Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more specifically, it relates to a method for recycling and treating environmentally friendly wastewater in building construction. Background Art

[0002] The construction water used at the construction site includes: construction production water, construction machinery water, on-site construction living water, domestic water, fire fighting water, etc. At present, the construction water generally comes from tap water, and the utilization rate of construction wastewater, domestic wastewater and rainwater on the construction site is relatively low, resulting in waste of water resources.

[0003] The Chinese patent application document with the publication number CN113502874A discloses a non-traditional wastewater recycling and circulating spray dust suppression construction method for buildings. This non-traditional wastewater recycling and circulating spray dust suppression construction method for buildings includes the following steps: Step 1, arranging a reservoir, a diversion ditch and a drainage pipeline network: Select a location on the construction site to build a reservoir; and set a diversion ditch more than 2m away from the four sides of the building, and the diversion ditch is communicated with the reservoir, and rainwater flows into the reservoir through the diversion ditch; lay a drainage pipe, and the drainage pipe is connected to the construction production wastewater drainage pipe, and the construction production wastewater is introduced into the reservoir through the drainage pipe; Step 2, installing a water pump and a filtering device: Set up a filtering device room, which is used to place the water pump and the filtering device. One end of the water pump is connected to the reservoir, and the other end is connected to the filtering device to pump the water in the reservoir into the filtering device for filtering, and the recycled water after filtering flows out from the water outlet node of the filtering device; and then the recycled wastewater is used for spray dust suppression.

[0004] However, since this non-traditional wastewater recycling and circulating spray dust suppression construction method for buildings only filters and treats the wastewater through a filtering device, and the filtering device is composed of a sand filter, a carbon filter, a water softener and a precision filter connected in sequence. However, due to the large amount of particulate impurities in the wastewater, after passing through the sand filter, the carbon filter, the water softener and the precision filter in sequence, it will cause rapid accumulation of particles inside the sand filter, the carbon filter, the water softener and the precision filter, which will affect the sustainable recycling and treatment of the wastewater, and further affect the treatment effect and efficiency of the wastewater, and there is room for improvement. Summary of the Invention

[0005] Aiming at the deficiencies existing in the prior art, the purpose of the present invention is to provide a method for recycling and treating environmentally friendly wastewater in building construction, and this method for recycling and treating environmentally friendly wastewater in building construction has the effect of significantly improving the efficiency of wastewater recycling and treatment.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A method for recycling and treating environmentally friendly wastewater in building construction, including the following steps:

[0008] Step 1: Arrange a primary filtration water storage tank, and guide the construction wastewater into the water storage tank A, and enter the water storage tank B above through the water storage tank screen at the lower end of the water storage tank A to form primary filtration environmental wastewater;

[0009] Step 2, the primary filtered environmental wastewater in the reservoir B is introduced into the filter press chamber through the inclined downpipe, and after filter press, it enters the fine filter chamber through the filter press screen to form filter press environmental wastewater;

[0010] Step 3: Pass the filtered environmentally friendly wastewater in the fine filtration chamber through the fine filtration screen into the recovery treatment pool to obtain fine filtration treated environmentally friendly water.

[0011] By adopting the above technical scheme, when construction wastewater passes through the primary filtration water storage tank, impurities exceeding the set size are precipitated on the lower side of the water storage tank screen, and the primary filtered environmentally friendly wastewater is formed in the water storage tank B and then filtered through the filter press screen and the fine filter screen to achieve the recycling of construction wastewater, so that the method for recycling and treating environmentally friendly construction wastewater has the effect of significantly improving the efficiency of wastewater recycling and treatment.

[0012] The present invention is further configured as follows: two inclined dividing cavity plates are arranged in the primary filtration water reservoir, which are respectively located at the two ends of the water reservoir partition net; the dividing cavity plates and the water reservoir partition net are used to divide the primary filtration water reservoir into water reservoir A and water reservoir B located at the two ends, and the water reservoir partition net is arranged horizontally.

[0013] By adopting the above technical scheme, the inclined dividing cavity plate and the water tank partition net divide the water tank A and water tank B in the primary filtration water tank, while the horizontally arranged water tank partition net effectively filters the impurities in the construction wastewater, and when the construction wastewater passes through the water tank partition net upward, the impurities attached to the water tank partition net fall under the action of their own gravity, thereby effectively avoiding the accumulation of impurities on the water tank partition net and affecting the recovery and treatment efficiency of the construction wastewater, so that the environmentally friendly construction wastewater recycling and treatment method has the effect of significantly improving the wastewater recycling and treatment efficiency.

