Method for Efficiently Treating MB Dye Wastewater Using Renewable Ceramsite Filter Material

摘要

#$%^&*AU2020101509A420200903.pdf#####ABSTRACT The present disclosure relates to a method for efficiently treating MB dye wastewater by using a renewable ceramsite filter material. The method includes: dynamically adsorbing and treating an MB dye in wastewater by using a fixed bed process: feeding the ceramsite filter material into a fixed bed, injecting the MB dye wastewater, and then performing thermal regeneration treatment after reaching a saturated absorption. The prepared ceramsite filter material is reusable. The method of the present disclosure is available at normal temperatures and pressures, and does not cause secondary pollution such as sludges. A solid waste ceramsite filter material fixed-bed adsorption system has advantages of cheap and available adsorbents, good treatment effects, strong regeneration capacity of the adsorbents, and so on. Furthermore, the adsorbents may be repeatedly reused in the process of wastewater treatment, which greatly reduces costs of treatment of the dye wastewater.1.00.8 0.6 u?0.4- 5 mg/L -- 10 mg/L 0.2 15 mg/L -v- 20 mng/L -- 25 mg/L 0 100 200 300 400 500 600 700 Time/ miin FIG. 1 1.0 - - I- niL/nin -t-.5 m]L/midn -a-2 mU/min 0.8 - -v-2.5 mL/min -- 3 nL/nin 0.6& 0.4 0.2 0.0 0 100 200 300 400 500 600 700 Time/ min FIG. 2 1/3
