摘　　要：在很多工业废水处理过程中,都会有泡沫出现。有了泡沫,就会减少处理能力和降低处理速度,并极大地增加处理厂家的整体运行费用。具体来说,与起泡有关的问题可使厂家每年因损失生产能力和增加保养费用而浪费成千上万美元,且不提由泡沫溢出和清除它们所带来的麻烦。环境工程师们需了解可以减少或根绝泡沫的各种有效方法,以最大限度地提高产出、减少生产和保养费用,并创造一个安全的工作环境。During many industrial wastewater treatment processes, various forms of agitation cause foam to occur. The presence of foam reduces capacity and processing rates, dramatically increasing a plant's overall operating costs. The industrial wastewater industry has typically used two methods to control foam: mechanical knockdown systems and foam control agents, or antifoams. Antifoams for wastewater treatment generally fall into one of two categories: Organic and silicone. Silicone antifoams are considered by users and researchers to be more effective foam control agents. Their highly—efficient, long—lasting action, inert properties and defined toxicological status make silicones a perfect match for waste treatment operations.
