【摘要】 某制丝企业综合废水水质参数:ρ(CODcr)=692～915mg/L,ρ(BOD5)=207～275mg/L,ρ(NH3-N)=26～42mg/L,ρ(SS)=372～428mg/L。采用水解酸化-生物接触氧化法处理,运行结果表明,处理后出水:ρ(CODcr)=39mg/L,ρ(BOD5)=8.4mg/L,ρ(NH3-N)=0.9mg/L,ρ(SS)=41mg/L,色度25倍,符合排放要求。更多还原

【Abstract】 The quality parameters of the combined wastewater from the silk production of someone mill. Were: ρ （CODc_r）=692～915mg/L, ρ （BOD₅）=207～275mg/L, ρ （NH₃-N）=26～ 42mg/L, ρ （SS）=372～428mg/L. The wastewater was treated by a process of hydrolytic acidification-biological contact oxidation. The results of the operation showed that the quality parameters of the effluent water after the treatment were as follows: ρ （CODc_r）=39mg/L, p （BOD₅）=8.4mg/L, ρ （NH₃-N）=0.9mg/L, ρ （SS）=41mg/L, and chroma=25 times, indicating that the quality of the treated wastewater met the discharge standard.更多还原
