Description

Technical Field

[0001] This invention relates to the field of wastewater purification and treatment, and is a reverse osmosis wastewater purification and reuse system. Background Technology

[0002] Every household in the city discharges domestic sewage every day. In residential communities, sewage from residents' homes is discharged underground through the building's sewer pipes and eventually flows into the municipal drainage network. However, this domestic sewage cannot be discharged directly from residents' homes into the municipal drainage network. Generally, multiple sewage collection wells are first built underground in the community, and then the sewage is discharged into the municipal drainage network through these collection wells.

[0003] However, in actual use, sewage often contains large garbage and oil stains that are difficult to separate and clean in the well chamber. Traditional well chambers have poor sealing, low strength and are easily deformed. Sewage is not recycled and drainage is not timely during the rainy season. Therefore, improving and perfecting the above-mentioned problems has become an urgent issue to be addressed. Summary of the Invention

[0004] This invention provides a reverse osmosis wastewater purification and reuse system that overcomes the shortcomings of existing technologies. It provides a one-piece plastic tank that can separate oil stains and large garbage, while also having good corrosion and rust prevention, good sealing performance, high overall strength, recycling of some wastewater, and timely drainage.

[0005] A reverse osmosis wastewater purification and reuse system includes a main well, external reinforcing ribs, overflow pipe, drainage pipe, auxiliary well, ventilation inspection pipe, water collection pipe, lifting pump well shaft, ventilation inspection well, lifting lugs, wastewater inlet pipe, outlet, oil sludge cleaning platform, oil separator filter plate, baffle grating, internal reinforcing ribs, sewage discharge hose, ladder, orifices, wastewater lifting pump, one-way valve, pumping hose, metal ribs, sewage outlet, and automatic dosing equipment; characterized in that the main well has two external reinforcing ribs arranged on four sides of its transverse waistline. Two external reinforcing ribs are located at one-third of each of the four sides. A sewage inlet pipe is located in the middle of the upper third on the left side of the main shaft, and the sewage inlet pipe is connected to the inside of the main shaft. A hoisting pump shaft and a ventilation inspection shaft are located in the upper part of the main shaft, and their interiors are connected to the main shaft. The ventilation inspection shaft is located in the center of the upper part of the main shaft, and the hoisting pump shaft is located to the right of the ventilation inspection shaft. Four hoisting lugs are set on the four edges of the upper part of the main shaft. A drain pipe is set on the right side of the hoisting pump shaft. A drain pipe is set on the upper right side of the hoisting pump shaft. An overflow pipe is set on the top right side of the hoisting pump shaft inside the main shaft. A water collection pipe is connected to the top right side of the hoisting pump shaft, and the water collection pipe leads to the auxiliary shaft. A ventilation inspection pipe and an automatic dosing device are set on the top of the auxiliary shaft. A water outlet is set on the upper right side of the auxiliary shaft. The hoisting pump shaft inside the main shaft has holes in its pipe body. A sewage lift pump is set at the bottom of the hoisting pump shaft. The sewage lift pump is connected to a sewage discharge hose and a water pumping hose. The drainage pipe enters from inside the hoisting pump well and finally connects to the municipal pipe network. The water pumping hose enters from inside the hoisting pump well and finally connects to the auxiliary well. The ventilation inspection well has holes on the left and right sides inside the main well. The ventilation inspection well has a complete pipe body at the bottom and top 10cm inside the main well, and the bottom is fixedly connected to the oil sludge cleaning platform. The main well has a vertical baffle grid on the left side of the hoisting pump well. The oil sludge cleaning platform has an oil separator filter plate at the bottom. The inner wall of the main well has internal reinforcing ribs on all six sides.

[0006] Preferably, the main shaft, the hoisting pump shaft, and the ventilation inspection shaft are all made of plastic.

[0007] Preferably, the lifting lugs are provided with lifting holes.

[0008] Preferably, the oil separator filter plate has holes, and the baffle grille has holes.

[0009] Preferably, a sewage outlet is provided at the lower right side of the auxiliary well.

[0010] Preferably, the top of the hoisting pump well and the ventilation inspection well are each equipped with a well cover.

[0011] Preferably, the outer and inner reinforcing ribs have a plastic outer cross-section and are wrapped with a metal rib.

[0012] Preferably, an overflow check valve is provided at the leftmost outlet of the overflow pipe.

[0013] Preferably, the ladder and the inner wall of the ventilation inspection well are fixedly connected.

[0014] Preferably, the auxiliary well is equipped with an air flotation machine.

