Problems solved by technology

In addition, the water quality of some raw water fluctuates greatly, and some high-salt wastewater and high-ammonia nitrogen wastewater suddenly enter the system, which can easily cause impact on the system, and even cause the system to collapse, resulting in the failure of the original basic reaction and sewage treatment.

Abstract

The invention relates to an ammonia nitrogen removal agent and a method for treating sewage by utilizing the agent, relates to the field of sewage treatment, and provides the ammonia nitrogen removalagent capable of improving a denitrifier propagation ability and with high shock resistance, and a method for treating the sewage by utilizing the agent. The ammonia nitrogen removal agent is preparedfrom the following components: 8 to 10 parts of arthrobacter globiformils, 15 to 20 parts of paracoccus denitrification, 10 to 12 parts of bacillus subtilis, 8 to 10 parts of nocardia amarae, 15 to 20 parts of nitrobacter winogradsky, 20 to 25 parts of pseudomonadaceae K50, 20 to 25 parts of pseudomonadaceae TR2, and 2 to 5 parts of snail stoste. The appropriate cultures are matched reasonably, so that a nitration-denitrification effect achieves the best; the snail slime is added into the agent, so that the cultures are promoted to grow and propagate, an ammonia nitrogen treatment effect is improved, and the shock resistance is improved; coconut oil fatty acid diethanol amide converts ammonium at an ion state into free ammonia, so that a denitrification progress of whole denitrification culture is accelerated; in addition, only N2 is produced during a denitrification process, and the production of N2O products in a sewage treatment system is reduced, so that the environment is protected.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an ammonia nitrogen removal agent and a method for treating sewage with the agent. Background technique [0002] Nitrogen pollution is one of the important causes of water eutrophication. Therefore, denitrification treatment of sewage plays an important role in maintaining clean water and preventing eutrophication. The process route of nitrification-denitrification is the current wastewater denitrification tooth treatment. The most important process route of the process, the key technical core of the process is nitrification, and its efficiency often determines the efficiency of the entire treatment system. [0003] Most of the currently used denitrification bacteria can only survive and function in a specific environment, but in the actual sewage treatment process, due to the coexistence and competition of other microorganisms, it is difficult for them to reproduce and become the...
