摘要
本文介绍了炼油厂重油加工污水的生化处理工艺。阐述了污水处理中CAST工艺的结构,其特点是高效、稳定、工艺流程简单。结论表明,CAST生化处理系统在去除污水中有机污染物的同时具有较好的硝化与反硝化功能。CAST工艺的污水处理厂具有较高的自动化水平,可大大降低污水的运行成本,对炼油厂的污水处理完全能够达到国家一级排放标准。
The biochemical treatment technology of refinery sewage was introduced. Characteristics and structure of CAST technology in sewage treatment were discussed in detail. The main characteristics of which is high-efficiency, stability and Simple process. The operation results show that the CAST biochemical treatment system has better nitrification and denitrification. Sewage treatment plant using CAST Process has so high automation level that it can greatly reduce the cost of wastewater treatment plant of operation, refinery sewage treated by the CAST biochemical treatment system can fully meet the national emission standard.
