The specific transformation method is to weld the tailgate of the container, and then cut the bottom and top of the container to connect up and down; it can realize the secondary utilization of abandoned containers, and the transformation is less difficult and low cost. Of course, it is also possible to directly produce the shelter with this structure and use it as the cabin body 1 .

The bottom of the inner wall of the cabin body 1 is equipped with a circle of ground beams 60 of equal height. There are four ground beams 60 connected end to end and installed on the bottom of the cabin body 1 by bolts to form a skid-mounted base, which is convenient to install and disassemble. .

The system also includes a grid treatment cabin 6, a flocculation cabin 7, an aeration cabin 8, and a circulation cabin 9 installed in the cabin body 1. The above four cabins are distributed in the cabin along the length direction of the cabin body 1. Body 1, and the bottoms of the four cabins are all installed on the skid-mounted base by bolts.

The grid treatment cabin 6, the flocculation cabin 7, the aeration cabin 8, and the circulation cabin 9 are connected to each other; specifically, the bottom of the grid treatment cabin 6 is connected to the upper part of the flocculation cabin 7, and the bottom of the flocculation cabin 7 is connected to the aeration cabin. The upper part of the air chamber 8 is connected, the bottom of the aeration chamber 8 is connected with the upper part of the circulation chamber 9, and the middle position of the circulation chamber 9 is connected with the bottom of the grid treatment chamber 6; the circulation between the four cabins is formed between the cabins, To carry out repeated cycle treatment of wastewater.

Among them, the grid treatment cabin 6 is provided with a lifting grid structure, which is used to remove larger suspended solids in the wastewater from the grid treatment cabin 6 by lifting and dumping; objects, including soil, straw, litter, stones, etc. in the soil, so the waste water produced by car washing will be mixed with the above-mentioned debris, and the straw, litter, stones and other debris can be removed through the grille treatment cabin 6 separate things.

There are three medicine boxes 23 suspended above the flocculation cabin 7, and coagulants, magnetic seeds, and coagulants are respectively placed in the three medicine boxes 23; the waste water after the larger suspended matter is separated by the lifting grid structure is discharged into the In the flocculation cabin 7, the medicines in the three medicine boxes 23 are thrown into the flocculation cabin 7 respectively according to the order of putting in the coagulant first, then putting in the magnetic seeds, and finally putting in the coagulation aid;

In detail, the mechanism of action between wastewater and coagulant is: the smaller suspended colloids and dispersed particles in wastewater form flocs under the interaction of molecular forces, and collide with each other and coagulate during the sedimentation process, and their size and quality are constantly changing. Increase, improve the sinking speed.

The mechanism of action with magnetic species is: magnetic substances or weakly magnetic substances in wastewater combine with magnetic species to increase specific surface area and attach to larger flocs to form magnetic flocs; it helps to reduce waste water Chromaticity, turbidity and other substances.

It should be noted that since most of the car body components are steel or iron structures, the oxides (such as rust) on the surface of the car body will fall off during car washing, resulting in a small amount of strong magnetic substances in the wastewater; Magnetic substances in wastewater.

The demagnetization technology in sewage is widely used in the treatment of steel industry wastewater such as hot steel rolling, continuous casting wastewater, cold rolling emulsion; different from the present invention, due to the proportion of strong magnetic wastewater in the wastewater produced by the steelmaking and ironmaking industry It can reach 98%, so it needs to be equipped with high gradient magnetic separation technology (HGMS technology), that is, Kolm-Marston type modern high gradient magnetic separator (High Gradient Magnetic Separator) ); the content of ferromagnetic substances in the waste water in the present invention is extremely low, so only a small amount of ferromagnetic substances can be removed by adding magnetic seeds.

Finally, the purpose of adding the coagulant is that when most of the suspended colloids, dispersed particles, and magnetic substances in the wastewater form magnetic flocs, there will still be a small amount of incompletely condensed impurities and drugs in the liquid wastewater; at this time The combination of unreacted drugs and uncoagulated impurities in liquid wastewater can be improved by adding coagulant aids to the flocculation cabin 7. On the one hand, the action efficiency of drugs can be improved, and a large amount of unreacted drugs can be avoided in wastewater; on the other hand, it can also It can further reduce the content of colloids, particles, and magnetic substances in wastewater.
