[0002] During the development of oil and gas fields, especially during the construction of gas wells and oil well production measures, a large amount of waste liquid will be discharged to the ground, and a large amount of produced water will be generated during the oil field production process. These oil field waste liquids contain both clay particles brought out from the formation and pollutants such as additives in crude oil and measure fluids, so the wastewater needs to be treated and filtered.

[0003] After searching, the patent announcement number CN218784645U discloses an oil and gas field sewage treatment device that is easy to replace components, including a filter box, a sewage inlet pipe is connected to the top of the filter box, the sewage inlet pipe extends to the filter box and is connected to multiple water distribution pipes, the end of the water distribution pipe is connected to a sealed filter cartridge, the water distribution pipe extends to the sealed filter cartridge and is connected to a first connecting pipe, the first connecting pipe is connected to a filter element, the bottom of the sealed filter cartridge is connected to a second connecting pipe, the filter element and the second connecting pipe are plug-connected, the second connecting pipe is connected to a filter discharge pipe extending to the outside, and the bottoms of multiple sealed filter cartridges are all connected to drain pipes. The advantage of the utility model compared with the prior art is that the utility model can perform simultaneous filtering through multiple sealed filter cartridges and filter elements, and the filter elements in the form of threads and kits can be easily disassembled and replaced, and there is no need to stop the filtering operation during the replacement process.

[0004] The CN218784645U in the prior art can be easily disassembled and replaced through the filter element in the form of threads and kits during use, and there is no need to stop the filtering operation during the replacement process. However, most of the existing sewage treatment devices directly filter the water body, which will cause a lot of particulate matter and debris in the sewage. Direct filtration cannot be used for a long time and will cause internal blockage. Therefore, it is necessary to perform a complete treatment before filtering to prevent the particulate matter and debris from excessively affecting the filtering and discharging.

When personnel treat gas field sewage, the sewage is precipitated in the filter water box and then limited by the limit frame sliding sleeve on the guide rod. When limiting, the limit frame is installed on the screw rod through a thread, so that the personnel can open the driving mechanism to drive the screw rod to rotate, and the limit frame can be driven to move up and down in the filter water box according to the rotation direction of the screw rod, so that the limit frame drives the connecting pipe to move up and down, so that the water inlet position can be adjusted according to the actual height of the sewage sediment, so as to avoid the extraction of sediment affecting the later sewage filtration treatment, thereby meeting the later gas field sewage treatment.
