基于RAGA-PPCE模型的滨州市流域水质综合评价

Comprehensive Evaluation of Water Quality in Binzhou Basin Based on RAGA-PPCE Model

以山东省滨州市重点流域水质为例,采用RAGA-PPCE模型对水质进行综合评价。选取对水体影响较大的pH、化学需氧量(COD)、总磷(TP)、总氮(TN)、氨氮(NH3-N)、溶解氧(DO)6项水质评价因子,构造水质综合评价分级标准。结果表明:RAGA-PPCE模型水质评价结果与模糊综合法评价结果基本相同;RAGA-PPCE模型评价结果客观、合理,能够有效应用于水质综合评价。

Taking key river water quality in Binzhou City of Shandong Province as an example, comprehensive evaluation of water quality with RAGA-PPCE model was conducted. Selecting 6 water quality evaluation factors including pH, dissolved oxygen, total phosphorus, total nitrogen, ammonia nitrogen, dissolved oxygen, comprehensive evaluation of water quality classification standard was constructed. The results showed that RAGA-PPCE model water quality evaluation results and fuzzy comprehensive evaluation results are basically the same. The evaluation result of RAGA-PPCE model was objective and reasonable, and it can be applied to comprehensive evaluation of water quality.
