Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0020] It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", et...

Abstract

The invention relates to the technical field of sewage treatment, particularly to a magnetic microsphere and a preparation method thereof. The preparation method comprises the following steps: preparing ferrofluid from ferric trichloride and ferrous chloride under a certain condition; adding Fe3O4 into dissolved CTS-Lys, and dissolving to obtain a CTS-Lys solution; and dropwisely adding the CTS-Lys solution into the ferrofluid, and carrying out a mixing reaction to obtain the magnetic microspheres. According to the invention, the surfaces of the CTS-Lys magnetic microspheres are provided witha large number of amino groups, the CTS-Lys magnetic microspheres have good paramagnetism and high adsorbability to various heavy metal ions (such as Cu<2+>, Ba<2+>, Cr<3+> and the like), and the CTS-Lys magnetic microspheres can carry the captured heavy metal ions to move in a directional mode by changing a magnetic field so as to finally complete sewage treatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a magnetic microsphere and a preparation method thereof. Background technique [0002] Traditional sewage treatment technology mostly uses chemical precipitation to treat heavy metal ions. This method consumes a lot of chemicals, the treatment pool is relatively large, and solid-liquid separation is troublesome. Chitosan can well absorb pigments and Various heavy metal ions, but its cost is very high, also can't recycle reuse. [0003] With the increasing scarcity of urban water resources and the implementation of increasingly stringent sewage discharge standards, traditional treatment processes can no longer meet the needs of advanced treatment and reuse of urban sewage. Under the driving force of water reuse, membrane technology is used in urban sewage It has been widely used in recycling and has achieved good results. [0004] Reclaimed water obtained through membra...
