specific Embodiment approach

[0027] A specific embodiment of the present invention, an online bio-synergistic ammonia nitrogen removal method for sewage, comprising:

[0028] Analyze the water quality of the sewage to determine the water quality characteristic factors; prepare the best strains according to the water quality characteristic factors; activate and domesticate the configured best strains on site, and determine the proportion of wastewater; dynamically add on-site activation and domesticated strains.

[0029] Further, the water quality analysis is carried out on the sewage, the water quality characteristic factors are determined, and the best bacterial strains are prepared according to the water quality characteristic factors, including:

[0030] Carry out water quality analysis on at least one type of sewage, determine the water quality characteristic factors of the main pollutant types existing in the water quality, perform bacterial flora compounding according to the water quality characteri...

Abstract

The invention provides an on-line bioaugmentation ammonia nitrogen removal method for sewage, comprising the following steps: carrying out water quality analysis on sewage, determining the characterization factors of water quality; preparing optimal bacterial strains according to the characterization factors of water quality; activating and acclimating the prepared optimal bacterial strains on site, simultaneously determining the sewage proportion; and dynamically adding the bacterial strains activated and acclimated on site according to the water quality and water quantity of pretreated sewage. The on-line bioaugmentation ammonia nitrogen removal method solves the technical problem that ammonia nitrogen through industrial sewage treatment in the prior art is difficult to reach standards stably, can realize that ammonia nitrogen in sewage which can be biochemically treated can reach the standards and be discharged, reduces operating cost for enterprises, and simultaneously has better environment benefit.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an on-line biological synergistic ammonia nitrogen removal method for sewage. Background technique [0002] With the continuous improvement of environmental protection requirements, especially the increasing requirements of ammonia nitrogen discharge, it brings certain challenges to the treatment of nitrogenous wastewater. Efficient removal, especially the treatment of industrial sewage, it is more difficult to meet the ammonia nitrogen standard, so some bio-enhancement technologies and even online bio-enhancement technologies were born. This technology is mainly to add a certain amount of ammonia nitrogen to the treatment process of ammonia nitrogen wastewater. Nitrifying bacteria, so as to increase the concentration of nitrifying bacteria in its wastewater, but due to the adaptability of its strains and water quality, it is difficult for biosynergism to play a stable r...
