【摘要】：為探索分析水體環(huán)境容量的動態(tài)特性,論文以引江濟淮工程渦河段為例,首次提出MIKE 11模型結合稀釋流量比m值法計算河流水環(huán)境容量。計算結果表明:1)基于MIKE 11模型的m值法計算環(huán)境容量來分析河流水體環(huán)境容量的動態(tài)特性是可行的,它綜合了環(huán)境管理中的總量控制和質量控制思想。2)通過對參數的合理取值,可建立客觀反映模擬河段水動力、水質時空演變規(guī)律的模型;MIKE 11模型綜合考慮河床糙度、縱向擴散系數、綜合衰減系數、地表儲水層最大含水量、土壤或根區(qū)儲水層最大含水量等因素,水深的絕對誤差(Re)、確定性系數(R2)和Nash-Suttcliffe系數Ens分別為3.30%、0.990和0.984;流量的Re、R2和Ens分別為9.8%、0.969和0.997;義門大橋斷面COD模擬誤差為13.7%,氨氮模擬誤差為14.7%。3)基于MIKE 11模型的m值法計算譙城區(qū)COD的月均環(huán)境容量為-220.48 g/s、氨氮的月均環(huán)境容量為-10.97 g/s;渦陽縣COD的月均環(huán)境容量為-17.05 g/s、氨氮的月均環(huán)境容量為2.56 g/s;蒙城縣COD的月均環(huán)境容量為30.58 g/s、氨氮的月均環(huán)境容量為4.47 g/s;懷遠縣COD的月均環(huán)境容量為176.59 g/s、氨氮的月均環(huán)境容量為10.67 g/s;與傳統(tǒng)的一維模型計算值相比,計算精度更高。結論認為,此方法可為MIKE 11模型的應用拓寬新思路,為引江濟淮工程中河流水體的動態(tài)水環(huán)境容量計算提供依據,為污染物在橫斷面均勻混合的非感潮河流水體的環(huán)境容量計算和流域水污染治理提供一種新的技術方法。
[Abstract]:In order to explore and analyze the dynamic characteristics of water environmental capacity, taking the vortex river section of Jiangjiang-Jiji-Huaihe River Project as an example, the Mike 11 model and the dilution flow ratio m method are proposed for the first time to calculate the river water environmental capacity. The results show that it is feasible to analyze the dynamic characteristics of the environmental capacity of rivers based on m-value method of MIKE11 model, which integrates the ideas of total quantity control and quality control in environmental management. It is possible to establish a model that objectively reflects the hydrodynamic force of the simulated reach and the temporal and spatial evolution law of water quality. The model of Mike 11 synthetically considers the roughness of the river bed, the longitudinal diffusion coefficient, the comprehensive attenuation coefficient, and the maximum water content of the surface water reservoir. Factors such as the maximum water content of soil or root reservoir, The absolute error (re), certainty coefficient (R2) and Nash-Suttcliffe coefficient Ens of water depth are 3.300.90 and 0.984, respectively; the remiR2 and Ens of discharge are 9.80.69 and 0.997, respectively; the error of simulating COD of section of Yimen Bridge is 13.7and the error of simulation of ammonia nitrogen is 14.7.3) the m value method based on MIKE11 model is used to calculate the error of simulating COD and ammonia nitrogen of Yimen Bridge. The average environmental capacity of COD in Qiaocheng District is -220.48 g / s, that of ammonia nitrogen is -10.97 g / s, that of COD in Guoyang County is -17.05 g / s, that of ammonia nitrogen is 2.56 g / s, that of COD in Mengcheng County is 30.58 g / s, and that of ammonia nitrogen is 30.58 g / s. The average environmental capacity of Huaiyuan County is 176.59 g / s, the average monthly environmental capacity of ammonia nitrogen is 10.67 g / s, which is compared with the traditional one-dimensional model. The accuracy of calculation is higher. The conclusion is that this method can broaden the new ideas for the application of MIKE11 model and provide the basis for the calculation of the dynamic water environment capacity of river water in Jiangjiang-Jiji-Huai project. It provides a new technical method for environmental capacity calculation and water pollution control of non-tidal river with uniform cross section mixing.
