Benefits of technology

This invention relates to methods that use nickels (Ni) during chemical treatment processes used in wastewater processing systems like those described earlier. By increasing or decreasing the amount added into specific parts of these reactors based upon certain factors such as pH level, temperature, oxygen content, etc., it becomes possible to achieve stable carbon dioxide emissions from treated organics while also reducing nitrogen oxides released due to incomplete combustion caused by excessive addition levels.

Problems solved by technology

This patents discusses how improving the performance of aerobioclaking systems such as bacterial generations through adjustments made during their processing. It suggests studying specific types of compounds produced from these processes and comparing them against each other's effects towards reducing greenhouse gas emissions. Additionally, there may exist substances called vanadium oxide (VO2), which plays a role similar to carbon dioxide (C02). Vanadiums play a key part in this conversion process due to their ability to absorb light efficiently at lower concentrations than CO2. By measuring levels of both gases and metals, researchers aim to determine whether they affect the activity of yeast cells and optimize the operational condition thereof.

Embodiment 1

[0046] Practical example 1: Add hexahydrate nickel chloride to the CSTR anaerobic reactor in actual operation at a ratio of 0.04g / L at one time, observe the change of solvent load of COD, and do not stop feeding at the same time, keep the system running stably, specific implementation Data results (see image 3 ), COD rises to 15000mg / L under abnormal circumstances, after a single dose of 0.04g / L hexahydrate nickel chloride, within 5-10 days, the COD drops to the ideal state of 12000-13000mg / L, and maintains;

[0047] The method for utilizing nickel to stabilize the COD operation of the CSTR anaerobic reactor is to input hexahydrate nickel chloride into the CSTR anaerobic reactor at a rate of 0.04g / L at one time, and the COD can rise to 15000mg / L without stopping the feeding In the case of L, COD can be reduced to an ideal condition of 12000-13000mg / L within 5-10 days, which is conducive to stabilizing the COD value and maintaining the work quality, and nickel chlor

Abstract

The invention discloses a method for stabilizing COD operation of a CSTR anaerobic reactor by using nickel, belonging to the technical field of anaerobic fermentation systems for kitchen waste. The method specifically comprises the following steps: S1, installing a CSTR anaerobic reactor simulation device; S2, feeding the nickel element in a component mode; S3, conducting operation detection; and S4, conducting drawing comparison. According to the method for stabilizing COD operation of the CSTR anaerobic reactor by using nickel, nickel chloride hexahydrate is added into the CSTR anaerobic reactor at a time according to a proportion of 0.04 g/L, and the ideal condition that the COD is reduced to 12000-13000 mg/L within 5-10 days under the conditions that feeding is not stopped and the COD is increased to 15000 mg/L can be achieved, so a COD value is stabilized and working quality is kept; and compared with other trace elements, the nickel chloride hexahydrate has a price advantage, and since a single reagent is added, cost is low, operation is simple, and no other negative influence is caused to an anaerobic system.
