摘要
PROBLEM TO BE SOLVED: To provide an organic wastewater treatment system that is capable of efficiently removing nitrogen and phosphorus from organic wastewater, an organic wastewater treatment method, and a control program of the organic wastewater treatment system.SOLUTION: According to an embodiment, an organic wastewater treatment system comprises: a biological reaction tank equipped with an anaerobic treatment region, an adjustment treatment region and an aerobic treatment region in order; an ammonia concentration measuring device; a total nitrogen concentration measuring device; a total phosphorus concentration measuring device or a phosphate phosphorus concentration measuring device; and a control part. The adjustment treatment region is switchable to one or two or more atmospheres of anaerobic atmosphere, microaerobic atmosphere or aerobic atmosphere. Further, the region is a region where a range occupied with each atmosphere is adjustable. The control part has a control program which controls the adjustment treatment region so as to put priority to nitrification in removal of nitrogen, and remove phosphorus in the case where nitrification is sufficiently done.SELECTED DRAWING: Figure 1
