The heliotropin production wastewater has high organic matter concentration,unstable water quality,and complicated components and is hard to biodegrade.The physicochemical technique(ferric-carbon micro-electrolysis combined Fenton oxidation process) and biochemical technique were applied to treating the perfume wastewater.The experimental results indicate that after the treatment,the concentration of COD of outlet water is 240 mg/L,and that of NH3-N is 5 mg/L.The removal rates of two techniques are 98% and ...
