Description
Technical Field
The utility model relates to the technical field of wastewater treatment processes, in particular to a regeneration circulation system of a magnetic adsorbent.
Background
The magnetic separation technology is a physical separation method for separating substances with different magnetism by virtue of the action of magnetic force. Magnetic separation technologies (magnetic separation sewage treatment technologies) represented by super magnetic separation technology and magnetic precipitation technology adopt magnetic loading flocculation technology, and the flocculation effect is remarkably enhanced by the addition of magnetic media (or called magnetic seeds). The prior art shows that suspended matters, TP insoluble COD, heavy metals and other pollutants in the water body can be directly removed by the magnetic loading flocculation technology, but the pollutants such as ammonia nitrogen, TN, soluble COD and the like can not be directly removed by the magnetic loading flocculation technology for the solubility index in the water body. In the prior art, in order to remove the solubility index in the wastewater, the biochemical process can only be configured at the downstream of the magnetic separation process, so that in the actual operation process, the magnetic separation process is mainly used for removing suspended matters, TP insoluble COD, heavy metals and other pollutants in the water body, and the biochemical process configured at the downstream of the magnetic separation process is mainly used for removing the solubility index in the water body and has a certain effect, so that the magnetic separation process can be matched with the biochemical process for use, but the whole process flow is more complex, the cost is relatively higher, and some defects existing in the biochemical process cannot be avoided.
Based on the above, a sewage treatment system based on a magnetic adsorbent is designed, specifically, a magnetic adsorbent with an adsorption function is used as a magnetic medium, for example, a magnetic adsorbent capable of adsorbing soluble ammonia nitrogen is used as a magnetic medium (for example, a porous carrier with a chemical formula of Na 2Al2Si2O8·nH2 O, smCo 5 particles and Fe 3O4 particles existing in pores of the porous carrier, wherein N is more than or equal to 0), a magnetic adsorbent capable of adsorbing soluble COD is used as a magnetic medium (for example, fe 3O4 @chitin N-deacetylation group), and the like. The sewage treatment system not only can directly remove suspended matters, TP insoluble COD, heavy metals and other pollutants in the water body, but also can effectively adsorb solubility indexes in wastewater, such as ammonia nitrogen, soluble COD and the like, so that a biochemical process is not required to be configured to remove the solubility indexes in the water body. In the actual operation process of the system, the magnetic medium can firstly adsorb solubility indexes in the wastewater, then can form magnetic flocs together with non-solubility indexes in the wastewater, and finally the magnetic flocs can be separated out and discharged under the action of magnetic force to form magnetic sludge. In order to improve the economy of the sewage treatment system, the magnetic medium needs to be recovered from the magnetic sludge so as to be reused. Because the magnetic adsorbent with the adsorption function is adopted as the magnetic medium, the magnetic sludge generally comprises the magnetic medium with the adsorbed solubility index, the magnetic medium without the adsorbed solubility index, sludge and the like, and if the magnetic medium in the magnetic sludge is to be recycled, the magnetic medium with the adsorbed solubility index needs to be reduced and regenerated so as to recover the magnetic medium with the adsorption function, however, due to the difference in function, the existing regeneration system can achieve the aim of regenerating the magnetic medium only by separating the magnetic medium from the magnetic sludge, but when the magnetic adsorbent with the adsorption function is adopted as the magnetic medium, the existing regeneration system does not meet the regeneration requirement of the magnetic medium, and the prior art also lacks a regeneration system which can be matched with the sewage treatment system, so that the magnetic medium in the magnetic sludge is inconvenient to regenerate, and the problem is to be solved.

Similarly, in implementation, the deflocculating machine 508 may adopt an existing high-speed deflocculating machine 508, the deflocculating machine 508 may be communicated with each sub-discharge channel 301 in the discharge mechanism through the main discharge channel 304, the deflocculating machine 508 and the secondary magnetic recovery device 801 may also be of an integral structure, as shown in fig. 14, at this time, a deflocculating cavity of the deflocculating machine 508 may be communicated with the first cavity 502 of the secondary magnetic recovery device 801 through a communication hole, and the deflocculating cavity is communicated with the main discharge channel 304.
