samples were run on a non-polar column (polarity index less than 10) for analysis with retention times in n-hexane and n-hexadecane volatile organic compounds.
