Description

Technical Field

[0001] This utility model relates to the technical field of integrated wastewater purification device structure, and in particular to an integrated purification device for high-concentration phosphorus-containing wastewater. Background Technology

[0002] Integrated wastewater purification devices are highly efficient and automated water treatment equipment widely used in industrial wastewater treatment, domestic sewage treatment, and water source purification. These devices typically combine multiple treatment technologies, such as chemical precipitation and biological treatment, to effectively remove pollutants from wastewater. Chemical precipitation involves adding chemical agents to wastewater to react with pollutants and form insoluble precipitates, which are then removed from the wastewater through solid-liquid separation. Biological treatment utilizes the characteristics of microbial communities to release phosphorus under anaerobic conditions and absorb excess phosphorus under aerobic conditions, thereby removing phosphorus from wastewater.

[0003] The structure of an integrated wastewater purification device typically includes multiple functional units, such as a reaction tank, a flocculation tank, a sedimentation tank, a sludge removal system, and possibly a bioreactor. In existing technologies, the upper surfaces of the sedimentation tank, aerobic tank, anoxic tank, and anaerobic tank in an integrated wastewater purification device are sealed and fixed. During maintenance, bolts need to be removed to access the interior of the sedimentation tank, aerobic tank, anoxic tank, and anaerobic tank. This method has a problem: it requires frequent tightening and loosening of bolts and opening and closing of the inlets of the sedimentation tank, aerobic tank, anoxic tank, and anaerobic tank, making maintenance inconvenient and labor-intensive.

A movable door 8 is movably installed on the front edge of the control room 1 via a hinge. An air inlet pipe 9 is fixedly connected between the control room 1, the aerobic tank 3, and the anoxic tank 4. A first return pipe 10 is fixedly connected to the anoxic tank 4, and a second return pipe 11 is fixedly connected to the aerobic tank 3 and the anoxic tank 4. A flange interface 12 is fixedly installed on the rear surface of the anaerobic tank 5 near one corner. The electric lifting cover 6, together with the ladder 7, makes it easier and more labor-saving to enter the interior of the sedimentation tank 2, aerobic tank 3, anoxic tank 4 and anaerobic tank 5 for inspection and maintenance. This is conducive to the long-term normal operation of the integrated purification device for high-concentration phosphorus-containing wastewater. The electric lifting cover 6 can automatically lift and lower, and can automatically open and close the entrances of the sedimentation tank 2, aerobic tank 3, anoxic tank 4 and anaerobic tank 5. The ladder 7 makes it easier for staff to climb into the interior of the sedimentation tank 2, aerobic tank 3, anoxic tank 4 and anaerobic tank 5.

[0023] In this embodiment, the electric lifting cover 6 includes a rectangular cover plate 601, a first frame 602, a second frame 603, a third frame 604, a fourth frame 605, a reinforcing frame 606, a first rubber frame 607, a second rubber frame 608, a third rubber frame 609, a fourth rubber frame 610, a motor outer frame 611, an electric motor 612, a screw 613, and a threaded sleeve 614.

[0024] In this embodiment, frame 602 is fixedly installed on the lower surface of rectangular cover 601 near one end, frame 603 is fixedly installed on the lower surface of rectangular cover 601 near frame 602, frame 604 is fixedly installed on the lower surface of rectangular cover 601 near frame 603, and frame 605 is fixedly installed on the lower surface of rectangular cover 601 near the other end. Reinforcing frame 606 is fixedly installed on the upper surface of rectangular cover 601. Frames 602, 603, 604, and 605 enable rectangular cover 601 to better cover sedimentation tank 2, aerobic tank 3, anoxic tank 4, and anaerobic tank 5.
