SBR法处理化学药物制剂废水

Treatment of chemicals medicine wastewater by SBR process

采用 ＳＨＲ法处理化学药物制剂废水． 调节 ｐＨ至７．５，进水 ＣＯＤｃｒ ２２４～１５３０ ｍｍ／Ｌ，曝气１０ ｈ， ＣＯＤｃｒ容积负荷达２．５８ｋｇ／ｍ~３·ｄ，ＣＯＤｃｒ的去除率高达９４．２％，处理后出水ＣＯＤｃｒ＜１００ｍｇ／Ｌ，达到综合排放标准（ＧＢ８９７－９６）一级标准。ＣＯＤｃｒ容积负荷至３．８４ ｋｇ／ｍ~３·ｄ， ＣＯＤｃｒ去除率仍＞８５．９％。

The condition of chemicals medicine wastewater treatment by SBR were showed as follows: the CODer of inflow was in the range of 224~1530 mg/L f CODcr volume load of the reactor was 2.58 kg CODer/m^3·d and the pH value of wastewater was adjusted to 7.5. When the wastewater was aerated for 10 hours, the CODcr removal efficiency could reach 94. 2 % and the CODer of effluent was less than 100 mg/L, which met the requirement of the first degree standard of wastewater synthetic discharge standard. When CODcr volume load rised to 3. 84 kg CODcr/m^3·d, the CODcr removal efficiency could still be more than 85. 9 %.
