油田企业生活污水用于荒漠植被灌溉对生态环境的影响分析

Analysis on the Influence of Domestic Wastewater Used for Desert Vegetation Irrigation in Oilfield Enterprises on Ecological Environment

为了有效利用油田生产企业的生活污水,在某油田企业选取了21个能将生活污水用于荒漠植被灌溉的站点,结合各污水站基本情况及周边荒漠植被分布情况的现场调研,从中选取桑吉污水处理站作为研究样点,对油田生活污水用于荒漠植被灌溉对地下水、土壤和植被的影响进行研究。实验结果表明,达标生活污水通过滴灌和喷灌灌溉一年后,周边植被生长良好,地下水和土壤环境质量变化甚微,没有出现恶化现象。

In order to make effective use of domestic sewage in oil field production enterprises,21 stations that can use domestic sewage for desert vegetation irrigation were selected in an oil field enterprise.Combining the basic conditions of each sewage station and the distribution of surrounding desert vegetation,Sanji sewage treatment station was selected as the research sample point.The effects of oilfield domestic wastewater on groundwater,soil and vegetation for desert vegetation irrigation were studied.The experimental results showed that after one year of drip irrigation and spray irrigation,the surrounding vegetation grew well,the environmental quality of groundwater and soil changed little,and there was no deterioration phenomenon.
