Technical Field
[0001] This utility model relates to the treatment and purification of wastewater, and is a membrane-driven series purification and wastewater recycling system that can efficiently and effectively treat and purify wastewater to high standards, and can also recycle and reuse sediments. Background Technology
[0002] The dramatic increase in domestic sewage and industrial wastewater has led to increasingly serious pollution of rivers and natural water bodies.
[0003] Currently, there is no single product on the market that can efficiently treat and purify domestic sewage and industrial wastewater, which prompted the research and development and application of this utility model. Utility Model Content
[0004] The purpose of this invention is to provide a membrane-driven wastewater purification and waste recycling system. The system involves first filtering the wastewater through a solid waste separation system to collect pollutants and solid waste. Then, the water is fed into a membrane-driven purification system and a biological cascade purification system for step-by-step treatment and purification, thereby treating and purifying the wastewater into qualified water for reuse or discharge.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] To achieve the above objectives, the membrane-driven wastewater series purification and wastewater recovery system of this utility model is characterized by: using a wheel-shaped recovery screen to separate and recover solid waste from the wastewater; using a sedimentation tank to recover sediment from the sedimentation tank; using a roller scraper to recover oil or solid waste from the filter membrane while it dynamically filters the wastewater; and using a biological cascade purification method to biologically purify the water after multiple filtrations by the filter membrane. The membrane-driven wastewater series purification and wastewater recovery system includes: a sludge-waste separation system 2, including a sludge-waste separation unit. The system includes a sedimentation tank; a membrane-driven purification system 3, comprising a membrane-driven wastewater purifier and a membrane-driven wastewater purification mechanism formed by connecting several membrane-driven wastewater purifiers in series; a filter membrane, including functional membranes and ordinary membranes, with continuous flexible magnetic strips on both sides of the filter membrane, wherein the functional membrane refers to a membrane that has the ability to pass through or adsorb specific objects; and a biological cascade purification system 4, comprising a wastewater biological purification device and a biological cascade purification system formed by connecting several wastewater biological purification devices in series, wherein the biological cascade purification system also includes a wastewater biological purification device, pollution-treating plants, and a pot stand. The system includes a wastewater harvesting vehicle and a wastewater treatment plant harvesting vehicle. The wastewater enters the wastewater separation system 2 for filtration, where solid waste is filtered and recovered. After wastewater separation, the wastewater enters a sedimentation tank within a sedimentation pond for settling, allowing the sediment to fall into the sedimentation tank for recycling. The wastewater, treated by the wastewater separation device and sedimentation tank in the wastewater separation system 2, then enters a membrane-driven purification system composed of several membrane-driven wastewater purifiers connected in series for further purification. After these two processes, the wastewater appears very clean and clear, but invisible ammonia nitrogen and other pollutants remain. Since certain components cannot be removed, in order to achieve higher discharge standards for the water, the water, after being treated and purified by the slag-waste separation system 2 and the membrane-driven purification system 3, enters the biological cascade purification system 4 for biological purification. Pollution-treating plants absorb and decompose components such as ammonia nitrogen in the water. In this way, after the cascade treatment and purification by the slag-waste separation system 2, the membrane-driven purification system 3, and the biological cascade purification system 4, the purification of the wastewater can reach a very high purification and discharge standard, thereby completing the high-standard treatment and purification of wastewater and fundamentally solving the problem of wastewater pollution to the environment.
[0007] The waste separation system 2 includes: a waste separation device, including: a waste pipe 1, a wheel-shaped recycling screen, a recycling tank 8, and a recycling vehicle 9, wherein the wheel-shaped recycling screen includes a wheel block 5, a wheel screen 6, and a motor 7, wherein the wheel screen 6 is equipped with a wheel basket 6A; a sedimentation tank, including a sedimentation tank 10 and a first sedimentation box 10A; the wastewater enters the wheel-shaped recycling screen from the waste pipe 1 for solid waste separation, so that the solid waste enters the wheel basket 6A, the motor 7 drives the wheel screen 6 to rotate, and the solid waste falls from the wheel basket 6A into the recycling tank 8 and then into the recycling vehicle 9 under the rotation of the wheel screen 6. The wastewater after solid waste separation enters the sedimentation tank 10 for sedimentation, and the sediment falls into the first sedimentation box 10A, thereby facilitating recycling and reuse. The wastewater after solid waste separation enters the secondary waste pipe 1A from the outlet pipe 10B.
[0008] The membrane-driven wastewater purifier includes: a water tank comprising a second sedimentation tank 11, a water storage tank 12, and a membrane plate, wherein the bottom of the second sedimentation tank 11 and the water storage tank 12 are respectively provided with a first wastewater recovery tank 11A and a second wastewater recovery tank 12A; the membrane plate includes a left membrane plate 12D and a right membrane plate 12E, and the two ends of the filter membrane 13 are respectively placed in the left membrane plate 12D and the right membrane plate 12E; the filter membrane includes the filter membrane 13 and a magnetic strip 13A, the magnetic strip 13A being attracted by its magnetic force.

[0009] The filter membrane 13 is placed between the left membrane tank plate 12D and the right membrane tank plate 12E via a membrane frame. The wastewater treated by the waste separation system 2 enters the second sedimentation tank 11 of the water tank. After being filtered by the filter membrane 13, the wastewater enters the water storage tank 12 for further sedimentation. The waste that cannot pass through the filter membrane 13 undergoes further sedimentation in the second sedimentation tank 11. The sedimented waste is then collected in the first waste recovery tank 11A. The drive mechanism pushes the filter membrane 13 to the scraper roller 13B, where the scraper on the scraper roller 13B scrapes the waste off the filter membrane, causing it to fall into the wastewater guide trough 12C for recovery. The membrane-driven mechanism pushes the filter membrane to the washing device for rinsing, opening the pores of the filter membrane that are blocked by dirt and waste, so that the filter membrane 13 can continue to perform efficient filtration. After rinsing, the filter membrane enters the water storage tank 12 under the push of the membrane-driven mechanism to perform a second filtration of the wastewater that has been filtered by the filter membrane for the first time, making the filtered water cleaner. The external power supply and the self-generated power supply are switched to provide a continuous power supply for the membrane-driven wastewater purifier. The control system controls the normal operation of the membrane-driven wastewater purifier under the control of the set program. The alarm device informs the first and second wastewater recovery tanks of the status of the sediment through the sensor.

Finally, it enters the greywater pipe 24 for reuse or discharge.

After two stages of treatment by the sludge-waste separation system 2 and the membrane-driven purification system 3, the wastewater enters the wastewater biological purification device through the third-stage wastewater pipe 1B for biological purification. After biological purification in the first inner basin 16, the second inner basin 16A, and the third inner basin 16B, the water enters the storage tank 18 through the water passage or gap 18B, and then enters the next wastewater biological purification device through the fourth-stage wastewater pipe 19 for the next biological purification, until it becomes reclaimed water or high-standard water with reuse value.
