[0006] Preferably, the filter fixing member includes a threaded bolt, a limit plate, a spring and a threaded cap column rotatably connected to the connecting frame, one end of the spring is fixedly connected to the inner end of the limit groove, and the other end is fixedly connected to the limit plate, the threaded cap column is fixedly connected to the limit plate and threadedly connected to the threaded bolt.

[0007] Preferably, the other end of the movable connecting plate is rotatably mounted on the upper end of the second filter screen.

[0008] Preferably, the bottom end of the wastewater treatment tank body is inclined, and an outlet pipe is provided at the inclined bottom.

[0009] Preferably, the first filter screen, the second filter screen and the connecting frame are all made of stainless steel.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] This easily replaceable filter screen for industrial wastewater treatment pools is installed in the connecting frame by sliding the filter screen, and is connected to the positioning slide groove and the connecting frame on the side of the wastewater treatment pool body by a threaded rod. When the filter screen is blocked or damaged, there is no need to stop the equipment and disassemble the entire equipment. Only the threaded rod needs to be rotated to pull out the connecting frame and the filter screen inside, and the equipment can be easily cleaned or replaced, which reduces the workload and downtime of maintenance personnel, reduces labor costs, improves the continuity and efficiency of wastewater treatment, and also reduces the risk of corrosion to other parts of the equipment.
