Description

Technical Field

[0001] The invention relates to the technical field of environmental engineering, in particular to an ecological flow control type comprehensive pollution interception structure. Background Art

[0002] At present, agricultural non-point source pollution is an important cause of the deterioration of water bodies such as rivers, lakes and reservoirs, and has become a core issue that urgently needs to be addressed in the water ecological environment. Agricultural non-point source water pollution mainly includes rural domestic sewage, livestock and fishery wastewater, and agricultural production sewage in a broad sense. It is wide-area, dispersed, hidden, large in volume, and relatively light in pollution. However, once pollution is formed, the pollution cycle is long, the harmful impact is large, and the control is difficult. The mature industrial point source intensive sewage treatment model responds to agricultural non-point source water pollution, and practice has proved that the cost of control is high. With the rise of ecological governance models, ecological governance technologies such as ecological ditches, ecological ponds, stabilization ponds, and artificial wetlands have been widely used in the control of agricultural non-point source water pollution, and have achieved good governance results.

[0003] In the process of using ecological technology to treat agricultural non-point source sewage, floating objects and suspended matter carried by the sewage flow into the ecological engineering system, accumulate and settle. If effective pollution interception measures are not taken, it is easy to block the flow channel of the ecological engineering, reduce the purification function of the ecological engineering, and shorten the service life. Conventional pollution interception technology generally installs trash racks and nets at the inlet and outlet, which can intercept certain floating objects and suspended matter, but the interception effect on small-volume floating objects and suspended matter and sediment particles in the water body is not ideal, and the intercepted floating objects and suspended matter are more likely to block the pollution interception structure. In addition, this type of pollution interception structure can rarely control the upstream water level and ensure the downstream ecological flow demand. Summary of the invention

[0004] In response to the technical problems existing in the prior art, the present invention proposes an ecological flow control comprehensive pollution interception structure, which overcomes the problems of traditional pollution interception structures such as single function, limitations, and easy clogging. It can comprehensively intercept floating objects, suspended matter, and sediments carried by upstream water, effectively control the flow and ensure the downstream ecological flow demand. It has the advantages of efficient and comprehensive pollution interception, stable regulation and control of flow, and guarantee of downstream ecological flow.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an ecological flow control integrated pollution interception structure, comprising a grit chamber, and a flow component arranged on the first side wall of the grit chamber; the grit chamber is divided into a water flow section, a transition section, and a sedimentation section which are connected in sequence, the height of the bottom of the water flow section is greater than the height of the bottom of the sedimentation section, the longitudinal section of the transition section is constructed as an inverted S-shaped structure, and the incoming water passes through the water flow section, the transition section, and the sedimentation section in sequence and is discharged from the flow component into the downstream water body.

[0006] As a further technical solution, the height of the second side walls symmetrically arranged on both sides of the grit chamber is greater than the height of the first side walls.

[0007] As a further technical solution, the flow component is buried in the first side wall, and the water inlet thereon is connected to the water inlet section in the first side wall, and the water outlet is arranged on the outer wall of the first side wall to connect with the downstream water body.

[0008] As a further technical solution, the opening of the water inlet section gradually decreases along the water flow direction.

[0009] As a further technical solution, the water outlet of the water inlet section is located at the top thereof to communicate with the flow-through component.

[0010] As a further technical solution, the flow assembly includes a plurality of elbows with Z-shaped longitudinal sections, a plurality of connecting elbows, and a plurality of connecting pipes, each of the elbows is provided with at least one water inlet along its height direction, and the water inlet of each of the elbows is connected to one of the connecting elbows; The water inlets below the top of the elbow are connected to the connecting elbow through a connecting pipe, and the water inlet of the connecting elbow is connected to the water outlet at the top of the water inlet section; The water outlet of the water inlet section is communicated with the connecting elbow.

[0011] As a further technical solution, a first group of water inlet sections is provided on the mid-vertical plane of the first side wall, and the first group of water inlet sections is provided with a second group of water inlet sections, a third group of water inlet sections, and a fourth group of water inlet sections in a symmetrical structure in sequence along the left and right sides of the mid-vertical plane of the first side wall, and the heights of the elbows connected to the second group of water inlet sections, the third group of water inlet sections, and the fourth group of water inlet sections are arranged in an arithmetically ascending manner in sequence; The height of the elbow connected to the first group of water inlet sections is consistent with the height of the elbow connected to the fourth group of water inlet sections.

[0012] As a further technical solution, the first group of water inlet sections is provided with a plurality of water inlet sections arranged in an equidistant manner along its height direction.

