[0033] The extrusion roller degreasing device is installed on the sedimentation tank 1;

[0034] The extrusion roller degreasing device uses fiber oil-absorbing rings 5 ​​on the surface of the steel shaft 15 driven by the motor to absorb oil from the wastewater. The oil is then squeezed into the oil collection tank 7, which is located close to the fiber oil-absorbing rings 5 ​​and extends a certain distance. The absorbed oil is collected into the oil collection tank 7.

[0035] The sedimentation tank 1 is equipped with a sludge discharge port 9 and a wastewater inlet 10 at its lower part, both of which are fitted with valves 8. Both the sludge discharge port 9 and the wastewater inlet 10 can be made of exposed, threaded, seamless circular steel pipes, with valves 8 installed at the pipe openings. The valves 8 are sealing devices composed of metal materials and rubber gaskets. The adsorption purification tank 2 is equipped with adsorption filter plates 6 and a transverse water passage trough 14. A partition in the middle of the adsorption purification tank 2 divides it into front and rear spaces, both of which are equipped with adsorption filter plates 6. A transverse water passage trough 14 is located on one side of the partition. Figure 2 As shown, during the water filtration process, a loop-shaped waterway is formed between the front and rear spaces.

[0036] The drain outlet of the adsorption purification tank 2 is located at the top and connected to the water storage tank 3; the oil collection tank 7 is connected to the oil storage tank 4 through an oil delivery pipe. The lower part of the water storage tank 3 is provided with a drain outlet 11, which is equipped with a valve 8. The water storage tank 3 is also provided with an overflow outlet 13 and a suction outlet 12, with the suction outlet 12 covered by a prefabricated cover plate. The extrusion roller oil removal device includes a fiber oil-absorbing ring 5, an oil collection tank 7, and a steel shaft 15.

[0037] The steel shaft 15 is installed in the reserved hole of the sedimentation tank 1 using a bearing. The fiber oil-absorbing ring 5 is tightly connected to the surface of the steel shaft 15. One end of the steel shaft 15 is connected to the rotating shaft of the drive motor. The oil collection tank 7 is fixed to the sedimentation tank 1 using reserved bolts.

[0043] The working principle of this utility model is as follows: This utility model provides a centralized purification and treatment device for highway bridge deck drainage, which is installed in areas where highway bridge deck drainage is concentrated, the terrain is flat, and traffic is convenient.

[0044] The centralized purification and treatment unit mainly consists of a sedimentation tank 1, an adsorption purification tank 2, and a water storage tank 3, connected by drainage pipes. Wastewater is discharged to the sedimentation tank 1 for solid particle sedimentation and simultaneously passes through a squeeze roller oil removal device for oil pollution treatment. The treated wastewater is then discharged to the adsorption purification tank 2 for recirculation adsorption treatment of harmful substances, and finally discharged to the water storage tank 3 for water storage. The treated water can be pumped out for landscaping or discharged into the natural environment.

[0045] Specifically as follows:

[0046] Wastewater is discharged into sedimentation tank 1 for solid particle sedimentation. At the same time, the motor drives the connecting steel shaft 15 to rotate. The fiber oil-absorbing ring 5 on the surface of the connecting steel shaft 15 absorbs the oil in the wastewater. The oil is squeezed into the oil collection tank 7, which has a certain travel distance, and the oil is collected into the oil collection tank 7. The oil collection tank 7 collects the oil into the oil storage tank 4 through the oil pipeline. The wastewater that has been treated by solid particle sedimentation and oil treatment enters the adsorption purification tank 2 through the pipeline. The adsorption filter plate 6 and the transverse water passage trough 14 in the adsorption purification tank 2 further filter and treat the harmful substances in the wastewater and discharge it into the water storage tank 3.

[0047] The solid particles in sedimentation tank 1 need to be cleaned regularly. When cleaning, valve 8 needs to be opened to inject water into the sewage inlet 10, and at the same time, valve 8 needs to be opened to discharge the solid particles from the sewage outlet 9, so as to clean sedimentation tank 1.

[0048] The purified water in the reservoir 3 can be drawn out through the water inlet 12 for landscaping. When the water inlet 12 is not in use, it is covered with a prefabricated cover plate. When there is a large amount of purified water in the reservoir 3, it can be discharged through the overflow outlet 13 or the drainage outlet 11. The overflow outlet 13 can be used as an observation port for the water level of the reservoir 3.
