Description

Technical Field

[0001] The invention relates to the field of water pollution treatment, and in particular to an intelligent water pollution detection and treatment system. Background Art

[0002] Irrigation canals usually run through large areas of farmland to provide water for irrigation. Irrigation water flows through the canals to the end.

[0003] Finally, it will be connected to an underground river or pipe network. Currently, the irrigation canal is mainly used from April to October each year.

[0004] The water quality of irrigation canals not only affects farmland irrigation, but also other water resources. Especially in the case of underground infiltration, drainage and rainfall, excessive ammonia nitrogen concentration has become the most common water pollution problem. Once the irrigation canal is polluted, it will have a serious impact on the environment, so it is very important to monitor its water quality. For example, the master's thesis of Heilongjiang University, "Design of Irrigation Canal Water Quality Monitoring System Based on ZigBee", proposed a canal water quality monitoring system, which comprehensively monitors the canal water quality by setting the collection interval and manual monitoring cycle. However, during the six to seven months of irrigation period, this method is costly, and the monitoring cycle does not completely coincide with the time when the problem occurs.

[0005] The water channel is mainly monitored, but how to effectively deal with the pollution after it occurs is still a key issue. Since the water channel is usually flowing, once the water channel is blocked, the liquid level will rise and the water will not circulate, which will not only cause the water to stink, but also aggravate the spread of pollution. Under the condition of flowing water, how to prevent sewage from spreading to other water bodies or areas through the discharge end is a problem that needs to be solved urgently. Summary of the invention

[0006] The purpose of the present invention is to provide an intelligent water pollution detection and processing system, which combines agricultural information with the system and establishes a canal pollution water treatment system based on the factors that increase the ammonia nitrogen concentration, so that the canal water body can still be monitored and removed in a long-term polluted state, and the sewage treatment frequency can be increased to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A water pollution intelligent detection and treatment system, including a monitoring cloud, and also including a plurality of water body ammonia nitrogen detectors arranged at equal intervals from the water inlet to the water outlet along an open channel, a planting area module arranged in a farmland in an open channel irrigation coverage area, a collection start control module for controlling the water body ammonia nitrogen detector to start, and a turbulence treatment module arranged at the end of the water channel;

[0009] The acquisition start control module includes a fixed high-frequency start unit for controlling the water body ammonia nitrogen detector to start intermittently in the period from April to May and from September to October, and a fixed low-frequency start unit for controlling the water body ammonia nitrogen detector to start intermittently in the period from June to September;

[0010] The planting area module includes a fertilization recording unit and a climate recording unit, and the passive start unit controls the start of the water body ammonia nitrogen detector according to the recording time of the fertilization recording unit and the climate recording unit or after the fertilization recording unit records the fertilization, and after the climate recording unit records the raining stage and the raining stop stage;

[0011] The planting area module monitors the ammonia nitrogen collection data of the water body ammonia nitrogen detector, and sends the ammonia nitrogen collection data to the turbulence processing module after the ammonia nitrogen collection data exceeds the specified standard;

[0012] The turbulence processing module processes data through a data processor, which calculates the liquid inlet flow rate based on the liquid inlet flow unit. The water flow forms multiple turbulence zones through the turbulence unit, and controls the delivery speed of the quantitative dosing device in combination with the ammonia nitrogen collection data, and delivers the ammonia nitrogen treatment agent into the turbulence area.

[0013] As a further solution of the present invention: the turbulence treatment module also includes a liquid inlet flow rate unit, which calculates the port flow rate entering the turbulence unit. When the ratio of the total length of the turbulence unit to the port flow rate of the turbulence unit is less than 5-6min, the water reservoir arranged at the end of the turbulence treatment module is opened to temporarily store the liquid in the water reservoir and raise the liquid level of the water reservoir, and discharge the liquid to the outside through the high-level discharge pipe of the water reservoir.

[0014] As a further solution of the present invention: the water body ammonia nitrogen detector is arranged at the bottom of the open channel board bridge, the water body ammonia nitrogen detector is arranged on the bottom surface of the bridge body and is located above the liquid surface, and the water body ammonia nitrogen detector is provided with a telescopic water intake structure.

