双膜法深度回用石化炼油废水中试
Advanced treatment and reuse of petrochemical refining wastewater with membrane technology
摘要
Abstract
This paper attempts to address the environmental hazards caused by the wastewater with complexed composition in petrochemical industry,and proposes a new wastewater treating method named"ultrafiltration + reverse osmosis"double membrane process.The study includes oxidizing raw water,which is the petrochemical refinery wastewater,with sodium hypochlorite;coupling with ultrafiltration and reverse osmosis technology;and contracting the"ultrafiltration + reverse osmosis"double membrane process to treat deeply and test reuse.The results indicate that the turbidity and SDI15 of ultrafiltration water are stable below 0.1 NTU and 3,respectively,with stable operation and good cleaning perform-ance,which is a guarantee for the stable operation of reverse osmosis.The removal ratio of COD,hard-ness,TDS and ammonia nitrogen of reverse osmosis produced water are above 98.2%,99.3%,99.3%and 73.3%,respectively,and the quality of produced water is superior to the water quality standard of circulating cooling refilled water.关键词
