[0058] According to the above technical features, the working principle of the multi-bin skid-mounted water tank provided by this application in actual application scenarios is:

[0059] The water inlet 11 is connected to the external sewage pipeline, and different water treatment agents can be added to multiple independent stirring areas of the stirring chamber. The sewage valve and the stirring system are opened, and the sewage is injected into the first stirring chamber 52 through the water inlet 11. The sewage in the first stirring chamber 52 enters the third stirring chamber 54 through the first pipe 55 under the action of gravity, and the sewage in the third stirring chamber 54 enters the second stirring chamber 53 through the second pipe 56. As the sewage water level in the first stirring chamber 52, the second stirring chamber 53 and the third stirring chamber 54 increases, when the sewage water level in the second stirring chamber 53 is higher than the bottom of the first overflow tooth 22, the sewage in the second stirring chamber 53 flows into the buffer chamber 60 through the first overflow tooth 22;

[0060] The sewage in the buffer bin 60 enters the sedimentation bin 70 through the multiple jet holes 31. In this process, the sewage flow rate increases due to the small diameter of the jet holes 31, causing greater disturbance to the water body, thereby increasing the reaction process between the sewage and the water treatment agent, thereby making the reaction more complete.

[0061] Under the action of the sedimentation structure 90, the sewage in the sedimentation bin 70, the silt and flocs settle to the bottom of the sedimentation bin 70, and the upper clean water in the sedimentation bin 70 flows into the overflow bin 80 through the second overflow tooth 42;

[0062] The sewage undergoes secondary sedimentation in the first overflow bin 82, and the sewage in the first overflow bin 82 flows into the second overflow bin 83 through the connecting port 84. The upper clean water in the second overflow bin 83 is discharged from the water tank through the outlet 12. As needed, the outlet 12 is connected to a solid-liquid separation device, such as a filter press.

[0063] The skid-mounted water tank can meet the needs of sewage treatment sites with limited areas. The skid-mounted water tank can be installed flexibly according to the on-site conditions and has high reuse efficiency. The multi-bin setting structure of the skid-mounted water tank can extend the contact time between sewage and water treatment agent, so that the two can fully react, improve the reaction efficiency of the water treatment agent, reduce the workload of subsequent processes, and reduce production costs. The jet holes set in the matrix can increase the flow rate of sewage and play a stirring role, so that the water treatment agent and sewage can fully react.

[0064] The skid-mounted water tank provided by the present application not only has the storage function of a conventional water tank, but can also be used as a carrier for the coagulation and gel breaking of sewage front-end treatment. The design structure of multiple bins of the skid-mounted water tank can effectively prolong the retention time of sewage in the water tank, so that the sewage and water treatment agents can fully react in coagulation and gel breaking. At the same time, the setting of the skid-mounted structure can not only save installation work, but also improve the reuse efficiency of the water tank.
