Organic composite powder carrier and application thereof in enhanced biological denitrification of municipal wastewater treatment

A method of use for enhancing denitrification of wastewater treatment in a biological nitrogen removal unit by applying an organic composite powder carrier comprising:

• controlling an input amount of the organic composite powder carrier and transmitting the organic composite powder carrier to a wastewater treatment biochemical pool through a feeder,
• wherein the organic composite powder carrier comprises a microbial carrier with a particle size of approximately 10 microns and an organic alternative carbon source,
• wherein the organic alternative carbon source is a short-chain polyhydroxyalkanoate ultrafine powder on a nanoscopic scale and is adsorbed on the microbial carrier based on surface energy of the microbial carrier caused by the particle size of the microbial carrier being larger than the particle size of the organic alternative carbon source,
• wherein the organic alternative carbon source is tightly adsorbed on the microbial carrier in advance of being transmitted to the wastewater treatment biochemical pool;
• and
• promoting a denitrification reaction by denitrifying bacteria after transmitting the organic composite powder carrier to the wastewater treatment biochemical pool.
