As shown in fig. 1, the method includes steps 101 to 105:
The water conservancy information comprises river flow velocity and water level, and the wind power information comprises wind power and wind speed. In addition, the water conservancy information also comprises river width, river bottom elevation data and the like.
The target river is a river in which an oil spill accident may occur. A portable integrated data monitoring and commanding mobile terminal is arranged at a preset monitoring position in a target river, so that position information, water conservancy information, wind power information and the like can be measured through the terminal. The portable integrated data monitoring and commanding mobile terminal has the functions of positioning, flow velocity water level measurement, wind speed and direction measurement and the like, and can also realize real-time reporting of monitoring data to a server, so that the data acquisition process is facilitated. When an oil spill accident exists, the portable integrated data monitoring and commanding mobile terminal can receive the emergency disposal scheme sent by the server, so that field emergency disposal personnel can conveniently carry out oil spill emergency disposal work.

Before the oil spill situation model is established, the oil spill risk assessment can be carried out on the target river to determine when and where the target river is easy to have the oil spill accident, and the nature, the oil quantity and the like of leaked oil in the oil spill accident. Wherein, the oil quality, oil quantity, etc. leaked in the oil spill accident can be determined according to the information of enterprises transporting oil in the target river. Thus, the set oil spilling parameters can better meet the actual conditions.
And 103, determining the average thickness, the area and the arrival time of an oil film when the spilled oil reaches the key section of the target emergency treatment according to the hydrodynamic model and the spilled oil scene model.
Wherein, the key section of the target emergency disposal is the position for processing the oil spill.

The target emergency disposal key section is determined according to the following method: calculating the distance between the oil spilling position and a preset emergency treatment key section; and determining a preset emergency disposal key section closest to the oil spilling position as a target emergency disposal key section.
And step 104, determining the allocation amount of the oil spilling materials according to the oil spilling parameters, the river width, the average thickness of the oil film, the area of the oil film and the arrival time.
The emergency oil spilling materials commonly used in the river oil spilling pollution accident comprise an oil containment boom, an oil collecting device, an oil absorption felt and the like, and a plurality of emergency materials are commonly operated in a coordinated mode in the emergency disposal process to achieve a good oil spilling disposal effect. In the embodiment of the application, the allocation amount of the emergency materials is calculated through the matching calculation model of the oil containment boom, the oil receiving machine and the oil absorption felt, so that the emergency disposal scheme of oil containment, oil receiving and oil absorption is determined. The methods for determining the allocation amounts of the oil containment boom, the oil collecting device and the oil absorption felt according to the oil spilling parameter, the average thickness of the oil film, the area of the oil film and the arrival time will be described respectively.
A. Oil containment boom matching calculation model
When laying the oil containment boom, the water body environment factor and the laying factor need to be considered at the same time. The distribution and control angle of the oil containment boom is mainly related to the central water flow speed of a river; the selection of the freeboard and the draft of the oil containment boom is related to the flow velocity and the depth of a river; the arrangement length and the arrangement control angle of the oil containment boom are related to the width of a river. And the necessary condition for controlling the oil containment boom is that the water depth is more than or equal to 3 times of the draft depth of the oil containment boom, otherwise, the control is invalid.
Through experiments, the enclosure control efficiency has a linear relation with the flow velocity and the draught depth of a river, and the linear relation is as follows:
η＝-569058x2+989.39x+99.971
in the formula, eta is the confining efficiency, and x is the ratio of the absolute value of the river flow velocity to the absolute value of the draught.
