摘要
采用一套兼氧型FMBR装置对江西某印染厂直接排放的实际废水进行处理,实验持续一个半月,反应器内污泥浓度达到并相对稳定在10000 mg/L左右.水力停留时间为30 h、出水量为2.2 m3/h时,装置对COD、NH3-N和色度表现出很好的去除效果,出水COD、NH3-N和色度平均分别为62.0 mg/L、7.1 mg/L和37倍,平均去除率分别为89.8%、82.4%和88.7%,设备出水水质稳定达国家《纺织染整工业水污染物排放标准》(GB4287-2012)2015年修改后的要求.反应器有效容积达65 m3,实验数据对中小型工程建设有一定的参考价值.
Using a type of facultative anaerobic membrane bioreactor (FMBR) to deal with the wastewater in dyeing factory of Jiangxi province. The experiment lasts for one month and a half and the sludge concentration in reactor achieved and relatively stable at around 10000 mg/L, when the hydraulic retention time is 30 h and the flow rate of the equipment is 2.2 m^3/h, the reaction showed very good effect for the removal of COD and NH3-N and chroma, the average COD, NH3-N and color of the equipment were 62.0 rag/L, 7.1mg/L, and 37 times, respectively. And the average removal rate was 89.8 %, 82.4 % and 88.7 % respectively. The outlet water quality of the equipment can reach national "textile dyeing and finishing industrial water pollutant discharge standard" (GB4287-2012) in 2015, the revised requirements. The effective volume of the reactor is about 65 m^3 and the experimental data would have a certain reference value for small and medium-sized construction of projects.
