Description

Technical Field

[0001] The present invention relates to the technical field of water treatment devices, in particular to a reclaimed water treatment device. Background Art

[0002] Grey water, also known as recycled water, is water obtained from wastewater or rainwater that has been properly treated and meets certain water quality indicators. It can be used within a certain range to alleviate water resource pressure. Existing grey water treatment devices require various filtering and disinfection devices during use. Their structures are relatively complex. Generally, membrane filtration is used to make water flow along the surface of the filter membrane under the action of external force and filter related impurities when passing through the filter membrane. However, the cost of the filter membrane is relatively high, and in the grey water treatment process, there are relatively too many impurities, so the filter membrane needs to be replaced frequently, which greatly increases the cost of use. Moreover, frequent replacement of the filter membrane generally requires water outage, which also delays production and wastes time. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the present invention provides a reclaimed water treatment device, which solves the problem that the use cost is relatively high and the replacement is relatively troublesome when filtering reclaimed water through the existing membrane filtration method.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A reclaimed water treatment device includes a wall for holding water flow, a water inlet area is provided at one end of the wall, a water purification area is provided on one side of the water inlet area, and a water outlet area for supplementary disinfection is provided on the side of the water purification area away from the water inlet area, and a water purification mechanism is provided in the water purification area.

[0006] The water purification mechanism includes a plurality of gate assemblies vertically arranged in the water purification area, which discharge water from the bottom. A partition is provided between two adjacent gate assemblies to cooperate with them to guide the water flow to fold up and down. A plurality of detachable adsorption assemblies for purifying the water flow are provided between the partition and the gate assembly, and green plants for sterilization are provided on the top of the adsorption assembly.

[0007] Preferably, the gate assembly includes a water-blocking member fixed on the wall for limiting the flow of water, and a plurality of water outlets for the circulation of water are provided at the bottom of the water-blocking member.

[0008] Preferably, the water-blocking component includes a U-shaped door frame fixed to the wall, with limiting plates fixed on both sides of the U-shaped door frame for guiding the water flow from the bottom, and multiple gate plates sliding up and down between the two limiting plates for controlling the number of water outlets, and multiple fixing holes provided on the upper part of the gate plate, and at least one fixing hole provided with a fixing plate passing through the limiting plate.

[0009] Preferably, the adsorption assembly includes a plurality of stacked porous filter materials in block shape arranged in the water purification area. A pebble filter material is provided on the top of the porous filter material to cooperate with it to remove suspended matters. A plurality of support members for fixing the porous filter material and the pebble filter material are provided in the water purification area.

[0010] Preferably, the support member includes a bottom plate fixed to the bottom wall of the wall body. A plurality of positioning plates vertically fixed to the bottom plate and clamped with the porous filter material are provided. A mesh bag for containing the pebble filter material is fixed between two adjacent positioning plates.

[0011] Preferably, an impurity removal mechanism for removing particulate precipitates is provided in the water inlet area. The impurity removal mechanism includes a water inlet pipe fixed to the upper part of the side wall of the wall body. A U-shaped diversion plate fixed to the upper part of the wall body for guiding water flow to flow from the bottom wall of the wall body is provided. A plurality of first baffles vertically fixed to the bottom wall of the wall body for blocking the flow of particulate matter precipitation are provided.

[0012] Preferably, a plurality of second baffles respectively located above the corresponding first baffles are fixed to the bottom of the U-shaped diversion plate. Diversion plates for guiding water flow to flow upward and downward respectively are fixed to the wall body on the sides of the first baffle and the second baffle.

[0013] Preferably, a disinfection mechanism for supplementary disinfection is provided in the water outlet area. The disinfection mechanism includes a water outlet pipe fixed to the bottom of the side of the wall body away from the water purification area. A diversion block for guiding water flow to flow upward is provided between the water outlet pipe and the water purification area. A disinfection pipe for spraying disinfectant is fixed to the wall body above the diversion block.