[0015] As a further scheme of the present invention: during the time period when the fixed low-frequency starting unit controls the water ammonia nitrogen detector to be turned on, after the passive starting unit is triggered to start, the fixed low-frequency starting unit is turned off, and the starting frequency of the water ammonia nitrogen detector is controlled by the fixed high-frequency starting unit until the water parameters collected by the water ammonia nitrogen detector are qualified, and then the control is switched to the fixed low-frequency starting unit.

[0016] As a further solution of the present invention: the quantitative dosing device is arranged at the water body ammonia nitrogen detector, and the planting area module closes the open channel (100) water inlet gate and the inlet gate of the turbulence treatment module according to the fertilization period recorded by the fertilization recording unit, and controls the passive start unit to start after the fertilization process recorded by the fertilization recording unit is completed, so that the collection start control module controls the water body ammonia nitrogen detector to start detection, and controls the quantitative dosing device at the water body ammonia nitrogen detector to start delivery according to the ammonia nitrogen data, and opens the gate after delivery to complete the flow operation.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention combines the planting area module with the collection start control module to match the sewage status monitoring cycle with the pollution cycle, improve the accuracy of sewage treatment, and save energy at the same time. It also utilizes the characteristics of water flow in the canal to set a turbulent area at the end, and uses the turbulent points to release removers. The flow rate is used to monitor the flow time of the water body. According to the flow rate, the sewage is temporarily retained in a reservoir or directly discharged to ensure that the ammonia nitrogen concentration entering other water bodies or underground pipe networks meets the emission standards.

DETAILED DESCRIPTION

[0025] See also Figure 1-Figure 4 : In this embodiment: it includes a monitoring cloud 4, and also includes a plurality of water body ammonia nitrogen detectors 3 arranged at equal intervals along the open channel 100 from the water inlet end to the water outlet end, and a planting area module 1 arranged in the farmland in the irrigation coverage area of ​​the open channel 100, a collection start control module 2 for controlling the start of the water body ammonia nitrogen detector 3, and a turbulence treatment module 5 arranged at the end of the canal.

[0026] In this embodiment: the monitoring cloud 4 is the monitoring station, and the water body ammonia nitrogen detector 3 is provided with a data transmission module for transmitting the ammonia nitrogen content detection parameters of the water body to the monitoring cloud 4, and the entire open channel 100 is monitored by the monitoring cloud 4. The planting area module 1 has two forms. The first is a monitoring terminal used in intelligent agriculture, which has a soil monitoring module and a data analysis module. It determines whether fertilization is needed through data analysis, and controls the drone or issues fertilization instructions when fertilization is needed. At the same time, the planting area module 1 can monitor the weather and record the rainfall problem of the weather. The climate recording unit 2 is mainly used to control the start of the water body ammonia nitrogen detector 3. Due to the long irrigation cycle, energy can be saved by controlling the opening and closing of the water body ammonia nitrogen detector 3 through the climate recording unit 2. The turbulence processing module 5 processes the irrigation channel water when the water body ammonia nitrogen detector 3 detects an abnormal state to prevent polluted water from entering the groundwater body or the pipe network to cause water pollution diffusion problems.

[0027] In the present embodiment: the collection start control module 2 includes a fixed high-frequency start unit 21 for controlling the intermittent start of the water body ammonia nitrogen detector 3 in the intervals of April-May and September-October, and a fixed low-frequency start unit 22 for controlling the intermittent start of the water body ammonia nitrogen detector 3 in June-September. The planting area module 1 includes a fertilization recording unit 11 and a climate recording unit 12. The passive start unit 23 controls the start of the water body ammonia nitrogen detector 3 according to the recording time of the fertilization recording unit 11 and the climate recording unit 12, or after the fertilization recording unit 11 records the fertilization and the climate recording unit 12 records the raining stage and the rain stopping stage.

