Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to an ecological interception system and method. Background Art

[0002] Various pollutants are discharged directly through sewage outlets or enter rivers with rainwater runoff, causing the river water to turn black and smelly. Especially in large and medium-sized cities in developed areas of my country, the problem of black and smelly rivers has become quite prominent.

[0003] The use of biological methods to treat river sewage is a new technology that has developed rapidly in recent years. It uses the life activities of cultivated plants or cultured and inoculated microorganisms to transfer, transform and degrade pollutants in the water. However, the initially restored river ecosystem is very fragile. A large amount of pollutants can easily be discharged directly through the sewage outlet or enter the river again with rainwater runoff, quickly destroying the river ecosystem and rapidly deteriorating the water quality of the river. In addition, the drainage of sewage outlets into the river is random and uncertain, which increases the pollution load entering the river and the difficulty of river management. Summary of the invention

[0004] The purpose of the present invention is to provide an ecological interception system to solve the technical problem that the river sewage treatment system in the prior art cannot quickly respond to the randomness and uncertainty of the drainage of the sewage outlet into the river. In addition, an ecological interception method using the above ecological interception system is provided.

[0005] The present invention provides an ecological interception system, comprising a sewage monitoring device, an interception component and a dosing component arranged in sequence from upstream to downstream of a river, wherein:

[0006] The sewage monitoring device is connected to the dosing component by signal, and the sewage monitoring device is used to obtain sewage information and send a control signal to the dosing component according to the sewage information;

[0007] The interception component is used to intercept and absorb pollutants in sewage;

[0008] The dosing component is used to receive the control signal and add medicine into the sewage.

[0009] Furthermore, the sewage monitoring device includes a detector connected to the dosing component signal, the detector includes a first detection probe and a second detection probe, the first detection probe is arranged at the sewage outlet of the river channel, and the second detection probe is arranged upstream of the first detection probe.

[0010] Furthermore, the second detection probe is arranged 5m-10m upstream of the first detection probe.

[0011] Furthermore, the sewage monitoring device also includes a monitor for monitoring whether sewage is discharged from the sewage outlet, and the monitor is connected to the dosing component by signal.

[0012] Furthermore, the sewage monitoring device includes a processor, which is signal-connected to the dosing component. The processor is used to obtain the control signal according to the sewage information and send the control signal to the dosing component.

[0013] Furthermore, the interception assembly includes a filler bed and a floating bed which are sequentially arranged from upstream to downstream along the river channel.

[0014] Furthermore, the interception component also includes an oxygenation device disposed at the bottom of the floating bed, and the oxygenation device is signal-connected to the sewage monitoring device.

[0015] The present invention also provides an ecological interception method using the ecological interception system described in the above scheme, comprising:

[0016] The sewage monitoring device is arranged beside the river;

[0017] The dosing assembly is arranged beside the river;

[0018] Wirelessly connecting the sewage monitoring device to the dosing assembly;

[0019] The interception assembly is placed in sewage.

[0020] Furthermore, the sewage monitoring device is arranged beside the river, including:

[0021] The first detection probe is arranged at the sewage outlet of the river;

[0022] The second detection probe is arranged upstream of the first detection probe.

[0023] Further, when the first conductivity detected by the first detection probe and the second conductivity detected by the second detection probe satisfy the relationship: Cb≥k×Ca, the sewage monitoring device sends a control signal to the dosing component, wherein:

[0024] Ca is the first conductivity;

[0025] Cb is the second conductivity;

[0026] k is a coefficient greater than 1.

[0027] The ecological interception system and method provided by the present invention can produce the following beneficial effects:

[0028] When a large amount of pollutants are discharged into the river from the upper reaches of the river or enter the river with rainwater runoff, the sewage monitoring device can first detect the sewage to obtain sewage information. The sewage flowing through the sewage monitoring device will then pass through the interception component. The interception component can intercept and absorb pollutants in the sewage and preliminarily purify the sewage. The sewage then passes through the dosing component. When the water quality is poor, the sewage monitoring device will send a control signal to the dosing component, causing the dosing component to add medicine into the sewage and purify the sewage again.

