[0002] In the process of modern construction, with the improvement of environmental awareness and increasingly stringent laws and regulations, the sewage generated at the construction site must be effectively treated before it can be discharged to reduce the impact on the environment. As one of the key facilities to achieve this goal, the importance of sewage treatment equipment for construction sites is self-evident.

[0003] Existing construction site sewage treatment equipment mainly removes some suspended matter by introducing sewage into one or more sedimentation tanks, using gravity to make larger particles settle to the bottom of the tank to form a sludge layer. Although this method can remove impurities to a certain extent, long-term operation will cause a large amount of sludge to accumulate at the bottom of the sedimentation tank, occupying valuable storage space and possibly interfering with subsequent treatment processes. What's more serious is that when the sludge needs to be removed, the entire sewage treatment system must be stopped, which will have a negative impact on the construction progress and increase the time and cost of the project. In addition, the geographical location and working conditions of construction sites change frequently, and most of the existing construction site sewage treatment devices are difficult to quickly move from one location to another due to their complex structure and large size.

The right side of the third treatment tank 5 A fixed frame 15 is connected to the upper part, and an ultraviolet lamp 16 is installed on the upper inner part of the fixed frame 15. A water inlet pipe 17 is connected to the left upper part of the first treatment pool 3, and the rear end of the water inlet pipe 17 is located inside the first treatment pool 3. A first connecting pipe 18 is connected between the upper front part of the first treatment pool 3 and the upper left part of the second treatment pool 4.

[0030] like Figure 5 and Figure 6 As shown, the cleaning component includes a collecting frame 22, a drain pipe 23 and a screw feeder 24. The collecting frame 22 is connected between the top rear sides of the first treatment tank 3, the second treatment tank 4 and the third treatment tank 5. The collecting frame 22 is inclined to adapt to the curvature of the inner wall of the rotating filter cartridge 6, and the collecting frame 22 passes through the upper rear part of the inner side of the three rotating filter cartridges 6. The drain pipe 23 is connected to the left side of the collecting frame 22 and is connected. The drain pipe 23 is T-shaped. A screw feeder 24 is installed on the drain pipe 23, and the screw rod of the screw feeder 24 passes through the inside of the drain pipe 23 and the inside of the collecting frame 22.

[0031] Initially, a proper amount of filler is placed between each two adjacent filter plates 13, and a proper amount of activated carbon is installed on the inner wall of the fixed filter cartridge 14; first, the semi-trailer body 1 is towed by the semi-trailer head to move to the designated position, and then the water inlet pipe 17 can be connected with the sewage pipe, so that the sewage pipe can discharge the sewage mixed with flocculant into the water inlet pipe 17, and the sewage in the water inlet pipe 17 will continue to enter the first treatment tank 3, so that the sewage can be precipitated in the first treatment tank 3, thereby completing the first treatment of the sewage; as the sewage in the first treatment tank 3 increases, the liquid level in the first treatment tank 3 will gradually rise, and this At this time, the impurities in the first treatment tank 3 will be precipitated in the rotating filter cartridge 6 on the left, and the clean water in the first treatment tank 3 will enter the second treatment tank 4 through the first connecting pipe 18. As the clean water in the second treatment tank 4 increases, the liquid level in the second treatment tank 4 will gradually rise. At this time, the clean water in the second treatment tank 4 will gradually pass through the circular hole 1201, the filter plate 13 and the filler, while the fine impurities in the second treatment tank 4 cannot pass through the circular hole 1201, so that the fine impurities in the second treatment tank 4 will be precipitated in the rotating filter cartridge 6 in the middle, and the microorganisms in the clean water will gradually adhere to the surface of these fillers and begin to The microorganisms in the biofilm can capture and decompose organic matter and other biodegradable substances in the clean water, thereby completing the second treatment of the sewage. Subsequently, the clean water after the secondary treatment will flow into the third treatment tank 5 through the square groove 19. As the clean water in the third treatment tank 5 increases, the liquid level in the third treatment tank 5 will gradually rise. At this time, the clean water in the third treatment tank 5 will pass through the fixed filter cartridge 14 and the activated carbon inside it, while the fine impurities in the third treatment tank 5 cannot pass through the filter holes of the fixed filter cartridge 14, so that the fine impurities in the third treatment tank 5 will The activated carbon can remove organic matter, color, taste, odor and some inorganic matter in the water, thereby completing the third treatment of the sewage; then, the clean water after the three treatments will enter the fixed frame 15 through the second connecting pipe 20, and the controller 2 can control the ultraviolet lamp 16 to start working. The ultraviolet lamp 16 can sterilize the clean water flowing through the fixed frame 15 with ultraviolet light, thereby completing the fourth treatment of the sewage; the clean water after the four treatments will be discharged through the outlet pipe 21 for subsequent use in other places, so as to achieve the purpose of water recycling;In the process of treating sewage, the sewage recycling equipment can control the driving motor 11 through the controller 2 to drive the rotating rod 9 to rotate, and the rotating rod 9 can drive the rotating filter cartridge 6 to rotate through the meshing action of the driving gear 10 and the tooth hole 601, and the rotating filter cartridge 6 can drive the fixed inclined plate 7 to rotate, and the fixed inclined plate 7 can drive the impurities deposited in the rotating filter cartridge 6 to rotate from bottom to top. Since the fixed inclined plate 7 is in an inclined state, the impurities on the fixed inclined plate 7 will not fall down into the first treatment tank 3, the second treatment tank 4 and the third treatment tank 5 until the fixed inclined plate 7 rotates to the collection frame 2. 2, the impurities on the fixed inclined plate 7 will fall down into the collection frame 22 due to gravity. At this time, the screw feeder 24 can be controlled by the controller 2 to start working. The screw feeder 24 can transport the impurities in the collection frame 22 to the left to the sewage pipe 23, and discharge them downward through the sewage pipe 23, which is convenient for manual unified treatment. In this way, there is no need to manually regularly treat the impurities in the first treatment tank 3, the second treatment tank 4 and the third treatment tank 5, and there is no need to shut down the sewage recycling equipment, so that the sewage recycling equipment can continuously treat the sewage and improve work efficiency. ;

