我国锑生产企业的环境保护,一直是一个比较棘手的问题。锑企业的环境污染,主要来自“三废”(废渣、废水、废气)的排放,其中炼锑低浓度二氧化硫烟气、砷碱渣和选矿废水,危害最大;其次为各种窑炉排放的烟尘、井下废石、各种工业废水、设备运转噪音等。自五十年代后期,湖南锡矿山即已开始“三废”的治理和综合利用的研究。近年来又成立了环境保护监测机构,对“三废”的治理进度较快,本文介绍有关治理的情况。
China’s antimony production enterprises environmental protection, has been a more difficult issue. Antimony enterprises environmental pollution, mainly from the “three wastes” (waste, waste water, waste gas) emissions, including low concentrations of antimony and sulfur dioxide flue gas, arsenic caustic soda and mineral processing waste water, the most harmful; followed by a variety of furnace emissions of soot, Downhole waste, a variety of industrial wastewater, equipment operation noise. Since the late 1950s, Hunan tin mines have started the research on the “three wastes” management and comprehensive utilization. In recent years, it has also set up an environmental monitoring agency to manage the “three wastes” progressively. This article introduces the relevant governance.
