[0004] In non-point source pollution control systems, brick structures are usually used. Their open nature makes it difficult for odor to leak out, providing a breeding ground for mosquitoes, making it difficult to effectively control non-point source pollution. In addition, their production period is long and there is a lack of necessary maintenance measures, which increases the risk of blockage in the municipal pipe network. The strength of this structure is not ideal and it is easy to break during use, which not only affects the use effect, but also prolongs the construction period and increases unnecessary costs.

[0029] The dirt trap assembly 21 includes a lower dirt basket 211 installed at the upper end of the housing 1, a water outlet 212 is provided at the center of the bottom of the lower dirt basket 211, and an upper dirt basket 215 is installed at the upper end of the lower dirt basket 211;

[0030] The filter assembly 22 includes a support 221 installed in the center of the lower dirt basket 211, an overflow line 222 is provided on the middle outer wall of the support 221, a water inlet hole 223 is provided on the lower outer wall of the support 221 and is located below the overflow line 222, an overflow hole 224 with a smaller bottom and a larger top is provided on the upper outer wall of the support 221 and is located above the overflow line 222, and an annular filter brick 225 is sleeved and installed on the lower outer wall of the support 221, and the annular filter brick 225 is located below the overflow line 222 and covers the water inlet hole 223;

[0031] The backflow prevention component 23 is arranged on the dirt blocking component 21 and is used to prevent backflow of water.

[0032] In this embodiment, when the amount of water coming from the upper end is small, the water entering the lower end of the lower dirt basket 211 is directly purified by the annular filter brick 225, and then enters the support 221 from the water inlet hole 223 and falls from the water outlet 212; when the amount of water coming from the upper end is large, since the annular filter brick 225 cannot be fully processed in time, the water overflows the upper end of the annular filter brick 225, enters the support 221 from the overflow hole 224 and falls from the water outlet 212; the water falling from the water outlet 212 falls on the baffle cover 233, and the baffle cover 233 is flipped downward by the gravity of the water, so that it is discharged into the lower end of the inner part of the outer shell 1 and then discharged from the drain port 3 to the municipal pipe network.

[0033] Specifically, the backflow prevention assembly 23 includes an axis frame 231 fixed to the bottom of the lower dirt basket 211 , a bracket 232 is pivotally connected to the axis frame 231 , a blocking cover 233 is fixed to the upper end of the bracket 232 , and a counterweight cylinder 235 is fixed to the lower end of the bracket 232 .

[0034] In this embodiment, when no water falls, the gravity of the counterweight cylinder 235 keeps the anti-backflow component 23 in a closed state at all times, thereby preventing mosquitoes and rats from passing through, preventing the sewer from backflowing, and avoiding the overflow of sewer odor.

[0035] Specifically, the backflow prevention assembly 23 further includes a sealing ring 234 fixed around the outer edge of the top of the blocking cover 233 .

[0036] In this embodiment, when the blocking cover 233 is turned upward, it fits with the bottom of the lower dirt basket 211 through the sealing ring 234, thereby improving the sealing performance of the water outlet 212.

[0037] Specifically, the anti-backflow assembly 23 further includes a cylinder cover 236 threadedly mounted on the counterweight cylinder 235 .

[0038] In this embodiment, a counterweight block of appropriate weight can be placed inside the counterweight tube 235 .

[0039] Specifically, the dirt retaining assembly 21 further includes a plurality of clamps 213 fixed around the top outer edge of the water outlet 212 .

[0040] In this embodiment, when the support 221 is installed in the lower dirt basket 211, the lower end of the lower dirt basket 211 is fixed by the clamp 213, so that the support 221 is fixed in the center of the water outlet 212 in the lower dirt basket 211, so that the position of the filter assembly 22 is accurately installed.

[0041] Specifically, the dirt-blocking assembly 21 further includes a shielding portion 216 provided at the center of the bottom of the upper dirt basket 215 , and hollow portions 217 provided at both sides of the bottom of the upper dirt basket 215 .

[0042] In this embodiment, the upper end of the support 221 is shielded by the shielding portion 216, thereby preventing garbage and water from directly flowing into the support 221, so that the garbage and water are intercepted by the hollow portion 217 and then flow downward.

[0043] Specifically, the dirt-trapping assembly 21 further includes first carrying holes 214 opened at the upper ends of both sides of the lower dirt basket 211 , and second carrying holes 218 opened at the upper ends of both sides of the upper dirt basket 215 .

[0044] In this embodiment, the upper waste basket 215 can be lifted up and removed from the lower waste basket 211 through the second carrying hole 218, and the lower waste basket 211 can be lifted up and removed from the housing 1 through the first carrying hole 214, and the garbage intercepted and collected inside can be poured out and cleaned.

[0045] The working principle and use process of the utility model are as follows: first, when water flows in from the upper part of the housing 1, the upper end of the support 221 is shielded by the shielding portion 216, thereby preventing garbage and water from directly flowing into the support 221, so that the garbage and water are intercepted by the hollow portion 217 and then flow into the lower part of the lower waste basket 211;

[0046] When the amount of water coming from the upper end is small, the water entering the lower end of the lower dirt basket 211 is directly purified by the annular filter brick 225, and then enters the support 221 from the water inlet hole 223 and falls from the water outlet 212; when the amount of water coming from the upper end is large, since the annular filter brick 225 cannot process all of it in time, the water overflows the upper end of the annular filter brick 225, enters the support 221 from the overflow hole 224 and falls from the water outlet 212;

[0047] Finally, the water falling from the water outlet 212 falls onto the blocking cover 233, and the blocking cover 233 is flipped downward by the gravity of the water, so that the water is discharged into the lower end of the inner part of the shell 1 and then discharged from the drain port 3 to the municipal pipe network.
