摘　　要：调查了山西太原市集中供热循环水系统中主要造成管网腐蚀的有害微生物，包括粘液异养菌、 硫酸盐还原菌、铁细菌、真菌；测定了各菌群的数量分布、类型及与水温之间的关系。结果表明：在管 网供热期间，循环水中有害菌菌数普遍低于管网腐蚀的菌数指标；停止供热期间，循环水中菌数超 标，对管网造成一定的腐蚀。The microbial counts, type, as well as relationship between microbial counts and the temperature of water in reticulating water system of heating pipeline in Taiyuan were studied, which the main biofouling harmful microbes included slimeforming heterotrophic bacteria, sulfate reducing bacteria, iron bacteria and fungi, respectively. The results showed that the harmful microbes in water system were lower than that of control guideline during heating period, whereas the microbes were higher than that of control guideline, which would result in biofouling of water tube during non- heating period.
