微碳SBR法处理洗舱化学废水试验研究

EXPERIMENTAL STUDIES ON THE TREATMENT OF CABINWASHING CHEMICAL WASTEWATER BY MICRO-PAC SBR PROCESS

以微碳非限量曝气ＳＢＲ法处理港口有机散化洗舱废水，稳定有效。进水ＣＯＤ浓度３０００ｍｇ／Ｌ，出水＜２００ｍｇ／Ｌ，ＣＯＤ去除率９０％以上。工艺运行周期１２ｈ（其中进水３ｈ，曝气８ｈ，沉淀２ｈ，排水及闲置各１ｈ）。还对有机物降解去除规律进行了分析探讨。

The studies show that cabin-washing chemical wastewater with a relatively stable in fluent COD of 3000mg/L or so is treated to less than 200mg/L COD equivalent to a COD removal of 90% over,by SBR process with micro-PAC and unconfined aeration in a operation cycle period of 12h. The law of organic degradation is also discussedin the paper.
