In order to explain the technical solution of the present application, the following description is given by way of specific examples.
Referring to fig. 1, a flowchart of an auxiliary treatment method for river channel rainfall water quality reaching standards provided by the embodiment of the application is shown.
in the embodiment of the application, the water environment capacity of the river channel needs to be determined according to the inflow flow of the initial section of the river channel, the actual water quality concentration of the section on the river channel, the rainfall runoff, the target water quality concentration, the volume of the river channel and the comprehensive attenuation coefficient, and a calculation formula of the water environment capacity of the river channel can be expressed as the following equation:
W＝Q 0 (C S -C 0 )×86.4+qC S ×86.4+KVC S ×0.001
wherein W refers to the water environment capacity of the river channel; c 0 The actual water quality concentration of the upper section of the river channel is indicated; c S The water quality of the river reaches the target concentration; k is the comprehensive attenuation coefficient; q 0 The method refers to inflow flow of an initial section of a river channel; q is rainfall runoff; v means the river water volume.
It should be noted that the calculation of the watercourse water environment capacity may be further determined by other means.
In the examples of the present application, COD, TP, TN and NH were selected 3 N is used as an index of main pollutants for evaluating the water environment capacity. Setting a water quality standard-reaching target of a riverway as surface water IV-class water indexes, wherein the indexes of pollutants are respectively as follows: COD less than or equal to 30mg/L, NH 3 N is less than or equal to 1.5mg/L, TN is less than or equal to 1.5mg/L, and TP is less than or equal to 0.3mg/L. In other embodiments of the present application, the water quality compliance target of the river channel may be set to other levels, such as surface water class iii water index, etc.
It should be noted that, in the embodiment of the present application, a method for controlling the total amount of pollution load of the river is adopted, that is, in a selected river range, it is ensured that the water quality of the river generally meets the requirement, rather than that the water quality of each river section or each time reaches the set water quality target.
Specifically, through regarding the river course as a whole, after rainfall runoff pollution load volume gets into the river course, if river course total quality of water can satisfy the processing requirement up to standard, compare traditional pollutant concentration control method, but this application reducible engineering investment and control cost.
In the embodiment of the present application, regarding the determination of the rainfall runoff, it is necessary to obtain area distribution data of each underlying surface in a set area, and reasonably set the runoff coefficient of each underlying surface, and a calculation formula for the rainfall runoff can be expressed as the following equation:
illustratively, the underlying surface within the defined area includes buildings, roads, greenbelts, and bodies of water, the definitionThe coefficients of the underlying surfaces are respectively 0.75, 0.9, 0.15 and 1, the comprehensive runoff coefficient is 0.37 calculated according to the area proportion of each underlying surface, the set area is 4937.78 hectare, the rainfall is 44.7mm, the runoff time is 1 day, and the rainfall runoff is 9.45m calculated according to the formula 3 /s。
In order to simplify the calculation, in the water quality model, the physical degradation, chemical degradation and biological degradation of pollutants in the water environment are generalized into a comprehensive attenuation coefficient, in the embodiment of the application, the comprehensive attenuation coefficient of COD is set to be 0.15l/d, and NH is set to be NH 3 N is 0.12l/d, TN is 0.008l/d, and TP is 0.1l/d.
In order to ensure that the riverway water quality target is realized and the uncertainty in the calculation is coped with, a certain safety margin needs to be considered in the calculation of the water environment capacity, and the safety coefficient is 0.8 in the embodiment of the application.
Illustratively, taking the calculation of the water environment capacity of the COD in the river channel as an example, the initial concentration of the COD in the river channel is 26.6mg/L, the target concentration is 30mg/L, the comprehensive attenuation coefficient is 0.15, and the safety coefficient is 0.8, and the water environment capacity of the COD in the river channel is 28457.68kg/d according to the calculation formula of the water environment capacity. For NH in river channel 3 The calculation of the water environment capacity of-N, TN and TP can be referred to the above manner.
It should be noted that, in the embodiments of the present application, the water quality conditions of the river in the set area are divided into four types: the first type is that the water quality standard reaching rate of the riverway before rainfall and after rainfall is less than a first preset value; the second type is that the standard-reaching rate of the river channel water quality before rainfall is between a first preset value and a second preset value; the third type is that the standard reaching rate of the river water quality before rainfall is greater than a second preset value, and the river water quality after rainfall does not reach the standard; the fourth type is that the river water quality before and after rainfall reaches the standard.
