塘西河生态补水和再生水厂尾水补给工程对水环境的影响
|
摘要
为探究塘西河生态补水工程和再生水厂尾水补给工程对水环境的影响,利用2012—2016年塘西河常规水质调查数据,综合分析了塘西河主要污染物浓度的时空变化特征,并对其影响因素进行分析。结果表明:1)TP和COD_(Mn)已经得到控制,而TN和NH_3-N在塘西河下游区域超标严重,是影响塘西河水质的主要污染物。从季节变化来看,采样点Z1和Z2的TN、NH_3-N和NO_3~--N含量基本上是在夏季较低而冬季较高;2)塘西河水质的季节波动受降雨和微生物影响显著,其主要污染物来源于降水和上游南艳湖泄水,南艳湖两岸为农田,所以调整流域土地利用结构,减少农业施肥与污水排放,是保护塘西河作为景观河道的关键。
To explore the effect of supplement project of ecological water and tailor water from reclaimed water plant on water environment of the Tangxi River,water quality characteristics in the Tangxi River was comprehensively analyzed using its water quality data during 2012—2016,respectively. The results indicated that: 1) TP and CODMnwere controlled,but TN and NH_3-N in the lower reaches of the Tangxi River exceeded seriously discharge standard,that was the main pollutants affecting water quality of the Tangxi River. From the perspective of seasons,TN,NH_3-N and NO_3~--N contents at Z1 and Z2 were usually lower in summer and higher in winter. 2) The seasonal fluctuation of water quality in the Tangxi River was affected by rainfall and microbes. The main pollutants were from the precipitation and the floods in the upper reaches of the Nanyan Lake.Both sides of the Nanyan Lake were farmland,so the land used structure was adjusted to reduce the agricultural fertilization and sewage discharge,which was the key measure to protect the Tangxi River as the landscape river.
