Acinetobacter for denitrification and decomposing ammonia in wastewater

An acinetobactersp and ammonia nitrogen degrading method of waste water are disclosed. It includes: adding at least one of C1-C6 organic substances with 0.01-1wt%, adding Acinetobactersp and waste water with 10 to the power 5-10 to the power 12 bacterium/ml concentration, and aerating under gas-water ratio 10-15. It achieves environmental protection, simple process, high efficiency.
