【摘要】 针对不同地区的地表水、生活污水和工业废水的TOC和COD进行了测试,对测定值进行线性回归分析。结果表明,不同类型的水体其TOC与COD均具有一定的相关性,尤其是生活污水和工业废水,TOC与COD相关性比较显著,在一定条件下可由测定的TOC值推算出COD值。更多还原

【Abstract】 The value of TOC and COD in surface water,municipal sewage and industrial sewage in different regions is measured,and the results is analyzed by linear regression statistics.It is tested that TOC has a very good correlation with COD,and can be used as a continuous and cheap parameter for rapid estimation of COD in certain condition or as a control index of organic pollution especially for the municipal sewage and industrial sewage.更多还原
