Embodiment 1

[0049] figure 1 It is a structural schematic diagram of an embodiment of the present invention. It includes a cylindrical cyclone reactor 1, which is tangentially connected to the sewage inlet pipeline 5, and a static pipeline mixer 6 is arranged on the sewage inlet pipeline 5, and the dosing system 7 will contain ferromagnetic flocculant The medicine is added into the static pipeline mixer 6 to fully react with the sewage. The cyclone reactor 1 is provided with a cylindrical magnetic drum 3 inside, and the magnetic wrapping angle of the magnetic drum 3 is 240 degrees. The upper and lower ends of the cylinder 3 have been waterproofed. The upper end of the swirl reactor 1 is a sealed structure, and a partition 18 is arranged above the inner magnetic drum of the swirl reactor 1, and there are several clear water overflow ports 19 on the partition 18. Above the partition plate 18 of the cyclone reactor 1 is a clean water tank 17 , and the mouth of the water collecting end of t...

Embodiment 2

[0052] figure 2 It is a structural schematic diagram of another embodiment of the present invention. Compared with Example 1, this embodiment adds a cylindrical cyclone separator 8 and a cyclone deflector 9, and the cyclone separator 8 is coaxially arranged with the cyclone reactor 1 and the magnetic drum 3 , to ensure good hydraulic load distribution, an opening is provided at the bottom center of the cyclone separator 8, and a cyclone deflector 9 is provided at the opening. The upper ends of the cyclone reactor 1 and the cyclone separator 8 are all sealed structures, and the cyclone separator 8 is hermetically passed through the sealing structure of the upper end of the cyclone reactor 1, so that the cyclone separator 8 is higher than the cyclone reactor. 1 setting. A partition 18 is arranged above the magnetic drum 3 in the cyclone separator 8 , and a plurality of clear water overflow ports 19 are arranged on the partition 18 . Above the dividing plate 18 of the cyclone...

Embodiment 3

[0055] Such as image 3 Shown is a schematic structural diagram of a preferred embodiment of the present invention. Compared with Embodiment 2, this embodiment adds a filter cartridge 10 and a recoil system inside the cyclone separator 8, and a water pipe 20 is arranged inside the filter cartridge 10, and the water pipe 20 communicates with the clean water tank 17 through the clean water overflow port 19 , used to discharge the clean water in the filter cartridge 10 into the clean water tank 17. The filter cartridge 10 is cylindrical, located on the outside of the magnetic drum 3, and arranged tangentially to the side wall of the magnetic drum 3. The filter cartridge 10 is driven by a transmission device and can rotate around its own axis. The axis of the filter cartridge 10 is aligned with the magnetic drum. 3 axes are parallel. Along the circumferential direction of the magnetic drum 3, the filter cartridge 10 and the mud scraper 4 are distributed alternately (such as Fi...

Abstract

The invention provides a sewage processing method, solving the problems of unsatisfactory effect of the sewage processing and the existing dead end of the sewage processing in a prior technology. The method comprises the following steps: adding medications into the sewage; flowing the mixed liquor into a cyclone reactor tangentially to perform cyclone separate; performing magnetic separation process on the mixed liquor after being cyclone separated through a magnetic roller. Meanwhile, the invention also provides a sewage processing device adopting the method; the device consists of a sewage inlet pipe, a clear water outlet pipe, a medication-adding system, a cyclone reactor, a magnetic roller and a scraper. The medication-adding system is connected with the sewage inlet pipe; an outlet end nozzle of the sewage inlet pipe is connected tangentially into the cyclone reactor, the cyclone reactor is a revolving body, the magnetic roller and the scraper are positioned in the cyclone reactor, the magnetic roller and the cyclone reactor are arranged on a same axial-line, and the scraper is used to scrape ferromagnetism mud cluster which is absorbed magnetically on the magnetic roller. In the invention, sewage purification has a good effect, the yielding water is clear, sewage processing method and sewage processing device of the invention are applicable to processing the sewage and the sewage containing grease and mud.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a fast and effective sewage treatment method and a device for treating sewage by using the method. Background technique [0002] With the vigorous development of science and technology and economy, in the production process of electric power, mining, papermaking and chemical industries, the discharge of sewage is also increasing year by year. In order to save precious water resources and not pollute the environment, it is necessary to carry out necessary purification treatment on sewage to remove solid debris, suspended matter, etc., so as to realize the purpose of turning sewage into useful water. [0003] In the current field of sewage treatment, there are various types and styles of sewage treatment methods and devices used for sewage treatment. Commonly used sewage treatment machines, such as the technical solutions described in Chinese utility model patents ZL200320108007.2 ...