[0014] The present invention is further configured as follows: a feed chamber A and a filter press chamber B are provided in the filter press chamber, the inclined downpipe is connected to one end of the feed chamber A away from the filter press chamber B, the filter press screen is fixed at the end away from the feed chamber A, and a filter press plate which reciprocates toward and away from the filter press screen is provided in the filter press chamber B, the length and width of the filter press plate respectively match the corresponding length and width of the filter press chamber B, the filter press plate is connected to a driving mechanism for driving the movement, and the driving mechanism is connected to a long scraper for removing attachments on the surface of the filter press screen.

[0015] By adopting the above technical solution, after the initially filtered environmental protection wastewater enters the feeding chamber A, it automatically flows into the pressure filtration chamber B. When the pressure filtration plate moves towards the pressure filtration partition net, the initially filtered environmental protection wastewater in the pressure filtration chamber B will be squeezed towards the pressure filtration partition net, enabling the initially filtered environmental protection wastewater to quickly pass through the pressure filtration partition net. At the same time, impurities will adhere to the pressure filtration partition net while the pressure filtration partition net filters the initially filtered environmental protection wastewater. Furthermore, the driving mechanism will drive the long strip-shaped scraper to remove the impurities adhering to the pressure filtration partition net, effectively preventing impurities from accumulating on the pressure filtration partition net and affecting the recycling efficiency of construction wastewater. As a result, this method for recycling construction environmental protection wastewater has the effect of significantly improving the wastewater recycling efficiency.

[0016] The present invention is further configured as follows: The driving mechanism includes a driving motor fixed on the outer side wall of the pressure filtration chamber. The output shaft of the driving motor extends into the pressure filtration chamber and is connected to a driving turntable. The driving turntable is provided with an eccentric column.

The end of the pushing pressure filtration rod away from the eccentric column is rotatably connected to the pressure filtration plate up and down. The transmission connection unit is used to drive the long strip-shaped scraper to perform a reciprocating lifting movement in the vertical direction.

[0017] By adopting the above technical solution, when the driving motor operates, it will drive the driving turntable to perform a circumferential rotational movement around the output shaft through the output shaft. Furthermore, the transmission connection unit and the pushing pressure filtration rod rotatably connected to the eccentric column will perform corresponding movements, so as to achieve the purpose of making the pushing pressure filtration rod push and pull the pressure filtration plate and the transmission connection unit drive the long strip-shaped scraper to perform a reciprocating lifting movement in the vertical direction, thereby significantly improving the recycling efficiency and effect of construction wastewater.

[0018] The present invention is further configured as follows: A limiting transverse groove matching the moving direction of the pressure filtration plate is provided in the pressure filtration chamber.

[0020] The present invention is further configured as follows: At the lower side of one end of the pressure filtration chamber B close to the feeding chamber A, an inclined guide bottom plate is provided, and at the upper side, a high platform top wall is provided; A gap for sediment to pass through is formed between the inclined guide bottom plate and the lower end of the pressure filtration plate; A gap for gas to enter and exit is formed between the high platform top wall and the upper end of the pressure filtration plate.

[0021] By adopting the above technical scheme, when the filter press plate is pulled and moved to the inclined guide bottom plate by pushing the filter press rod, a gap for the sediment to pass through will be formed between the inclined guide bottom plate and the lower end of the filter press plate, and when the impurity sediment is driven to move to one side of the inclined guide bottom plate in combination with the movement of the filter press plate, the impurity sediment moves to the feed A chamber under the guidance of the inclined guide bottom plate, thereby effectively avoiding the accumulation of impurity sediment in the filter press B chamber and affecting the treatment efficiency and effect of the primary filtration environmental wastewater, and making the construction environmental wastewater recycling treatment method have the effect of significantly improving the wastewater recycling treatment efficiency.

[0023] By adopting the above technical solution, the connecting vertical rod moves under the drive of the eccentric column, thereby effectively driving the scraper driving rod to move back and forth in a linear direction, causing the connecting driving rod to swing and achieve the purpose of driving the long scraper to move back and forth linearly, so that the transmission connection unit has a compact structure, stable connection and efficient operation.

[0024] The present invention is further configured as follows: the transmission connection unit also includes a transfer L-shaped rod which is rotatably connected to the connecting vertical rod up and down, the transfer L-shaped rod is provided with a bending portion rotating shaft which is rotatably connected to the filter press chamber, the end of the transfer L-shaped rod away from the connection with the connecting vertical rod is bent upward and hinged with a transmission connecting rod, and the end of the transmission connecting rod away from the transfer L-shaped rod is rotatably connected to the scraper driving rod up and down.

