specific Embodiment approach 1
[0030] Embodiment 1: The preparation method of a coated ferrate composite material in this embodiment is carried out according to the following steps:
[0031] β-CD is added into ultrapure water, fully dissolved, then ferrate crystals are added, after uniform dispersion, cooled and dried, and finally fully ground to obtain a coated ferrate composite material, the β-CD and The mass ratio of ferrate crystals is 10:1.
specific Embodiment approach 2
[0032] Embodiment 2: The difference between this embodiment and Embodiment 1 is that β-CD is added to ultrapure water and dissolved by heating in a water bath.
[0033] Other steps are the same as in the first embodiment.
specific Embodiment approach 3
[0034] Embodiment 3: This embodiment differs from Embodiment 1 or 2 in that the ratio of the mass of β-CD to the volume of ultrapure water is (50-100) g:1L.
[0035] Other steps are the same as in the first or second embodiment.

The invention discloses a preparation method and application of a coated ferrate composite material, and relates to the technical field of advanced treatment of reclaimed water. The invention aims to solve the problems that the PPCPs are difficult to effectively remove by the traditional biological treatment technology, and the process is complicated and the removal cost is high due to the fact that the ultrafiltration technology for removing the PPCPs needs to be combined with treatment technologies such as oxidation, adsorption and the like. The method comprises the following steps: adding beta-CD (beta-cyclodextrin) into ultrapure water, fully dissolving, adding ferrate crystals, uniformly dispersing, cooling, drying, and finally fully grinding to obtain the coated ferrate composite material. The coated ferrate composite material is applied to an ultrafiltration system and is used for removing drugs and personal care products in sewage. According to the preparation method and application of the coated ferrate composite material, the coated ferrate composite material can be obtained.
Description
technical field [0001] The invention relates to the technical field of advanced treatment of reclaimed water, in particular to a preparation method and application of a coated ferrate composite material. Background technique [0002] In recent years, trace and stubborn new organic compounds such as pharmaceuticals and personal care products (PPCPs) have been widely used and directly enter the surface water environment and even the groundwater environment from urban residential water systems through urban sewage treatment plants without treatment, resulting in PPCPs. It has become a highly detected substance in tap water, reclaimed water and surface water, posing a great threat to the safety of aquatic ecosystems. Therefore, it is of great theoretical and practical significance to carry out the removal technology of PPCPs in recycled water for the sustainable development of urban sewage reuse in my country. [0003] It is difficult to effectively remove PPCPs through traditi...