Illustratively, in the embodiment of the application, the first type of the river water quality condition is that the standard reaching rate of the river water quality before and after rainfall is less than 30%; the second type is that the water quality standard-reaching rate of the riverway before rainfall is between 30% and 70%; the third category is that the standard reaching rate of the river water quality before rainfall is more than 70 percent, and the river water quality after rainfall does not reach the standard; the fourth type is that the water quality standard-reaching rate of the riverway before rainfall and after rainfall is 100 percent.
It should be noted that the river channel rainfall water quality standard-reaching auxiliary treatment method provided by the embodiment of the application mainly aims at river channels with river channel water quality conditions of the third category, namely river channels with river channel water quality standard-reaching rate of more than 70% before rainfall and river channel water quality not reaching the standard after rainfall.
In the embodiment of the application, aiming at the determination of rainfall runoff pollution load, the selected rainfall field in the set area needs to be monitored, the monitoring distribution points comprise the underlying surfaces such as building roofs, roads, greenbelts and river cross sections, and the COD, TP, TN and NH of the underlying surfaces are mainly monitored in the whole rainfall process 3 And N, simulating the concentration change of the pollutants entering the river according to the model, and calculating the rainfall runoff pollution load after fully considering the material balance relation of water quantity and water quality.
It should be understood that in any rainfall induced surface runoff process, the concentration of pollutants in runoff can be calculated by using the concept of "runoff mean concentration EMC (event mean concentration)" because random changes of rainfall intensity can cause the concentration of pollutants in runoff to change in an order of magnitude with time, and the calculation formula of EMC can be expressed as the following equation:
wherein M refers to the total amount of certain pollutants discharged by rainfall runoff; v is the total surface runoff volume caused by a certain rainfall; ct refers to the instantaneous concentration of a contaminant at t; qt is the runoff drainage at t of surface runoff; t refers to the total duration of a certain rainfall.
Therefore, the calculation formula of the rainfall runoff pollution load capacity of the whole rainfall process can be expressed as the following equation:
in the embodiment of the application, for the selection of the rainfall field, one of the rainfall fields needs to be selected from multiple rainfall fields in a set area within a preset time period, and the rainfall runoff pollution load amount is determined based on the rainfall runoff amount, the rainfall runoff discharge pollutant concentration and the total rainfall duration of the whole rainfall process corresponding to the selected rainfall field.
It should be noted that the method for selecting a rainfall event includes: determining a first preset value of the dry period duration before rainfall and a second preset value of the rainfall in the whole rainfall process according to the pollutant increment in the unit time period of the set area, and selecting the rainfall events according with the first preset value and the second preset value.
It can be understood that, for example, in the first heavy rain in spring, after long-term drying in winter, no rain exists, a large amount of pollutants are accumulated on the underlying surface of the set area, and at the moment, the rainfall runoff pollution load formed by rainfall with large rainfall is large, so that the water quality of the river channel is easy to fluctuate, even the water quality is not up to standard, and therefore, a rainfall field with long dry period time and meeting the heavy rain rainfall level is selected to have a certain reference value.
Illustratively, within the set region of the embodiment of the present application, a rainfall event is selected in which the length of the dry period before rainfall in summer is not less than 14 days and the rainfall is between 25mm/d and 50mm/d during the whole rainfall period.
Illustratively, in the setting area of the embodiment of the application, a rainfall field with the dry period duration more than 7 days before rainfall in summer and the rainfall exceeding 50mm/d in the whole rainfall process is selected.
Illustratively, in the setting area of the embodiment of the application, the rainfall field with the dry period duration more than 14 days before the non-summer rainfall and the rainfall between 25mm/d and 50mm/d in the whole rainfall process is selected.
In the embodiment of the present application, the calculation formula of the pollution load reduction amount of the river channel may be expressed as the following equation:
pollution load reduction = rainfall runoff pollution load-water environment capacity
For example, the rainfall runoff pollution load amount corresponding to the selected rainfall field in the set area is calculated, the water environment capacity corresponding to the set water quality target of the river water quality recovery in the preset time range is calculated, and the pollution load reduction amount of the river is calculated according to the calculation formula.
