Abstract

An integrated two-stage anaerobic ammonium oxidation coupled denitrification denitrification and carbon removal device and its control operation method. The top is provided with a packing layer and a perforated mesh baffle, and the side wall of the main body is provided with a water distributor, a mud discharge port, a measuring instrument, a sampling port, a mud inlet, a return port, and an inclined anti-backflow cut-off in sequence from bottom to top. Baffles, drain pipes, exhaust pipes. The present invention controls the range of ammonia nitrogen concentration to be 160-360mg / L, the ratio of ammonia nitrogen to nitrite nitrogen is 1:0.5-0.8, and the functional flora is domesticated and cultivated in two reaction chambers with different height-to-diameter ratios. The main flora in the nitrification reaction chamber are anammox bacteria and denitrifying bacteria, the auxiliary flora is ammonia oxidizing bacteria, and the anammox bacteria are mainly in the anammox reaction chamber. The longitudinal distribution characteristics of the flora and the control of reflux It overcomes the disadvantages of low impact load resistance and unstable operation of traditional bio-coupling devices.

Description

technical field [0001] The invention relates to an anaerobic ammonium oxidation coupled denitrification denitrification and carbon removal device and its control operation method, especially an anaerobic digestion of high ammonia nitrogen and low C / N ratio organic wastewater, anaerobic An integrated two-stage anaerobic ammonium oxidation coupled denitrification denitrification and carbon removal device for digestate water treatment and its control and operation method. Background technique [0002] The traditional nitrification-denitrification denitrification process needs to consume oxygen and organic carbon sources, but for some low C / N wastewater, it requires an additional carbon source when applied to this process. The treatment cost is high, the process is long, and the operation and management are relatively complicated. Oxyammox is a newly discovered autotrophic transformation process of nitrogen in the process of biological treatment. It refers to the process in whic...
