一种煤化工园区合成氨废水处理回用的工艺探讨

Exploration for a Reuse Technology Aiming at the Waste-water in Ammonia Preparation Based on the Large Coal Chemistry Industry Park

以煤化工园区为背景,以废水处理回用为目标,论述了一种合成氨废水的处理工艺。处理工艺主要包括气浮池、A/O池、臭氧氧化池、曝气生物滤池、无阀滤池等工艺处理单元。该工艺可以极大地降低合成氨废水中的污染物,且出水可以达到回用标准。

Based on the waste-water in production of ammonia in the large coal chemistry industry park, we explored a kind of technology to achieve the purpose of the industrial water reuse. The organic pollutants can be removed by the air flotation、A/O、ozone oxidation、BAF、no valve filtercombined technology, meantime, the water quality of the product water can meet the standard and requirements for the water reuse.
