Abstract: The invention provides a detection method of ammonia oxidation functional gene in water treatment, including the following steps. For a sample to be detected, ammonia oxidation functional genes are amplified by PCR, and primers used for PCR are modified by attaching biotin and digoxigenin to forward and reverse 5? ends respectively. Next, on the basis of immunochemistry, antibodies are used for biorecognition, and nano colloidal gold particles are used as chromogenic substances. The sample is placed on a sample pad of a lateral flow immunoassay test strip, and the sample flows from the sample pad to an absorbent pad. Color development on both the test and control lines when the sample flows through a nitrocellulose membrane indicates a positive result; color development solely on the control line indicates a negative result and no color development indicates an invalid test.
