Abstract

Abstract:

The combined technology of multi-stage AO process and chemical dephosphorization was applied to treat the black-odorous river in Hebei Province, which significantly improved river water quality. The results showed that the COD_Cr, ammonia nitrogen and TP of the effluent met Class V of Surface Water Quality Index(GB 3838-2002). The successful treatment of the river can provide engineering demonstration and technical reference for the regulation of black and odorous water.

Key words: black and odorous water, multi-stage AO process, combined technology, river treatment

摘要：

针对河北省某河道的污染情况，确定采用运用多级AO与化学除磷的组合工艺进行治理，使河水水质明显改善。工程实践表明：出水中污染物COD_Cr、氨氮和TP均达到《地表水环境质量标准》（GB 3838—2002）Ⅴ类地表水水体标准。该河道的成功治理，可为黑臭水体治理提供技术借鉴和工程示范。