After the draft and the river flow rate of the oil containment boom are obtained, the containment efficiency can be calculated according to the above. If the containment efficiency of the oil containment boom is more than or equal to 95 and less than or equal to 105, the configuration length of the oil containment boom is 1.4 times of the width of a river, the distribution control angle is 45 degrees, and the distribution control mode is a single-stage flow guide mode; if the containment efficiency of the oil containment boom is more than or equal to 85 and less than or equal to 95, the preparation length of the oil containment boom is 4 times of the width of a river, the distribution control angle is 30 degrees, and the distribution control mode adopts a double-layer single-stage diversion mode; if the containment efficiency of the oil containment boom is more than or equal to 75 and less than or equal to 85, the configuration length of the oil containment boom is 6 times of the width of a river, the distribution control angle is 20 degrees, and the distribution control mode adopts a double-layer single-stage diversion mode; if the containment control efficiency of the oil containment boom is more than or equal to 45 and less than or equal to 55, the configuration length of the oil containment boom is 10 times of the width of the river, the distribution control angle is 15 degrees, the distribution control mode is a double-layer flow guide mode, the length of each layer of the first-level oil containment boom is 1.6 times of the width of the river, and three levels are continuously distributed.
The preparation length is a value calculated by multiplying a plurality of river widths, that is, a value obtained by multiplying a numerical value of the river width by a multiple, and is 1.4 × 20 to 28 meters when the river width is 20 meters and the preparation length is 1.4 times the river width.
Exemplary, specific values of river flow rate and draft, and corresponding boom configurations, are given in table one below:
watch 1
In table one, B is used to represent the multiple of the river width.
B. Oil receiving equipment matching calculation model
The allocation amount n of the oil receiving equipment can be calculated according to the following formula1：
Wherein, a1Is the oil spill in m3，b1The maximum oil recovery rate of the oil recovery equipment at the current river flow rate, c is the oil recovery amount of the oil recovery equipment in unit time, and d is the maximum oil recovery time of each oil recovery equipment.
It should be noted that the oil recovery rate is influenced by the flow velocity of the river, and the oil recovery rate is high at the still water level; the high flow velocity water body, the oil containment boom is easy to lose efficacy, the oil recovery rate is low. In the calculation model, in order to ensure sufficient recovery of the spilled oil, the usage amount of the oil recovery device is determined according to the maximum oil recovery amount (i.e. the product of the oil spilled amount and the maximum oil recovery rate of the oil recovery device at the current river flow rate).
C. Oil absorption felt matching calculation model
The type and amount of the oil absorption felt depends on the oil spill amount and the river flow rate. In the model, the oil overflow amount can be calculated through the average thickness of the oil film and the area of the oil film, and the selected amount of the oil absorption felt is reversely deduced according to the oil overflow amount.
Specifically, the oil spill volatility k can be calculated according to the following formula:
then, the preparation amount n of the oil absorption felt is calculated according to the following formula2：
Wherein, a2Is the weight of oil spill, unit is ton, H is the average thickness of oil filmS is the oil film area, b2And m is the oil absorption multiplying power of the oil absorption felt, which is the minimum oil recovery rate of the oil recovery equipment under the current river flow speed.
The weathering and migration conditions of the spilled oil in the water body are complex, and the influence of the water body is mainly great due to the flow velocity, so that the preparation amount of the oil absorption felt is determined according to the extreme conditions of the minimum volatility and the minimum oil recovery rate of the oil product in order to ensure the full recovery of the spilled oil.
And 105, determining the allocation amount of the oil spill materials required for treating the inland river oil spill as an inland river oil spill emergency disposal scheme.
Considering that the oil spilling materials need to be called from the emergency equipment warehouse of the inland river bank area, the oil spilling material calling source and the oil spilling material calling amount in the emergency equipment warehouse can be determined by combining the oil spilling material reserve amount in the inland river bank area, and the oil spilling material calling source and the oil spilling material calling amount in the emergency equipment warehouse can be used as an emergency disposal scheme.
Specifically, before determining the allocation amount of oil spill materials required for processing the oil spill of the inland river as an inland river oil spill emergency disposal scheme, acquiring the geographical position information and the oil spill material reserve amount of an oil spill emergency equipment bank arranged in an inland river bank area; and then, calculating the distance between the oil spill emergency equipment library and the target emergency disposal key section according to the geographical position information of the oil spill emergency equipment library and the position information of the target emergency disposal key section.
