内电解-接触氧化法处理松香及樟脑生产废水

Treatment of colophony and camphor wastewater by inner electrolysis-biological contact oxidation

研究采用内电解-生物接触氧化法处理松香及樟脑混合废水。试验结果表明,在内电解反应时间为8h,二段生物接触氧化系统水力停留时间为16h的条件下,系统出水CODCr<150mg L,达到污水综合排放标准的二级标准。内电解处理可提高此类废水的可生化性。

The treatment of colophony and camphor wastewater by inner electrolysis- biological contact oxidation has been studied. The results show that the final effluent CODCr can be controlled under 150 mg/L when the inner electrolysis reacting time is 8 hours and the biological contact oxidation HRT is 16 hours. The inner electrolysis can increase the biodegradability of this kind of wastewater.
