The purpose of adding glucose, sodium acetate and methanol during the biochemical commissioning of sewage is to increase the content of organic matter in wastewater, better cultivate microbial strains and improve the biodegradability and biochemical treatment rate of sewage.
glucose:
As a polyhydroxyaldehyde, glucose is easily soluble in water and is the main energy supply for microbial growth. Industrial glucose is used as carbon source in sewage treatment:
1. Increase the content of organic matter in water, better cultivate bacteria and improve the biodegradability of sewage.
2. It can effectively improve the affinity of sludge, and the effect is faster than that of urea.
3. Convenient storage and transportation.
shortcoming
1. The product price is high and the cost is high.
2. May cause sludge bulking.