[0033] During the sewage treatment process of the sewage recycling equipment, the blower 28 can be controlled by the controller 2 to start working. The blower 28 can blow air into the hollow tube 26 through the air supply pipe 29. The wind in the hollow tube 26 will be blown forward and downward through the strip holes 2601 and the air outlet frame 27 in turn. When the fixed inclined plate 7 rotates to above the collecting frame 22, the wind blown out from the front end of the air outlet frame 27 can pass through the filter holes on the rotating filter cartridge 6 to blow the impurities on the fixed inclined plate 7 into the collecting frame 22, thereby assisting the discharge of impurities and preventing the filter holes on the rotating filter cartridge 6 from being blocked due to the accumulation of impurities.

The pressure plate 38 is located inside the connecting frame 30. The height of the pressure plate 38 is consistent with the spacing between the first connecting plate 34 and the second connecting plate 36. The right side of the top and the right side of the bottom of the pressure plate 38 are chamfered. The right side of the pressure plate 38 contacts the left side of the filter bag 32. The reflux component is used to transport the water squeezed out of the sludge after being compressed to the first treatment tank 3, and the mud discharge component is used to discharge the compressed sludge; the reflux component includes a water pump 39, a water pump pipe 40 and a drainage pipe 41. The water pump 39 is installed on the front side of the water collecting frame 31. The water inlet of the water pump 39 is connected to the water pump pipe 40. The lower end of the water pump pipe 40 passes through the collecting At the lower front part of the water frame 31, both ends of the drain pipe 41 are connected to the water inlet pipe 17 and the water outlet of the water pump 39 respectively; the mud discharge assembly includes a guide plate 42, a rotating inclined plate 43, a servo motor 44 and a limit plate 45.

At the same time, the controller 2 will control the water pump 39 to extract the water in the water collecting frame 31 through the water pumping pipe 40, and through The drain pipe 41 transports water to the water inlet pipe 17 so that the water squeezed out of the impurities can be reprocessed and utilized, saving water resources; then the hydraulic cylinder 37 can be controlled by the controller 2 to drive the pressure plate 38 to move to the left and reset to separate from the filter bag 32, and at the same time, the servo motor 44 can be controlled by the controller 2 to drive the rotating inclined plate 43 to reverse and reset, so that the right end of the rotating inclined plate 43 contacts the left end of the guide plate 42 again, and at the same time, the second electric push rod 35 can be controlled by the controller 2 to drive the second connecting plate 36 to move to the left and reset, and the second connecting plate 36 can drive the left side of the lower edge of the filter bag 32 to move to the left and reset, so as to open the lower end of the filter bag 32, at this time, the impurities squeezed out of the water in the lower half of the filter bag 32 will fall down to the guide plate 42 and the top of the rotating inclined plate 43, and slide to the left along the guide plate 42 and the top of the rotating inclined plate 43 for manual unified collection. Then, the servo motor 44 can be controlled by the controller 2 to drive the rotating inclined plate 43 to rotate, so that the right end of the rotating inclined plate 43 is separated from the left end of the guide plate 42. At the same time, the second electric push rod 35 can be controlled by the controller 2 to drive the second connecting plate 36 to move rightward, so that the lower end of the filter bag 32 is re-sealed. Then, the first electric push rod 33 can be controlled by the controller 2 to drive the first connecting plate 34 to move to the left and reset, so that the middle part of the filter bag 32 is opened. At this time, the impurities temporarily stored in the upper part of the filter bag 32 will fall down into the lower part of the filter bag 32. Repeat the above operation to dehydrate the impurities again.
