[Abstract]:With the wastewater emissions and emission type synthesis and dyeing increasing, which caused the environmental pollution becomes more and more significant. Mesoporous silica due to its large surface area, abundant surface functional groups has become the choice of adsorbent and catalyst carrier. However, affected by the current price of silicon source, the manufacturing cost is high, failed to achieve large-scale production. To find suitable silicon source for preparing cheap mesoporous materials, has a broad market prospect in environmental governance. On the other hand, fly ash and silica fume as industrial waste, long-term lack of reasonable and effective use, resulting in a waste of resources, multiple problems of environmental pollution. The study of dielectric porous material and fly ash, silica fume, industry background, combined with present situation of dye wastewater pollution in China is serious, with fly ash and silica fume as cheap raw materials for the preparation of highly efficient adsorbent and catalyst carrier, to In addition to organic dyes in dyeing wastewater. The coal solid waste - fly ash as raw materials in ethyl acetate catalyzed by one step hydrothermal synthesis of spherical aluminum containing Al-MCM-41 mesoporous molecular sieve; in ferrosilicon smelting by-product of wollastonite as raw materials, using new technology and equipment of three different morphologies of mesoporous silica quickly preparing, and discuss other components, reaction temperature, reaction time and other factors to influence the morphology of mesoporous materials. The cationic dye methylene blue adsorption research object, four kinds of mesoporous materials. The adsorption performance is directly used as high efficiency adsorbent, spherical silica based mesoporous silica can be used as a catalyst carrier, two a heterogeneous catalyst by Fenton supported bimetallic oxides, and methylene blue as the degradation object, the catalytic performance of the catalysts for the synthesis of a systematic evaluation of specific design ideas and innovation. Points are as follows: (1) coal solid waste fly ash as raw materials, synthesis of spherical morphology containing mesoporous molecular sieve Al-MCM-41 by one-step hydrothermal method, the mesoporous molecular sieve production possible. The preparation of mesoporous molecular sieve, adsorption of cationic dye wastewater has great application prospect in dye the wastewater treatment field. (2) produced by metal or silicon ferrosilicon alloy industry smelting by-product silica as raw materials, using medical autoclave reactor, by controlling the adding amount of ethyl acetate catalyst, the rapid synthesis of three different morphologies of mesoporous silica hydrothermal synthesis of mesoporous silica particles can be adjusted in micron level and size. (3) choose light, porous, strong adsorption capacity, large surface area of spherical silica based mesoporous silica as the carrier, through the load of iron - copper or copper - manganese double metal oxide, development Two novel two-component heterogeneous Fenton catalyst for dye wastewater treatment. The Fe Cu/SF-S-MCM catalyst, the synergetic effect between Fe2O3 and CuO load can accelerate the reaction. For the MnCu/SF-S-MCM catalyst, the special structure of Mn and Cu load with spinel form in CuMn2O4, which has adsorption performance and good catalytic performance. This paper obtained the following conclusions: (1) using fly ash as raw materials, CTAB as surfactant, ethyl acetate as catalyst by one-step hydrothermal method successfully synthesized with cellular morphology of aluminum spherical mesoporous Al-MCM-41. structure characteristics of the single factor experiment showed that the preparation of ethyl acetate amount not only affects the mesoporous molecular sieve particle size, but also has a certain influence on the structure of mesoporous molecular sieve; crystallization temperature and time have some influence on the particle dispersion and ball Degrees. Through the single factor experiment, the optimum process conditions of spherical mesoporous adsorbent obtained: ethyl acetate was added to 10 mL, the crystallization temperature of 60 C, the crystallization time was 12 h. (2) with wollastonite as raw material, CTAB as surfactant, using new technology equipment, rapid synthesis of mesoporous oxide two silicon, the time of