Abstract: Cooperating with oxidation(H2O2),tourmaline can efficiently make the argazol blue BF-BR dyeing wastewater decolored.The decoloration rate of argazol blue BF-BR increases,with tourmaline dosage,oxidation dosage,temperature and contact time increasing.At pH=2 and 12,decoloration rate reaches maximum.Through orthogonal experiments,the optimum condition can be concluded that oxidation dosage is 1.5 mL,contact time is 9 min,tourmaline dosage is 1 g,temperature is 363 K and solution pH is 2.Under the optimum condition,the decoloration ratio can come up to 100%.Kinetic research indicates that the decoloration reaction of argazol blue BF-BR accords to one order kinetic reaction,and the kinetic equation can be described as follows:-lnCR=0.36733t-lnC0(R=0.9827),with reaction rate constant k=0.36733 min-1 and half life t1/2=1.887 min.Mechanism analysis shows that mineral-catalyzed Fenton-like reaction results in the decoloration of argazol blue BF-BR dyeing wastewater.

Abstract: The effect of bioflocculant MBF21 and cationic PAM with intermittent addition on anaerobic sludge bioflocculation in the UASB reactor was studied, compared with the reactor without any flocculants addition. Moreover, the connection between relative bioflocculant parameter BF/BF0 and the size of anaerobic granule was explored. The experimental results showed that the BF/BF0 value of sludge in the bioflocculant-added reactor, cationic PAM-added reactor and control reactor increased to 42.65, 40.45 and 21.89, respectively. The BF/BF0 values of sludge in the bioflocculant-added reactor and the cationic PAM-added reactor increased by 94.8 % and 84.8 % compared with the control reactor. The diameter of granules in each reactor increased to 1.04, 1.13 and 0.63 mm, respectively ; The diameter of granules in the bioflocculant-added reactor and the cationic PAM-added reactor increased by 65.1% and 79.4% compared with control reactor.

Abstract: 采用厌氧生物滤池(BF)与好氧膜生物反应器(MBR)组合工艺,以实际垃圾渗滤液为处理对象,在连续进水条件下,考察该工艺在处理垃圾渗滤液时,进水稀释倍率、厌氧/好氧(A/O)回流比和C/N比值对其硝化与反硝化特性的影响.结果表明,在处理稀释10倍的渗滤液时,氨氮和总氮的平均去除率分别稳定在90%和65%附近,回流比和C/N比值对好氧的硝化与厌氧反硝化反应的影响很小;在处理稀释5倍的渗滤液时,提高C/N比值能使厌氧反硝化能力增强,有效地消除亚硝氮的积累.渗滤液中有较高的浓度的氨氮与有机物负荷,容易对硝酸化菌产生抑制作用,使膜出水的亚硝氮积累明显,氨氮和总氮平均去除率分别稳定在69%~78%和46%~50%.

Abstract: 本文报道在制备光伏型InSb列阵探测器时采用BF工艺,使器件的串音率和光敏元边缘效应得到改善的结果。多元列阵器件中的串音现象严重地影响着红外探测系统的灵敏度和红外成象的质量。赵文琴等曾用H~ 轰击的方法取得了较好的隔离效果,但实际应用有困难。我们采用BF工艺获得了更为满意的结果。实验证实,BF工艺是解决多元列阵器件串音及单元光敏面

Abstract: 升流式厌氧污泥床(UASB)反应器被广泛应用于有机废水厌氧生物处理,在系统内培育出沉降性能良好、产甲烷活性高的颗粒污泥是其高效稳定运行的关键.用于启动UASB的接种污泥,一般采用厌氧活性污泥,而好氧活性污泥因其资源广泛易得在实际工程中也被广泛采用.然而,迄今为止,国内外研究者对厌氧颗粒污泥形成机制的研究均是以厌氧消化污泥作为接种污泥,而关于以好氧活性污泥为种泥的厌氧颗粒污泥形成机制少有报道.
