The top of the left baffle wall 30 is connected to the top wall of the pool 10, and the top of the right baffle wall 40 is separated from the top wall of the pool 10 by a certain distance.

[0030] The partition wall 20, left baffle wall 30, right baffle wall 40, and the front and rear side walls of the pool body 10 together form a filtration space 60. A water inlet space 70 is formed between the left baffle wall 30 and the left side wall of the pool body 10, and a drainage space 80 is formed between the right baffle wall 40 and the right side wall of the pool body 10. The filter wall 50 is horizontally positioned within the filtration space 60 and spaced above the partition wall 20. The outer perimeter of the filter wall 50 is connected to the left baffle wall 30, right baffle wall 40, and the front and rear side walls of the pool body 10.

[0031] Please also refer to Figure 4 and Figure 5 The pool body 10 is a rectangular prism.

The pre-embedded pipe 11 is a cast iron pipe. A drain pipe 15 is located on the partition wall 20 corresponding to the reserved opening 12. One end of the drain pipe 15 communicates with the water inlet space 70, and the other end passes through the side wall of the pool body 10 and communicates with the outside. A sealing valve 16 is located at the end of the drain pipe 15 communicating with the water inlet space 70. Two through holes 31 are arranged side-by-side below the filter wall 50, corresponding to the filter space 60. Each through hole 31 is a square strip extending horizontally, with dimensions of 750 mm × 200 mm. In specific implementations, the number and size of the through holes 31 are not limited to this embodiment.

[0032] Please also refer to Figure 6 The filter wall 50 extends to the front and rear sides to connect with the side walls of the pool body 10. In this embodiment, the filter wall 50 can be a sand-free concrete wall. In specific implementations, the structure of the filter wall 50 is not limited to this embodiment; it can also be a structure where a filter mesh is covered with filter material. This filter mesh is a fiber mesh, specifically woven from polyphenylene sulfide fibers and heat-resistant coarse fibers. The filter material can be granular activated carbon, powdered activated carbon, bamboo charcoal, rice husk charcoal, carbon nanofibers, or artificial graphite. Please also refer to... Figure 7 and Figure 8 The partition 20 has multiple openings 21 arranged side by side in the drainage space 80. In this embodiment, there are 10 openings 21. Each opening 21 can be square, with a size of 100 mm × 80 mm.

[0033] The pool body 10 has a discharge pipe 18 extending to the outside on one side near its bottom end.

[0034] In use, wastewater is introduced into the inlet space 70 of the tank 10 through the pre-embedded pipe 11, enters the filtration space through the through hole 31 on the left baffle wall 30, is filtered by the filter wall 50, overflows from its top and flows into the drainage space 80, flows through the opening 21 on the partition wall 20 in the drainage space 80 to the bottom of the tank 10, and is finally discharged through the discharge pipe 18 for reuse. When the dirt in the inlet space 70 accumulates to a certain extent, the sealing valve 16 of the drain pipe 15 is opened, and the dirt is discharged through the drain pipe 15. At the same time, clean water can be flushed in through the reserved hole 12 to wash away the dirt accumulated in the inlet space 70.

[0035] Example 2: Based on Example 1, a filter element 90 is provided on one side of the pool body 10. The filter element 90 includes a fixed plate 91 provided on both sides of the pool body 10, a sliding column 92 provided on the upper side of the fixed plate 91, a sliding plate 93 slidably provided on the outer side of the sliding column 92, a filter screen plate 94 provided on one side of the sliding plate 93, a return spring 95 sleeved on the outer side of the sliding column 92, and a limiting plate 96 provided on the upper side of the sliding column 92. The two ends of the return spring 95 are respectively connected to the side wall of the fixed plate 91 and the side wall of the sliding plate 93. An inspection door is rotatably provided on one side of the pool body 10.

[0036] Preferably, the sidewall of the filter plate 94 is disposed in the insert plate 97, the insert plate 97 is inserted into the sliding plate 93 and slidably disposed therewith, the sidewall of the insert plate 97 is provided with an installation groove 98, the mounting block 99 is slidably disposed in the mounting groove 98, one end of the mounting block 99 passes through the sliding plate 93 and is slidably disposed therewith, the inner sidewall of the mounting groove 98 is provided with a compression spring 991, the two ends of the compression spring 991 are respectively connected to the sidewall of the mounting block 99 and the inner sidewall of the mounting groove 98.

[0037] As can be seen from the above, before use, insert the insert plate 97 on one side of the filter screen plate 94 into the matching slot on the upper side of the sliding plate 93. Then, the spring force of the compression spring 991 drives the locking block 99 to extend into one side of the sliding plate 93 to quickly fix and install the filter screen plate 94. During use, when the wastewater after preliminary filtration enters the filter screen plate 94 below the tank body 10 through the drainage space 80, it undergoes secondary filtration and screening through the filter screen plate 94. At the same time, when the sewage falls above the filter screen plate 94, it impacts the filter screen plate 94, causing the filter screen plate 94 to vibrate up and down, reducing the possibility of debris in the sewage clogging the filter screen plate 94 and extending the service life of the filter screen plate 94. When it is necessary to quickly disassemble and repair the filter screen plate 94, press the locking block 99 and pull out the filter screen plate 94 for quick disassembly, cleaning and repair.