[0025] By adopting the above technical solution, when the connecting vertical rod swings under the drive of the eccentric column, the connecting L-shaped rod is driven to make reciprocating swinging motion with the bending part rotating shaft as the axis, thereby achieving the effect of driving the transmission connecting rod to swing and allowing the transmission connecting rod to drive the scraper driving rod to make linear reciprocating movements.

[0026] The present invention is further configured as follows: a plug hole matching and inserting the scraper drive rod is provided at the bottom of the filter press plate; a support connecting frame is provided in the filter press chamber, the output shaft of the drive motor is rotatably connected to the support connecting frame, and the bending portion shaft is rotatably connected to the support connecting frame.

[0027] By adopting the above technical solution, the plug hole is used for the scraper drive rod to pass through and move relative to the filter press plate, and with the support of the supporting connecting frame, the connection stability between the output shaft of the drive motor and the adapter L-shaped rod is significantly improved.

[0028] The present invention is further configured such that: a precipitation transfer roller is fixedly connected to the output shaft of the drive motor, and the precipitation transfer roller is used to transport the impurity precipitation at the bottom of the feed chamber A upward to the upper end, and an inclined sewage transfer part for contacting the outer side wall of the precipitation transfer roller and transporting the precipitation upward is arranged in the pressure filtration chamber.

[0029] By adopting the above technical solution, when the drive motor is running, it will simultaneously drive the precipitation production roller to perform a circumferential rotational movement, so that after the precipitation transfer roller transports the impurity precipitation at the bottom of the feed chamber A upward to the upper end, it is scraped and transported by the inclined sewage transfer part and removed from the feed chamber A, so as to effectively improve the treatment effect and efficiency of construction wastewater.

[0037] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0038] A method for recycling and treating construction wastewater, comprising the following steps:

[0039] Step 1, arrange a primary filtration water storage tank 1, and guide the construction wastewater into the water storage tank A pool 11, and enter the water storage tank B pool 12 above through the water storage tank partition 13 at the lower end of the water storage tank A pool 11, so as to form primary filtered environmental protection wastewater;

[0040] Step 2, the primary filtered environmental wastewater in the water storage tank B 12 is introduced into the filter press chamber 2 through the inclined downpipe 14, and after filter press, it enters the fine filter chamber 3 through the filter press screen 21 to form filter press environmental wastewater;

[0041] Step 3: The filtered environmentally friendly wastewater in the fine filtration chamber 3 is passed through the fine filtration screen 31 and then into the recovery treatment pool 4 to obtain finely filtered environmentally friendly water.

[0042] Therefore, when recycling construction wastewater, impurities exceeding the set size are precipitated on the lower side of the water tank screen 13 when the construction wastewater passes through the primary filtration water tank 1, and primary filtered environmentally friendly wastewater is formed in the water tank B and then filtered through the filter press screen 21 and the fine filtration screen 31 to achieve the recycling of construction wastewater, so that the method for recycling construction environmentally friendly wastewater has the effect of significantly improving the efficiency of wastewater recycling.

[0043] like Figure 1As shown in the figure, two inclined partition plates 131 are arranged at both ends of the reservoir partition net 13 in the primary filtration reservoir 1. The partition plates 131 and the reservoir partition net 13 are used to divide the primary filtration reservoir 1 into the reservoir A pool 11 and the reservoir B pool 12 at both ends. The reservoir partition net 13 is horizontally arranged. Thus, while the inclined partition plates 131 and the reservoir partition net 13 divide the reservoir A pool 11 and the reservoir B pool 12 in the primary filtration reservoir 1, the horizontally arranged reservoir partition net 13 effectively filters the impurities in the construction wastewater. When the construction wastewater passes upward through the reservoir partition net 13, the impurities attached to the reservoir partition net 13 will descend under the action of their own gravity, effectively preventing the impurities from accumulating on the reservoir partition net 13 and affecting the recycling efficiency of the construction wastewater. Therefore, this construction environmental protection wastewater recycling method has the effect of significantly improving the wastewater recycling efficiency.