[0015] This invention features a reasonable and compact structure. In use, domestic sewage enters the upper left part of the main well through the sewage inlet pipe. Oil clumps and large debris in the sewage are separated by an oil-water separator. The sewage then flows through holes in the oil-water separator into the lower left part of the main well. Sewage also flows to the right through holes in the baffle grille and enters the pipe through holes in the lifting pump shaft. When the secondary well needs water storage, the sewage lifting pump pumps water through a pumping hose into the secondary well. Chemical purification solutions (PAC, PAM, etc.) can then be added to the secondary well via an automatic dosing device to cultivate microorganisms that digest and purify the small particles in the purified water. This process removes odors and meets national environmental protection standards for wastewater reuse. The treated water can then be used to irrigate plants and trees, aligning with the new concepts of energy conservation, water conservation, and sustainable development. After the sewage in the auxiliary manhole is purified, the purified water from the upper part is released from the outlet for use in the community's landscaping, achieving the purpose of sewage reuse. Impurities and wastewater at the bottom of the purified auxiliary manhole are periodically discharged through the drain outlet. Unnecessary sewage is pumped through a sewage lift pump and discharged through a drain hose to the outside of the main manhole into the municipal drainage network. During the rainy season, if the drain pipe is not draining in time, sewage will flow through the overflow check valve into the overflow pipe and then into the municipal drainage network. Maintenance personnel periodically enter the main manhole through a ladder in the ventilation inspection well and stand on the grease trap to clean the grease filter. Oil and debris on the slab are cleaned to the outside of the main well. The main well is buried below ground level, while the auxiliary well is buried above ground level. The inner and outer reinforcing ribs can strengthen the main well. At the same time, the internal metal ribs of the reinforcing ribs can enhance their strength. The plastic layer wrapped around the reinforcing ribs can effectively prevent corrosion and rust. Most of the materials in the entire system are plastic, which can effectively prevent corrosion and rust and has good sealing performance. This effectively solves the problems of existing technologies, such as large garbage and oil stains in the sewage being difficult to separate and clean in the well chamber, poor well chamber sealing, low strength and easy deformation, lack of sewage recycling, and untimely drainage during the rainy season.

The main well 1 has two external reinforcing ribs 2 arranged on the four sides of its outer surface, with each rib 2 located at one-third of its length. A sewage inlet pipe 11 is located in the middle of the upper third of the left side of the main well 1, and the sewage inlet pipe 11 communicates with the interior of the main well 1. A hoisting pump well 8 and a ventilation inspection well 9 are located on the upper part of the main well 1, both communicating with the main well 1. The ventilation inspection well 9 is located at the center of the upper part of the main well 1, and the hoisting pump well 8 is located to the right of the ventilation inspection well 9. Four hoisting lugs 10 are respectively provided on the four edges of the upper part of the main well 1. A hoisting pump well 8 is located on the right side of the hoisting pump well 8. A drain pipe 4 is installed on the upper right side of the hoisting pump well shaft 8. An overflow pipe 3 is installed on the top right side of the section of the hoisting pump well shaft 8 inside the main well 1. A water collection pipe 7 is connected to the top right side of the hoisting pump well shaft 8, and the water collection pipe 7 leads to the auxiliary well 5. A ventilation inspection pipe 6 and an automatic dosing device 25 are installed on the top of the auxiliary well 5. A water outlet 12 is installed on the upper right side of the auxiliary well 5. An eyelet 19 is provided on the pipe body of the hoisting pump well shaft 8 inside the main well 1. A sewage lift pump 20 is installed at the bottom inside the hoisting pump well shaft 8. The sewage lift pump 20 is connected to a sewage discharge hose 17 and a water pumping hose. 22. The sewage hose 17 enters the drainage pipe 4 from inside the hoisting pump well 8 and finally connects to the municipal pipe network. The water pumping hose 22 enters the water collection pipe 7 from inside the hoisting pump well 8 and finally connects to the auxiliary well 5.

The inner wall of the main well 1 has internal reinforcing ribs 16 on all six sides.

[0029] Working Principle: During operation, domestic sewage enters the upper left part of the main well 1 through the sewage inlet pipe 11. Oil lumps and large debris in the sewage are separated by the oil-water separator 14. The sewage flows into the lower left part of the main well 1 through the holes in the oil-water separator 14, and flows to the right through the holes in the baffle grating 15. It then enters the pipe through the holes 19 on the lifting pump well 8. When the auxiliary well 5 needs to store water, the sewage lifting pump 20 pumps the sewage and water into the auxiliary well 5 through the pumping hose 22. Then, chemical purification chemicals (PAC, PAM, etc.) can be added to the auxiliary well 5 through the automatic dosing device 25 to cultivate microorganisms. These microorganisms digest and purify the small particles in the purified water. The odor is removed, meeting the national environmental protection standards for wastewater reuse. After meeting the standards, the water can be used to irrigate flowers, trees, and shrubs, which is in line with the new concept of promoting energy conservation, water conservation, and sustainable development. After the sewage in the auxiliary well 5 is purified, the purified water from the upper part of its interior is released from the outlet 12 for use in the greening of plants in the community, achieving the purpose of sewage reuse. After purification, the impurities and wastewater at the bottom of the auxiliary well 5 are periodically discharged through the sewage outlet 24. Unnecessary sewage is discharged through the sewage lift pump 20 and the sewage hose 17 to the outside of the main well 1 and enter the municipal drainage network. If the sewage pipe is not drained in time during the rainy season, the sewage will flow into the overflow pipe 3 through the overflow check valve 21 and then into the municipal drainage network. Maintenance personnel regularly enter the main well 1 through the ladder 18 in the ventilation inspection well 9 and stand on the oil sludge cleaning platform 13. The oil and debris on the oil-water separator 14 are cleaned to the outside of the main well 1. The main well 1 is buried below the ground level, and the auxiliary well 5 is buried above the ground level. The inner and outer reinforcing ribs can strengthen the main well 1. At the same time, the metal ribs 23 wrapped inside the reinforcing ribs can enhance the strength of the reinforcing ribs. The plastic layer wrapped outside the reinforcing ribs can effectively prevent corrosion and rust. Most of the materials in the entire system are plastic, which can effectively prevent corrosion and rust and has good sealing performance. It effectively solves the problems of existing technologies, such as large garbage and oil stains in the sewage, which are not easy to separate and clean in the well chamber, poor well chamber sealing, low strength and easy deformation, sewage not being recycled, and untimely drainage during the rainy season.
