三角模糊数方法在水环境风险评价中的应用

Application of theTriangular Fuzzy Number Method in Risk Assessment of Water Environment

为了研究丁香湖再生水回用后对丁香水源地水质带来的风险,利用三角模糊法对再生水回用后丁香湖地区水质进行风险评价,得出北部污水处理厂的出水在未来可能对丁香湖周边的水源地产生污染,使此水源地无法保证出水的安全,甚至可能使之废弃的结论。建议对污水厂出水深度处理,严格控制相应指标后再进行回用,同时加强水源地保护,尽量阻止污染物进入水源地防护区。

For studying the risk to the water sources because of article takes the triangular fuzzy number method to evaluate the risk the Dingxiang area, and concludes that the waste water from sewage around Dingxiang Lake in the future, makes the place not guarantee possibly. Therefore, the article suggests that sewage disposal factor reusing the reclaimed water of the Dingxiang Lake, the medwater in water source ce abandoned be reused after strictly controlling the relevant indexes, meanwhile, strengthening management of protection of the place to prevent con taminants into the protection zones.