[0044] As Figure 1 , Figure 2 , Figure 3 shown in the figure, a feed chamber A 23 and a pressure filtration chamber B 24 are arranged in the pressure filtration chamber 2. Among them, the inclined drain pipe 14 is communicated with one end of the feed chamber A 23 far from the pressure filtration chamber B 24. The pressure filtration net 21 is fixed at one end far from the feed chamber A 23, and a pressure filtration plate 8 that moves reciprocally towards and away from the pressure filtration net 21 is arranged in the pressure filtration chamber B 24. It should be noted that the length and width of the pressure filtration plate 8 respectively match the corresponding length and width of the pressure filtration chamber B 24. Thus, during the movement of the pressure filtration plate 8, it plays a role in increasing pressure and driving the primary filtration environmental protection wastewater to pass through the pressure filtration net 21. At the same time, the pressure filtration plate 8 is connected with a driving mechanism for driving the movement, and the driving mechanism is connected with a long strip-shaped scraper 9 for removing the attachments on the surface of the pressure filtration net 21. Therefore, when the primary filtration environmental protection wastewater enters the feed chamber A 23, it automatically flows into the pressure filtration chamber B 24. When the pressure filtration plate 8 moves towards the pressure filtration net 21, the primary filtration environmental protection wastewater in the pressure filtration chamber B 24 will be squeezed towards the pressure filtration net 21, enabling the primary filtration environmental protection wastewater to quickly pass through the pressure filtration net 21. At the same time, the impurities will attach to the pressure filtration net 21 while the pressure filtration net 21 filters the primary filtration environmental protection wastewater. Then, the driving mechanism will drive the long strip-shaped scraper 9 to remove the impurities attached to the pressure filtration net 21, effectively preventing the impurities from accumulating on the pressure filtration net 21 and affecting the recycling efficiency of the construction wastewater. Therefore, this construction environmental protection wastewater recycling method has the effect of significantly improving the wastewater recycling efficiency.

[0045] As Figure 2 , Figure 3 , Figure 4As shown in the figure, the driving mechanism includes a driving motor 5 fixed on the outer side wall of the pressure filtration chamber 2. The output shaft of the driving motor 5 is inserted into the pressure filtration chamber 2 and connected with a driving turntable 6, and an eccentric column 61 is arranged on the driving turntable 6. The eccentric column 61 is rotationally connected with a pushing and pressure filtering rod 86 and a transmission connection unit. One end of the pushing and pressure filtering rod 86 and the corresponding end of the transmission connection unit are sleeved on the eccentric column 61, and the end of the pushing and pressure filtering rod 86 far from the eccentric column 61 is rotationally connected with the pressure filter plate 8 up and down. The transmission connection unit is used to drive the long strip-shaped scraper 9 to make a reciprocating lifting motion in the vertical direction to remove the attached impurity precipitation on the pressure filtration mesh 21 during operation. Furthermore, when the driving motor 5 operates, the driving turntable 6 will be driven by the output shaft to make a circumferential rotational motion with the output shaft as the axis, and then the transmission connection unit and the pushing and pressure filtering rod 86 rotationally connected with the eccentric column 61 will make corresponding movements, so as to achieve the purpose of making the pushing and pressure filtering rod 86 push and pull the pressure filter plate 8 and the transmission connection unit drive the long strip-shaped scraper 9 to make a reciprocating lifting motion in the vertical direction, thereby significantly improving the recovery and treatment efficiency and effect of construction wastewater.

[0046] It should be mentioned that both the upper and lower sides of the long strip-shaped scraper 9 are wedge-shaped to achieve the effect of effectively removing the impurity precipitation on the pressure filtration mesh 21, and a limiting horizontal groove 26 matching the moving direction of the pressure filter plate 8 is arranged in the pressure filtration chamber 2. The pressure filter plate 8 is provided with a limiting insertion block 81 inserted into the corresponding limiting horizontal groove 26 to move. Therefore, during the movement of the pressure filter plate 8, the limiting insertion block 81 moves in the limiting horizontal groove 26, thereby significantly improving the movement stability of the pressure filter plate 8, and thus achieving the purpose of improving the recovery and treatment efficiency and effect of construction wastewater. At the same time, an inclined guiding bottom plate 22 is arranged on the lower side of one end of the pressure filtration chamber B 24 close to the feeding chamber A 23, and a high platform top wall 25 is arranged on the upper side. A gap for the precipitation to pass through is formed between the inclined guiding bottom plate 22 and the lower end of the pressure filter plate 8, and a gap for gas to enter and exit is formed between the high platform top wall 25 and the upper end of the pressure filter plate 8. When the pressure filter plate 8 is pulled by the pushing and pressure filtering rod 86 and moves onto the inclined guiding bottom plate 22, a gap for the precipitation to pass through will be formed between the inclined guiding bottom plate 22 and the lower end of the pressure filter plate 8, and when the movement of the pressure filter plate 8 drives the impurity precipitation to move to one side of the inclined guiding bottom plate 22, the impurity precipitation will move into the feeding chamber A 23 under the guidance of the inclined guiding bottom plate 22, thereby effectively preventing the impurity precipitation from accumulating in the pressure filtration chamber B 24 and affecting the treatment efficiency and effect of the initially filtered environmental protection wastewater, and making the construction environmental protection wastewater recovery and treatment method have the effect of significantly improving the wastewater recovery and treatment efficiency.

