丙烯腈装置废气污水处理技术与设备改进

Improvement of exhaust & sewage treatment technology and equipment for acrylonitrile plant

采用日本巴布柯克-日立公司工艺技术,对废水焚烧炉进行改造;优化废水处理方式,对低质量浓度污水进行处理后进行回用;与环境工程公司合作,共同研究开发废水处理工艺,对污水处理场进行改扩建。技术与装置改进后,废气中非甲烷烃痕量排放,废水外排量和新鲜用水量明显减少,污水处理场出水达标排放,产生良好的经济效益和环境效益。

The waste water incinerator is modified with Japanese Papua Kirk-Hitachi technology. The low concentration wastewater is treated for reuse by optimizing the wastewater treatment methods. New wastewater treatment process is studied with environmental engineering company to reconstruct the sewage farm. After the improvement of technology and equipment, the trace emission of NMHC is achieved. Wastewater emission load and fresh water use load reduce significantly. Sewage treatment effluent is up-to-standard release, which produces good economic benefits and environmental benefits.
