Embodiment Construction
[0026] Below in conjunction with accompanying drawing, the present invention is described further, and the production technology of the present invention is easy to implement for the professional.
[0027] my country's synthetic ammonia fertilizer industry has developed rapidly in the past two decades, and its annual output ranks first in the world. While producing products that meet the needs of industry and agriculture, nitrogen fertilizer enterprises also discharge a large amount of ammonia nitrogen-containing sewage, becoming a major sewage discharger. In order to treat and utilize the ammonia nitrogen sewage with a concentration lower than 500mg / L that cannot be recycled in the nitrogen fertilizer plant process, a sewage treatment plant, microalgae cultivation and processing equipment were built near a nitrogen fertilizer plant, and a sequencing batch reactor was used to couple with a photobioreactor. The method for treating nitrogen and phosphorus sewage is to purify the...
