Abstract

The invention discloses a device and method for treating high-salinity sewage. The device comprises a regulating tank, a vertical three-phase fluidized bed, a biological aerated filter tank and a middle water tank, wherein the vertical three-phase fluidized bed comprises a reaction cylinder, a guide cylinder, a first aeration mechanism and a water discharge mechanism, and the first aeration mechanism comprises a first aeration fan, a plurality of aeration discs and a first aeration pipe. The device is characterized in that the sewage is treated through the vertical three-phase fluidized bed and the biological aerated filter tank, and salt-tolerant strains matched with the salinity in a reaction cavity and the biological aerated filter tank are cultured respectively to promote biochemical reaction. The device has the advantages that the salt-tolerant strains which are matched with the salinity in the vertical three-phase fluidized bed and the biological aerated filter tank are respectively cultured in the vertical three-phase fluidized bed and the biological aerated filter tank to allow the cultured salt-tolerant strains to match with sewage treatment so as to increase the sewage treatment efficiency; an aerobic zone is formed in the guide cylinder and an anaerobic zone and a facultative anaerobic zone are formed outside the guide cylinder to allow suspension filler to circulate in and out the guide cylinder to promote the alternate reaction of nitration and denitrification.

Description

technical field [0001] The invention relates to a high-salinity sewage treatment technology, in particular to a high-salinity sewage treatment device and a sewage treatment method thereof. Background technique [0002] High-salinity wastewater refers to high-concentration wastewater containing at least 3.5% total dissolved solids TDS (Total Dissolved Solid), which mainly comes from seawater and high-salt wastewater produced in industrial and agricultural production processes. In addition to organic pollutants, high-salt wastewater also contains a large amount of inorganic salts, such as Cl-, SO 4 2- 、Na + , Ca 2+ Plasma, the presence of these salts has a significant inhibitory effect on conventional biological treatment. For this kind of wastewater, the relatively mature and effective treatment processes mainly include physical and chemical methods, biochemical methods and their combined processes. Among them, the physical and chemical methods mainly include: electrochem...