And if the reserve quantity of the oil spilling materials of the oil spilling emergency equipment bank closest to the target emergency handling key section is more than or equal to the allocation quantity of the oil spilling materials, predicting that the quantity of the oil spilling materials taken from the oil spilling emergency equipment bank closest to the target emergency handling key section is equal to the allocation quantity of the oil spilling materials, and determining the geographical position information of the oil spilling emergency equipment bank closest to the target emergency handling key section and the quantity of the oil spilling materials predicted to be taken from the oil spilling emergency equipment bank closest to the target emergency handling key section as the inland river oil spilling emergency handling scheme.
Illustratively, if 5 oil recovery devices are needed, and 7 oil recovery devices in the oil spill emergency device bank closest to the target emergency treatment critical section are more than 5 oil recovery devices needed, 5 oil recovery devices are determined to be called from the oil spill emergency device bank closest to the target emergency treatment critical section, and the geographical location information of the oil spill emergency device bank closest to the target emergency treatment critical section and the number of the called oil recovery devices, namely 5 oil recovery devices, are used as emergency treatment schemes.
If the reserve quantity of the oil spilling materials of the oil spilling emergency equipment storeroom closest to the target emergency handling key section is smaller than the allocation quantity of the oil spilling materials, sequentially determining the quantity of the oil spilling materials expected to be taken from each oil spilling emergency equipment storeroom according to the sequence from near to far until the quantity of the oil spilling materials expected to be taken from all the oil spilling emergency equipment storerooms is equal to the allocation quantity of the oil spilling materials, and determining the geographical position information of the oil spilling emergency equipment storeroom expected to be taken and the corresponding quantity of the oil spilling materials expected to be taken as an inland river oil spilling emergency handling scheme; and if the quantity of the needed oil spilling materials is larger than the oil spilling material reserve quantity in the oil spilling emergency equipment warehouse, the quantity of the oil spilling materials taken from the oil spilling emergency equipment warehouse is expected to be equal to the oil spilling material reserve quantity in the oil spilling emergency equipment warehouse.
Illustratively, if 5 oil recovery devices are required, and 2 oil recovery devices are required in the oil spill emergency equipment bank a closest to the target emergency handling critical section, which is less than 5 required, then in addition to the 2 oil recovery devices from the closest oil spill emergency equipment bank a, 3 oil recovery devices from a slightly further oil spill emergency equipment bank need to be called. If 4 oil receiving devices are arranged in the second nearest oil spilling emergency device library B, and more than 3 oil receiving devices are arranged in the second nearest oil spilling emergency device library B, 3 oil spilling emergency device libraries are called from the oil spilling emergency device library B; if the number of the oil receiving equipment in the second nearest oil spilling emergency equipment base B is 1 and less than 3, the number of the oil receiving equipment in the oil spilling emergency equipment base B is less than 1, the number of the oil receiving equipment in the oil spilling emergency equipment base B is less than 3, the number of the oil spilling emergency equipment base A and the number of the oil receiving equipment in the oil spilling emergency equipment base A (2), the number of the oil spilling emergency equipment base B and the number of the oil receiving equipment in the oil spilling emergency equipment base B (3) are taken as emergency disposal schemes until the number of the oil receiving equipment which can be called reaches 5.
That is, oil spilling supplies are preferably taken from the nearest emergency equipment warehouse, and if the oil spilling supplies in the nearest emergency equipment warehouse are less than the required oil spilling supplies, the oil spilling supplies are taken from the slightly distant emergency equipment warehouse, so that the oil spilling supplies are timely and in place.
In the embodiment of the application, a hydrodynamic model is established according to the conditions of water conservancy information, wind power information and the like of inland rivers, a set oil spill parameter is combined to determine the drift diffusion rule of the oil spill, namely the average thickness, the area, the arrival time and the like of the oil film when the oil spill reaches the key section of the target emergency disposal, and the allocation amount of the oil spill material is determined according to the drift diffusion rule of the oil spill, so that an inland river oil spill emergency disposal scheme is obtained, the emergency disposal scheme for determining the inland river oil spill at a higher speed is realized, and the emergency disposal process is accelerated.
