For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0026] One of the preferred embodiments of the present application is as follows: Figures 1 to 6As shown, an oil-water separation device for sewage treatment includes a separation box 1 and a partition plate 2 arranged on the inner wall of the separation box 1, the partition plate 2 divides the separation box 1 into a filter chamber 11 for filtering solid waste and a separation chamber 12 for separating oil and water; a filter assembly 3 is arranged between the separation box 1 and the partition plate 2, the filter assembly 3 can filter solid waste, the filter assembly 3 extends out of the separation box 1 and is locked by a locking structure 13, and the filter assembly 3 and the partition plate 2 are matched by a cleaning structure 21; when the filter assembly 3 is cleaned, the filter assembly 3 can be driven to move elastically downward to squeeze the filtered water in the separation chamber 12, and then the filtered water flows from the separation chamber 12 into the filter chamber 11 through the cleaning structure 21, and then the filter assembly 3 is flushed and cleaned by the filtered water, thereby improving the filtering effect, saving resources and reducing costs.

[0027] In this embodiment, Figure 2 and Figure 6 As shown, the filter assembly 3 includes a one-way filter 31 elastically mounted on the side of the partition plate 2 by a spring, and a drive rod 32 arranged on the side of the one-way filter 31; one end of the drive rod 32 extends out of the outer wall of the separation box 1 and is locked by the locking structure 13; when filtering, the sewage passes through the one-way filter 31 to filter the fixed garbage onto the one-way filter 31, and then the oily and water sewage passes through the separation chamber 12 for oil-water separation, thereby facilitating better oil-water separation and improving the processing efficiency.

[0028] In this embodiment, Figure 1 , Figure 2 and Figure 6 As shown, it should be known that a discharge port 14 is opened on the side of the separation box 1, and a valve is arranged on the side of the discharge port 14. The discharge port 14 is matched with the one-way filter 31, so that the solid waste on the one-way filter 31 can be discharged from the discharge port 14 through the discharge port 14, thereby facilitating the cleaning of the one-way filter 31, improving the filtering effect of the one-way filter 31, and thus improving the filtering efficiency; when cleaning the one-way filter 31, the solid waste on the one-way filter 31 can be cleaned and flushed with filtered water and discharged through the discharge port 14.

[0029] In this embodiment, Figure 2 and Figure 3As shown, a pair of connecting blocks are provided on the side of the separation box 1, and the locking structure 13 includes two clamping blocks 131 slidably mounted on the side of the separation box 1, and a screw 132 connected to the side of the corresponding connecting block by a thread; the two screws 132 are rotatably mounted on the side of the corresponding clamping blocks 131, and the two clamping blocks 131 cooperate with the driving rod 32; in a normal state, the two clamping blocks 131 clamp and fix the driving rod 32. When cleaning the one-way filter screen 31, the two screws 132 are rotated to drive the two clamping blocks 131 to move away from the side of the driving rod 32, so that the one-way filter screen 31 can be elastically moved down to the discharge port 14. At this time, the one-way filter screen 31 moves down to squeeze the filtered water in the separation chamber 12, and the filtered water flows into the filter chamber 11 through the cleaning structure 21, and then the one-way filter screen 31 is flushed and cleaned, which is convenient for better cleaning of the one-way filter screen 31, saving resources, reducing costs, and simple operation.

[0030] In this embodiment, Figure 2 and Figure 4 As shown, the cleaning structure 21 includes a baffle 211 installed on the side of the one-way filter 31, and an opening 212 opened on the side of the partition plate 2; the baffle 211 and the opening 212 match each other; initially, the baffle 211 can completely block the opening 212, so that the water in the separation chamber 12 cannot flow into the filter chamber 11, and the oily water can be separated normally; when cleaning the one-way filter 31, the one-way filter 31 elastically moves downward to drive the baffle 211 to move downward, and the baffle 211 moves downward to open the opening 212, so that the filter chamber 11 and the separation chamber 12 are connected, and the filtered water in the separation chamber 12 flows into the filter chamber 11 through the opening 212, so as to flush and clean the one-way filter 31, which is convenient for better cleaning and improves the practicality of the device.

[0031] In this embodiment, Figure 2 and Figure 5 As shown, it should be known that a mounting groove 22 is opened on the side of the partition plate 2, and an oil-water separation membrane 23 is arranged in the mounting groove 22. The oil-water separation membrane 23 is movably arranged to facilitate better replacement, which is convenient and quick; the oil-water separation membrane 23 divides the separation chamber 12 into a water filter chamber 121 and an oil filter chamber 122, so that the oily wastewater passes through the oil-water separation membrane 23 and the oil is filtered into the oil filter chamber 122.

[0032] In this embodiment, Figure 1 and Figure 2 As shown, it should be known that a slot is provided at the upper end of the separation box 1, and the slot is connected to the filter chamber 11, so that the sewage to be treated can be placed into the separation box 1 through the slot for separation treatment.

[0033] In this embodiment, Figure 2 and Figure 6As shown, a water outlet is opened on the side of the separation box 1, and the water outlet is connected to the water filter chamber 121. A valve is provided at the water outlet to facilitate the discharge of qualified treated water in the water filter chamber 121 through the water outlet.

[0034] In this embodiment, Figure 2 and Figure 6 As shown, an oil outlet is opened on the side of the separation box 1, and the oil outlet is connected to the oil filter chamber 122. A valve is provided at the oil outlet to facilitate the discharge and collection of the oil in the oil filter chamber 122 through the oil outlet.

[0035] It is understandable that if Figures 1 to 6 As shown, when normal sewage treatment is carried out, the valves of the discharge port 14, the water outlet and the oil outlet are all in a closed state to prevent leakage during filtration and affect the ecological environment. The solid waste in the sewage is filtered through the one-way filter 31, and then the oily and water sewage flows into the separation chamber 12. Under the action of the oil-water separation membrane 23, the oily and water sewage are filtered into the corresponding water filter chamber 121 and the oil filter chamber 122 respectively; when the one-way filter 31 is cleaned, the drive rod 32 can be pulled to elastically drive the one-way filter 31 to move down to the discharge port 14. When the one-way filter 31 moves down, the separation chamber 12 is in a relatively sealed state. At this time, the one-way filter 31 will squeeze the treated water in the water filter chamber 121 when it moves down. At this time, when the one-way filter 31 moves downward, it can move downward with the baffle 211, and the baffle 211 moves downward to open the opening 212. At this time, when the one-way filter 31 continues to move downward, the water in the water filter chamber 121 will be squeezed upward, and then can flow into the filter chamber 11 from the opening 212, thereby cleaning the one-way filter 31, and then open the valve of the discharge port 14, and the solid waste on the one-way filter 31 is discharged through the discharge port 14, so as to conveniently and resource-savingly clean the one-way filter 31 and save costs; at the same time, an opening 212 is provided to facilitate the formation of an unsealed state in the closed water filter chamber 121, so that the water in the water filter chamber 121 can be quickly discharged, thereby reducing the discharge time and improving the discharge efficiency.
