A modified A2/O biological system is applied for the sewage treatment in a full-scale WWTP. Compared with conventional A2/O process, this modified A2/O process adds a pre anaerobic stage, and introduces inflow into pre-anaerobic, anaerobic and anoxic tank simultaneously. These measures bring about a further improvement of nitrogen and phosphorus in urban wastewater. The monitoring results for one year show that the influent concentrations of BOD, NH4-N, TN, TP are 21.9-263.0, 16.3-30.8, 9.7-668 and 1.0-11.3 mg L-l, respectively. After the treatment of modified A2/O process, the average effluent concentrations of BOD, NH4-N, TN, TP are 6.5, 0.6, 10.4, 0.6 mg L-l, and the average removal rates are 93.5%, 96.9%, 61.5% and 78.9%, respectively. The effluent quality meets the 1 B level discharging criteria in China. The operation results show that the modified A2/O process can achieve a high reduction of nitrogen and phosphorus in spite of the fluctuation of influent, and can be widely used in municipal wastewater treatment plants.
采用改进的A2/O生物系统对某污水处理厂进行污水处理。与传统的A2/O工艺相比,改进后的A2/O工艺增加了预厌氧阶段,同时将进水引入预厌氧、厌氧和缺氧池。这些措施使城市污水中氮磷含量得到了进一步的改善。1年监测结果表明,进水BOD、NH4-N、TN、TP浓度分别为21.9 ~ 263.0、16.3 ~ 30.8、9.7 ~ 668和1.0 ~ 11.3 mg L-l。经改性A2/O工艺处理后,出水BOD、NH4-N、TN、TP的平均浓度分别为6.5、0.6、10.4、0.6 mg L-l,平均去除率分别为93.5%、96.9%、61.5%和78.9%。出水水质达到中国B级排放标准。运行结果表明,改进后的A2/O工艺在不受进水波动影响的情况下仍能实现较高的氮磷还原,可广泛应用于城市污水处理厂。

Yogurt Drinking was a production of Lactic acid, was rich in various nutrients. In this paper, Yogurt Drinking was directly made from fermented milk, in which Lactobacillus casei and Lactobacillus helveticus were combined to encourage to the formation of flavor compounds. In this research, glucose in fermented milk was to speed up the browning. The optimum conditions of fermented milk are as follows: the ratio of L.c to L.h was 2:1, fermentation temperature was 30°C and inoculum sizeis was 3%(w/w). The optimum conditions of yogurt drinking were as follows: fermented milk 32%(w/w), sugar 6.4%(w/w), acidity of fermented milk was 200°T. The main components of the final production were determined as total solids 12.5%, protein 1.29%, the concentration of viable counts was 2.8×108 cfu/mL. Due to the lowest sedimentation rate, pectin was the the best stabilizer, moreover, the production made from pectin, was of uniform and exquisite texture and diverged special aroma. Suitable dosage was 0.26%(w/w). Acidity was an important factor of flavor in milk beverage. In our research, acidity from starter culture was distinct from traditional method of adding sour agent in the later period. This made up the defects of covering up the pure flavor by additives.
酸奶是由乳酸产生的,含有丰富的各种营养成分。本文以发酵乳为原料,将干酪乳杆菌和helveticus乳杆菌结合,促进风味化合物的形成,直接制成酸奶饮料。在本研究中,发酵乳中的葡萄糖具有加速褐变的作用。发酵乳的最佳条件为:l / l / h比为2:1,发酵温度为30℃,接种量为3%(w/w)。酸奶的最佳饮用条件为:发酵乳32%(w/w),含糖量6.4%(w/w),发酵乳酸度200°T。最终产品的主要成分为总固体12.5%,蛋白质1.29%,活菌计数浓度为2.8×108 cfu/mL。果胶的沉淀速率最低,是最佳的稳定剂,且果胶制品质地均匀细腻,散发出独特的香气。适宜用量为0.26%(w/w)。酸度是影响乳饮料风味的重要因素。在我们的研究中,发酵剂的酸度与后期传统的加酸方法不同。这弥补了添加剂掩盖风味纯正的缺陷。

