中文摘要 |
研制了一种具有抽滤和曝气双重功能的陶瓷膜生物反应器并用于处理废水.比较了废水经陶瓷膜抽滤后的出水浊度和自然沉降后的浊度,经过陶瓷膜过滤后的出水浊度达到自然沉降4~24h的效果.在处理废水的过程中,进行曝气/抽滤的切换,可有效地解决膜的堵塞问题.分别进行了间歇和连续的方法处理废水的试验,其COD负荷分别达到1.1kg/(m3·d)和1.5kg/(m3·d). |
英文摘要 |
A new bioreactor including ceramic dual function membrane, filtration and aeration, was developed and used for wastewater treatment. The turbidity of effluent by the ceramic membrane was comparable to that of 4~24 hours by sedimentation. Aeration and filtration could be switched constantly to the ceramic membrane in the bioreactor and the clogging of ceramic membrane could be well prevented. The wastewater was treated in batch and continues operation modes respectively and the experimental results showed that the COD loading was 1.1kg / (m3·d) and 1.5 kg/(m3·d) respectively |
