摘要
对两级藻类塘与水生植物塘联用处理沈阳某重污染河流的效果进行研究.结果表明:水力停留时间(HRT)=4 d,水深0.5 m,进水中PO43--P质量浓度为0.37～0.58 mg/L、TP质量浓度为0.68～1.17 mg/L、NH 4+-N质量浓度为1.57～2.94 mg/L、COD质量浓度为72.0～98 mg/L、TN质量浓度为2.31～4.24 mg/L,通过光补偿保证每天光照时间为12 h的条件下,两级藻类塘与水生植物塘联用出水中TP质量浓度的平均值为0.16 mg/L,可以达到地表水Ⅲ类标准;出水中COD质量浓度平均值为35.4 mg/L,可以达到地表水Ⅴ类标准;出水DO质量浓度平均值为5.88 mg/L,可以达到Ⅱ类标准;出水中NH4+-N质量浓度平均值为0.66 mg/L,可以达到Ⅲ类标准;对TN的平均去除率为51.1%.
The treatment of river wastewater was studied with two-stage algal pond and aquatic pond in shenyang.The optimum operating parameters of algal pond and aquatic pond were shown in belowing：HRT=4 d,water deep 0.5 m,light application time 12 h every day,under the conditions of that influent PO3-4-P concentration is 0.37～0.58 mg/L,TP concentration is 0.68～1.17 mg/L,NH＋4-N concentration is 1.57～2.94 mg/L,COD concentration is 72.0～98 mg/L,TN concentration is 2.31～4.24 mg/L,the efluent concentrations of TP,COD,DO and NH＋4-N in the two-stage algal pond and aquatic pond were：0.16 mg/L,35.4 mg/L,5.88 mg/L and 0.66 mg/L.The removal of TN in the two-stage algal pond and aquatic pond was 51.1 %.