In order to research the migration of contaminations from coal waste rock, based on local landform, flow direction of groundwater and wind direction around the coal waste rock dump of Yanma mine, samples of soil, groundwater and plant were collected and measured. The results showed that the contents of heavy metal, Bap and SO42- were high in coal waste rock, Zn and Cd had exceeded the grade III of Environmental quality standard for soils (GB15618-1995) in some samples. These components were also detected in soil and groundwater. The content of heavy metal and Bap was leaf>;stem>;seed for maize, and Bap was unattainment (7.395ng/g) in leaf. Background value of Mn was higher (422.09~599.03ppm). Mn was leached out from soil in leaching experiment, which made the Mn content of "coal waste rock + soil" leachate was higher. The above study showed that the migration of contaminants from coal waste rock to the environment was a long-term process.
为了研究矸石污染物的迁移,根据燕马矿矸石排土场周围的地形、地下水流向和风向,采集并测量了土壤、地下水和植物样品。结果表明:煤矸石中重金属、Bap和SO42-含量较高,部分样品Zn和Cd超过了《土壤环境质量标准》(GB15618-1995) III级。在土壤和地下水中也检测到这些成分。玉米重金属和Bap含量为叶片>茎>种子,叶片Bap含量为7.395ng/g;Mn的背景值较高(422.09~599.03ppm)。浸出试验中Mn从土壤中浸出,使得“煤矸石+土壤”渗滤液中Mn含量较高。上述研究表明,煤矸石污染物向环境的迁移是一个长期的过程。

Shells of Tahong {Perna viridis), Kuhol ((Helix pomatia), and Talaba (Crassostrea gigas) are considered wastes and are normally dumped in open garbage areas or back to the aquatic system. Many studies showed that family of oysters, mussels, and snails are used as bio-indicators or used in accumulation monitoring studies of metals like Cd, Pb, Cu and Hg since their soft tissues absorb it. Their shells, as they may contain chitin or chitosan may also have the ability to absorb heavy metals.As the waste shells are being reused/recycled, waste materials in the environment are decreased. Vectors of diseases that swarm waste areas will be diminished and thus safeguard public health.In general, this study aimed to assess the ability of shells of Perna viridis (tahong), Crassostrea gigas (talaba) and Helix pomatia (kuhol) to de-lead simulated lead-contaminated waste water. Specifically, this study aimed to compare the ability of shells of Perna viridis (tahong), Crassostrea gigas (talaba) and Helix pomatia (kuhol) to de-lead simulated lead-contaminated waste water. It also aimed to assess if concentrations of lead in waste water affect the absorption of lead by the shell samples and if variances in types of shells affect absorption of lead in waste water. Tahong, Talaba and Kuhol absorbed lead in simulated waste water. However, the inherent amount of lead in the different shells affected its ability to absorb it. Talaba and kuhol, due to its inherently high lead concentrations failed to absorb lead from simulated waste water as the amount of the heavy metal increased. Statistical analysis showed that the concentrations of the simulated waste water affected the absorbance of lead by chitin and chitosan from different shells. Also, chitin and chitosan extracted from different kinds of shells affected lead absorption in varied concentrations of simulated waste water. Tahong shells showed the most efficient absorption of lead from simulated waste water preparations. Using the different shells in the differently concentrated SWW, the percentage of lead removed ranged from -15.899% to 63.539%. Flameless Atomic Absorption Spectrophotometer was used to quantitate the lead levels in simulated waste water, and chitin and chitosan extracted from the three waste shells used in this study. As there is promise to clean the waste waters from lead pollutants using Tahong, Talaba and Kuhol, it is recommended that other shell wastes be studied for similar objectives as this study. Likewise, pH of waste water, time of contact, temperature during treatment and agitation must be looked into to optimize the de-leading ability of these shells. Further absorption of other heavy metals is suggested to be analyzed as well.
Tahong {Perna viridis)、Kuhol ((Helix pomatia))和Talaba(长牡蛎)的壳被认为是废物,通常被倾倒在露天垃圾区或返回水生系统。许多研究表明,牡蛎、贻贝和蜗牛科因其软组织吸收Cd、Pb、Cu和Hg等金属而被用作生物指标或用于镉、铅、铜和汞等金属的积累监测研究。它们的外壳,因为它们可能含有几丁质或壳聚糖,也可能有吸收重金属的能力。由于废物壳被重复使用/循环再造,环境中的废物减少了。将减少聚集在废物区的疾病媒介,从而保障公众健康。总的来说,本研究旨在评估Perna viridis (tahong), Crassostrea gigas (talaba)和Helix pomatia (kuhol)的壳对模拟铅污染废水的去铅能力。具体而言,本研究旨在比较Perna viridis (tahong), Crassostrea gigas (talaba)和Helix pomatia (kuhol)的壳对模拟铅污染废水的去铅能力。它还旨在评估废水中的铅浓度是否会影响贝壳样品对铅的吸收,以及贝壳类型的差异是否会影响废水中铅的吸收。塔洪、塔拉巴和库霍尔吸收了模拟废水中的铅。然而,不同外壳中固有的铅含量影响了其吸收铅的能力。随着重金属含量的增加,塔拉巴和库霍尔由于其固有的高铅浓度而未能从模拟废水中吸收铅。统计分析表明,模拟废水的浓度影响不同壳质和壳聚糖对铅的吸光度。此外,从不同种类的壳中提取的几丁质和壳聚糖对不同浓度模拟废水中铅的吸收也有影响。塔红壳对模拟废水中铅的吸收效果最好。在不同浓度的SWW中使用不同的壳,铅的去除率在-15.899% ~ 63.539%之间。采用无焰原子吸收分光光度计对模拟废水中的铅含量进行了定量分析,并对从三种废壳中提取的甲壳素和壳聚糖进行了定量分析。由于使用Tahong, Talaba和Kuhol有希望清除废水中的铅污染物,因此建议研究其他贝壳废物以达到类似的目的。同样,废水的pH值、接触时间、处理过程中的温度和搅拌也必须加以考虑,以优化这些壳的脱铅能力。建议进一步分析其他重金属的吸收情况。

