The start-up of treating alkali-deweighting and dyeing-printing wastewater by anaerobic baffled reactor (ABR) was investigated. Through seeding with the anaerobic granular sludge, the start-up with low organic loading was started by using artificial alkali-deweighing and dyeing wastewater as influent with the condition of temperature 32 degrees C-35 degrees C and pH 7.8-8.3. After continuously running 70 days, the start-up had been completed to reach the stabilization. The results showed that the pH of effluent kept stable around 7.3 and the average COD removal rate was up to 78% while the average volume loading rate was 1.93 kg x (mm3 x d)(-1). After the start-up, a separating function of each compartment was observed and meanwhile the anaerobic granular sludge with good properties was achieved. Relative to the start, the size of granular sludge particle was increased and the sludge sedimentation performance became better and the value of f (MLVSS/MLSS) was up to 0.65 at the end of the experiment. In addition, high activity of the microorganism was observed that the average value of dehydrogenase activity (DHA) with TF expression and the coenzyme F420 concentration were x (g x h)(-1) and 0.18 micromol x g(-1), respectively.
研究了厌氧折流板反应器(ABR)处理碱减量印染废水的启动过程。通过接种厌氧颗粒污泥,以人工碱减量印染废水为进水,在温度32℃ - 35℃、pH值7.8 - 8.3的条件下,采用低有机负荷启动。连续运行70天后,启动完成并达到稳定状态。结果表明,出水pH值稳定在7.3左右,平均COD去除率高达78%,平均容积负荷率为1.93 kg·(m³·d)⁻¹。启动后,观察到各隔室具有分离功能,同时获得了性能良好的厌氧颗粒污泥。相对于启动初期,颗粒污泥粒径增大,污泥沉降性能变好,实验结束时f(MLVSS/MLSS)值高达0.65。此外,观察到微生物活性较高,以TF表示的脱氢酶活性(DHA)平均值和辅酶F420浓度分别为x(g·h)⁻¹和0.18 μmol·g⁻¹。
