针对染料废水的色度大,有机物含量高,可生化性差的特点,采用了微电解-厌氧-好氧组合工艺处理染料废水。结果表明:该工艺对染料废水有很好的处理效果,最终出水COD为45~91mg/L,出水清澈无色,达到工业水污染物排放一级标准(GB8978-1996),处理成本仅为1.57元/m^3废水。
Dyastuffwastewater with high chroma and COD is difficult to be treated by microbe. In this paper, a micro-electrolysis-anaerobic-aerobic combined technique was developed to treat the dyastuffwastewater. The experimental results was obtained and showed that: the effluent COD was below 100mg/L, and the effluent water was clear and colorless, meeting the requirements of the national first grade standard of industrial wastewater discharging (GB8978-1996), and the cost of whole treatment was only RMB 157 yuan/m^3 wastewater.
