Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ecological environment governance, in particular to an ecological rural river restoration method. BACKGROUND

[0002] Rural rivers bear basic functions such as agricultural irrigation, drainage, flood regulation, and ship transportation, and are also important carriers of ecology and environment in rural areas.

[0003] At present, the methods for restoring urban river water bodies can be roughly divided into physical methods, chemical methods, and biological-ecological methods.

[0004] Physical methods for restoration include aeration, sewage interception, and river dredging. If artificial aeration measures are taken at appropriate locations in the river, the activity of aerobic microorganisms in the water body can be improved, thereby reducing water pollution and achieving the purpose of improving water quality. Sewage interception is also an effective way to restore water bodies using physical methods. France invested 5.6 billion euros in sewage interception and treatment of the Seine River from 1991 to 2001, and the sewage treatment rate increased by 30% based on the original, with remarkable results. Wang Dong et al. studied the removal of 30% of phosphorus in the bottom mud of the Wuli Lake area in Taihu Lake through dredging and other physical methods, and also had good results in removing water body nutrients. However, river dredging measures often cannot completely solve the problem of water pollution. Pu Peimin et al. analyzed that river dredging engineering has important utility as a water conservancy and channel engineering measure, and the effect of improving water quality is related to the dredging method. Proper dredging can improve water quality in the short term, but in the long term, dredging of bottom mud is not an effective measure to control lake eutrophication. Physical methods often treat the symptoms rather than the root cause, and are not the ultimate solution to the problem.

[0005] Chemical methods for water pollution control mainly through chemical fixation and chemical algae removal two ways. Chemical fixation is mainly through chemical substances precipitate water phosphorus or heavy metals in the sediment, and prevent its release from the sediment again. Studies have shown that Ca (NO3) 2, can effectively degrade organic matter in the sediment and inhibit the release of phosphorus in the sediment. Chemical algae removal is mainly through the addition of chemicals to inhibit the proliferation of algae in polluted water, such as copper sulfate algae removal agent, non-oxidizing algae removal agent, etc. Ningping et al. aimed at the outbreak of cyanobacteria in Dianchi Lake, and found that the type of flocculant and pH value had an effect on the removal rate of cyanobacteria. However, the use of chemical methods often causes secondary pollution of water bodies. Li Jianhong et al. found that copper ions in copper sulfate can act on the phycobilisome of cyanobacteria, thereby inhibiting the photosynthesis of cyanobacteria and achieving the effect of killing algae. However, the use of copper sulfate for chemical algae removal can kill a large number of microorganisms and destroy the water ecosystem. Generally speaking, using chemical methods for water remediation can achieve immediate results in a short period of time, but it is easy to cause secondary pollution of water bodies and can only be used as a pre-treatment method for ecological restoration and emergency control technology.

[0006] Ecological-biological methods restore water quality according to natural laws, and repair polluted water bodies by strengthening the interaction between natural organisms or the self-purification ability of the water body. Mainly include: aquatic plant ecological restoration technology, ecological slope (bank) technology, microbial remediation technology.

[0007] In the aquatic plant ecological restoration technology, the use of aquatic plants as raw materials to build artificial floating islands or artificial sediment beds for water ecological restoration technology is also becoming more and more perfect.

[0008] The existing artificial floating island (or artificial floating bed) technology only has the functions of floating and convenient installation, has little effect on water flow, and cannot change the water flow, so its function is single and not good enough. SUMMARY

[0054] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0055] In practice or experiment, it is found that the flow rate of water is different, and the purification effect of the plant in the water will also be different, and this difference is in the form of a parabola, and the top of the parabola is the best purification state of the plant, and the corresponding flow rate. In the rectangular coordinate system, the abscissa is the flow rate, and the ordinate is the purification effect, so as to obtain a parabola. Therefore, the technical means of the present application is mainly how to find the best purification flow rate of the river and the aquatic plant. Since rivers are different, the aquatic plants growing around each river are different, so it is necessary to find the best purification scheme by individually adapting to each river.

[0056] In Figure 10 In the schematic diagram of the river and the detection point setting, the river C, the rest, the first detection point A1, the second detection point A2, the third detection point A3, the first river B1, the second river B2, and the like are shown in the attached Figure 10 In the attached drawings, the first river B1 and the second river B2 are respectively curved.