[0013] As a further technical solution, a filter or a plug is provided in the connecting elbow.

[0014] The beneficial effects of the present invention are: 1. The structural design of the water flow section, transition section and sedimentation section in the grit chamber can optimize the flow pattern, reduce water turbulence, and facilitate the sedimentation of suspended particles. In addition, submerged plants are planted at the bottom of the grit chamber to degrade and absorb the settled nutrients; 2. The structural design of the flow assembly and the water inlet section on the first side wall utilizes the principle of water pressure height difference. The flow channel can only be formed when the upstream water level is higher than the connecting elbow and the elbow or the connecting pipe. Reasonable design of the length of the connecting elbow can effectively intercept floating objects in the water body; and then by choosing to install a filter or a plug at the connecting elbow, the opening (installation of a filter) or closing (installation of a plug) of the flow channel can be independently controlled to stably regulate the upstream water level, hydraulic retention time and downstream ecological flow. In addition, the installation of a filter can effectively intercept suspended matter in the water body, and the downward-facing inlet of the connecting elbow can effectively prevent suspended matter from clogging the filter element; finally, by controlling the height of the water inlet section and the height of the water inlet of the flow channel, the dead water level can be lowered, and at the same time, the settled particles can be prevented from disturbing the water when entering the downstream water body.

[0015] The structure of the present invention can ultimately achieve the purpose of comprehensively intercepting floating objects, suspended objects, and sediments carried by upstream water, stably regulating the upstream water level, and controlling the hydraulic retention time and downstream ecological flow through the grit chamber and the flow-through component arranged on the first side wall of the grit chamber.

[0021] Example 1 In order to overcome the problems of single functionality and easy clogging of traditional pollution interception structures, and to achieve comprehensive interception of floating objects, suspended matter and sediments carried by upstream water, and effectively control the flow to ensure the needs of downstream ecological flow, it has the advantages of efficient and comprehensive pollution interception, stable regulation and control of flow, and guarantee of downstream ecological flow; Taking the small watershed comprehensive management project involving agricultural non-point source water pollution around an important water source protection area in a certain mountainous area as an example, it includes rural domestic sewage, domestic livestock and poultry breeding wastewater, agricultural sewage mainly based on farmland planting, rainfall runoff, etc. According to the local terrain characteristics, the small watershed comprehensive management project adopts micro-topography local transformation. The above-mentioned incoming water is collected through ecological ditches, and enters the stabilization pond, ecological pond, and artificial wetland system in turn for treatment before entering the natural water body. The pollution interception structure of this embodiment is mainly installed at the outlet of the ecological ditch, the inlet or outlet of the pond / wetland, and the overflow weir of a small river. The following will be combined with the accompanying drawings to further introduce the engineering examples of the present invention in detail.

[0022] This embodiment provides an ecological flow control integrated pollution interception structure, see Figure 1-Figure 3 , including a grit chamber 1, and a flow assembly 2 arranged on a first side wall 11 of the grit chamber 1; the grit chamber 1 is divided into a water flow section 12, a transition section 13, and a sedimentation section 14 connected in sequence, the height of the bottom of the water flow section 12 is greater than the height of the bottom of the sedimentation section 14, the longitudinal section of the transition section 13 is an inverted S-shaped structure, and the incoming water passes through the water flow section 12, the transition section 13, and the sedimentation section 14 in sequence and is discharged from the flow assembly 2 into the downstream water body.

[0023] The flow component 2 is used to discharge the water in the grit chamber 1 after filtering out floating objects, suspended objects, sediments, etc. into the downstream water body; The arrangement of the water flow section 12, the transition section 13, and the sedimentation section 14 in the grit chamber 1 can optimize the flow pattern of the water flow, that is, the water flows in the directions of the water flow section 12, the transition section 13, and the sedimentation section 14 in sequence to reduce the turbulence of the water body and facilitate the sedimentation of suspended particles. Planting submerged plants (not shown in the figure) at the bottom of the grit chamber 1 can degrade and absorb the settled nutrients. The longitudinal section of the transition section 13 can also be a curved surface. The size of the grit chamber 1 is determined by comprehensive design based on the flow rate of incoming water, flow capacity, sand settling and water purification effects. For example, the grit chamber 1 is about 5 meters long, about 1.8 meters wide, and about 0.5 meters deep. The radius of the upper semicircle of the transition section 13 of the inverted S-shaped structure is 0.25 meters. The submerged plants planted at the bottom of the grit chamber 1 are selected from native submerged plants that are durable, resistant to pollution, have developed root systems, good decontamination effects, have certain economic value, and are easy to manage. One or more plants can be selected for planting, and the planting density is determined according to the plant type. For example, at this time, it can be Elodea and Hydrilla, and the planting density is 6 to 8 plants / m 2 ; For example, the first side wall 11 is a retaining wall structure, which is 1.3 meters high and 1.8 meters wide, and its bottom is flush with the bottom of the sand settling tank 1. The retaining wall can be selected from natural earth walls, mortar-laid stone walls, artificial composite walls and other types.

