摘要
高浓度亚麻脱胶废水COD_(Cr)、色度都很高,不宜直接进行生物处理。试验采用酸析—微电解—Fenton氧化的预处理工艺,并对反应的影响因素进行了研究,试验结果表明,在pH=3,微电解90 min,H_2O_2投量1500 mg/L,Fenton氧化120 min的条件下,COD_(Cr)去除率可以达到71.4%,色度去除率超过90%。同时该方法提高了废水的可生化性,有利于后续的生化处理。
With very high CODcr concentration and high color, flax degumming wastewater is not suitable for biological treatment directly. According to wastewater quality, acidolysis-micro-electrolysis-Fenton oxidation processes were used to pretreat flax degumming wastewater and the influencing factors on this process are researched experimentally. The results showed that removal rates for CODcr and color reached 71.4% and 90% respectively under condition of influent pH value of 3, micro-electrolysis of 90 min, H202 dosage of 1 500 mg/L and Fenton oxidation of 120 min. It was proved that biodegradability of wastewater had been improved obviously by this process and the following biological treatment would be enhanced.
