摘要
通过大量实地调查、取样、室内样品分析及对开-孔河不同区段、不同时段纳污量的计算,从定量指标上反映各排污口允许排入开-孔河的污水数量。计算表明,开都河各河段水质较孔雀河好,有一定的纳污能力,并由上游至中下游递增;孔雀河段最大允许纳污量由上游至下游逐渐减少,至下游末端由于水质恶化,纳污能力已基本丧失,最大允许纳污量为零,应该严格控制排污。
Based on the large amounts of field investigation, sampling, analysis and calculation of the pollutantholding capability of the Kaidu and Kongque Rivers at their different sections and in the different periods, the maximum allowable volumes (MAV)of all the farmland sewage outlets are calculated. The results shows that the water quality of the Kaidu River is better than that of the Kongque River. The Kaidu River has some pollutantholding capability, but the MAV of pollution of the Kongque River is zero, so only taking some effective measures can the water quality of Kongque River be improved.
