摘要: 目前我国燃煤电厂脱硫废水标准DL/T997—2006的排放指标与限制内容已不符合社会发展需要,为此,本文提出了燃煤电厂脱硫废水排放指标限值相关计算方法。论文调研了美国和国内的相关规范,对排放指标确定范围的具体数值和算法模型展开深入研究,结合我国行业发展状况和国情给出了具体的修订建议,通过计算模型得出脱硫废水污染物控制参数的直接排放限值,氯化物日最大排放限值≤500mg/L,总溶解固体(TDS)日最大排放限值≤215mg/L,硒≤1.5mg/L,汞≤0.005mg/L等。

Abstract: The emission targets and limiting contents for coal-fired power plants including in the origin desulfurization waste-water standard (DL/T997-2006) are no longer in line with the social development needs in China, so the revised demand for new standard is proposed. In this paper, the relevant norms in the United States and China is investigated by the author, and concrete suggestions according to the revision need of the standard is given, including specific numerical and algorithmic models of emission target range. According to the development status of China's industry and the national conditions, specific revision suggestions are given. The direct emission limits of pollutant control parameters of desulfurization wastewater are obtained through calculation model, the maximum daily emission limit of chloride is ≤ 500mg/L, and the maximum emission limit of TDS is ≤ 215mg/L, selenium ≤ 1.5mg/L, mercury ≤ 0.005mg/L and so on. The research results have great significance for the determination of the limits of the emission index of desulfurization wastewater in coal-fired power plants in China.

Key words: desulfurization wastewater, standard revision, pollutant emission index, calculation model of concentration limit
