奥运森林公园再生水绿地灌溉研究

Reclaimed water irrigation in the Olympic Forest Park.

该文介绍了奥运森林公园再生水的利用规划,指出奥运森林公园的水系特点及再生水的重要性.通过实地调查和小区试验来评估不同水质灌溉对城市草坪及植被的影响.结果表明,用二级水及不同工艺的三级出水进行草坪绿地和植被灌溉后产生了不同影响,二级水对植物细胞膜的稳定性有一定的破坏性.三级水尤其是反渗透出水不仅带来草坪需要的氮和磷,同时可以提供充足的微量元素,大大降低出水的重金属含量,对植物毒害作用小.同时指出,在结合再生水工艺及技术基础上,应该细化城市绿地灌溉的相关标准.

Wastewater reclamation and reuse in the Olympic Forest Park are introduced. It is an effective way to solve the water shortage problem in Beijing. The effects of reclaimed water irrigation on grass and plants were evaluated by conducting plot experiment and field survey. Results showed that the secondary effluent can destroy the stability of plant cells. However,the tertiary water can not only provide adequate N,P and some microelements, but also reduce the heavy metals, which have little harm to the grass....
