Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] See also Figure 1-Figure 3, a mobile construction site sewage treatment device, including a treatment box 2, a mounting base 1 is provided at the bottom of the treatment box 2, and the mounting base 1 is used to realize the detachable setting of the device as a whole, so that the device can be conveniently transferred according to the construction site. A partition 6 is provided in the treatment box 2, and the partition 6 can separate the internal space of the treatment box 2 into two cavities, a large cavity and a small cavity. The large cavity and the small cavity are respectively used to treat sewage and store treated sewage. Two water inlet valves 201 are provided on the left side of the treatment box 2, which are symmetrically distributed front and back. A filter 28 is provided in the water inlet valve 201. The filter 28 can be used to remove most of the debris when the sewage enters the treatment box 2. An air pump 4 is provided on the front side of the treatment box 2 through a fixing frame 3, and an aeration pipe 5 is provided in the large cavity of the treatment box 2. The aeration pipe 5 is connected to the air pump 4, and two valve bodies 7 are symmetrically distributed in the front and back at the lower part of the partition 6. A vent is provided on the top of the treatment box 2, and the irritating gas generated by aeration is discharged from the vent. A limiting frame 8 is provided on the top of the treatment box 2, and a first baffle 9 is slidably provided on the limiting frame 8. The first baffle 9 is used to seal the vent. The left and right parts of the first baffle 9 are both sleeved with a first elastic member 10, and the two ends of the first elastic member 10 are respectively connected to the first baffle 9 and the treatment box 2. A fixing sleeve 11 is provided on the top of the treatment box 2 by screw connection, and the fixing sleeve 11 is provided with two ventilation plates 12 symmetrically distributed in the upper and lower parts. Activated carbon 13 is provided between the two ventilation plates 12. The activated carbon 13 is located above the vent to purify the irritating gas.

[0027] After pretreatment, the sewage from the living area enters the large cavity through the water inlet valve 201. Then the air pump 4 is started, and air is input into the large cavity through the aeration pipe 5, so that the sewage in the large cavity contacts with the air and is oxygenated, and the sewage is stirred, thereby strengthening the contact between the internal organic matter and the microorganisms and dissolved oxygen. As a result, the debris in the water floats up. During this period, the irritating gas in the large cavity continues to increase. When a certain pressure value is reached, the limit frame 8 is pushed open by the irritating gas, and the irritating gas is discharged from the vent and the toxic and harmful substances are absorbed by the activated carbon 13 before being discharged, thereby achieving purification. The aerated water enters the small cavity from the valve body 7 for storage and discharge.
