摘　　要：为了解决低污染水体的治理问题,本文以山东省烟台市某水系生态环境治理工程为研究对象,通过现场采样分析方法,研究了水体中污染物及各形态磷的特征及空间分布,并运用多级生态塘工艺进行了水体恢复治理。结果表明,各污染物的空间分布表现为显著的空间变异性,在组成特征上,总磷(TP)的质量浓度在全水系的分布最多;各形态磷的空间分布也表现出明显的空间变异性,在组成特征上,铁磷(Fe-P)的质量浓度最大,有机物磷(OP)的质量浓度最小;用多级生态塘处理工艺,可以大幅度地降低水体中的化学需氧量(COD)、五日生化需氧量(BOD5)、铵态氮(NH4+-N)和总磷(TP),去除率达到80%以上。In order to solve the problem of low pollution water treatment,this paper takes a river system ecological environment treatment project in Yantai City,Shandong Province as the research object,through on-site sampling and analysis methods,studies the characteristics and spatial distribution of pollutants and phosphorus forms in the water body,and uses the multi-stage ecological pond process to restore the water body.The results showed that the spatial distribution of various pollutants showed significant spatial variability,and in terms of composition characteristics,the mass concentration of total phosphorus(TP)was the most distributed in the entire water system;the spatial distribution of various forms of phosphorus also exhibits significant spatial variability,and in terms of composition characteristics,the mass concentration of iron phosphorus(Fe-P)is the highest,while the mass concentration of organic phosphorus(OP)is the lowest;multi-stage ecological pond treatment process can significantly reduce chemical oxygen demand(COD),five-day biochemical oxygen demand(BOD5),ammonium nitrogen(NH4+-N)and total phosphorus(TP)in the water body,with a removal rate of more than 80%.
