The response of Typha wetland capable of decreasing contamination has been examined indoor laboratory.According to the pilot researches,the effects of Typha wetland and hydraulic retention time in the purification efficiency for highly salty reused water treatment in TEDA Landscape River were studied in this paper,while different kinds of contamination is evaluated.The results showed that the highly salty reused water purifying efficiencies for COD,TN,NH3-N,NO3-N,TP and PO4-P were significantly different...

The response of Typha wetland capable of decreasing contamination has been examined indoor laboratory.According to the pilot researches,the effects of Typha wetland and hydraulic retention time in the purification efficiency for highly salty reused water treatment in TEDA Landscape River were studied in this paper,while different kinds of contamination is evaluated.The results showed that the highly salty reused water purifying efficiencies for COD,TN,NH3-N,NO3-N,TP and PO4-P were significantly different with hydraulic retention time.Moreover,the removal ratio of COD was in a range of from 10.00% to 44.89%,TN was from 17.20% to 71.00%,NH3-N was from 30.28% to 74.06%,NO3-N was from 18.00% to 74.00%,TP was from 62.98% to 90.01%,PO4-P was from 64.99% to 92.01%;TDS from 3 900 mg·L-1 to 4 800 mg·L-1,respectively,which was not effected on purifying efficiencies for water quality and Typha vegetation.pH of Typha wetland for water treatment was smaller than empty wetland,however.Under the combination function of absorbability and decomposition of Typha roots and microbiology,the water qualities of treatment wetland with Typha were better than without the vegetation.It was suggested that it was possible to control contaminations of the water body by means of the planting the Typha in light of research results.Furthermore,the results of this investigation may be basis and technological references for operators to restrain the eutrophication in TEDA Landscape River body.

通过香蒲湿地对天津泰达景观河道水体污染物去除的室内试验,研究了香蒲湿地对泰达高含盐再生水的净化效果以及水力停留时间对水质净化效果的影响,考察了不同污染物的去除情况。结果表明,水力停留时间对水体中COD、TN、NH3-N、NO3-N、TP、PO4-P的净化效果有明显的影响,各主要污染物随HRT的变化范围如下:COD去除率10.00% ̄44.89%;TN的去除率为17.20% ̄71.00%、NH3-N的去除率为30.28% ̄74.06%、NO3-N的去除率为18.00% ̄74.00%、TP的去除率为62.98% ̄90.01%、PO4-P的去除率为64.99% ̄92.01%,TDS在3900 ̄4800mg.L-1范围内变化对香蒲及其水处理系统净化效果没有影响,香蒲湿地pH值均比空白湿地低。由于香蒲根系具有吸收与分解污染物质的作用,在水体中种植香蒲能明显改善水质净化效果。在此基础上,通过种植香蒲,对泰达景观河道水体污染物去除收到明显的效果,同时为防治泰达再生水景观河道水体富营养化提供了理论依据和技术指导。
