摘　　要：海带加工废水属高浓度有机废水(HCOWW)。将HCOWW处理回用,实施清洁生产,对于进一步发展沿海经济,意义重大。采用自行设计制作浸没式膜生物反应器(iMBR),进行海带加工废水的处理实验,重点考察iMBR处理废水的效果及其影响因数。结果表明,iMBR对CODC r,NH4-N,TP和甲醛(HCHO)的平均去除率分别达到95.2%、93.8%、58.8%、99.2%。优化反应器中水力停留时间、容积负荷、HCHO浓度,好氧iMBR系统运行稳定。这对于处理HCOWW的iMBR工程的建设与运行,都具有重要指导意义。The kelp processed wastewater is a high concentration organic wastewater（HCOWW）.It is of great importance to further development of coastal economy if HCOWW from the kelp industry is treated and reused.A setup pilot scale submerge membrane bioreactor（iMBR） made by ourselves was used in the test.The impact factors and the treatment effect of wastewater in iMBR system were emphasized.The results showed that the data of removal efficiency for CODCr,NH4-N,TP and HCHO were 95.2%,93.8%,58.8%,99.2%,respectively.The aerobic iMBR run stably as an operation conditions of HRT,volumetric loading rate,HCOHO concentration in the reactor were optimized.The work is an importance guide significance to build and operate of iMBR engineering of HCOWW.
