Abstract

The invention discloses a method for optimizing the anaerobic ammonia oxidation operation process. A device is provided, including a water inlet tank, an anammox reactor, a pH adjustment tank, a temperature control device and a gas collection device, the anammox reactor is the main body, and the temperature control device controls the anammox reactor through the heat preservation water The temperature of the gas collection device is used to collect the gas collection. When the device is turned on, the water inlet pump controls the influent water to flow from the water inlet pool to the bottom of the anammox reactor. After the adjustment tank is adjusted by pH, it is used as the circulating liquid, and the circulating liquid is controlled by the circulating pump to flow from the upper part of the anammox reactor through the pH adjusting tank and then into the bottom of the anammox reactor. The above process is repeated for 30 to 50 days, and the Optimization of Anammox operation process. The method of the invention can effectively control the amount of greenhouse gas nitrous oxide generated in the anaerobic ammonium oxidation reactor, reduce secondary pollution, and has the advantage of convenient operation.

Description

technical field [0001] The invention belongs to the technical field of anaerobic ammonium oxidation technology, and in particular relates to a method for optimizing the anaerobic ammonium oxidation operation process, which can effectively reduce the amount of nitrous oxide generated in an anammox oxidation reactor. Background technique [0002] Anammox is a new biological denitrification technology in sewage treatment. Under anaerobic conditions, anammox bacteria use nitrite as an electron acceptor to oxidize ammonia nitrogen into nitrogen gas. The reaction does not require the participation of oxygen and organic matter, and is currently a relatively economical biological denitrification technology, which has sustainable development significance for its research and process development. [0003] The study found that the anammox bacteria will produce the greenhouse gas nitrous oxide while denitrification, which will cause secondary pollution to the environment. How to optimi...
