Provided is a method for processing a video. The method for processing the video can segment an initial video into a plurality of video clips, and calculate color temperatures of the plurality of video clips. For each target video clip in the plurality of video clips, the method can determine a color temperature adjustment coefficient of the target video clip based on a color temperature of the target video clip and a color balance correction coefficient thereof, and adjust a color temperature of at least one video frame in the target video clip by using the color temperature adjustment coefficient.

The present application relates to the field of sewage treatment, and specifically relates to a shortcut nitrification method for sewage treatment. The shortcut nitrification method for sewage treatment provided in the present application comprises the following steps: adding a shortcut nitrification accelerator to sewage. The shortcut nitrification accelerator comprises 2-30 parts by weight of an inorganic hydroxylamine and 0.1-20 parts by weight of an inorganic ammonium salt. The pH of sewage is 6.5-6.95. The shortcut nitrification method for sewage treatment provided in the present application can significantly increase nitrite accumulation rate, and control a biological nitrification reaction at a stage of nitrite accumulation, thereby facilitating a wastewater denitrification process, improving the wastewater treatment effect, and having good engineering application value.
