Abstract

The invention discloses a bacterial growth accelerant and a preparation method thereof. The bacterial growth accelerant is prepared from the following formula components in parts by weight: 4 to 5 parts of calcium salt, 13 to 15 parts of a metal salt solution, 3 to 5 parts of a humectant, 4 to 6 parts of a leavening agent, 3 to 7 parts of ferrite, 3 to 7 parts of hydroxylamine hydrochloride, 4 to 6 parts of lemon essential oil, 1 to 3 parts of hydroxylamine sulphate, 3 to 5 parts of copper salt, 5 to 7 parts of spermine, 6 to 10 parts of spermidine, 6 to 8 parts of xanthan gum and 10 to 12 parts of saccharose. The bacterial growth accelerant is simple in formula and easy to prepare, can be used in the cultivation process of nitrifying bacteria, and can also be directly dropped into a sewage disposal system, so that the nitrifying bacteria can be grown and propagated quickly in short time, and the cultured nitrifying bacteria are high in activity and high in impact resistance.

Description

technical field [0001] The invention relates to the technical field of bacterial culture, in particular to a bacterial growth promoter and a preparation method thereof. Background technique [0002] In the biological nitrogen removal method, whether it is the traditional nitrification-denitrification, or the new short-range nitrification-denitrification and short-range nitrification-ANAMMOX, the ammonia nitrogen needs to be removed through the nitrification of nitrifying bacteria. Nitrifying bacteria are chemotrophic microorganisms. Biological cells can only use the energy stored in the form of ATP, etc., and cannot directly use the free energy released by chemical reactions. In aerobic metabolism, ATP is mainly synthesized by oxidative phosphorylation of the respiratory chain. The efficiency of ammonia oxidation phosphorylation is very low, and the ATP that can be produced is very limited. The energy is mainly used for electron transition to a higher energy level, which m...
