[0012] The present invention is described in detail below in conjunction with the accompanying drawings. As shown in Figures 1 and 2, a novel artificial wetland filter bed comprises a slag filler layer 1, which is filled at the bottom of the filter bed, and the upper side of the slag filler layer 1 is filled with a zeolite filler layer 2, a coarse sand filler layer 3 and a slag filler layer 4 in sequence from bottom to top; a filter sponge layer 5 is respectively arranged between the slag filler layer 1 and the zeolite filler layer 2, between the zeolite filler layer 2 and the coarse sand filler layer 3, and between the coarse sand filler layer 3 and the slag filler layer 4.

[0013] One of the new artificial wetland filter beds also includes a water-retaining component 6, and the water-retaining component 6 is arranged on the upper side of the slag filler layer 4, which is conducive to achieving the effect of protecting the slag filler layer and can effectively avoid the problem of the slag filler layer being washed away by sewage.

[0014] Among them, the water-retaining component 6 includes a bottom mesh plate 61, a water-retaining layer 62 is laid on the upper side of the bottom mesh plate 61, and a top mesh plate 63 is laid on the upper side of the water-retaining layer 62; through holes are longitudinally opened at the four corners inside the bottom mesh plate 61, and half-buried rods 64 are inserted into the inside of the through holes, wherein the upper ends of the half-buried rods 64 respectively penetrate the interior of the water-retaining layer 62 and the interior of the top mesh plate 63 from bottom to top; the upper sides of the outer walls of the half-buried rods 64 are respectively threadedly connected with fastening nuts 65, and the fastening nuts 65 are all located on the upper side of the top mesh plate 63; the surrounding parts of the lower side of the outer wall of the half-buried rod 64 are respectively integrated with anti-shift rods 66 from top to bottom, and the anti-shift rods 66 are all located on the lower side of the bottom mesh plate 61.

[0015] In the present embodiment, specifically, the outer ends of the semi-buried rods 64 are respectively arranged to be inclined upward.

[0016] In this embodiment, specifically, the bottom mesh plate 61 is laid on the upper side of the slag filler layer 4 .

[0017] In the present embodiment, specifically, the lower sides of the semi-buried rods 64 are respectively buried inside the slag filling layer 4 .

[0018] In the present embodiment, specifically, the anti-shift rods 66 are respectively buried in the interior of the slag filling layer 4. When protecting the slag filling layer 4, the operator can first bury the lower side of the semi-buried rod 64 and the anti-shift rod 66 in the interior of the slag filling layer 4 respectively. Since the outer ends of the anti-shift rods 66 are inclined upward, the anti-shift rods 66 can prevent the semi-buried rods 64 from being moved out of the slag filling layer 4. Subsequently, the operator can lay the bottom mesh plate 61, the buffer layer 62 and the top mesh plate 63 from bottom to top on the upper side of the slag filling layer 4, and make the upper ends of the semi-buried rods 64 pass through the bottom mesh plate 61, the buffer layer 62 and the top mesh plate 63 in turn. Finally, the operator The operator can thread the fastening nut 65 to the upper end of the semi-buried rod 64, so that the bottom mesh plate 61, the buffer layer 62 and the top mesh plate 63 are fixed on the upper side of the slag filling layer 4. At this time, when the sewage enters the filter bed, the sewage will impact the top mesh plate 63. Since the buffer layer 62 is provided on the lower side of the top mesh plate 63, the sewage can be evenly distributed through the buffer layer 62, so that the sewage can enter the slag filling layer 4 through the bottom mesh plate 61 more evenly, which can effectively prevent the slag filling layer 4 from being directly impacted by the sewage, thereby achieving the effect of protecting the slag filling layer 4 and avoiding the problem of the slag filling layer 4 being washed away by sewage.

[0019] In this embodiment, specifically, the bottom mesh plate 61 and the top mesh plate 63 are both made of stainless steel mesh plates.