[0024] Furthermore, the height of the second sidewalls 15 symmetrically arranged on both sides of the grit chamber 1 is greater than the height of the first sidewall 11. That is, the hexahedral structure has one first sidewall 11, two symmetrically arranged second sidewalls 15, and the other sidewall is open for water to enter.

[0025] It can be explained that the flow component 2 is buried in the first side wall 11, and the water inlet thereon is connected with the water inlet section 111 in the first side wall 11, and the water outlet is arranged on the outer wall of the first side wall 11 to be connected with the downstream water body, so that the water body purified by the grit tank 1 passes through the water inlet of the first side wall 11 through the flow component 2 and then passes into the downstream water body from the water outlet of the first side wall 11. In this process, the floating objects, suspended objects, etc. carried in the sewage can be effectively intercepted.

[0026] Further, see Figure 4-Figure 7 The opening of the water inlet section 111 gradually decreases along the direction of water flow. When the water level in the grit tank 1 is higher than the water inlet section 111, due to the principle of water pressure height difference, a flow channel is formed, which can effectively intercept floating objects in the grit tank 1, and the intercepted floating objects can be manually salvaged and processed in the grit tank 1 from time to time; further, the water inlet section 111 is connected to the flow component 2, so that the water body that intercepts the floating objects flows to the downstream water body outside the grit tank 1 through the flow component 2.

[0027] In the specific implementation process, see Figure 4 , Figure 5 , Figure 7 The flow component 2 includes a plurality of elbows 21 with a Z-shaped longitudinal section, a plurality of connecting elbows 22, and a plurality of connecting pipes 23. Each of the elbows 21 is provided with at least one water inlet along its height direction, and the water inlet of each of the elbows 21 is connected to a connecting elbow 22; The water inlet below the top of the curved pipe 21 is connected to the connecting elbow 22 through the connecting pipe 23 , and the water inlet of the connecting elbow 22 is connected to the water outlet at the top of the water inlet section 111 ; the water outlet of the water inlet section 111 is connected to the connecting elbow 22 .

[0028] That is, when the water level in the sedimentation tank 1 is higher than the connection point between the connecting elbow 22 and the elbow 21 or the connecting pipe 23, the water inlet of the connecting elbow 22 is submerged. Due to the principle of high pressure difference, floating objects in the upstream water cannot enter the water inlet of the connecting elbow 22, and the water body with suspended objects intercepted is discharged into the downstream water body through the outlet of the flow component 2.

[0029] For example, one curved pipe 21 is connected with at least two of the connecting elbows 22, such as three of the connecting elbows 22. Then, two other connecting elbows 22 are sequentially arranged on the straight pipe section of the curved pipe 21, and the connecting elbow 22 is connected to the corresponding curved pipe 21 through the connecting pipe 23. Furthermore, the three connecting elbows 22 on the curved pipe 21 share a common longitudinal center line, so that water at different water levels in the grit chamber 1 can be discharged to the downstream water body through the flow component 2.

[0030] In the specific implementation process, see Figure 2 A first group of water inlet sections 112 is provided on the mid-vertical plane of the first side wall 11, and a second group of water inlet sections 113, a third group of water inlet sections 114, and a fourth group of water inlet sections 115 are sequentially provided with symmetrical structures along the left and right sides of the mid-vertical plane of the first side wall 11, and the heights of the elbows 21 connected to the second group of water inlet sections 113, the third group of water inlet sections 114, and the fourth group of water inlet sections 115 are sequentially arranged in an arithmetically ascending manner; The height of the curved pipe 21 connected to the first group of water inlet sections 112 is consistent with the height of the curved pipe 21 connected to the fourth group of water inlet sections 115 .

[0031] The first group of water inlet sections 112 is provided with a plurality of water inlet sections 111 arranged in an equidistant manner along its height direction.