[0057] Please refer to Figures 1-10 The exemplary ecological rural river restoration method of the present application includes the following steps:

[0058] S10, setting an artificial floating bed to form a new turbulent flow on the surface of the river C and change the flow rate and flow direction of the surface of the river C.

[0059] In the present application, the turbulent structure on the artificial floating bed forms a new turbulent flow on the surface of the river, thereby changing the flow rate and flow direction of the surface of the river.

[0060] In some preferred embodiments, the entire artificial floating bed adopts a plastic structure, wherein the outer frame 11 is large and hollow to provide sufficient buoyancy.

[0061] In some preferred embodiments, the artificial floating bed includes an outer frame 11, an inner frame 12, a sleeve 20, a connecting rib 13, a flow guide piece 60, an arm lever 70, and an assembly buckle 80.

[0068] In some preferred embodiments, two guide vanes 60 are provided, and the two guide vanes 60 are located on the same plane.

[0069] In some preferred embodiments, the guide vane 60 is vertically placed.

[0070] The guide vane 60 in the present application forms a turbulent flow on the surface of the river, thereby changing the flow velocity and direction of the river surface. The change in water flow velocity is very important in the present application, and the formation of turbulent flow or disturbance flow is for the purpose of changing the flow velocity of the water flow, and then forming the water quality purification capacity under the flow velocity.

[0071] In the present application, the placement direction of the guide vane 60 has a great influence on the water flow, and at least four directions are formed. When a plurality of artificial floating beds are combined, more combination possibilities can be formed. Furthermore, at least four disturbance effects are formed.

[0072] In some preferred embodiments, the disturbance column 50 is further included, and a plurality of disturbance columns 50 are fixedly arranged on the lower surface of the inner frame 12, and the disturbance column 50 is vertically placed.

[0073] The indicating strip 30 is further included, and the indicating strip 30 is arranged on the upper surface of the connecting rib 13, and the indicating strip 30 is arranged correspondingly with the guide vane 60, so that the direction of the guide vane 60 can be understood through the indicating strip 30.

[0074] In the present application, the turbulence column 50 is arranged to increase the turbulence of the river surface, so as to form more turbulence on the river surface.

[0075] Due to the uniform arrangement of the turbulence column 50 and the absence of direction, the outer frame 11 has no significant difference in effect on the turbulence column 50 regardless of the angle of placement.

[0076] In some preferred embodiments, it further comprises a bottom support 90, a counterweight ball 42, and a fixed rod 41.

[0077] The bottom support 90 is installed in the middle of the innermost layer of the sleeve 20.

[0078] The counterweight ball 42 is fixedly connected with the bottom support 90 through the fixed rod 41, so that the fixed rod 41 is in the same straight line as the axis of the sleeve 20.

[0079] In the present application, the bottom support 90 is used to support plants.

[0080] In some preferred embodiments, the multiple layers of the sleeve 20 are arranged in a form of increasing height from the outside to the inside layer by layer.

[0081] The sleeve 20 is provided with a through hole to communicate the inside and outside of the sleeve 20.

[0082] In some preferred embodiments, eight arm rods 70 are provided, and the eight arm rods 70 are evenly arranged.

[0083] The assembly buckle 80 comprises a bottom plate 81, a first wedge block 82, and a second wedge block 83; the inclined surfaces of the first wedge block 82 and the second wedge block 83 are opposite to each other, and the cross-sectional area of the end of the first wedge block 82 and the second wedge block 83 close to the bottom plate 81 is small, and the cross-sectional area of the end of the first wedge block 82 and the second wedge block 83 away from the bottom plate 81 is large.

[0084] The outer frame 11 is a hollow structure, and the inner frame 12 is a solid structure; the outer frame 11, the inner frame 12, and the arm rod 70 are respectively made of plastic material, and are made of the same material.

[0085] In the present application, the working principle of the related structure of the artificial floating bed is explained as follows:

[0086] 1) Plant the plants in the innermost layer of the sleeve 20 and support them on the bottom support 90; then place the entire artificial floating bed on the river surface.

[0087] 2) Since the sleeve 20 is a multi-layer structure, and the depth of each layer is different, the depth increases layer by layer from the outside to the inside, which plays a role in protecting the growth of plants and gradually disturbing the flow.

