摘  要:
根据国家环保部门公布的数据,对渭河流域陕西段2005~2009年5年的水体分析,结果表明,水体的COD含量优于国家I类地表水标准,但是,氨氮指标和溶解氧的指标超标,最根本的原因是水体氨氮含量过大,进而耗费水中的氧,使溶解氧的指标下降。提出了对已建的污水处理工厂,应用生物脱氮技术和物理化学处理技术对氨氮进行深度处理,并将氨氮作为考核出水的主要指标,同时,应该对生活污水进行集中处理。

摘  要:
The water body of Shannxi reach of Weihe River was analyzed according data from Ministry of Environment Protection during 2005 to 2009;the results showed that the COD content is better than I class index value,but the NH3-N and DO contents are over range Vclass index value.The reason is that the concentration of NH3-N is high in the water body.Some suggestions were put forward that the biology-denitrogenation technology and physical-chemical process should be used in NH3-N disposal and domestic sewage should be centralized processing.
