The invention relates to the technical field of
water pollution control and treatment, in particular to a
nitrifying bacteria consortium, a preparation method thereof and application of the
nitrifying bacteria consortium in
wastewater treatment. The nitrobacteria consortia comprises
nitrosomonas sp. And
nitrobacter winogradsky, and a compact and spherical cenobium structure is formed; the
nitrification rate of the continuous passage of the nitrifying bacterium consortium is stabilized between 200-300mg NH4 < + >-N / L / h, so that the long-term stability of the nitrifying bacterium
community is ensured; meanwhile,
ammonia nitrogen can still be efficiently degraded under the extreme environmental conditions of high salt, high
alkalinity, high
aniline content and the like.
