Background
The deep bed filter tank is used as a post-filtration device in a water treatment process, adopts an anoxic biomembrane process, converts nitrogen elements in nitrate into a series of intermediate products through denitrifying bacteria, and finally reduces the nitrate in water into nitrogen, thereby reducing indexes of COD, BOD and the like of a water body.
After the sewage to be treated entering the deep bed filter tank is subjected to flocculation and precipitation processes, the content of organic matters is low, so that a carbon source needs to be supplemented and added into the filter tank during denitrification, and the denitrification is helped to be smoothly carried out. Not only the denitrification effect is influenced by the addition of the carbon source, but also the operating cost of the sewage treatment device is hooked with the addition of the carbon source.
If the carbon source is excessively added, the operation cost of the sewage treatment device is greatly increased in long-term operation, and COD and BOD indexes of the sewage after denitrification treatment have increased risks; if the adding amount of the carbon source is insufficient, the denitrification effect of denitrifying bacteria can be influenced, so that nitrogen elements in nitrate to be treated in the sewage are not completely converted, and the nitrate nitrogen in the treated sewage cannot reach the water treatment index specified by a regulatory agency.
