Discharge of nitrate and ammonia rich wastewaters into the natural waters encourage eutrophication, and contribute to aquatic toxicity. Anaerobic ammonium oxidation process (ANAMMOX) is a novel biological nitrogen removal alternative to nitrification-denitrification, that removes ammonia using nitrite as the electron acceptor. The feasibility of enriching the ANAMMOX bacteria from the anaerobic digester sludge of a biomethanation plant treating vegetable waste and aerobic sludge from an activated sludge process treating domestic sewage is reported in this paper. ANAMMOX bacterial activity was monitored and established in terms of nitrogen transformations to ammonia, nitrite and nitrate along with formation of hydrazine and hydroxylamine.
富含硝酸盐和氨的废水排放到自然水中会促进富营养化，并导致水生毒性。厌氧氨氧化（ANAMMOX）是一种新型的生物脱氮替代硝化-反硝化过程，它利用亚硝酸盐作为电子受体去除氨。本文报道了从处理蔬菜废物的生物甲烷化厂的厌氧消化污泥和处理生活污水的活性污泥好氧污泥中富集厌氧氨氧化菌的可行性。通过监测氮的转化，包括氨、亚硝酸盐和硝酸盐的形成以及联氨和羟胺的形成，来确定厌氧氨氧化菌的活性。