[0088] 3), the sleeve 20 and the outer frame 11 are connected and fixed by connecting rib 13, and multiple inner frames 12 are arranged to enhance the stability and fixing effect; at the same time, compared with the prior art, the overall weight of the artificial floating bed is reduced.

[0089] 4), the spoiler column 50 arranged disturbs the flow of the river surface, and the direction and speed of the flow are changed.

[0090] 5), the through hole is opened to facilitate the water into the innermost layer of the sleeve 20, so that the water flows in and out, and the effect of purifying water quality is better; and because the through hole is small, it will not affect the growth of plants and roots.

[0091] 6), the counterweight sphere 42 plays a role in increasing the counterweight, and the counterweight sphere 42 is placed at the center position and connected and fixed by the rope or fixing rod 41; in some schemes, the counterweight sphere 42 adopts a solid sphere structure wrapped with plastic, which increases the weight and improves the stability of the floating bed.

[0092] 7), the arm rod 70 is used for connecting, supporting and stabilizing between two artificial floating beds; the assembly buckle 80 is used for connecting and fixing the two arm rods 70; the assembly buckle 80 has two wedge blocks with trapezoidal cross section, and during assembly, the opening needs to be expanded by pulling force to buckle the two wedge blocks and achieve the effect of preventing loosening. Furthermore, in the present application, the assembly buckle 80 needs to have a certain deformation ability. However, the assembly buckle 80 cannot be too soft, which cannot guarantee good assembly stability; also cannot be too hard, which is not convenient for the connection and buckling of the two assembly buckles 80.

[0093] 8), the flow guide piece 60 is used for guiding the flow of water to change the straight line direction of the water flow into the oblique direction. In this process, the direction of the water flow changes, and then the component speed of the water flow in the straight line direction also slows down.

[0094] 9), the flow guide piece 60 and the indicating strip 30 are a set of components used together, the indicating strip 30 is located above the inner frame 12, the flow guide piece 60 is located below the inner frame 12, the direction of the flow guide piece 60 corresponds to the direction of the indicating strip 30, so that the direction of the flow guide piece 60 can also be understood from above.

[0095] 10), eight direction arm rods 70 are arranged, so that there are at least two assembly methods between two artificial floating beds, as shown in the drawings. The difference between the two connection methods is that the relative positions of the two artificial floating beds are different, one is in the same horizontal direction, and one is in the oblique direction. The figure demonstrates the assembly form and state of the artificial floating bed.

[0096] S20, select the first river channel B1 and the second river channel B2 on the same river.

[0097] In some preferred embodiments, the first river channel B1 is a straight channel or a curved channel, and the second river channel B2 is a straight channel or a curved channel.

[0098] In some preferred embodiments, the first river channel B1 is a curved channel, and the second river channel B2 is a curved channel, and forms a first river bend and a second river bend.

[0099] There are two ways to form a curved channel, one is naturally existing, which can be directly selected, and the other is not naturally existing, which is artificially excavated to obtain a curved channel.

[0100] S30, placing artificial floating beds in different states in the first river channel B1 and the second river channel B2 respectively; setting a plurality of artificial floating beds in the first state on the first river channel B1; setting a plurality of artificial floating beds in the second state on the second river channel B2.

[0101] In some preferred embodiments, the connection state of two adjacent artificial floating beds includes horizontal connection and oblique connection.

[0102] The first state and the second state described in the present application respectively represent two different connection states of artificial floating beds, mainly including two aspects, one is the placement state of the flow guide piece 60, and the other is the connection state of the two artificial floating beds.

[0103] There are four placement states of the flow guide piece 60 of a single artificial floating bed, as shown in Figure 9 Then, when two artificial floating beds are connected, 4^2=16 kinds of placement states of the flow guide piece 60 can be formed, and if there are 6 artificial floating beds arranged in the same river channel, 4^6=4096 kinds of placement states of the flow guide piece 60 can be formed. One of the 4096 is selected in the first river channel B1, and another of the 4096 is selected in the second river channel B2.

[0104] The connection relationship of the two artificial floating beds has only two kinds, one is horizontal connection, and the other is oblique connection. For oblique connection, there are usually only two cases, one is located at the left rear, and the other is located at the right rear; as shown in the accompanying Figure 8 .

