Abstract:

Gibberellin was produced by biological fermentation method in a biochemical company,in Jiangxi,China, and a great deal of SO₄^2- organic wastewater produced in the production process. The combined process,IC+double-pole UASB+AO has been used for treating this organic wastewater. The operation results show that under stably run-ning conditions of the system,when the influent faffinate COD,NH₃-N,and SO₄^2- are 25 100-27 350,165-199.7 and 12 020-22 225 mg/L,respectively,the treated effluent COD,NH₃-N,and SO₄^2- are 78.2-87,2.2-3.5 and 75.5-85.2 mg/L,respectively. The water quality of effluent is better than the first class criteria specified in Integrated Wastewater Discharge Standard(GB 8978-1996).

摘要：

江西某生化公司以生物发酵法生产赤霉素，在生产过程中产生大量高SO₄^2-有机废水，该公司采用IC+两级UASB+AO的组合工艺处理该有机废水。运行实践表明，在系统稳定运行条件下，当工艺进水萃余液COD、NH₃-N、SO₄^2-分别为25 100~27 350、165~199.7、12 020~22 225 mg/L时，处理出水COD、NH₃-N、SO₄^2-分别为78.2~87、2.2~3.5、75.5~85.2 mg/L，出水水质优于《污水综合排放标准》（GB 8978-1996）的一级标准。
