1, increase the anoxic section in the biochemical tank, which can promote the role of denitrifying bacteria, reduce nitrate nitrogen to nitrogen, thus reducing the total nitrogen content.
2, increase denitrifying bacteria in the biochemical tank, can earn denitrification, further reduce the total nitrogen content.
3, by adjusting the amount of aeration, you can control the conversion ratio of ammonia nitrogen and nitrate nitrogen, thus reducing the total nitrogen content.
4, by increasing the internal reflux ratio, can be more ammonia nitrogen and organic matter back to the anoxic section, to promote denitrification, thus reducing the total nitrogen content.
5, replace or increase the filter media, if the biochemical tank in the filter media failure or insufficient, you can replace or increase the filter media, improve the filtration effect, reduce the total nitrogen content.
6, in the biochemical process, you can add some chemicals, such as oxidizing agents, reducing agents, etc., to promote the conversion and removal of ammonia nitrogen and organic nitrogen, so as to reduce the total nitrogen content.
7, before entering the integrated wastewater treatment equipment, you can strengthen the front-end pretreatment, such as removing suspended solids, removing organic matter, etc., to reduce the total nitrogen content.
8, after the integrated wastewater treatment equipment, you can increase the back-end depth treatment, such as activated carbon adsorption, ion exchange, etc., to further remove total nitrogen.
It should be noted that the above measures need to be selected and adjusted according to the situation in order to achieve the best treatment effect. At the same time, it is also necessary to monitor the total nitrogen content in the sewage on a regular basis to detect problems and deal with them in a timely manner.
