Description
Technical Field
The invention relates to the field of environmental pollution control equipment, in particular to a biological cooperative electrocatalytic reactor.
Background
In recent years, haze problems have been increasingly attracting public attention, and it is an urgent issue to solve the problem of air pollution caused by the continuous growth of nitrogen oxides (nox). As more than 90% of NO in the flue gas is NO with extremely low solubility (the solubility of NO in water is only 4.7%), a complexation absorption-biological reduction method is proposed by students, and the method adopts a ferrous complex (hereinafter referred to as L-Fe II) as an absorbent to convert gaseous NO in the flue gas into liquid L-Fe II-NO, and then utilizes microorganisms to reduce the L-Fe II-NO into L-Fe II and pollution-free N2, thereby ensuring the regeneration of the absorbent and realizing the removal of the NO x. The electrode biomembrane method is based on the method, and the electrochemical effect is coupled, so that the NOx removal process is further enhanced. However, the higher oxygen concentration (more than or equal to 9%) in the flue gas can oxidize the L-Fe II into a ferric iron complex (hereinafter referred to as L-Fe III) without complexing NO, so that for the NO removal process, firstly, a high-efficiency strain for reducing the L-Fe III needs to be bred, namely, two reducing bacteria for reducing the L-Fe II-NO and the L-Fe III exist in a reactor. Early-stage researches show that ammonia nitrogen is the best nitrogen source for the growth of the two types of microorganisms, the nitrogen source deficiency directly affects the NOx treatment effect, and the cost required for directly supplementing the nitrogen source is high, so that the problem of how to improve the microbial activity and further improve the NOx treatment efficiency for the electrode biomembrane reactor is always to be solved urgently. Aiming at the problems, the development and design of the reactor which utilizes the existing resources to partially convert the target pollutant into the driving substance for the effective operation of the reaction system, thereby realizing the reduction of investment and convenient operation management has important practical significance. Chinese patent publication No. CN201634549U discloses a three-dimensional electrode biomembrane reactor for regenerating a nitrogen oxide complexing absorbent, and the patent utilizes a mixed bacterial film on the surface of cathode conductive particles to reduce EDTA-Fe II-NO and EDTA-Fe III in a nitrogen oxide complexing absorbent product to obtain EDTA-Fe II simultaneously by means of an electro-microbial effect, so that the regeneration of the complexing absorbent is realized, and the three-dimensional electrode biomembrane reactor has the advantages of low energy consumption and simple structure. Although the reactor is green and efficient, the popularization and application of the reactor in practice are limited due to difficult and high cost of microorganism domestication.
The zeolite-like imidazole ester skeleton compound (ZIFs) belongs to one common material in MOFs materials, has larger specific surface area and higher chemical stability, has uniform pore diameter, and has wide application in adsorption/separation, biological medicine and environmental treatment. The copper nano-particles used as the catalyst have the defects of easy oxidization, easy agglomeration and the like, the performance of the catalyst can be improved by loading the copper nano-particles on an organic framework with a large specific surface area, and the copper nano-particles can be loaded on ZIF-8 by utilizing the excellent performance of ZIFs materials and can be applied to the field of environmental pollution control. The research at the present stage shows that the metal nano particles are loaded on ZIF-8, and the obtained composite material has a certain reduction effect under the electrocatalytic effect. Therefore, on the basis, the material is applied to the field of NOx treatment, and NOx input by a reaction system is reduced into ammonia nitrogen (NH4+ -N) which is easy to be utilized by microbial growth through the electrocatalytic effect, so that the target pollutant is partially converted into a driving substance for the effective operation of the reaction system, the operation cost of a reactor can be greatly saved, and a new approach is provided for the recycling of NOx.
