The influence of the heating temperature of sewage on microorganisms is mainly reflected in the following aspects:
The growth rate of microorganisms: Temperature affects the growth rate of microorganisms. In the right temperature range, for every 10 degrees increase in temperature, the growth rate of microorganisms increases several times. Therefore, heating can increase the growth rate of microorganisms, thereby promoting the efficiency of wastewater treatment.
Type and number of microorganisms: Although heating can increase the growth rate of microorganisms, it does not significantly affect the variety and number of microorganisms in the mixture. In most controllable operating speed ranges, bell worms, nematodes, etc., will occur, but the mixture at 25 degrees is relatively rich in microorganisms.
Activity of microorganisms: Heating can increase the activity of microorganisms, making them more active in the treatment process of wastewater. For example, in wastewater treatment, the optimal temperature range for bacterial activity is 25-35, when the temperature is too high or when deodorization is added, it leads to heat accumulation, and when the temperature is above 50, aerobic nitrification and nitrification stop. Therefore, cooling measures such as water spraying are required.
In conclusion, the effect of the heating temperature of sewage on microorganisms is mainly reflected in the growth rate, species and quantity, and activity. In practical applications, it is necessary to select the appropriate heating temperature and treatment method according to the specific situation to promote the growth of microorganisms and the efficiency of treatment.
