染料涂料废物贮存豁免量限值研究

Exemption Limit Value for Waste Dyes and Paints Storage

针对染料涂料废物管理的贮存环节,基于地下水迁移扩散和大气扩散的暴露场景,通过环境风险评价,制定漆渣、废水处理污泥、废油墨油漆的贮存豁免量限值。结果表明,固态废物(污泥和漆渣)的贮存豁免量极小,没有豁免管理意义。在桶装(无盖)、开放或半封闭堆场、地面有硬化和防渗系统场景下,废油墨油漆的贮存豁免量限值为262kg/a。

The storage process of waste dyes and paints was focused on. Based on the groundwater transport and diffusion scenario and air diffusion scenario, the exemption limit values （ELVs） for the storage of paint slag, wastewater sludge, and waste ink and paint was figured out using environmental risk assessment methodology. The resuhs showed that the exemption limit value of solid phase waste （paint slag and wastewater sludge） storage was too little for exemption management. For waste ink and paint storage, the exemption limit value was 262 kg/a under bucket package without cover, open or semi-closed storage yard, harden ground and anti-seepage scenario.
