[0002] Sulfur-containing wastewater, including vessels and pipelines for oilfield production and water injection, and wastewater tanks, tanks, and pipelines in refinery drainage workshops, is severely corroded by this wastewater. This wastewater contains large amounts of H₂S, NH₃, and CO₂, as well as harmful ions such as Cl₁ and SO₄₄, numerous bacteria, and temperatures as high as 70-80°C. Some wastewater also contains corrosive agents such as phenols, requiring treatment. An existing sulfur-containing wastewater treatment device (Announcement No. CN221131133U) exhibits at least the following drawbacks during use:

[0003] In the above scheme, the wastewater is initially filtered by setting up a filter to facilitate the subsequent sulfur-containing wastewater treatment. However, in actual use, the filtering work will cause solid matter in the sewage to adhere to the inner wall of the device. If it is not cleaned frequently, the filter device will be blocked, affecting the continuity of sewage treatment. In addition, the filter device is often large in size, and manual cleaning is more troublesome. Therefore, a variety of oilfield sulfur-containing wastewater treatment devices have been developed.

A water outlet pipe 104 is fixedly connected to the outer side of the closed side wall, and one end of the water outlet pipe 104 is socketed with the inner wall of the scraper 201. In this embodiment, the inner wall of the processing housing 101 is provided with a plurality of chutes 109. The inner wall of the chutes 109 is slidably connected to the slide bar 205, so that the slide bar 205 is flush with the inner wall of the processing housing 101, facilitating contact between the scraper 201 and the inner wall of the processing housing 101. A feed pipe 203 is fixedly connected to the surface of the shielding plate 202 to facilitate the entry of sewage. A scraping handle 204 is fixedly connected to the outside of the shielding plate 202 to facilitate the staff to pull out the scraper 201. In addition, a water outlet 206 is provided on the scraper 201, and during the filtration operation, the water outlet 206 is connected to the water outlet pipe 104.

[0024] The processing housing 101 is equipped with multiple filter plates 302. The top side of the processing housing 101 is provided with multiple filter sockets 102. The outer edge of each filter plate 302 is fixedly connected to a ring of filter slides 304. The outer edge of each ring of filter slides 304 is slidably connected to the inner wall of the processing housing 101. Each ring of filter slides 304 and corresponding filter plates 302 correspond to a filter socket 102, and each ring of filter slides 304 and corresponding filter plates 302 extend out of the processing housing 101 through the corresponding filter socket 102. The top sides of all filter slides 304 are fixedly connected to a filter top frame 301. Two sets of symmetrically distributed lifting slides 105 are fixedly connected to the top side of the processing housing 101. The opposing sides of the two sets of lifting slides 105 are slidably connected to the sides of the filter top frame 301.

The filter plate 302 is provided with filter holes 303, and the size of the filter holes 303 decreases successively to avoid excessive burden on a single filter plate 302. At the same time, when the filter plate 302 is pulled out, the attachments on the filter plate 302 are pushed down by the filter scraper 103. The setting of the push-up slope 305 allows the attachments to slide down smoothly, and the filter scraper 103 is elastic, so that the filter slide 304 can suppress the deformation of the filter scraper 103, thereby entering and exiting the processing shell 101.
