Embodiment

[0033] The magnetic recovery device of the present embodiment is as figure 1 As shown, it includes: a belt 2 with a slope, a water distributor 1 for uniformly distributing the liquid on the belt is arranged above the slope, and the bottom of the slope is at least partly located in the magnetic field area 7;

[0034] A magnetic seed recovery area 8 is set under the bottom of one end of the slope top of the belt 2, and a discharge port 11 is set under the bottom of the other end;

[0035] A rolling brush 4 and / or a spraying device 5 for mechanically separating the magnetic seeds from the belt are arranged between the magnetic seed recovery area 8 and the discharge port 11 .

[0036] figure 1 Among them, the discharge area 9 above the discharge port 11 is provided with a magnetic rod 6. After the sewage with added magnetic seeds passes through the magnetic seed recovery area 8, a very small amount of magnetic seeds flows into the clean water discharge area 9 together with the cl...

Abstract

The invention relates to a recovery and sewage treatment method, belongs to the technical field of sewage treatment, and in particular, relates to a magnetic recovery and sewage treatment method including the steps: sewage is uniformly distributed on a belt slope surface having the back face provided with a magnetic field region, and magnetic seeds falling off from a belt due to gravity are recovered by using a magnetic seed recovery region arranged below the bottom of a slope top. Therefore, the device, the method and the system adopt the multiple recovery technologies such as brush rolling, spraying and the like, have the advantages of high magnetic seed separation, recovery and utilization rate and large sewage treatment amount; a plate structure is adopted, and the occupied space is small.

Description

technical field [0001] The invention relates to a recovery and sewage treatment method, belonging to the technical field of sewage treatment, in particular to a magnetic recovery and sewage treatment method. Background technique [0002] Water resource pollution is already a major problem facing our country. Compared with the traditional sedimentation method, filtration method, biological oxidation method and other methods, magnetic separation technology has brought new hope to sewage treatment. It has simple structure, convenient operation, It has the advantages of fast speed, small investment, high efficiency and little secondary pollution. [0003] The principle of magnetic separation is: by adding magnetic seeds to the sewage, the non-magnetic suspended solids are combined with the magnetic seeds under the action of coagulants and coagulants to form micro-magnetic flocs and flow into the magnetic separation device. Under the force of a strong magnetic field, the micro-m...
