The screening of efficiently Nitrifying bacteria in the comprehensive utilization of urban water
Abstract: Now the serious problems of water. The urban water utilization of water resources is the effective way to relieve the tension. Ammonia nitrogen is one of the main problems who block water recycling. Therefore, how to urban sewage treatment plants will water depth denitrification become the research focus This article introduced the screening domestication and purification of the Nitrifying bacteria from ximi lake. There are two strains isolated from experiment By degrees spectrophotometry samples of ammonia nitrogen and N - (1 - naphthalene) - ethylenediamine spectrophotometric determination and concentration of nitrogen nitro identifying its nitrification ability. And the temperature of the influence of nitration rate, the results indicate that the temperature of 25-30 ° c, the maximum rate of nitration.
