Область применения

This standard applies to all units across China that discharge odor pollutants into the atmosphere, as well as garbage dumping sites. It governs emission management, environmental impact assessments, design, and竣工验收 for construction projects. It is mandatory for facilities with both organized emission sources (exhaust stacks) and unorganized emission sources. The standard specifically targets eight regulated odor pollutants and composite odor concentrations.

Технические требования

GB 14554-93 establishes maximum emission limits for eight specific odor pollutants, including ammonia, hydrogen sulfide, and styrene, along with composite odor concentration limits. The standard divides factory boundary limits into three tiers based on the ambient air quality zones defined in GB 3095. For organized emissions, the standard specifies emission rate limits (kg/h) that vary according to the exhaust stack height. Facilities must ensure that both the discharge volume and odor concentration from stacks equal or below 15m comply with the unorganized source boundary limits. The standard also differentiates requirements between new, expanded, or modified construction projects and existing facilities, with stricter limits generally applied to new projects. It explicitly states that no new emission units are permitted in Class I protected zones.

Методы испытаний

The standard outlines specific sampling and analytical methods for both organized and unorganized emission sources. Sampling frequencies are determined by production cycles, with strict guidelines on monitoring points at factory boundaries (downwind). Testing methods rely heavily on gas chromatography and spectrophotometry as defined in referenced standards such as GB/T 14675 for odor concentration (triangle odor bag method) and GB/T 14678 for sulfur compounds.

Частые вопросы

What specific odor pollutants are regulated under GB 14554-93?

This standard regulates eight specific odor pollutants: ammonia, trimethylamine, hydrogen sulfide, methyl mercaptan, dimethyl sulfide, dimethyl disulfide, carbon disulfide, and styrene, along with composite odor concentration.

How does GB 14554-93 classify emission standard limits?

The standard classifies limits into three tiers based on the ambient air quality zones defined in GB 3095. Facilities must comply with the tier corresponding to their geographical location, with no new emission sources allowed in Tier 1 zones.

Are there different requirements for new versus existing facilities under GB 14554-93?

Yes, it distinguishes between new, expanded, or modified facilities and existing facilities, generally imposing stricter limits on new projects. It also sets specific exhaust stack height requirements (minimum 15m) and corresponding emission rates for organized emissions.
