Spherical porous filler and electrolytic oxidation system for treating organic matters in heavy salt water

Abstract

The invention discloses a spherical porous filler and an electrolytic oxidation system for treating organic matters in heavy salt water. The spherical porous filler is prepared by the following method: cleaning blast furnace fly ash, performing drying, performing grinding with a ball mill, mixing the ground blast furnace fly ash with clay, adding deionized water, and performing granulating; and performing sintering under the protection of nitrogen, and cooling to room temperature to obtain the spherical porous filler. The spherical porous filler provided by the method can greatly promote the ozonation efficiency. The filler can serve as a three-dimensional conductive electrode in an advanced oxidation device for treating organic matters in high-salinity water, the electrolysis area is greatly increased, and efficient electrolysis treatment of the organic matters in the high-salinity water is achieved. The main components in the raw materials of the spherical porous filler are iron element and carbon element, the iron element and the carbon element can form a Fe-C micro-electrolysis system in water, iron ions formed in the micro-electrolysis process can promote ozonolysis, the forming speed of hydroxyl free radicals in water is increased, and the catalytic ozonation efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of organic matter treatment in high brine. Specifically, it relates to a spherical porous filler, an advanced oxidation device for treating organic matter in high-salt water, and an electrolytic oxidation system for treating organic matter in high-salt water. Background technique [0002] With the shortage of water resources, people pay more and more attention to the treatment and recycling of high-salt wastewater. High-salt organic wastewater refers to organic wastewater with a total salt content of at least 1%. These wastewaters mainly come from the discharge of seawater in the process of direct utilization, such as mariculture wastewater, discharges from certain industrial industries, such as the production of chemical reagents, chemical wastewater from petroleum, printing and dyeing enterprises, and concentrated water from desalination processes. A major feature of this type of wastewater is its complex composit...

AI Technical Summary

Problems solved by technology

However, the low carbon-nitrogen (C / N) ratio and the instability of influent water will lead to the need to add additional carbon sources during the treatment process, and there may be excessive carbon source dosing. The high salt content in high-content brine content, especially a large amount of chloride ions, greatly curbed the growth of microorganisms, making it difficult for the bioreactor to operate stably

Therefore, biological treatment methods often cannot operate for a long time

Therefore, high salinity organic water becomes a difficult problem in wastewater treatment
