摘要
介绍了塔器与生物接触氧化技术相结合处理石化污水的新技术。污水经处理后，ＮＨ＋４－Ｎ可以从５０～８０ｍｇ／Ｌ降到１０ｍｇ／Ｌ以下，ＣＯＤ从１００～２００ｍｇ／Ｌ降至８０ｍｇ／Ｌ以下。
A new technology combining a tower with bio-contact oxidation method was used to treat refinery wastewater The NH+4-N was decreased from 5080mg/L to less than 10mg/L, and CODcr was decreased from 100200mg/L to less than 80mg/L by means of the technology The shortest HRT(hydraulic residence time) was 3 hour
