[0002] The waste liquid filtration integrated device is a system specifically used for treating and filtering waste liquid. It realizes the effective purification and recycling of waste liquid by integrating various treatment technologies. The technical progress of the integrated sewage treatment device is manifested in aspects such as serving fewer people, occupying less land area, and having higher stability of the effluent water quality. With the rapid development of the electronics industry, the output of printed circuit boards has also increased year by year. In the etching process of manufacturing printed circuit boards, a large amount of alkaline etching liquid or acidic etching liquid is required. After these etching liquids are used up, etching waste liquid is formed. In the treatment of circuit board etching waste liquid, a pH adjustment liquid needs to be added to neutralize the pH value of the circuit board etching waste liquid: In a chemical waste liquid filtration device with Chinese patent application publication number CN 110639268 A, it includes a filtration tank and a filter. The filtration tank is provided with a water inlet pipe and a water outlet pipe. The filtration tank is also provided with a filtration box, which is arranged below the water outlet end of the water inlet pipe. The filtration tank is also provided with a baffle assembly.

[0028] Workflow and principle of the present invention: When in use, waste liquid to be processed can be filled into the first treatment tank 1 through the filling pipe 101. After precipitation, the first servo motor 105 controls the rotation of the threaded rod 1051 to drive the moving frame 110 to move downward, and at the same time, the pushing plate 109 moves upward to push the waste liquid inside the first treatment tank 1 upward. During this process, the waste materials precipitated in the waste liquid will be blocked at the bottom of the partition net 107 to filter large waste materials, enabling the waste liquid to rise through the partition net 107 to the second treatment tank 103. At the same time, the moving frame 110 moves to the bottom of the second treatment tank 103. At this time, the bottom of the collecting member 111 will contact the top of the fixing member 108, thereby pushing the collecting member 111 upward, causing the collecting holes 1118 inside the collecting member 111 to move to the top of the moving frame 110. At this time, the waste liquid will flow into the collecting member 111 through the collecting holes 1118. Then, the threaded rod 1051 rotates in the reverse direction to make the moving frame 110 move upward. During the process, the collecting member 111 is pushed back by the support spring 1113 to collect and convey the filtered waste liquid to the top of the conveying pipe 104. The air pump 301 can be used to extract the air inside the three-way pipe 2. Since the liquid storage tank 4 at the bottom of the three-way pipe 2 is in a sealed state, when pumping air, the sealing member 1117 inside the moving frame 110 can be pulled to one side, so that the liquid inside the collecting member 111 can be pumped into the three-way pipe 2 through the first communication hole 1103 and the second communication hole 1115, enabling the liquid to quickly pass through the filter screen inside the mounting frame 201 to filter the fine particle waste materials in the liquid. The filtered liquid flows to one side of the hydrophobic breathable membrane 203 through the first one-way valve 202. The liquid will be blocked by the hydrophobic breathable membrane 203 and then fall into the liquid storage tank 4 through the three-way pipe 2. The space inside the liquid storage tank 4 can be separated by the partition plate 407, enabling the liquid inside the three-way pipe 2 to directly flow to the bottom of the partition plate 407. The water pump 4032 can be protected by the water isolation frame 4031. The water pump 4032 can convey the pH value adjusting medicament inside the storage tank 403 to the top of the partition plate 407 through the connecting pipe 4033 and the communicating pipe 402, enabling the medicament to flow into the flow channel 4084 through the liquid inlet 4083 and then be injected into the liquid inside the liquid storage tank 4 through the second one-way valve 4086 inside the communicating groove 4085 of the stirring member 4082, so that the medicament can be better mixed with the liquid in the liquid storage tank 4. The detector 409 can be used to detect the pH value of the liquid in the liquid storage tank 4. The second servo motor 401 can be used to control the rotation of the rotating rod 408, thereby driving the stirring member 4082 to stir the liquid inside the liquid storage tank 4, making the pH value adjusting medicament and the liquid in the liquid storage tank 4 mix more evenly. Through the gear member 4081 and the gear ring 410, when the rotating rod 408 rotates, it can drive the gear member 4081 to rotate. By the rotation of the gear member 4081, the gear ring 410 can be driven to rotate, thereby driving all the rotating rods 408 to rotate simultaneously.
