摘要
将污水排放口污染物质的实测值与河流中同种物质的量，通过各河段推求的参数Ki建立起数学关系．利用这种数学模型来预测和模拟河流各河段的各种污染物质量，这是当前流域水质管理和污染治理规划是经济适用的办法．
The pollution of the interior rivers in Xinjiang is serious due to their poor self-pudrication, especially for the small streams. Water quality control of the rivers and the harnessing planning of the watershed pollution are the major subjects for the personnel of environmental protection and water resources management. The detection and simulation of the water quality of the Shuimo River basin, Urumqi, have been carried out by using some mathematic models.The Shuimo river is located at the eastern suburbs of Urumqi, and mainly fed by springs. Its annual runoff volume is 36 million m3, daily discharge 1.16 m3 / s, and total length of the channel 13.65 km. Totally 65 factories have been built along the both river banks with an annual waste water discharge of 10 million m3. The ration of the waste water and stream water is up to 30% in the river, the stream water is polluted seriously. In this study, the river is divided into 8 river sections and 9 survey sections so as to observe the hydrologic and water quality scenarios of the river and discharging outlets of waste water.The matrix equations are established through a mathemahcal inference.Oconnor model was adopted for L1i, LNliand Oli, the model parameters were calculated with concurrent eshmated values, and the model software was worked out. The methods can be used for water quality detection and control of rivers, which have significant application and economic values.