[0014] Compared with the prior art, the present invention provides a medium water treatment device, which has the following beneficial effects:

[0015] A plurality of adsorption assemblies arranged in the water inlet area cooperate with a plurality of green plants for sterilization arranged on the top of the adsorption assemblies. The combination of the two can, on the one hand, achieve the effect of filtering and purifying sewage, separate suspended substances, colloidal substances, etc. in the wastewater from the purified water, and simultaneously eliminate bacteria and other microorganisms in the water through the sterilization effect of the green plants, so that the purified reclaimed water meets certain usage standards. By forming individual filtering units through the cooperation of the porous filter material made of light stone material as the main filtering body in the adsorption assembly and the support members, the disassembly, cleaning and maintenance of the adsorption assembly are more convenient. The combination of the light porous filter material made of light stone material and the pebble filter material forms a unique buoyancy ratio, which can scientifically prevent the blockage of the porous filter material, so that the filtering effect of the device is more stable during use, and at the same time, the purpose of cost saving and convenient maintenance is achieved.

[0016] A plurality of groups of symmetrically arranged first baffles and second baffles disposed at the bottom of the water inlet area cooperate with a flow splitter plate. By utilizing the flow splitting effect of the flow splitter plate and the flow merging effect of the first baffle and the second baffle, the momentum of the sewage after being pumped into the water inlet area by the water pump is eliminated, its flow velocity is slowed down, thereby increasing the purification time of the sewage, and more fully filtering out larger particulate sediments in the sewage, so that the single use time of the adsorption component is longer, the maintenance frequency is reduced, and the impurities at the bottom of the water inlet area can also be assembled into a chain-like whole by the first baffle, the second baffle and the flow splitter plate, thus facilitating quick replacement and dredging.

Detailed implementation mode

[0027] The following will be combined with the drawings and embodiments to detail the implementation mode of the present application, so as to fully understand and implement how the present application uses technical means to solve technical problems and achieve technical effects.

[0028] Figures 1-8 As an embodiment of the present invention, a more environmentally friendly and low-cost filtration method is used to treat water resources, replacing the membrane filtration method, and it is convenient to maintain during the treatment process, thereby reducing material costs while increasing the filtration volume.

[0029] A medium water treatment device includes a wall 1 for holding water flow. The wall 1 encloses a channel for guiding the water flow. One end of the wall 1 is provided with a water inlet area 11, and sewage enters the wall 1 from the water inlet area 11. A water purification area 12 is provided on one side of the water inlet area 11. The water flow is purified when passing through the water purification area 12. A water outlet area 13 for supplementary disinfection is provided on the side of the water purification area 12 away from the water inlet area 11. The water outlet area 13 stores water while cooperating with the water purification area 12 for purification. A water purification mechanism 2 is provided in the water purification area 12. The water purification mechanism 2 is used to filter and disinfect the passing sewage to achieve the purification of the sewage.

[0030] The water purification mechanism 2 includes a plurality of gate assemblies 21 vertically arranged in the water purification area 12 and discharging water from the bottom. A partition 22 is provided between adjacent two gate assemblies 21 to cooperate with them to guide the water to flow in a folded manner up and down. The gate assembly 21 allows the water to pass through its bottom, and the partition 22 allows the water to flow over its top. The two cooperate to make the water advance alternately from the upper and lower parts of the water purification area 12 when passing through the water purification area 12, so as to extend the residence time of the sewage in the water purification area 12 as much as possible, so that as many impurities in the sewage can be filtered out as possible. A plurality of detachable adsorption assemblies 23 for purifying the water flow are provided between the partition 22 and the gate assembly 21. The adsorption assemblies 23 are filled in the blank area between the partition 22 and the gate assembly 21, which is convenient for disassembly and replacement during maintenance. And by sequentially replacing each adsorption assembly 23, the adsorption assemblies 23 can be maintained and replaced synchronously during the intermediate water treatment process, so as to increase the sewage treatment volume. And the adsorption assembly 23 can use light stone that meets the filtration effect and has a lower price as its filtration main body to filter the sewage, so as to save costs. A green plant 24 for sterilization is provided at the top of the adsorption assembly 23. The secretions generated by the rhizomes of some types of green plants 24 during growth are used to sterilize the sewage, which is low-carbon and environmentally friendly and is also simpler to manage and maintain the plants. Therefore, through the above structure, the maintenance process of the device is simplified and the cost is lower. At the same time, the filtration volume of the sewage is also increased by the way of synchronously maintaining during the intermediate water filtration process.

