First, the circulating water why brushing anti-fouling I plant the existing three circulating water (80) were put into operation in 1969, 1971, 1976. Before due to lack of understanding of water quality, to take effective measures to a small extent, resulting in part of the heat exchanger fouling and corrosion, especially after the sewage reuse did not take sterilization algae removal measures, resulting in a large number of microbial growth and reproduction. Ketone benzene dewaxing device cold -509 in February 1974 due to blockage with sulfuric acid cleaning invalid, the head cover apart, see the tube bundle with a small amount of suspended solids and leaves, most of the 2 to 3 mm thick dirt, Through microscopic examination, found that most of the algae, microorganisms, bacteria, such as body cadaver