crystallization from the original 48 h greatly shortened to 1.5 h. by controlling the added amount of ethyl acetate catalyst, obtained three different morphologies of mesoporous silica, the study also found that ethyl acetate addition products not only affect the morphology also affected the ordered mesoporous material. The influences of /CTAB molar ratio of silica fume by single factor experimental design, crystallization temperature the water content of the system, and influence the crystallization time and adding inorganic salts of five factors on the morphology of mesoporous silica particles, adjusting the size and morphology of mesoporous silica through the above experimental factors. (3) the static adsorption experiment is discussed. The initial pH value of solution, adsorption time, initial concentration of solution and the effect of temperature on the adsorption of four kinds of adsorbent. The experimental results show that the pH value of the solution increased to four kinds of adsorbents on the adsorption of Ya Jiaji blue, and when the pH is 10 the maximum absorption capacity. At the same concentration, three kinds of silica fume based on mesoporous silica reached adsorption equilibrium in 30 min, faster than the Al-MCM-41 adsorbent (120 min). Four increase of adsorption amount increased with the initial concentration of Ya Jiaji blue, to reach adsorption equilibrium data. Simulation results show that four kinds of adsorbents on the adsorption process of Ya Jiaji blue are in line with the quasi two level dynamic model; the adsorption process is more accord with the Langmuir model for monolayer adsorption; adsorption thermodynamics research showed that the adsorption reaction is exothermic, spontaneous process, the degree of confusion in the reaction process decreases. (4) with spherical silica based mesoporous silica as the carrier two, loaded with iron Copper or copper - manganese - double metal oxides, the development of two novel two-component heterogeneous (class) Fenton catalyst.XRD and BET porous performance test showed that two new catalysts were retained.XPS MCM-41 mesoscopic structure of mesoporous silica matrix material. The results show that Fe and Cu elements in FeCu/SF-S-MCM composite catalytic materials respectively. In Fe2O3 and CuO metal oxides to the +3 price and +2 price form; while Mn and Cu MnCu/SF-S-MCM composite catalytic materials were performed with a +3 price and +2 price exists in the form of CuMn2O4 spinel structure. By changing the molar ratio of Fe/Cu, Mn/Cu, catalytic composite material preparation of different metal oxides and to determine the proportion of the load the best proportion (5). To investigate the effects of reaction conditions on the system of methylene blue degradation. The degradation experiment results show that the addition of catalyst FeCu/SF-S-MCM and H2O2 system, in the light of the reaction after 45 min sub The degradation rate of methyl blue was 98.38%; while adding MnCu/SF-S-MCM and H2O2 catalyst, the degradation rate of Ya Jiaji blue is slightly lower, as compared to those of 96.51%. under the same experimental conditions, SF-S-MCM matrix materials on the degradation rate of Ya Jiaji blue is only about 50%, indicating that the dual metal oxide matrix materials supported can greatly improve the degradation efficiency. Therefore, degradation Ya Jiaji blue in this experiment is the catalyst, oxidant (hydrogen peroxide) as well as the result of joint action of UV irradiation. (6) the optimum conditions of single factor experiments of Ya Jiaji blue dye wastewater degradation. With FeCu/SFS-MCM as catalyst, when Ya Jiaji blue initial concentration was 250 mg/L, adding 0.50 g/L catalyst, H2O2 the quantity is 0.3 mL, MB light degradation rate is up to 99.31% after 45 min reaction, with Ya Jiaji blue initial concentration increased the degradation rate decreased, FeCu/SF-S-MCM catalyst in the pH value of 5.0-9. 0 the range showed good catalytic performance for MnCu/SF-S-MCM catalyst, when the initial concentration of methylene blue was 250 mg/L, adding 0.50 g/L catalyst, the dosage of H2O2 is 0.5 m L, after reaction of 45min degradation rate was up to 98.22%. with increasing the initial concentration of methylene blue, the degradation rate decreased in.MnCu/SF-S-MCM catalyst pH is in the range of 3.0-9.0 showed good catalytic performance, greatly broaden the application range of pH.