[0032] For example, see Figure 2 , Figure 4-Figure 7 , the first group of water inlet sections 112 is provided with four water inlet sections 111, and each of the water inlet sections 111 is connected to a connecting elbow 22, and the water inlet section 111 located at the top is connected to the water inlet of the elbow 21, and the water outlet of the elbow 21 is connected to the downstream water body outside the first side wall 11, and the remaining three water inlet sections 111 are connected to the elbow 21 through the connecting elbow 22 and the connecting pipe 23 in sequence to achieve the discharge of different water levels in the grit chamber 1; the four water inlet sections 111 in the first group of water inlet sections 112 have a common center line in the height direction; At this time, see Figure 6-Figure 8 The second group of water inlet sections 113 and the fourth group of water inlet sections 115 on the left or right side of the vertical plane of the first side wall 11 are each provided with only one water inlet section 111, and the third group of water inlet sections 114 are provided with two water inlet sections 111 and a connecting pipe 23, each connected to a curved pipe 21; and the heights of the curved pipes 21 connected to the second group of water inlet sections 113, the third group of water inlet sections 114, and the fourth group of water inlet sections 115 are arranged in an equidistant ascending manner. Furthermore, seven elbows are arranged on the first side wall 11, wherein the first group of water inlet sections 112 are connected to a bend 21 via a connecting elbow 22 and a connecting pipe 23 (it can be explained that the water inlet at the top of the bend 21 is directly connected to the connecting elbow 22, and the other connecting elbows 22 arranged on the bend 21 are connected via a connecting pipe 23); the second group of water inlet sections 113 and the fourth group of water inlet sections 115 on the left and right sides of the mid-vertical plane are respectively connected to a bend 21 via a connecting elbow 22, and the third group of water inlet sections 114 are connected to The first group of water inlet sections 112 are the same, the only difference is that two water inlet sections 111 are provided thereon; the elbows 21 connected to the groups of water inlet sections (112, 113, 114, 115) are projected on the median vertical plane at four equidistant heights, which are 0.2 meters, 0.5 meters, 0.8 meters, and 1.1 meters respectively, and the lateral spacing between adjacent elbows is 0.25 meters; it can be explained that the first side wall 11 is arranged with three water inlet sections 111 and connecting elbows 22 at 0.2 meters, 0.5 meters, 0.8 meters, and 1.1 meters.

[0033] By installing a filter element or a plug (not shown in the figure) on the elbow 21 connected to the four water inlet sections 111 of equidistant heights on the first side wall 11, it is possible to adjust the upstream water level and control the hydraulic retention time and the downstream flow rate; in addition, the water inlet of the elbow 21 faces downward, and the installed filter element can effectively prevent the suspended matter from clogging the filter element when intercepting the suspended matter in the water body; if the filter element is a multi-stage filter cylinder, the length can be 0.08 meters, for example, 3 multi-stage filter screens, and the plug can be a metal structure, which is connected to the water inlet of the corresponding elbow 21 by a thread.

[0034] The present invention is achieved in that: After the water enters the sedimentation tank 1, it passes through the water flow section 12, the transition section 13 and the sedimentation section 14 in sequence. In this process, the flow pattern of the water flow can be optimized, the turbulence of the water body can be reduced, and the sedimentation of suspended particles can be facilitated. Submerged plants are planted in the tank to degrade and absorb the nutrients that settle. Afterwards, the water level of the grit chamber 1 is higher than the connection point between the connecting elbow 22 and the elbow 21 or the connecting pipe 23, and a filter is installed in the connecting elbow 22 to form a flow channel. The water level submerges the elbow 21, which can intercept floating objects in the water body (the floating objects can be salvaged and disposed of from time to time). At the same time, the water body flows into the connecting elbow 22 where the filter is installed. In this process, due to the effect of the filter, the suspended matter in the water body can be effectively intercepted. In addition, the downward setting of the water inlet of the connecting elbow 22 can effectively prevent the suspended matter from hanging on the net and clogging the filter screen; conversely, the water level of the grit chamber 1 is higher than the connection point between the connecting elbow 22 and the elbow 21 or the connecting pipe 23, and a plug is installed in the connecting elbow 22 to close the flow channel of the water inlet section 111. By closing and opening the number of flow channels of the water inlet section 111 at different heights, the upstream water level, the hydraulic retention time and the downstream flow rate can be accurately controlled; In addition, the height of the water inlet of the connecting elbow 22 located at the bottom of the first side wall 11 is designed to be greater than the height of the bottom of the sedimentation section 14 and less than the height of the bottom of the water flow section 12. The length of the elbow 21 and the height of its water inlet can be reasonably controlled according to needs, that is, the dead water level is lowered and the settled particles are prevented from disturbing and re-entering the downstream water body.

[0035] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0037] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