[0028] In this embodiment: most plants have a spring fertilization period from April to May and an autumn fertilization period from September to October, and the total amount of fertilizer applied in the spring and autumn fertilization periods accounts for 60%-80% of the total amount of fertilizer applied to the entire crop. Therefore, the fixed high-frequency starting unit 21 is controlled by the time recording module, started in the spring fertilization period and the autumn fertilization period, and high-frequency collection is performed on the above two time periods in the form of high-frequency collection, with a frequency of less than 24 hours. June to September is the summer irrigation period. In this interval, due to the small amount of topdressing, low-frequency collection is adopted, and the collection frequency is in days. Since the open channel 100 crosses the entire planting area, during the irrigation process, fertilizers often fall from above, and it is easy for the fertilizers to enter the water body through the open channel 100 from above. At the same time, after fertilization, the ammonia nitrogen concentration in the soil will also increase. Affected by the osmosis effect, it is also easy to pollute the surrounding waters. In addition, after the ammonia nitrogen concentration in the soil increases, it will also be affected by the transmission of rainwater after rainfall, resulting in an increase in the ammonia nitrogen concentration in the canal. Therefore, a passive starting unit 23 is set. The passive starting unit 23 can control the water body ammonia nitrogen detector 3 to start according to the appearance of the fertilization recording unit 11 and the climate recording unit 12, or control the fixed high-frequency starting unit 21 or the fixed low-frequency starting unit 22 to start, so that the monitoring high-frequency period corresponds to the pollution period.

[0029] In this embodiment: the planting area module 1 monitors the ammonia nitrogen collection data of the water body ammonia nitrogen detector 3, and after the ammonia nitrogen collection data exceeds the specified standard, the ammonia nitrogen collection data is sent to the turbulence processing module 5, and the turbulence processing module 5 processes the data through the data processor 51, and the data processor 51 calculates the liquid inlet flow rate based on the liquid inlet flow unit 52. The water flows through the turbulence unit 55 to form a plurality of turbulent zones, and controls the delivery speed of the quantitative dosing device 54 in combination with the ammonia nitrogen collection data, and delivers the ammonia nitrogen treatment agent into the turbulent area.

[0030] In this embodiment: Since the irrigation canal is flowing water, when the water body is polluted by ammonia nitrogen, the water problem needs to be solved under flowing conditions. At present, water ammonia nitrogen remover is the most suitable method for use in irrigation canals. It only needs to be put into the water body for thorough mixing. However, in the case of long-distance flow, how to fully mix is ​​a problem. Therefore, a turbulence treatment module 5 is provided at the end of the canal. First, the data processor 51 needs to collect ammonia nitrogen parameters collected by the water ammonia nitrogen detector 3 that is closest to itself or installed at the water inlet of the turbulence treatment module 5, and record the inlet flow of the turbulence treatment module 5 through the liquid inlet flow unit 52, and carry out orderly delivery according to the flow control quantitative dosing device 54. Please refer to Figure 4When the liquid passes through the turbulent unit 55, the middle flow channel is affected by the reverse force of the flow channels on both sides to form turbulence in the staggered area, and the turbulent treatment module 5 is located above the turbulent part to release the remover. The complex turbulent fluid direction promotes the remover to mix fully with the water body and flow backward. The number of turbulent units 55 can be set to multiple, and the liquid flow rate will also decrease in the turbulent area. By increasing the number of turbulent units 55, the time for the water body to pass through the turbulent unit 55 can be controlled to 5-6 minutes. At this stage, the remover reacts completely, and the liquid ammonia nitrogen concentration is reduced and then discharged, so as not to pollute the environment.

[0031] In this embodiment: the turbulence treatment module 5 also includes a liquid inlet flow rate unit 53, which calculates the port flow rate entering the turbulence unit 55. When the total length of the turbulence unit 55 and the port flow rate of the turbulence unit 55 are less than 5-6min, the water reservoir 6 arranged at the end of the turbulence treatment module 5 is opened to temporarily store the liquid in the water reservoir 6 and increase the liquid level of the water reservoir 6, and discharge the liquid to the outside through the high-level discharge pipe of the water reservoir 6.

