应用生态土壤深度处理技术脱氮除磷的研究

Phosphorus and nitrogen removal with ecologic soil deep treatment process

介绍了生态土壤深度处理技术的结构、技术要求和净化机理。试验和工程实例研究表明,该技术对生活污水具有良好的净化效果,对NH3-N,TP,CODcr,BOD5和SS的去除率分别达到87.4%,91.5%,87.9%,92.8%和94.9%,尤其脱氮除磷效果优于一般二级处理。

The structure, technology requirement and purification mechanism of ecology soil deep treatment process was introduced. An experiment and example were carried out to assess the efficiency of this process to treat sewage wastewater and favorable treatment effects were achieved. The removing ratio of NH3-N, TP, COD(cr), BOD5 and SS was 87.4%,91.5%,87.9%,92.8% and 94.9% respectively.Especially it has excellent capbility to removal phosphorus and nitrogen.