[0105] In the examples shown in the accompanying Figure 7 and Figure 8 , only the case that the flow guide pieces 60 of all artificial floating beds are in the same direction is demonstrated. For the connection state of the flow guide pieces 60 in different cases, the accompanying drawings do not expand the example in detail, and the accompanying drawings of different angles of the flow guide pieces 60 of a single artificial floating bed can be referred to.

[0106] S40, respectively detecting the water purification ability of the first river B1 and the second river B2; respectively detecting the water quality of the upstream of the first river B1, the first river B1 and the second river B2, the downstream of the second river B2, and calculating the water purification results of the first river B1 and the second river B2.

[0107] In some preferred embodiments, detection points are respectively arranged at the upstream of the first river B1, between the first river B1 and the second river B2, and at the downstream of the second river B2, and first detection point A1, second detection point A2 and third detection point A3 are respectively formed.

[0108] The first water quality result is obtained through the first detection point A1, the second water quality result is obtained through the second detection point A2, and the third water quality result is obtained through the third detection point A3.

[0109] The purification effect of the first river B1 is obtained by calculating the difference between the first detection point A1 and the second detection point A2.

[0110] The purification effect of the second river B2 is obtained by calculating the difference between the second detection point A2 and the third detection point A3.

[0111] The purification effects of the first river B1 and the second river B2 are compared to obtain a better solution.

[0112] S50, finding a better water purification solution; comparing the water purification ability of the first river B1 and the second river B2, if the purification effect of the first river B1 is better, the artificial floating bed is laid in the river in the first state; if the purification effect of the second river B2 is better, the artificial floating bed is laid in the river in the second state.

[0113] In some preferred embodiments, the setting directions of the plurality of guide vanes 60 are parallel, so that the turbulence directions of the plurality of artificial floating beds are the same.

[0114] Alternatively, the setting directions of the plurality of guide vanes 60 are perpendicular, so that the turbulence directions of the plurality of artificial floating beds are perpendicular.

[0115] In the technical solution of the present application, the optimal plant is aquatic plant, and the aquatic plant in the place of the river is the best. The second is other plant varieties or aquatic plants in other places.

[0116] In the present application, the sleeve 20, the guide vane 60, the turbulence column 50 and the through hole of the artificial floating bed are the most important features, which play a crucial role in the implementation of the solution and the realization of the technical effect. Because of these structures or features, they can play the role of turbulence and change the flow rate and flow direction, so that the flow rate of the river surface changes, thereby producing the purification effect under the flow rate.

[0117] The ecological rural river restoration method described in the application sets the artificial floating bed with changed turbulent flow of the river surface, and uses it in two different states; then, the artificial floating bed of the application can have at least two combined assembly ways, and can form at least two combined states, one of which is placed in the first river B1, and the other is placed in the second river B2. The combination of the artificial floating bed in each state has different effects on the change of the water flow of the river surface, or has a great influence, or has a smaller influence, so that the river flow rate under the purification state is also different. It is found through experiments that the purification effect on water quality is not the same under different flow rates. Therefore, through the technical means of the application, a better way of water quality purification can be found in two combined states, and a water quality purification combination that is more suitable for the river can be found, and the river water quality can be better purified.

[0118] Some supplementary descriptions of the effects of the ecological rural river restoration method of the application are summarized as follows:

[0119] 1) The artificial floating bed in the application is set, so as to play a role of disturbing the flow of the river surface and changing the flow direction and flow rate. Since there are two assembly connection ways of the artificial floating bed, two disturbing ways are formed, and the influence on the water flow is also different, so that the water quality purification capacity of the artificial floating bed combination in two states can be judged. The judgment is based on the river and the aquatic plants under the river, and has better adaptability and accuracy.

[0120] 2) The flow rate of each river is not the same, and the influencing factors of the local suitable aquatic plants are different, so it is necessary to find the most suitable purification method, and it is necessary to find the most suitable flow rate. Through the method of the application, the most suitable purification flow rate of the river can be found.

[0121] 3) According to the purification effect, a more suitable purification way is found, and it is used as the water quality purification scheme of the river.

[0122] 4) Through the application, a targeted river purification method can be obtained.

[0123] The above-described embodiments only express several embodiments of the application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which are within the scope of protection of the application.
