[0002] Oil and natural gas are important material resources in today's society. Many countries and regions are now actively developing and utilizing oil and natural gas. Drilling is required in the process of developing and collecting oil and natural gas, and the wastewater generated by drilling must be treated before it can be discharged to avoid polluting nature.

[0003] After searching, the Chinese patent application No. 202220310589.5 discloses a kind of oil and gas drilling wastewater treatment device, which discloses an oil and gas drilling wastewater treatment device and relates to the field of wastewater treatment. It includes a treatment box, a slag discharge assembly and a water treatment assembly. A treatment chamber is opened in the middle of the treatment box, and two slag discharge ports and water inlets are respectively opened on the inner walls on both sides of the top of the treatment chamber; the slag discharge assembly includes a power mechanism and a bearing mechanism, the power mechanism includes a forward and reverse motor and a threaded column, the bearing mechanism includes a bearing plate and a baffle plate, the bearing plate is arranged on the inner wall at the bottom of the baffle plate, and the inner walls on both sides of the baffle plate are provided with adjustment chutes, and both sides of the bearing plate are fixedly connected with guide sliders, and the two guide sliders are respectively connected with two adjustment chutes in a sliding manner.

When the wastewater is discharged from the water inlet 2 of the external sewage inlet pipe box, the wastewater is continuously discharged so that it can overflow the grille plate 7 and then flow into the treatment box 1 through the water inlet 2. At this time, the grille plate 7 can filter the large impurities in the wastewater and retain them in the filter box 3. Then the wastewater is discharged through the heavy The wastewater is forced to slide to the top of the guide block 13 for centralized static placement, so that the clay and other impurities in the wastewater can be precipitated. With the continuous addition of wastewater, it can gradually overflow the filter screen 12 and be discharged through the drain pipe 8. At this time, the precipitated wastewater can be secondary filtered through the filter screen 12, so as to further remove impurities, and the sediment flows along the guide block 13 to the sewage outlet 14 for gathering. At this time, the rotating motor 15 can be started to drive the connecting rod 16 to rotate, so that the spiral blade 17 can discharge the sediment evenly to the outside, thereby avoiding the problem of the sediment blocking the sewage outlet 14.
