氧化沟工艺处理厌氧消化出水的研究

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。

Study on anaerobic effluent treatment with an oxidation ditch reactor.

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;
