中文摘要:
      为了使底洞沟入嘉陵江断面水质达标,通过现场勘查、资料收集和野外同步监测,构建一维非恒定流数学模型,耦合Thomas算法,对底洞沟的水环境现状进行研究。结果表明:构建的模型拟合精度高,计算结果可靠;底洞沟水体主要超标因子为氨氮和总磷,氨氮、总磷入河量分别为43.1、3.9 t/a;在污染源构成方面,城镇生活源对污染物入河量的贡献最大,达76.5%;在空间位置方面,上游的贡献最大,占比达92%;底洞沟的氨氮、总磷水环境容量分别为16.3、2.2 t/a。建议对流域内污水管网进行整治,提高污水接管率,减少污染负荷,使入嘉陵江断面水质稳定达标。
英文摘要:
      In order to investigate the water quality status of the cross section of Didonggou River to Jialing River, a one-dimensional unsteady flow model coupled with Thomas algorithm was constructed to study the current situation of water environment in Didonggou River based on in situ investigation, data collection and field synchronous monitoring. The results show that the main indicators that exceeded the required standards were NH3—N and TP; the proposed model exhibited excellent performance with high precision and reliable prediction results; the amount of NH3—N and TP pollution discharge to Jialing River were 43.1 t/a and 3.9 t/a, respectively; according to the analysis of the composition of pollution sources, about 76.5% of the pollution load was contributed by the urban sewage; from the spatial perspective, over 92% of the pollution load came from the upstream; the water environmental capacity of Didonggou River for NH3—N and TP are 16.3 t/a and 2.2 t/a, respectively. It is suggested that control measures such as repairing the sewage pipe network in the Didonggou River Basin, improving the rate of piped sewage and reducing pollution load should be implemented, so as to make the water quality of the Didonggou to Jialing River section reach the required standard.