Specifically, the preset time range corresponding to the restoration of the river water quality to the set water quality target can be set to 24h, 48h or 72h, and the corresponding pollution load reduction treatment measures can meet the treatment requirements.
It should be noted that the maximum pollution load reduction amount needs to be obtained by selecting the maximum pollution load reduction amount corresponding to each water quality index in the river after rainfall.
Illustratively, COD, TP, TN and NH in the set area can be obtained by the calculation of the formula 3 And (4) the pollution load reduction amount corresponding to the N is compared numerically to determine the maximum value, namely the maximum pollution load reduction amount of the river channel.
And 102, determining the accumulated amount of the rainfall runoff to be treated corresponding to the maximum pollution load reduction amount according to a corresponding relation model between the accumulated amount of the rainfall runoff and the corresponding pollution load reduction accumulated amount, so as to utilize the accumulated amount of the rainfall runoff to be treated to perform standard reaching auxiliary treatment on the accumulated rainfall to be treated.
It should be noted that, in the process of surface runoff caused by any rainfall, because the random change of rainfall intensity can cause the concentration of pollutants in the runoff to change in order of magnitude with time, in the whole rainfall process of the rainfall session selected in the embodiment of the present application, a certain corresponding relationship exists between the rainfall runoff cumulative amount and the rainfall runoff pollution load cumulative amount, and further, through the corresponding relationship between the rainfall runoff pollution load cumulative amount and the rainfall runoff pollution load amount and the corresponding relationship between the rainfall runoff pollution load amount and the pollution load reduction amount, a certain corresponding relationship exists between the rainfall runoff cumulative amount and the pollution load reduction amount.
In addition, because the rainfall runoff cumulative amount corresponds to the rainfall runoff cumulative percentage one by one, and the rainfall runoff pollution load cumulative amount corresponds to the rainfall runoff pollution load cumulative percentage one by one, in the whole rainfall process of the rainfall field selected in the embodiment of the application, a certain corresponding relation exists between the rainfall runoff cumulative percentage and the rainfall runoff pollution load cumulative percentage.
Taking the pollution load reduction amount corresponding to the COD as the maximum pollution load reduction amount of the river as an example, referring to fig. 2 and fig. 3, a corresponding relationship graph between the rainfall runoff pollution load accumulation percentage and the rainfall runoff accumulation percentage corresponding to the building roof and the road surface is respectively established.
Illustratively, according to calculation, the rainfall runoff pollution load amount corresponding to the COD is 30035.77kg/d, the water environment capacity of the river channel is 28457.68kg/d, so the corresponding maximum pollution load reduction amount is 1578.09kg/d, and the ratio of the rainfall runoff pollution load amount corresponding to the COD is 5.25%, and therefore, the rainfall runoff accumulation amount corresponding to the rainfall runoff pollution load accumulation percentage of 5.25% needs to be controlled.
According to the corresponding relation in fig. 2, it can be obtained that, for the roof, the rainfall runoff cumulative percentage corresponding to the rainfall runoff pollution load cumulative percentage of 5.25% is 2.49%, and the rainfall amount is 44.7mm, so the rainfall runoff cumulative amount is 1.11mm; according to the corresponding relation in fig. 3, it can be obtained that, for the road surface, the rainfall runoff cumulative percentage is 4.21% corresponding to the rainfall runoff pollution load cumulative percentage of 5.25%, and the corresponding rainfall runoff cumulative amount is 1.88mm. Since the area ratio of the roof to the road surface is 0.66 and 0.34 respectively, the rainfall runoff cumulative amount obtained by weighted average calculation is 1.37mm, and thus the rainfall runoff cumulative amount required to be reduced and controlled is the rainfall amount of the first 1.37 mm.
It should be noted that, in the embodiments of the present application, the maximum pollution load reduction is achieved by mainly processing the rainfall runoff pollution load of the roof and the road surface in the underlying surface, and in other embodiments of the present application, it is also considered to increase the rainfall runoff pollution load of the grassland and the water body to achieve the maximum pollution load reduction, so as to ensure that the rainfall water quality of the river reaches the standard.
In addition, after determining the rainfall runoff accumulation amount to be reduced, technicians in the field can select engineering measures for reducing rainfall runoff according to local conditions according to relevant conditions of a set area where a river channel is located, and can adopt various measures for controlling sources, processes, tail ends and the like for treatment.
