水环境容量的研究，对发挥水环境容量的价值，具有一定的前瞻性和可操作性，可以节约人力、物力和财力，科学地实现水环境规划与管理。更好地服务于社会和经济的发展。水环境容量的研究，为水环境容量的科学合理有效的利用提出建设性的建议和治理措施。
釜溪河是自贡人民的“母亲河”,是自贡市的经济命脉，接纳着大量的工业废水和生活污水，导致釜溪河水环境质量常年达不到标准，因此，初步研究釜溪河的水环境容量具有十分重要的意义，也为釜溪河的水污染防治量化管理提供重要的依据。
本文对水环境容量的基础和计算模型进行了归纳和总结，在查阅、收集大量有关水环境容量的资料，对釜溪河干流河段的水环境容量进行了初步的研究，并提出了实施总量控制的建议。
首先用单因子评价法评价釜溪河干流河段的水环境质量状况，从分析结果知，釜溪河干流河段的水质状况是劣Ⅴ类，其主要的污染物是氨氮；其次，对釜溪河干流河段的污染源进行调查，确定实际的污染入河量，得出其主要的污染源为非点源污染；接着，以COD和氨氮为指标，研究选择一维水质计算模型进行计算水环境容量和允许排污量，根据实际的排污量，计算出应该削减的量，计算结果显示，釜溪河干流河段的COD和氨氮污染物要分别削减8067.12 t/a，3514.74 t/a；最后为釜溪河干流河段水环境质量的改善、水环境容量的管理以及生态流域的建设提供研究性的建议和结论。

Answer 1

The water environmental capacity's research, to displays the water environmental capacity the value, has certain foresightedness and the feasibility, may save the manpower, the physical resource and the financial resource, realizes the water environmental project and the management scientifically. Serves well social and the economical development. The water environmental capacity's research, puts forward the constructive proposal and the government measure for the water environmental capacity's science reasonable effective use. the Fuxi River is the Zigong people “the mother river”, is Zigong's economic lifeline, is admitting the massive industrial waste and the sanitary sewage, causes the Fuxi River water environment quality year to year not to be able to achieve the standard, therefore, the preliminary study Fuxi River's water environmental capacity has the very vital significance, also provides the important basis for Fuxi River's water pollution prevention quantification management. this article added water the environmental capacity foundation and the computation model has carried on the induction and the summary, in the consult, the collection massive related water environmental capacity's material, has conducted the preliminary research to the Fuxi River main current section of river's water environmental capacity, and put forward the implementation total quantity control proposal. first uses the single factor appraisal law to appraise the Fuxi River main current section of river the water environment quality condition, from the analysis result knowledge, the Fuxi River main current section of river's water quality condition is poorⅤThe kind, its main pollutant is the ammonia nitrogen; Next, carries on the investigation to the Fuxi River main current section of river's source of pollution, determined that the actual pollution into river quantity, obtains its main source of pollution for the nonpoint source pollution; Then, take COD and the ammonia nitrogen as the target, the research choice univariate water quality computation model carries on the computation water environmental capacity and the permission pollution discharge quantity, according to the actual pollution discharge quantity, calculates the quantity which should reduce, the computed result demonstrated that Fuxi River main current section of river's COD and the ammonia nitrogen pollutant must reduce 8067.12 t/a,3514.74 t/a separately; Finally for the Fuxi River main current section of river water environment quality's improvement, the water environmental capacity's management as well as the ecology basin's construction provides the investigative suggestion and the conclusion

Answer 2

Water environmental capacity of water environment capacity to play the value of certain forward-looking and maneuverability, can save manpower, material and financial resources, scientific planning and management in Water Environment. Better serve the community and economic development. Water environmental capacity for the water environmental capacity of the scientific and rational and effective use of the constructive suggestions and management measures.
Fuxi is the Zigong People's "mother river", is the economic lifeline of Zigong City, accepted a large amount of industrial wastewater and domestic sewage, causing fuxi perennial water quality not up to standard, therefore, a preliminary study fuxi of Water environmental capacity is of great significance, but also for the prevention of water pollution fuxi provide an important basis for quantitative management.
This article based on the water environment capacity and computational models are summarized and concluded in the inspection, a large number of water-related environmental capacity to collect information on fuxi River River water environmental capacity of a preliminary study and proposed implementation of the total volume control recommendations.
First, single factor evaluation on fuxi River River water environmental quality, from the analysis, we found, fuxi River water quality in rivers is inferior Ⅴ, the main pollutants are nitrogen; Secondly, kettle River River River to investigate sources of pollution, determine the actual amount of pollution into the river, that its main source of pollution for non-point source pollution; went to COD and ammonia nitrogen as indicators of the study, one-dimensional calculation model to calculate the water quality of water environment capacity and allow the volume of sewage, based on actual emissions to calculate the amount should be reduced, the results show that fuxi River reaches the COD and ammonia nitrogen pollutants were reduced to 8067.12 t / a, 3514.74 t / a; finally fuxi River to improve river water quality, water environment management and capacity building of ecological watershed research proposals and conclusions.
