Embodiment 1

[0045] A method of treating antibiotic wastewater in this embodiment, comprising the steps of:

[0046] (1) Active carbon carrier for preparing a three-iron dioxide

[0047] The activated carbon particles for 60 mesh were used to dry 24 h at 105 ° C for 24 hours. Activated carbon particles after 10 g of dry treatment, 3.9 g fecl 3 · 6h 2 O and 1.4G fecl 2 · 4h 2 O Turn together in the beaker, adding 450 ml of ultrapure water dissolved at 70 ° C, and adding 6.5 g of PAC, 5 mol / L of NaOH solution 50ml, mechanically stirred for 1 h, standing for 2 h, removing the supernatant, dried overnight The precipitate was washed with ultrapure water until the supernatant of the wash was neutralized, and the precipitate was collected and the cooling of the dry air was obtained, and the activated carbon carrier loaded with the three iron oxide was obtained.

[0048] (2) Frengfunction is performed using the activated carbon carrier of the three-dimensional three-iron dioxide.

[0049] The activa...

Abstract

The invention discloses a nano ferroferric oxide loaded activated carbon carrier, a preparation method and application thereof in Fenton fluidized bed treatment, and belongs to the field of preparation and application of composite materials. Polymeric aluminum chloride forms micelle in a solution, nano ferroferric oxide particles are polymerized on the surface of granular activated carbon, the carrier is applied to a Fenton fluidized bed, generated Fe3+ can be crystallized and attached to the surface of the carrier, firm Fe(OOH) crystals are formed, therefore the amount of generated iron mud can be greatly reduced, meanwhile, the biodegradability of the wastewater is improved, and the COD (Chemical Oxygen Demand) removal rate and the residual antibiotic degradation rate of the wastewater are obviously improved.

Description

Technical field [0001] The invention belongs to the preparation and application of composite materials, and more particularly to a load-bearing nanodexide three-iron activated carbon carrier, a preparation method, and its application thereof in Ventonification bed treatment. Background technique [0002] my country is an antibiotic production country, which will emit large amounts of wastewater during antibiotic production, with a large amount of residual antibiotics, which will cause pollution to the environment, and even induce bacterial resistance. The traditional all-in-Wenrton technology is the most wide, but the technology has a narrow application range, Fe 2+ The amount of iron mud is large, the amount of iron mud is large, and the cost is high. [0003] For example, the application will be approved by the disclosure of China's invention patent application, disclosed on March 30, 2016, discloses a method of magnetic activated carbon integrated treatment of printing and dye...
