As temperatures drop, how do biological units respond?

As temperatures continue to drop, the water temperature in biological units also decreases. How to cope with biochemical operations under low-temperature conditions?
Steam heating pipes are distributed in the integrated regulation tank, and the valve openings are strictly controlled to maintain the temperature in the biological tank at around 20 degrees
Increase the steam usage to maintain an appropriate temperature. . . . . . . . . .
Increase the MLSS concentration to boost the total biomass.
Increase dissolved oxygen and deepen the reaction depth to compensate for the reduction in reaction depth caused by water temperature
Extend the residence time and sludge age, as well as the reaction time.
Covering the sewage tank will provide better insulation.
