摘要： A method for degrading artificial sweeteners from sewage, the method including: 1) introducing sewage to a secondary sedimentation tank and precipitating sediments; 2) collecting a supernatant from the secondary sedimentation tank, adding a NaOH solution or a perchloric acid solution to regulate the pH; adding an H2O2 solution to the supernatant to adjust a ratio of a molar concentration of H2O2 to a molar concentration of the sweetener in the resulting mixed solution to be between 1:1 and 30:1; transferring the resulting mixed solution to a photoreactor, irradiating the mixed solution by ultraviolet light, and stirring the mixed solution for between 5 and 30 min; and adding a 1.5% w/w aqueous NaNO2 solution to the mixed solution; and 3) collecting and analyzing an effluent obtained from 2), contacting the effluent with ClO2 for reaction in a disinfecting tank, and discharging the product.

摘要： A coupling bioreactor in the form of a tower type seal structure filled with a suspended carrier. A water inlet pipe, an air inlet pipe, and a first microporous aerator are arranged at the bottom of the coupling reactor. The water inlet pipe is connected to a water distributor. The air inlet pipe is connected to the first microporous aerator. A gas inlet pipe and a second microporous aerator are arranged at the middle part of the coupling bioreactor and are connected with each other. An annular overflow weir is arranged at the upper part of the coupling bioreactor and is connected to a water outlet pipe. A gas outlet pipe is arranged at the top of the coupling bioreactor. The ratio of the height to the diameter of the coupling bioreactor is between 3 and 10.
