关于修订《贵州省环境污染物排放标准》的思考——以水污染物排放标准修订为例

Comments on revision of Emission Standards for Environment Pollutants in Guizhou Province( DB 52 /12- 1999) : taking water pollutant emission standards as an example

DB 52/12—1999《贵州省环境污染物排放标准》自第一次修订至今已有13年,随着我省经济社会的发展,现行标准执行过程中暴露出一些不足之处,导致标准执行困难。针对现行标准中存在的问题,在对有关法律法规、本省主要工业结构、特征污染物和国外相关排放标准进行研究分析的基础上,以水污染物为例,对标准制定中有关排放等级、时段划分、污染物控制限值等内容进行了思考。

Emission Standards for Environment Pollutants in Guizhou Province （DB 52/12 - 1999 ） has been in use since its first release in 1999 and the update to it is necessary. Referring to relevant state law, regulations and foreign emission standard, in addition the analysis of the characters of local industries and their major water pollutants, this paper recalculated maximum acceptable concentra- tion, and presented more reasonable phase - out period and emission grade division for amendment of the emission standard.
