Background
The Fenton oxidation technology is an effective technical means aiming at the rise of environmental problems, and is particularly widely applied to the field of treatment of organic wastewater difficult to degrade. The principle is H2O2In Fe2+Hydroxyl free radicals with extremely strong activity generated under the catalytic action of the catalyst can oxidize and degrade most organic pollutants into low-toxicity or non-toxicity micromolecule intermediate products, and even directly degrade the organic pollutants into CO2And H2O, near complete mineralization.
The current Fenton reaction method for sewage treatment generally comprises the following stages: the method comprises a water inlet buffering stage, a medicine adding pH adjusting stage, a Fenton oxidation stage and a flocculation precipitation stage. The equipment of the above stage is mostly built with a fixed foundation or fixed on the ground.

And the sewage source is far away from the traditional Fenton reaction equipment, and sewage can be treated only by long-distance transportation, so the traditional Fenton reaction equipment also has the defects of high power consumption and easy leakage in the transportation process. In addition, FeSO is often adopted in the traditional Fenton oxidation process4As catalyst, Fe2+A large amount of iron mud which can not be recycled is generated by oxidation in the reaction process, and the method also has the great disadvantage that the traditional Fenton reaction equipment can not avoid.

The first flocculation chamber 1411 is in communication with the UV-Fenton water treatment main system 12 (specifically, in communication with the effluent tank 124), and wastewater mixed with alkali liquor can enter the first flocculation chamber 1411. The second flocculation chamber 1412 and the first flocculation chamber 1411 are separated by a second retaining wall 1414, and a second channel 1415 is formed at the bottom of the first retaining wall 1211 to communicate the two. The third flocculation chamber 1413 and the second flocculation chamber 1412 are separated by a third partition 1416, and a third passage 1417 is formed at the top of the third partition 1416 to communicate the third and the third partition with each other. The third flocculation chamber 1413 is also in communication with the sedimentation tank 142. For example, the third flocculation chamber 1413 and the sedimentation tank 142 are partitioned by a wall provided with a fourth passage 1421 so that the third flocculation chamber 1413 communicates with the sedimentation tank 142. Since the second passage 1415 and the third passage 1417 have a height difference (i.e., a staggered arrangement), the stroke of the sewage is increased, thereby enhancing the flocculation effect.

The water inlet 1424 communicates with the flocculation tank 141 and receives sewage from the flocculation tank 141. After the sewage enters the water inlet part 1424, a part of the sediments will fall down to the cone-shaped collecting part 1422, and a part of the sediments will flow along the inclined tube assembly 1423 to the water outlet part 1425 with the clear liquid, but finally fall down to the cone-shaped collecting part 1422 again under the action of the inclined tube assembly 1423. The outlet 1425 is in communication with the filter 144, for example, via an outlet channel 1426. The chute assembly 1423 comprises a plurality of connected side-by-side chutes through which the water inlet portion 1424 and the water outlet portion 1425 communicate.
