Antimony.

As a flame retardant, antimony is part of many materials that find their way into waste incineration at the end of their life cycle. This report describes the sources and waste streams of antimony in waste incineration plants and identifies possible causes of increasing antimony loads. Part of the antimony passes into the flue gas during combustion and is transferred through the flue gas scrubber into the waste water, which is gradually purified. The scheme for water emissions under the Waste Water Emissions Ordinance for combustion gas currently provides for a limit value of 0.2 mg/l antimony. The suitability of different chemical-analytical examination methods to check this limit value was investigated in a laboratory comparison test.作为阻燃剂，锑（antimony）是众多材料的组成成分，这些材料在生命周期终结后会进入垃圾焚烧设施。本报告阐述了垃圾焚烧厂内锑的来源与废物流特征，并明确了锑负荷升高的潜在诱因。部分锑在燃烧过程中会进入烟气，并通过烟气洗涤装置转移至废水系统，随后废水将逐步得到净化处理。根据《废水排放条例》（Waste Water Emissions Ordinance）中针对燃烧烟气的水排放相关规定，当前锑的水排放限值为0.2 mg/l。本研究通过实验室对比试验，对不同化学分析检测方法在核查该排放限值方面的适用性进行了评估。