[0029] Compared with the prior art, in the ecological interception system provided by the present invention, the sewage monitoring device, the interception component and the dosing component are arranged in sequence from upstream to downstream of the river. When the water quality is good, only the interception component can be used to intercept and absorb pollutants in the sewage. When a large amount of pollutants are discharged into the river from the upstream of the river or enter the river with rainwater runoff, since the sewage monitoring device is located upstream of the dosing component, the dosing component can respond quickly to the above situation, and timely reduce the pollution load entering the river and the difficulty of river management. The ecological interception system provided by this embodiment can adjust the management intensity according to the degree of sewage pollution, effectively reduce the management cost, and is more intelligent.

[0041] Embodiment 1:

[0042] The purpose of this embodiment is to provide an ecological interception system, such as Figure 1As shown, it includes a sewage monitoring device 1, an interception component 2 and a dosing component 3 which are arranged in sequence from upstream to downstream of the river, wherein: the sewage monitoring device 1 is signal-connected to the dosing component 3, the sewage monitoring device 1 is used to obtain sewage information and send a control signal to the dosing component 3 according to the sewage information; the interception component 2 is used to intercept and absorb pollutants in the sewage; the dosing component 3 is used to receive the control signal and add drugs to the sewage.

[0043] When a large amount of pollutants are discharged into the river from the upper reaches of the river or enter the river with rainwater runoff, the sewage monitoring device 1 can first detect the sewage to obtain sewage information. The sewage flowing through the sewage monitoring device 1 will then pass through the interception component 2. The interception component 2 can intercept and absorb pollutants in the sewage and preliminarily purify the sewage. Then the sewage passes through the dosing component 3. When the water quality is poor, the sewage monitoring device 1 will send a control signal to the dosing component 3, so that the dosing component 3 adds medicine to the sewage to purify the sewage again.

[0044] Compared with the prior art, in the ecological interception system provided by the present invention, the sewage monitoring device 1, the interception component 2 and the dosing component 3 are arranged in sequence from upstream to downstream of the river. When the water quality is good, only the interception component 2 can be used to intercept and absorb pollutants in the sewage. When a large amount of pollutants are discharged into the river from the upstream of the river or enter the river with rainwater runoff, since the sewage monitoring device 1 is located upstream of the dosing component 3, the dosing component 3 can respond quickly to the above situation, and timely reduce the pollution load entering the river and the difficulty of river management. The ecological interception system provided by this embodiment can adjust the management intensity according to the degree of sewage pollution, effectively reduce the management cost, and is more intelligent.

[0045] Furthermore, in order to enable the sewage monitoring device 1 to detect changes in water quality in the river more quickly, the sewage monitoring device 1 includes a detector 11 connected to the signal of the dosing component 3, the detector 11 includes a first detection probe 111 and a second detection probe 112, the first detection probe 111 is arranged at the sewage outlet 4 of the river, the second detection probe 112 is arranged upstream of the first detection probe 111, and the first detection probe 111 and the second detection probe 112 are used to detect the conductivity of the sewage.

[0046] When sewage is discharged from the sewage outlet 4 of the river, the first detection probe 111 can immediately detect the conductivity of the sewage at the sewage outlet 4. Since the second detection probe 112 is arranged upstream of the first detection probe 111, the second detection probe 112 can detect the conductivity of the sewage upstream of the sewage outlet in real time. When the conductivity measured by the first detection probe 111 differs too much from the conductivity measured by the second detection probe 112, it indicates that sewage is discharged from the sewage outlet 4. At this time, the detector 11 can send a control signal to the dosing component 3, so that the dosing component 3 adds medicine to the sewage. The arrangement of the first detection probe 111 and the second detection probe 112 on the detector 11 can quickly control the dosing component 3 to react when the pollutants are directly discharged through the sewage outlet 4 or enter the river again with rainwater runoff, so as to ensure that the pollutants are intercepted and removed at the first time when the water quality of the river decreases.

