Background
With the continuous and rapid development of economy in China, the problem of environmental pollution is obvious, wherein sewage discharge is a big problem. The increasing living standard of people leads to the long-term water quality conditions of insufficient carbon source and high ammonia nitrogen in the inlet water of the urban sewage treatment plant, and the ammonia nitrogen in the outlet water of the sewage treatment plant exceeds the standard. Therefore, an additional carbon source, such as glucose, methanol, sodium acetate, etc., is required.
Glucose is used as a carbon source, the denitrification rate is slow, and the glucose is used to easily cause mass propagation of bacteria and increase the sludge production; the methanol is easy to be utilized by denitrifying bacteria, but has certain toxicity and higher price; sodium acetate is used as a carbon source, the response of the denitrification process is fast, the sodium acetate can be used as emergency treatment of a sewage treatment plant, but the price is high, and the sodium acetate cannot be used on a large scale.
In addition, according to research, the diversity of the florae in the environment of the single carbon source is gradually weakened, and the denitrification capability of the denitrifying florae is weakened by long-term feeding of the single carbon source. Because the carbon source input amount of the urban sewage plant is large, the development of a novel economic and effective carbon source is very necessary.
