Embodiment 1

[0016] 1,000 kg of microbial nutrition enhancer of the present invention contains 60 kg of trace elements potassium, 0.7 kg of cobalt, 0.4 kg of molybdenum, 0.2 kg of nickel, 0.05 kg of gallium, 0.08 kg of indium, and 15 kg of carbon source butyric acid. The specific preparation process of the nutritional enhancer is as follows: take 600 kg of water, add 15 kg of butyric acid, and prepare an aqueous solution of butyric acid at normal temperature; Various salts of trace elements such as 0.05 kg of gallium and 0.08 kg of indium are dissolved in butyric acid aqueous solution one by one; then add appropriate amount of water to adjust the content of each component to the corresponding value, and use acid to adjust the pH value of the solution to 5.00 , that is.

Embodiment 2

[0018] 1,000 kg of microbial nutrition enhancer of the present invention contains trace element potassium: 65 kg, cobalt: 0.75 kg, molybdenum: 0.45 kg, nickel: 0.25 kg, gallium 0.025 kg, indium 0.040 kg, carbon source butyric acid: 20 kg. Take 500 kg of water, add 20 kg of butyric acid, and prepare an aqueous solution of butyric acid at room temperature; Various salts are dissolved in butyric acid aqueous solution one by one; then add appropriate amount of water to adjust the content of each component to the corresponding value, and finally adjust the pH value of the solution to 5.50 with acid.

Embodiment 3

[0020] Microbial nutrition enhancer 1000 kg, including trace element potassium: 80 kg, cobalt: 1 kg, molybdenum: 1 kg, nickel: 1 kg, gallium 1 kg, indium 4 kg, carbon source butyric acid: 20 kg. Adopt the same preparation process as in Example 2, and finally adjust the pH value of the solution to 5.35 with acid.

Abstract

The invention discloses a microorganism nutrition enhancer which contains the following trace elements and components by weight: 3%-8% of potassium, less than or equal to 0.1% of cobalt, less than or equal to 0.1% of molybdenum, less than or equal to 0.1% of nickel, less than or equal to 0.05% of gallium, less than or equal to 0.08% of indium, 0.5%-2.0% of butyric acid used as a carbon source, and the balance of water. According to the enhancer, the two trace elements of gallium and indium are introduced into the formula, so the cultivation and domestication time of anaerobic activated sludge in an anaerobic biotreatment process is greatly shortened, and the stability of the whole anaerobic biotreatment process is also improved.

Description

technical field [0001] The invention relates to a microbial nutrition enhancer, in particular to a nutrition enhancer for improving the activity of anaerobic microorganisms used in the biochemical treatment process of wastewater anaerobic microorganisms. Background technique [0002] Using biochemical methods to treat domestic sewage and industrial wastewater has become the mainstream technology of contemporary wastewater treatment. Using anaerobic biochemical processes to treat high-concentration organic wastewater, such as PTA wastewater and beer wastewater, has achieved good results. Oxygen biochemical process is affected by external factors, its recovery performance is poor, and the effect of anaerobic microbial treatment is not very stable. These shortcomings have always been considered as relatively difficult links, thus restricting its further development and general use. [0003] The anaerobic biochemical treatment process of wastewater includes steps such as hydrol...
