Abstract: Method and device for treating coking wastewater through denitrification and anammox are provided. The device includes an anaerobic reactor, an anoxic reactor, a sedimentation tank, and an aerobic reactor sequentially communicated, and a coking wastewater tank communicated with the anaerobic reactor through an influent pump. The present disclosure promotes the formation of microgranular sludge in the device through a composite powder carrier, and promotes sulfur-based autotrophic denitrification in anaerobic and anoxic zones through pyrite in the composite powder carrier and an additional sulfur source, and promotes anammox in the anaerobic zone through NO2?—N produced by sulfur-based autotrophic denitrification in the anoxic zone.

Abstract: A method for treating wastewater containing fluoroquinolone antibiotics by activating peroxyacetic acid heterogeneously with lanthanum ruthenate perovskite (LaRuO3) catalyst. The method includes: adding peroxyacetic acid to wastewater containing ciprofloxacin, mixing to obtain a peroxyacetic acid solution, adjusting a pH of the peroxyacetic acid solution; and adding lanthanum ruthenate perovskite to the peroxyacetic acid solution to obtain a mixed solution, and stirring the mixed solution in a constant temperature shaker, and removing the ciprofloxacin at a normal temperature.
