摘要：研究了复合酶类生物激活物质对河道中微生物的作用机理,通过测定河道中微生物的生化呼吸线、细菌数、脱氢酶、纤维素酶、脲酶和磷酸酶的酶活性来表征生物激活物质对河道自净过程的促进作用.研究结果表明,复合酶污水净化剂对微生物活性具有激活作用,累积耗氧量明显增加,酶激活率达到14%～136%,有效增强了水体的自净能力.复合酶-原位生物修复技术在上海、北京和福州等多条受严重污染的富营养化河道的工程应用表明,复合酶污水净化剂在不同的地域条件下均可发挥良好的作用,具有安全、高效和适用性广等特点.
This paper focused on the research of effects＇ mechanisms of multiple enzymes on microorganisms in river. Biochemical respiration curve, number of microorganisms, enzymatic activities of dehydrogenase, cellulose, urease,phosphatase are identified to represent the functionality of multiple enzymes . These tests showed the effects of bioactivation substances on river＇s selfpurification process： multiple enzymes can stimulate microbe, especially increase the accumulated oxygen-consumption of microbe. Activation rate of enzymes ranges between 14% and 136%. As a result, the level of water body＇s selfpurification is improved distinctly. Meanwhile the applications of the in-situ bioremediation in Shanghai, Beijing, Fuzhou have proven that multiple enzymes have characteristic of safety, efficiency, applicability and can function well in different climes.
