摘　　要：泰达污水处理厂的二级处理出水(TDS为7 000～18 000 mg/L)经微滤膜工艺深度处理后被用作人工景观河道的补水,为达到减少富营养化和保持水体水质的目的,应用芦苇、三棱草、香蒲、川蔓藻等挺水、沉水植物对其进行生物、生态强化处理。结果表明:河道进水总磷和磷酸盐浓度分别为0.09～4.87 mg/L和0.09～4.83 mg/L,出水平均浓度分别为0.26、0.12 mg/L;进水总氮浓度最低时仅为0.72 mg/L,最高时达到36.69 mg/L,但大多在20 mg/L以下(约占采样次数的87%),出水值基本保持在3 mg/L以下,去除率大多在80%左右,有效地降低了水体的富营养化。可见,高含盐量的污水厂二级出水经深度处理后用作景观水体的主要补充水源是可行的,但要与相适应的植物一起构建一个健康的水体环境。Secondary effluent of TEDA WWTP （TDS 7 000 mg/L to 18 000 rag/L） was used as the additional water in the artificial landscape river after advanced treatment by MF. To reduce eutrophi- cation and keep high water quality, emergent and submerged plants such as Phragmites communis, Scir- pus planiculmis, Typha angustifolia and Ruppia maritima were used for enhanced biological and ecologi- cal treatment of the river water. The results showed that when the concentrations of TP and phosphate in the influent were 0.09 to 4.87 mg/L and 0.09 to 4.83 mg/L, respectively, the average effluent concen- trations were 0.26 mg/L and 0.12 rag/L, respectively. The influent TN concentration was at least 0.72 mg/L and at most 36.69 mg/L, but mostly below 20 mg/L （accounting for 87% of the sampled data）. The effluent TN was below 3 mg/L, and the removal rate was about 80%. In conclusion, it was feasible to use secondary effluent with high salinity as additional water in the artificial landscape river after ad- vanced treatment, but a healthy water environment with suitable plants should be created.
