It is widely used in the biochemical stage of sewage treatment to provide nutrients for the flora of the anoxic pond aerobic pond, accelerate nitrification and denitrification, and thus remove total nitrogen in the water.
1. Quickly adapt to the new environment and shorten the adaptation time. Complex Carbon Source is a fast, low-consumption, non-toxic small molecule carbon source supplement. Compared with other conventional carbon sources, it has the advantages of stable chemical properties, fast denitrification rate, low sludge yield, fast adaptability of sludge strains, good denitrification effect and low treatment cost.
2. Promote the reproduction of bacteria, the composite carbon source contains bacteria accelerator and activator, which can make bacteria multiply rapidly, enhance the activity of bacteria at low temperature in winter, and increase 20%-40% compared with ordinary carbon sources.
3. Cost-effective, under the same conditions, the cost of a composite carbon source is higher than that of a single solid glucose or sodium acetate.
This is 20%-50% lower.
4. The low-temperature fast-acting acclimation time can be reduced by 10-15 days for ordinary carbon sources or sodium acetate, and only 5-7 days for composite carbon sources, which can greatly shorten the acclimation time and shorten the strain stagnation periodAdapt quickly to a new environment.
5. Compared with sodium acetate, the COD equivalent provided by the composite carbon source is higher and the freezing point is lower. It does not freeze at minus 25C, has good fluidity, and is suitable for low temperature use in winter. Beryllium acetate, which is easy to precipitate crystals, provides less COD and a higher sludge yield, and more importantly, it is easy to increase the conductivity and salinity of the biochemical system, which ultimately leads to high operating costs. Sludge production is less as compared to glucose!The composite carbon source can be used by denitrifying bacteria in biochemical sludge, and will not be used by microorganisms that cause sludge overgrowth such as filamentous bacteria. The most important thing is that compared with other traditional carbon sources, the composite carbon source can reduce the treatment cost by 10%-30% if it meets the standard
