摘要
高浓度有机废水的厌氧消化出水水质较差，用氧化沟工艺补充处理收效良好。当厌氧出水的ＣＯＤ浓度低于７００ｍｇ／Ｌ时，补充处理后达到国家排放标准。但当ＣＯＤ浓度高于７００ｍｇ／Ｌ时，补充处理难以达标，究其原因，可能与曝气刷的充氧能力较弱有关。
The quality of anaerobic effluent of organic wastewater with high COD concentrationwas poor and the polishing treatment with an oxidation ditch reactor showed a good result.It couldreach the state discharge standard after the effluent with COD concentration less than 700 mg/Lwas treated.When the effluent with COD concentration rnore than 700 mg/L was treated,howev-er,it was difficult to reach the standard because of the weak aeration capacity of Kesner brush;