[0047] Furthermore, in order to enable the detector 11 to effectively judge whether sewage is discharged from the sewage outlet, the second detection probe 112 is arranged 5m-10m upstream of the first detection probe 111. The second detection probe 112 is at a certain distance from the first detection probe 111 to ensure that the sewage at the location of the second detection probe 112 will not be affected by the sewage discharged from the sewage outlet, so that the conductivity measured by the second detection probe 112 is the conductivity of the sewage under normal conditions, avoiding the judgment error of the sewage monitoring device 1 due to the second detection probe 112 being too close to the first detection probe 111.

[0048] Specifically, the second detection probe 112 is arranged at 5m, 6m, 7m, 8m, 9m or 10m upstream of the first detection probe 111. In the present embodiment, the second detection probe 112 is arranged at 8m upstream of the first detection probe 111. This ensures the accuracy of the detection result while avoiding the influence of other external factors caused by the second detection probe 112 being too far away from the first detection probe 111.

[0049] As another embodiment, the sewage monitoring device 1 may include a monitor 12 for monitoring whether sewage is discharged from the sewage outlet, and the monitor 12 is connected to the dosing component 3 by signal. The monitor 12 can monitor the sewage outlet in real time. When sewage is discharged from the sewage outlet, the monitor 12 sends a control signal to the dosing component 3 to control the dosing component 3 to add medicine to the sewage. The setting of the monitor 12 can control the dosing component 3 to dosing as soon as the sewage is discharged from the sewage outlet, and can quickly deal with the randomness and uncertainty of the drainage of the sewage outlet into the river.

[0050] It should be noted that the sewage monitoring device 1 may include only the detector 11 or the monitor 12, or the sewage monitoring device 1 may include both the detector 11 and the monitor 12. In the present embodiment, the sewage monitoring device 1 includes both the detector 11 and the monitor 12. No matter whether the detector 11 detects that sewage is discharged from the sewage outlet or the monitor 12 monitors that sewage is discharged from the sewage outlet, the sewage monitoring device 1 sends a control signal to the dosing component 3, which has double protection and improves the accuracy of the monitoring result of the sewage monitoring device 1.

[0051] Furthermore, the sewage monitoring device 1 includes a processor, which is signal-connected to the dosing component 3. The detector 11 and the monitor 12 are both electrically connected to the processor. The detector 11 and the monitor 12 are used to send the detected sewage information to the processor. When any one of the detector 11 and the monitor 12 detects that sewage is discharged from the sewage outlet, the processor sends a control signal to the dosing component 3 and sends the control signal to the dosing component 3.

[0052] Furthermore, if Figures 1 to 3 As shown, in order to enable the interception component 2 to effectively intercept pollutants, the interception component 2 may include a packing bed 21 and a floating bed 22 for carrying plants arranged in sequence from upstream to downstream of the river. The packing bed 21 is provided with biological fillers, and the biological fillers on the packing bed 21 are suspended in water. Microorganisms in the water can continuously attach and grow on the inner and outer surfaces of the biological fillers to form a biofilm, which fully contacts and decomposes the pollutants in the water, thereby achieving the purpose of purifying the water quality. The floating bed 22 can carry plants, and the roots of the plants floating in the water can adsorb and absorb organic pollutants such as ammonia, nitrogen, and phosphorus in the water, and release compounds that inhibit the growth of algae. The combined action of the packing bed 21 and the floating bed 22 can double the pollutants in the sewage and remove them, and the packing bed 21 and the floating bed 22 are located upstream of the dosing component 3, which can first remove the pollutants by biological methods, and when the water quality decreases, the dosing component 3 is used to remove them by chemical methods, so that the ecological interception system provided by this embodiment is more economical and environmentally friendly.

[0053] Specifically, Figure 3 As shown, the floating bed 22 is a hollow disc-shaped structure, and is provided with a plurality of through holes for inserting plants. The plurality of through holes are evenly arranged on the floating bed 22 so that the floating bed 22 will not tilt when plants are placed on the floating bed 22 .

