义和站污水水质评价及处理技术研究

Assessment of Sewage Quality and Research of Sewage Treatment Technique at Yihe Station

胜利油田义和站污水处理不达标,文章在分析评价污水水质的特点、影响水质净化和水质稳定主要因素的基础上,研究了各种水处理剂包括净化剂、杀菌剂、缓蚀剂、脱硫剂、水质改性剂等对水质的影响,最后确定采用二氧化氯预氧化、水质改性和缓蚀技术,使处理后的污水达标回注。

The sewage treatment quality at Yihe Station of Shengli Oilfield was below the standard.Based on analyzing the sewage quality and factors affecting purification and stability,the effects of various water treatments such as depurant,bactericide,corrosion inhibitor,desulfurizer and water quality modifier on water quality are investigated,finally some techniques including pre-oxygenation with chlorine dioxide,water quality modification and corrosion inhibition are adopted to enable the sewage to meet the rejection standard.
