Method for measuring and calculating ex-situ sludge oxygen consumption rate and alpha factor

The invention discloses a method for measuring and calculating an ex-situ sludge oxygen consumption rate and an alpha factor. The method comprises the following steps: deploying a measuring and calculating environment; the method comprises the following steps: acquiring dissolved oxygen concentration in a period through periodic acquisition of the dissolved oxygen concentration, the dissolved oxygen concentration in the period comprising a first dissolved oxygen concentration, a second dissolved oxygen concentration and a third dissolved oxygen concentration; loading an alpha factor and oxygen consumption rate calculation model, wherein the alpha factor and oxygen consumption rate calculation model is used for calculating the alpha factor through the sewage standard oxygen transfer rate and the clear water standard oxygen transfer rate; and transmitting the dissolved oxygen concentration in the period into the alpha factor and oxygen consumption rate calculation model to generate a calculated value of the alp