[0032] In this embodiment: the liquid inlet flow rate unit 53 can be set at multiple turbulence units 55, or at the inlet and outlet of the turbulence unit 55, and the residual time of the live water in the turbulence unit 55 is obtained by combining the flow rate difference with the length. When the flow rate of the liquid inlet flow rate unit 53 is too fast, it means that the removal agent is not completely reacted. For the precipitation type removal agent, the sediment will also be put into other water bodies or pipe networks. Therefore, a reservoir 6 is set up. The reservoir 6 can precipitate substances on the one hand, and can play a buffering role on the other hand. In the case of rainfall, when the water flow is large, it plays an emergency treatment role.

[0033] In this embodiment: the water body ammonia nitrogen detector 3 is arranged at the bottom of the board bridge 200, the water body ammonia nitrogen detector 3 is arranged on the bottom surface of the bridge body and is located above the liquid surface, and the water body ammonia nitrogen detector 3 is provided with a telescopic water intake structure.

[0034] In this embodiment: in order to avoid the problem of bacteria breeding caused by the water intake structure being distributed in the water body for a long time, the water intake mechanism is normally located above the liquid surface, and the water intake mechanism of the water body ammonia nitrogen detector 3 is controlled to go deep into the water body to take water when necessary. In order to meet the needs of personnel passage, multiple equidistant board bridges 200 are set for convenient passage, so the board bridge 200 can be used as the installation area of ​​the water body ammonia nitrogen detector 3.

[0035] In the present embodiment: during the time period when the fixed low-frequency starting unit 22 controls the water body ammonia nitrogen detector 3 to be turned on, after the passive starting unit 23 is triggered to start, the fixed low-frequency starting unit 22 is turned off, and the starting frequency of the water body ammonia nitrogen detector 3 is controlled by the fixed high-frequency starting unit 21 until the water body parameters collected by the water body ammonia nitrogen detector 3 are qualified, and then the control is switched to the fixed low-frequency starting unit 22.

[0036] In the present embodiment: when the fixed low-frequency starting unit 22 controls the water body ammonia nitrogen detector 3 to be in the low-frequency stage, it does not mean that the ammonia nitrogen concentration in the water body will not exceed the standard, because fertilization will also be carried out during the control of the fixed low-frequency starting unit 22, but the amount of fertilizer applied is small. Therefore, after fertilization, when the water body ammonia nitrogen detector 3 is turned on by the passive starting unit 23, after detecting that the ammonia nitrogen concentration in the water body is higher than the set concentration, it will trigger the subsequent sewage treatment process, but there is still a risk. Therefore, a fixed high-frequency starting unit 21 is used to control the water body ammonia nitrogen detector 3 to start at high frequency to monitor the water body until the ammonia nitrogen concentration in the water body decreases.

[0037] In the present embodiment: a quantitative dispenser 54 is provided at the water body ammonia nitrogen detector 3, and the planting area module 1 closes the water inlet gate of the open channel 100 and the inlet gate of the turbulence treatment module 5 according to the fertilization period recorded by the fertilization recording unit 11, and controls the passive start unit 23 to start after the fertilization process recorded by the fertilization recording unit 11 is completed, so that the collection start control module 2 controls the water body ammonia nitrogen detector 3 to start detection, and controls the quantitative dispenser 54 at the water body ammonia nitrogen detector 3 to start delivery according to the ammonia nitrogen data, and opens the gate after delivery to complete the flow operation.

[0038] In this embodiment: canals are often used in large-scale planting areas, with various types of crops in multiple areas. Different crops grow in different areas and have different habits. Therefore, in order to avoid the problem of local water bodies polluting a certain section of the canal and not being treated until the water reaches the end, a quantitative dosing device 54 is also synchronously set at the water ammonia nitrogen detector 3. During the monitoring stage, when there is a problem with the quality of a certain section of the water body, the quantitative dosing device 54 at the rear section can be opened for dosing, thereby preventing the water body from affecting the rear area.

[0039] In this embodiment: when the ammonia nitrogen detectors 3 in multiple sections of the open channel 100 detect high concentrations of ammonia nitrogen, the water inlet gate of the open channel 100 and the inlet gate of the turbulence treatment module 5 can be closed, and the quantitative dosing device 54 under the board bridge 200 can be used to do the dosing, so that the water body is allowed to stand for 5 minutes to fully react before being discharged to the tail end.

[0040] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