[0054] Specifically, in order to make the purification effect of the biological filler better, the biological filler can adopt a composite filler. The composite filler can combine the advantages of soft materials and semi-soft fillers, and can overcome the disadvantages of both. The composite filler includes a skeleton and vinyl fibers fastened to the skeleton. The two ends of the skeleton are respectively connected to the frame on the filler bed 21, which can ensure the stability of the composite filler in the water, and the vinyl fibers are evenly distributed in the water, which is easy to form and replace membranes, and has better adaptability to sewage.

[0055] Furthermore, in order to enable the interception assembly 2 to effectively improve the water quality, the interception assembly 2 also includes an oxygenation device 23 disposed at the bottom of the floating bed 22, and the oxygenation device 23 is signal-connected to the sewage monitoring device 1. When the detector 11 or the monitor 12 in the sewage monitoring device 1 detects that sewage is discharged from the sewage outlet, the sewage monitoring device 1 sends an oxygenation signal to the oxygenation device 23, and the oxygenation device 23 adds oxygen to the sewage.

[0056] It should be noted that any device that can add oxygen to water can be the oxygenation device 23 provided in this embodiment, such as a surface aeration device, a bottom aeration device, and the like.

[0057] Preferably, the oxygenation device 23 provided in this embodiment is a bottom aeration device, and the oxygenation device 23 includes an air inlet pipe, a centrifugal pump and an air outlet pipe, wherein the air inlet pipe is placed vertically, one end of the air inlet pipe is connected to the centrifugal pump, and the other end of the air inlet pipe extends out of the water surface; the air outlet pipe is connected to the centrifugal pump. When the oxygenation device 23 is working, the centrifugal pump absorbs the gas from the air inlet pipe and discharges the gas from the air outlet pipe, so as to achieve the purpose of stirring the water body and adding oxygen to the water body at the same time.

[0058] Embodiment 2:

[0059] The purpose of this embodiment is to provide an ecological interception method using the ecological interception system provided in the above-mentioned embodiment 1, including: setting the sewage monitoring device 1 at the riverside; setting the dosing component 3 at the riverside; wirelessly connecting the sewage monitoring device 1 with the dosing component 3; and placing the interception component 2 in the sewage.

[0060] The ecological interception method provided by the present invention can detect the water quality of sewage in real time and respond quickly, reducing the difficulty of sewage treatment. Compared with the existing technology, using the ecological interception method provided by the present invention to treat river sewage can not only reduce the treatment cost, but also ensure that the treatment process is more efficient.

[0061] Furthermore, the steps of setting the sewage monitoring device 1 beside the river include: setting the first detection probe 111 at the sewage outlet of the river; and setting the second detection probe 112 upstream of the first detection probe 111. The detector 11 can effectively judge whether sewage is discharged from the sewage outlet, thereby ensuring the effectiveness of the detection.

[0062] Furthermore, in order to make the detection result of the detector 11 more accurate, when the first conductivity detected by the first detection probe 111 and the second conductivity detected by the second detection probe 112 satisfy the relationship: Cb≥k×Ca, the sewage monitoring device 1 sends a control signal to the dosing component 3, wherein: Ca is the first conductivity; Cb is the second conductivity; k is a coefficient greater than 1. The specific value of K can be selected according to the interception effect of the interception component 2 and the sewage purification effect of the dosing component 3.

[0063] In addition, the step of setting the sewage monitoring device 1 at the river bank also includes: setting the monitor 12 at the bank of the river; and wirelessly connecting the monitor 12 to the dosing component 3. When the monitor 12 detects that sewage is discharged from the sewage outlet, the dosing component 3 can be controlled to add medicine, so that the detection result of the sewage monitoring device 1 is more effective.

[0064] Furthermore, the step of placing the interception component 2 into the sewage includes: placing the packing bed 21 into the sewage; placing the floating bed 22 into the sewage. The combined action of the packing bed 21 and the floating bed 22 can effectively intercept and remove pollutants in the sewage.

[0065] In addition, in order to enable the interception component 2 to effectively improve the water quality, the step of placing the interception component 2 in the sewage also includes: arranging the oxygenation device 23 at the bottom of the floating bed 22 .

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
