Experiments show that carbon sources such as bluewave nitrogen removal nutrients can maintain lower operating costs and higher utilization rates of microorganisms for this carbon source. At the same time, it can also maintain the long-term stable discharge of ammonia nitrogen, total nitrogen, COD and other indicators in the effluent of the biochemical system.
