通过硝化和反硝化的组合的微生物去除氮是废水处理过程中的众所周知的技术。污水处理厂中的硝化作用是一个敏感的微生物过程，会受到有毒物质的干扰。两个实验室的硝化抑制方法（ISO标准9509和呼吸抑制试验ISO 8192的修改）进行了研究与选定的物质，并与污水模型工厂的结果进行了比较。对于干扰的预测和预防，简单但可靠的实验室测试方法被证明是非常合适的。在实验室工厂进行的测试可以对硝化过程进行更全面的评价，并表明其对生物降解和适应过程的依赖。硝化作用的抑制取决于潜在抑制化合物的应用模式和生物降解性，生物降解性物质的抑制作用比难降解物质的抑制作用要轻得多。(c)2006爱思唯尔有限公司保留所有权利。
The microbial elimination of nitrogen by combined nitrification and denitrification is a well-known technology in wastewater treatment processes. Nitrification in wastewater treatment plants is a sensitive microbiological process, which can be disturbed by toxic substances. Two laboratory methods for nitrification inhibition (ISO standard 9509 and a modification of the respiration inhibition test ISO 8192) were investigated with selected substances and compared with results from sewage model plants. For the prediction and prevention of interferences, the simple but reliable laboratory test methods proved to be very suitable. The tests in laboratory plants allowed a much more comprehensive evaluation of nitrification processes and showed their dependence on biodegradation and adaptation processes. The inhibition of nitrification depended on the mode of application and the biodegradability of the potential inhibitory compound and was much less severe with biodegradable substances than with poorly degradable ones.