[0047] As Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown in the figure, the transmission connection unit includes a connecting vertical rod 83 with one end sleeved on the eccentric column 61. The long strip-shaped scraper 9 is rotatably connected up and down with a connecting driving rod 91. One end of the connecting driving rod 91 far away from the long strip-shaped scraper 9 is rotatably connected up and down with a scraper driving rod 82. The connecting vertical rod 83 is used to drive the scraper driving rod 82 to make a reciprocating motion towards or away from the filter pressing partition net 21. Then, when the connecting vertical rod 83 moves driven by the eccentric column 61, it will effectively drive the scraper driving rod 82 to make a reciprocating motion along the linear direction, and at the same time, make the connecting driving rod 91 swing and achieve the purpose of driving the long strip-shaped scraper 9 to make a reciprocating motion up and down along the line, so that the transmission connection unit has the effects of compact structure, stable connection and high operation efficiency.

[0048] It should be mentioned that the transmission connection unit further includes a connecting L-shaped rod 84 rotatably connected up and down with the connecting vertical rod 83. The connecting L-shaped rod 84 is provided with a bent part rotating shaft 841 rotatably connected with the filter pressing chamber 2. At the same time, one end of the connecting L-shaped rod 84 far away from the connection with the connecting vertical rod 83 is bent upward and hinged with a transmission connecting rod 85, and one end of the transmission connecting rod 85 far away from the connecting L-shaped rod 84 is rotatably connected up and down with the scraper driving rod 82. When the connecting vertical rod 83 makes a swinging motion driven by the eccentric column 61, it drives the connecting L-shaped rod 84 to make a reciprocating swinging motion with the bent part rotating shaft 841 as the axis, so as to realize the effect of driving the transmission connecting rod 85 to swing and making the transmission connecting rod 85 drive the scraper driving rod 82 to make a reciprocating motion along the line.

[0049] In order to effectively improve the running stability of the driving motor 5, a plug hole 821 that matches and inserts the scraper driving rod 82 is provided at the bottom of the filter pressing plate 8. Correspondingly, a support connecting frame 28 is provided in the filter pressing chamber 2. The output shaft of the driving motor 5 is rotatably connected with the support connecting frame 28, and the bent part rotating shaft 841 is rotatably connected with the support connecting frame 28. Among them, the plug hole 821 is used for the scraper driving rod 82 to pass through and make a motion relative to the filter pressing plate 8, and with the support of the support connecting frame 28, the connection stability of the output shaft of the driving motor 5 and the connecting L-shaped rod 84 is significantly improved.

[0050] In order to effectively remove the accumulated impurity precipitation in the pressure filtration chamber 2, a precipitation transfer roller 7 is fixedly connected to the output shaft of the drive motor 5. The precipitation transfer roller 7 is used to transport the impurity precipitation at the bottom of the feed chamber A 23 upward, so that after the impurity precipitation is driven by the precipitation transfer roller 7 to rotate upward, it is then transported upward under the action of the inclined sewage transfer part 27 arranged in the pressure filtration chamber 2 and used to contact the outer wall of the precipitation transfer roller 7. The inclined sewage transfer part 27 is provided with devices such as a conveyor belt for transporting items, which belongs to the prior art and will not be elaborated here. Therefore, when the drive motor 5 operates, it will simultaneously drive the precipitation transfer roller to perform a circumferential rotational movement, so that after the precipitation transfer roller 7 transports the impurity precipitation at the bottom of the feed chamber A 23 upward, it is scraped and transported by the inclined sewage transfer part 27 and removed from the feed chamber A 23, so as to effectively improve the treatment effect and efficiency of construction wastewater.

[0051] In summary, in this application, the construction wastewater is filtered and treated in sequence by the reservoir partition net 13, the pressure filtration partition net 21, and the fine filtration partition net 31, and combined with the simultaneous movement of the drive motor 5 to drive the pressure filtration plate 8, the long strip-shaped scraper 9, and the precipitation transfer roller 7, so as to achieve the purpose of improving the efficiency of the primary filtered environmental protection wastewater passing through the pressure filtration partition net 21, avoiding the influence of impurity precipitation adhering to the pressure filtration partition net 21 on the effect of the primary filtered environmental protection wastewater passing through the pressure filtration partition net 21, and removing the impurity precipitation in the feed chamber A 23 to avoid affecting the filtration effect of the pressure filtration partition net 21 on the primary filtered environmental protection wastewater, making the construction wastewater recycling and treatment method have the effect of significantly improving the wastewater recycling and treatment efficiency.