[0031] As a preferred technical solution of this embodiment, the gate assembly 21 includes a water blocking member 211 fixed on the wall 1 to limit the water flow. A plurality of water outlets 212 for water flow are provided at the bottom of the water blocking member 211. The number of the water outlets 212 is reasonably determined according to the required water flow rate, so that the water passes through the water outlets 212 located at the bottom of the gate assembly 21 when passing through the gate assembly 21, so as to cooperate with the partition 22 to make the water flow in a meandering manner, extend the filtration time of the sewage, and improve the filtration effect.

[0032] As a preferred technical solution of this embodiment, the water-blocking member 211 includes a U-shaped door frame 2111 fixed to the wall 1. The U-shaped door frame 2111 serves as an installation carrier. On both sides of the U-shaped door frame 2111, there are fixed limit plates 2112 for guiding water to flow from the bottom. The limit plates 2112 are used to prevent water from flowing through the middle or upper part, so that sewage can only flow through the water outlet 212 located at the bottom. Between the two limit plates 2112, there are slidably arranged a plurality of gate plates 2113 for controlling the number of water outlets 212. On the upper part of the gate plates 2113, there are a plurality of fixing holes 2114. At least one fixing hole 2114 is provided with a fixing plate 2115 passing through the limit plate 2112. By sliding the gate plates 2113 and fixing the gate plates 2113 through the fixing plate 2115 inserted into the fixing holes 2114, the number and cross-sectional area of the water outlets 212 can be controlled by reasonably controlling the number of the upward-sliding gate plates 2113, realizing more diversified adjustment, so that the water flow can fully meet the process requirements.

[0033] As a preferred technical solution of this embodiment, the adsorption assembly 23 includes a plurality of stacked block-shaped porous filter materials 231 arranged in the water purification area 12. The porous filter materials 231 can be made of volcanic pumice as raw materials. Preferably, they can be made of glass pumice prepared by the waste glass foaming process to embody the concept of waste resource utilization. At the same time, when applied to the reclaimed water regeneration link, the physical properties of the glass pumice can be fully utilized. The micropores of the pumice are in full contact with the sewage, and the filtration of impurities in the water can be fully realized. On the top of the porous filter materials 231, there is a pebble filter material 232 which cooperates with it to remove suspended matter. By cooperating with the porous filter materials 231, efficient solid-liquid separation can be carried out, separating the suspended substances, colloidal substances, etc. in the wastewater from the purified water. In the water purification area 12, there are a plurality of support members 233 for fixing the porous filter materials 231 and the pebble filter materials 232. Through a large number of support members 233, the plurality of porous filter materials 231 and the pebble filter materials 232 are respectively integrated into individual filtering units. Thus, during maintenance, only by sequentially replacing each filtering unit can the maintenance be completed. The maintenance cost is relatively low, and there is no need to shut down the equipment, which is more convenient.

[0034] As a preferred technical solution of this embodiment, the support member 233 includes a bottom plate 2331 fixed to the bottom wall of the wall body 1. Vertically fixed on the bottom plate 2331 are a plurality of positioning plates 2332 that are snap-connected to the porous filter material 231. A mesh bag 2333 for containing pebble filter material 232 is fixed between two adjacent positioning plates 2332. The porous filter material 231 located in the middle is snap-connected by two adjacent positioning plates 2332, thereby preventing the porous filter material 231 from being misaligned during replacement, increasing the maintenance difficulty, and making the position of the porous filter material 231 more accurate, so as to prevent the gap between adjacent porous filter materials 231 from increasing during maintenance and affecting the filtration effect. Also, during maintenance, a spare support member 233 can be used and the porous filter material 231 can be loaded into it, thereby accelerating the maintenance and replacement process, avoiding the reduction of the porous filter material 231 and affecting the filtration effect. At the same time, the mesh bag 2333 is used to place the pebble filter material 232. The gravity of the pebble filter material 232 can, on the one hand, make the adjacent porous filter materials 231 more dense, and at the same time filter some small floating objects with smaller diameters through the pebble filter material 232, and cooperate with the porous filter material 231 to better achieve the purification of water quality.

