Embodiment 1

[0016] 1. Configuration of iron-nickel-EDTA chelating solution

[0017] Determine that the concentrations of iron and nickel in the chelating solution are respectively 1.6×10 -3 mol / L, 3×10 - 4 mol / L, the iron element is provided by ferric chloride hexahydrate, and the nickel element is provided by nickel chloride hexahydrate. The concentration of EDTA is determined by the conservation of solution charge, which is 2.7mol / L×10 -3 mol / L.

[0018] According to the required volume of chelating solution, calculate and determine the quality of the drug taken by weighing. After the drug is fully dissolved, the iron-nickel-EDTA chelating solution is obtained. It should be left still for 48 hours before use. Ferric chloride 0.4325g, nickel chloride hexahydrate 0.0713g, edetate disodium 0.1005g, dilute with water, and dilute to 1L.

[0019] 2. Addition method of iron-nickel-EDTA chelating solution

[0020] The addition is based on the capacity of the fermentation material, the add...

Abstract

The invention relates to the technical field of anaerobic fermentation, in particular to a low-cost anaerobic gas generation promoter, a preparation method thereof and a use method of the promoter. The anaerobic gas generation promoter is iron-nickel and EDTA (ethylene diamine tetraacetic acid) chelating liquid, the concentration of iron in the chelating liquid is 1.6*10<-3>mol / L, the concentration of nickel in the chelating liquid is 3*10<-4>mol / L, and the concentration of EDTA is determined according to solution charge conservation and is 2.7mol / L*10<-3>mol / L. Cobalt deficiency is made up byimproving bio-availability of iron-nickel in anaerobic fermentation for the first time, and the EDTA is used as a chelating agent to improve the bio-availability in the anaerobic fermentation processfor the first time. The iron-nickel and EDTA chelating liquid is prepared by the aid of the EDTA serving as the chelating agent, and the bio-availability of iron-nickel is improved by the aid of theEDTA chelating liquid to make up cobalt deficiency, so that cost is reduced.

Description

technical field [0001] The invention relates to the technical field of anaerobic fermentation, in particular to a low-cost anaerobic gas production accelerator, a preparation method and a use method thereof. Background technique [0002] For a long time, people usually increase the efficiency of anaerobic fermentation by adding trace elements. The most commonly used elements are iron, cobalt and nickel. The iron element is usually provided by ferric chloride or ferrous chloride, and the cobalt element is usually provided by cobalt chloride. Nickel element is usually provided by nickel chloride. According to the price of non-ferrous metals on June 5, 2018, cobalt oxide (≥72%) is about 420,000 / kg; nickel chloride is about 33,000 / ton; ferric chloride is about 3,000 / ton, and the price of cobalt is far Much higher than iron and nickel. [0003] Both cobalt and nickel are transition metal elements, and both form ions with two positive charges in aqueous solution, and the atomic ...
