The accommodating space 24 is for collecting waste liquid discharged from the second water filter 12 . Wherein, the waste liquid contains a plurality of impurities that are not filtered by the second water filter 12, and the impurities are deposited on the bottom end 22 of the sump 20 by the influence of gravity.

The water pumping device 30 is disposed between the sump 20 and the first water filter 11 , and the water pumping device 30 pumps the waste liquid containing impurities from the bottom end 22 of the sump 20 to the first water filter 11 . . In the present embodiment, the water pumping device 30 includes a vertical pump 31, a water suction pipe 32, and a drain pipe 33. The water suction pipe 32 is disposed between the bottom end 22 of the sump 20 and the vertical pump 31.

The impurity portion of the waste liquid is deposited at the bottom end 22 of the sump 20. The vertical pump 21 pumps the waste liquid, the impurities suspended in the waste liquid, and the impurities deposited on the bottom end 22 of the sump 20 to the first water filter 11 via the water suction pipe 32 and the drain pipe 33. The first water filter 11 can filter out about 80% to 90% of impurities and oil slick. After the first water filter 11 completes the filtration, the waste liquid is discharged into the sedimentation tank 41 closest to the sump 20. The waste liquid still contains from one to two percent of impurities and oil slick after being filtered through the first and second water filters 11, 12. In the sedimentation tank 41 closest to the sump 20, heavier impurities in the waste liquid are first precipitated at the bottom of the sedimentation tank 41, and a lower density substance such as oil slick is suspended on the surface of the waste liquid. Since the first water filter 11 continuously discharges the relationship of the waste liquid into the sedimentation tank 41, the amount of the waste liquid gradually increases. When the height of the waste liquid reaches the height of the recovery hole 231 of the side wall 23 of the sump 20, the oil floating above the waste liquid passes through the recovery hole 231 and returns to the accommodating space 24 of the sump 20. After the liquid level of the waste liquid exceeds the partition 45, The waste liquid flows from above the partition 45 to the next settling tank 42, and so on, and the waste liquid flows sequentially into the sedimentation tanks 43, 44. Most of the impurities which are not filtered by the first and second water filters 11, 12 are precipitated in the precipitation tank 41, and only a very small portion is precipitated in the precipitation tank 42. The amount of impurities in the waste liquid flowing into the sedimentation tanks 43, 44 is more than 1%, so that impurities in the waste liquid are almost filtered out. The turntable 52 of the water separator 50 retains the oil that has not been filtered by the first and second water filters 11, 12 or recovered by the sump 20, and the oil on the turntable 52 is further scraped by the scraping oil. The oil scraper is scraped so that the waste liquid that subsequently enters the sedimentation tanks 43, 44 does not carry any oil slick.

Please refer to the third drawing, which is a plan view of a second embodiment of the present invention. The second embodiment of the present invention is substantially the same as the first embodiment, except that the side wall 23 includes a plurality of plates 232 that surround the accommodating space 24 and the inner wall surface is a flat surface. One of the plates 232 defines the recovery hole 231. The pumping device 30 includes a submersible pump 34 and a drain pipe 35. The submersible pump 34 is disposed in the accommodating space 24 and has one end abutting against the bottom end of the sump 20, and the drain pipe 35 is disposed at The submersible pump 34 is between the first water filter 11. The second water filter 12 is disposed under the first water filter 11 , and the first water filter 11 discharges the filtered waste liquid into the second water filter 12 . The waste liquid filtered by the second water filter 12 is discharged into the sedimentation tank 41 closest to the sump 20.

Please refer to the fourth and fifth figures, which are respectively a schematic plan view and a side view of the filtering process of the second embodiment of the present invention. In the second embodiment, the waste liquid first flows into the accommodating space 24 of the sump 20, and the impurity portion of the effluent is deposited at the bottom end 22 of the sump 20. The submersible pump 34 is immersed in the waste liquid, and the waste liquid, the impurities suspended in the waste liquid, and the impurities deposited on the bottom end 22 of the sump 20 are directly pumped to the drain pipe 35, and then passed through the drain pipe 35. The drain pipe 35 sends the waste liquid to the first water filter 11. Wherein the first water filter 11 can filter out about 80% to 90% Impurities and oil slicks. The first water filter 11 discharges the filtered waste liquid into the second water filter 12. The waste liquid filtered by the second water filter 12 is discharged into the sedimentation tank 41 closest to the sump 20. After the waste liquid is treated by the plurality of precipitation tanks 41, 42, 43, 44 and the oil-water separator 50 (the process is the same as the first embodiment, it will not be described), and the first and second water filters 11 and 12 are not used. Most of the filtered impurities from the first to the second are precipitated in the precipitation tank 41, and only a very small portion is precipitated in the precipitation tank 42, and the impurity liquid flowing into the sedimentation tanks 43, 44 is less than 1%. It does not contain any oil slick.

The present invention tapers toward the bottom end 22 due to at least the inner diameter of the inner wall surface of the side wall 23 of the sump 20 near the bottom end 22 of the sump 20. Thereby, the impurities in the waste liquid are not caught at the junction of the inner wall surface of the side wall 23 and the bottom end 22, and the impurities can be easily pumped to the first water filter 11 by the water pumping device 30 together with the waste liquid. The present invention can further achieve that the water storage volume of the sump 20 is kept stable, the water outlet hole 221 of the bottom end 22 of the sump 20 is not blocked, and the first water filter 11 recovers the debris of the metal containing iron, cobalt and nickel or its alloy. The recovery amount is increased, and the recovery amount of impurities of various weights recovered by the precipitation tanks 41, 42, 43, and 44 is improved, and the problem of the conventional filtration apparatus is improved at one time.

It is ensured that if the inner diameter of the inner wall surface of the entire side wall 23 is tapered from the open end 21 to the bottom end 22, it is ensured that the inner wall surface of the entire side wall 23 does not have any dead angle for impurities to be contaminated therein.

Furthermore, the inner wall surface of the side wall 23 of the sump 20 is a curved surface. Thereby, the impurities can be more concentrated on the bottom end 22 of the sump 20, so that the impurities are more efficiently pumped by the pumping device 30 to the first water filter 11.

In addition, the recovery hole 231 is defined in the sidewall 23 of the sump 20 . By this, not The oil slick filtered by the first and second water filters 11, 12 also has the opportunity to be recycled and filtered again, increasing the recovery rate of the oil slick and reducing the filtration by the first and second water filters 11, 12. The amount of floating oil in the waste liquid increases the purity of the filtered waste liquid.
