摘要
通过对天津经济技术开发区泰达再生高盐水景观河道生态修复工程实际水体水质变化情况进行研究,分析了滨海盐碱地区高盐再生水景观河道水体生态修复工程的水质净化效果以及河道盐份动态变化规律。研究结果表明:水体中主要污染物COD浓度在54.15～94.15mg/L范围内变化,几乎没有去除;氮磷净化效果非常明显,它们的最大去除率分别为TN69.35%、NH3-N50.75%、NO3--N71.89%、TP56.97%、PO34--P81.02%;河道水体全盐量(TDS)浓度在4300～5200mg/L范围内波动,TDS浓度有所升高,增加量不大,只有850mg/L左右,表明洗盐基本结束。由此说明生态修复工程对泰达再生高盐水景观河道水环境质量改善效果明显。
Through the analysis of the practical water quality for a eco-restored project of landscape river with reused water from highly salty river water, the water purification effect and the salt content dynamic changing law in the river in saline-alkali land were studied. It was shown that main pollutant COD concentration in the water ranged from 54.15 to 94.15mg/L and had not been almost removed; nitrogen and phosphorus removal was very obvious; their maximum removal rates were respectively： TN 69.35%, NH3-N 50,75%, NO3-N 71,89%, TP 56.97%, PO4^3--P 81.02%; TDS in water fluctuated within 4300-5200mg/L; TDS increment was only about 850mg/L, indicating that salt washing finished basically. Thus the eco-restored project has obviously improving effect on the environmental quality of the reused highly salty water landscape river.
