| 摘 要： | 考察了自主研发的高效厌氧和微滤(MF)组合工艺对垃圾焚烧发电厂产生的渗滤液中COD的去除效果,以及微滤系统对SS的拦截效果。结果表明,高效厌氧和MF系统可使COD浓度由40 000 mg/L以上降至1 900 mg/L以下,对COD的平均去除率可达96. 5%,微滤系统可拦截97. 6%的SS。当微滤膜产水量降低时,通过对其进行正确合理的清洗,可最大限度恢复膜通量。另外,针对试验过程中出现的泡沫和排泥问题,提出了相应建议。

| Abstract: | The removal efficiency of COD in leachate from a waste incineration power plant by selfdeveloped high efficiency anaerobic and microfiltration ( MF) system was investigated, and the rejection effect of MF system on suspended solids ( SS) was explored. The results showed that COD concentration could be reduced from more than 40 000 mg/L to lower than 1 900 mg/L by the high efficiency anaerobic and MF systems. The average removal rate of COD was 96. 5%, and 97. 6% of SS could be intercepted by the MF system. When the membrane flux was reduced , it could be restored to the maximum by proper and reasonable cleaning. Furthermore, relevant suggestions were put forward according to foam and sludge discharge problems occurring in the process of experiment. |