[0035] As a preferred technical solution of this embodiment, an impurity removal mechanism 3 for removing particulate sediments is provided in the water inlet area 11. The impurity removal mechanism 3 includes a water inlet pipe 31 fixed to the upper part of the side wall of the wall body 1. Sewage is sent into the water inlet pipe 31 by a water pump and finally enters the water inlet area 11. A U-shaped diversion plate 32 for guiding the water flow to flow from the bottom wall of the wall body 1 is fixed to the upper part of the wall body 1. After the sewage enters the water inlet area 11, the U-shaped diversion plate 32 causes the sewage to quickly drop and flow along the bottom of the water inlet area 11 into the water purification area 12. Vertically fixed on the bottom wall of the wall body 1 are a plurality of first baffles 33 for blocking the flow of particulate matter precipitation. Although some larger-volume impurities have been filtered during the water pump pumping process, some small particulate matter with relatively large densities, such as hard impurities like sand and gravel particles, is also easily sucked in. During the flow of the sewage at the bottom of the water inlet area 11, under the action of gravity, the particulate matter with relatively large densities will gradually settle. At this time, the first baffles 33 block the gradually settling particulate matter with relatively large densities, so that it can settle quickly, avoiding the filter holes of the porous filter material 231 at the water outlet 212 being directly blocked by particulate matter with larger diameters and greater hardness, thereby affecting the overall filtration effect of the adsorption assembly 23.

[0036] As a preferred technical solution of this embodiment, a plurality of second baffles 34 are fixed to the bottom of the U-shaped deflector 32, each of which is located above a corresponding first baffle 33. On the wall 1 on the side of the first baffle 33 and the second baffle 34, a flow splitter 35 is fixed for guiding the water flow to flow upward and downward respectively. The water flow pumped into the water inlet area 11 by the water pump has a relatively large power during the flowing process. When the water flow passes through the flow splitter 35, it is divided into two water flows and moves to the upper and lower sides. Subsequently, blocked by the second baffle 34 and the first baffle 33, the water flow will flow to the gap between the second baffle 34 and the first baffle 33, so that the two water flows in opposite directions collide, consuming the power of the water flow itself and reducing its flow velocity. On the one hand, it makes the water flow slower when passing through the bottom of the water inlet area 11, so that the residence time is longer, enabling more particulate impurities to precipitate, preventing it from directly blocking the pores of the porous filter material 231 at the water outlet 212 and making the sewage unable to pass through. On the other hand, weakening the power of the water also prevents it from stirring the sediment at the bottom of the water inlet area 11, thus avoiding the sediment being re-suspended and causing secondary pollution, realizing the pretreatment of the harder particulate sediment in the sewage, facilitating the subsequent adsorption assembly 23 to adsorb the fine impurities in the water, and thus better realizing the purification of the sewage.

[0037] As a preferred technical solution of this embodiment, a disinfection mechanism 4 for supplementing disinfection is provided in the water outlet area 13. The disinfection mechanism 4 includes a water outlet pipe 41 fixed to the bottom of the wall 1 on the side away from the water purification area 12. A flow guiding block 42 for guiding the water flow to flow upward is provided between the water outlet pipe 41 and the water purification area 12. A disinfection pipe 43 for spraying disinfectant is fixed on the wall 1 above the flow guiding block 42. The flow guiding block 42 is used to control the cross-sectional area of the water flow when passing below the disinfection pipe 43, so as to cooperate with the disinfection pipe 43 to enable the disinfectant sprayed from the disinfection pipe 43 to fully disinfect the water flowing below it, ensuring the disinfection effect. And because the green plants 24 for sterilization have seasonal properties, the disinfection pipe 43 can complement the green plants 24. During the growth season of the green plants 24, the green plants 24 can be used for disinfection to save costs. In the non-growth season of the green plants 24 or when the green plants 24 die accidentally, the disinfection pipe 43 can disinfect the water flow, thus fully ensuring the disinfection effect of the water.
