鸟嘌呤生产废水的处理

Treatment of Wastewater from Guanine Production

鸟嘌呤废水具有CODcr高达40000mg/L、氨氮含量达2400mg/L,呈强酸性。采用先对工艺废水进行预处理 ,再用低浓度废水调整水质 ,然后经水解、接触氧化最终出水的CODcr为130～150mg/L,NH3-N≤25mg/L。

The CODcr in the wastewater from guanine production is as high as 4 000 mg/L and the NH3_N content in the wastewater is as high as 2 400 mg/L. The wastewater is strongly acidic.By first pretreating the process wastewater and then adjusting the quality of the water with low_concentration wastewater,which were followed by hydrolysis and contact oxidation,the CODcr in the final outlet water was 130～150 mg/L,with NH3_N≤25 mg/L.
