港口水域污染治理工艺改进研究
|
摘要
提出一种新型的港口水域污染治理工艺,该工艺是对活性污泥工艺、生物膜工艺的改进,它将两种工艺的优点相结合,是一种复合工艺。研究分为三部分:首先对港口水域污染情况进行简要分析;其次对治理工艺进行改进;最后对工艺改进效果进行分析验证。结果表明:与活性污泥工艺、生物膜工艺相比,利用复合工艺治理水中五种主要污染物质后,悬浮物、BOD、COD、氨氮、其它的浓度较处理之前分别降低了1.14 mg/L~(-1)、3.08 mg/L~(-1)、0.79 mg/L~(-1)、1.89 mg/L~(-1)、0.3 mg/L~(-1),且降低幅度要比活性污泥工艺、生物膜工艺大得多;由此证明了该工艺改进效果。
A new technology for pollution control in port waters is proposed. This process is an improvement on activated sludge process and biofilm process. It combines the advantages of the two processes and is a composite process. This study is divided into three parts:first, a brief analysis of the port water pollution; second, the improvement of the treatment process; finally, the effect of process improvement is analyzed and verified. The results showed that the concentrations of suspended solids, BOD, COD, ammonia nitrogen and other pollutants in the treated water were decreased by 1.14 mg/L~(-1), 3.08 mg/L~(-1), 0.79 mg/L~(-1), 1.89 mg/L~(-1) and 0.3 mg/L~(-1), respectively, compared with the activated sludge process and biofilm process. The technology of mud and biofilm is much larger, which proves the improvement effect of this process.
