Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0022] A wastewater treatment filtration device with easy-to-replace filter cartridges includes a stepped base 1. A first wastewater treatment tank 2 is fixedly installed on one side of the top of the stepped base 1. A second wastewater treatment tank 3 is fixedly installed on the other side of the top of the stepped base 1, located on the first wastewater treatment tank 2. Several limiting blocks 4 are evenly fixedly installed on the inner walls of both sides of the second wastewater treatment tank 3. A preliminary filter cartridge 5 is movably installed inside the second wastewater treatment tank 3. A filter cartridge 4 is movably installed on the side of the second wastewater treatment tank 3 away from the preliminary filter cartridge 5. The precision filter element 6 has several positioning slots 7 at the bottom of the second sewage treatment tank 3. Several positioning rods 8 are evenly fixed at the bottom of the preliminary filter element 5 and the precision filter element 6. The positioning rods 8 are movably connected to the positioning slots 7. The operator only needs to lift the filter element upward to overcome the friction of the limiting block 4 and make the positioning rods 8 disengage from the positioning slots 7, so that the filter element can be easily removed. When replacing the new filter element, align the positioning rods 8 of the new filter element with the positioning slots 7 and then insert them downward until the filter element is locked and fixed by the limiting block 4.

[0023] The first sewage treatment tank 2 has a water inlet 9 at its top. Mounting seats 10 are fixedly installed on the inner walls of both sides of the first sewage treatment tank 2. A limiting drawer plate 11 is installed on one side of the first sewage treatment tank 2. A dust collection drawer box 12 is fixedly installed on the side of the limiting drawer plate 11 near the first sewage treatment tank 2. The dust collection drawer box 12 is movably connected to the top of the mounting seat 10. A filter screen 13 is fixedly installed at the bottom of the dust collection drawer box 12. A sealing groove 14 is provided on one side of the first sewage treatment tank 2 near the limiting drawer plate 11. The side of the limiting drawer plate 11 near the sealing groove 14 is fixed... A sealing ring 15 is installed, which corresponds to the sealing groove 14. A guide plate 16 is fixedly installed at the bottom of the first sewage treatment tank 2. A first drain pipe 17 is fixedly installed on the side of the first sewage treatment tank 2 near the second sewage treatment tank 3. The first drain pipe 17 extends into the interior of the first sewage treatment tank 2. A second drain pipe 18 is fixedly installed on the side of the second sewage treatment tank 3 away from the first sewage treatment tank 2. The wastewater first comes into contact with the filter screen 13 at the bottom of the dust collection drawer box 12. The filter screen 13 can intercept larger particles of impurities in the wastewater, playing a preliminary filtration role.

[0024] In this embodiment, a wastewater treatment filtration device with easily replaceable filter cartridges is used. First, wastewater flows into the device through the inlet 9 at the top of the first wastewater treatment tank 2. At this point, the wastewater first comes into contact with the filter screen 13 at the bottom of the dust collection drawer box 12. The filter screen 13 intercepts larger particles of impurities in the wastewater, providing initial filtration. Then, guided by the guide plate 16, the wastewater flows towards the side of the first wastewater treatment tank 2 closer to the second wastewater treatment tank 3, and enters the second wastewater treatment tank 3 through the first drain pipe 17. Inside the second wastewater treatment tank 3, wastewater first undergoes preliminary filtration through the primary filter element 5 to remove smaller particles and suspended solids. The pre-filtered wastewater continues to flow and then undergoes deep filtration through the precision filter element 6 to further purify the water. After treatment by these two stages of filters, the wastewater is effectively purified. The purified water is finally discharged through the second drain pipe 18 on the side of the second wastewater treatment tank 3 furthest from the first wastewater treatment tank 2. When it is necessary to replace the primary filter element 5 or the precision filter element 6, the positioning rod at the bottom of the filter element will automatically replace it. The positioning rod 8 is movably connected to the positioning slot 7 at the bottom of the second wastewater treatment tank 3. Simultaneously, the limiting blocks 4 on both sides inside the tank provide lateral restraint. The operator only needs to gently lift the filter element upwards to overcome the friction of the limiting blocks 4, allowing the positioning rod 8 to disengage from the positioning slot 7, thus easily removing the filter element. When replacing a new filter element, align the positioning rod 8 of the new filter element with the positioning slot 7, then insert it downwards until the filter element is secured by the limiting blocks 4, completing the quick replacement of the filter element. As wastewater treatment progresses, the filter screen 13 of the dust collection drawer box 12 will intercept a large amount of impurities. The wastewater needs to be cleaned regularly. Since the dust collection drawer box 12 is movably connected to the first wastewater treatment tank 2 through the mounting base 10, when cleaning, the operator only needs to pull the limit drawer plate 11 to pull the dust collection drawer box 12 out of the first wastewater treatment tank 2 to clean the impurities intercepted by the filter screen 13. After cleaning, the dust collection drawer box 12 is pushed back to its original position along the mounting base 10. At this time, the sealing ring 15 on the limit drawer plate 11 will fit tightly with the sealing groove 14 of the first wastewater treatment tank 2 to ensure the sealing of the device and prevent wastewater leakage.