Hydroxyquinol 1, 2-Dioxygenase is a key enzyme for p-nitrophenol (PNP) catabolism in bacterium. In this paper, we cloned a pnpC gene encoding hydroxyquinol-1, 2-dioxygenase from Pseudomonas sp. strain HS-D38 that could degrade PNP efficiently. The open reading frame of the pnpC contained 873 nucleotides and the deduced molecular mass of gene product (PnpC) was 33 kDa The recombinant enzyme was highly expressed in E. coli BL21(DE3) as a histidine-tag fusion protein and purified to homogeneity by Ni-NAT affinity chromatography. The specific activity of the purified protein reached at 9.3 U/mg. The maximum activity of the recombinant enzyme towards catechol was exhibited at 45 V and pH5.0.

羟基喹啉1,2 -双加氧酶是细菌对硝基酚(PNP)分解代谢的关键酶。本文从假单胞菌HS-D38菌株中克隆了一个能有效降解PNP的羟基喹啉- 1,2 -双加氧酶基因。重组酶在大肠杆菌BL21(DE3)中以组氨酸标签融合蛋白的形式高表达,并通过Ni-NAT亲和层析纯化。纯化后的蛋白比活性达到9.3 U/mg。重组酶在45 V和pH5.0条件下对儿茶酚的活性最大。0.2 mM的Fe3+、Fe2+、Cu2+、Zn2+、Mn2+和Co2+均能刺激酶活性。上述结果为PnpC在PNP污染物生物降解中的应用提供了有益的信息。

There has no matching water quality model reported in literature so far, although the hydraulic model of plain river network has been established by utilizing the cell-dividing method in the past decades. The feasibility and efficiency of the cell-dividing method used to solve water quality variables is demonstrated in this paper. A novel combined-cell water quality model based on cell-dividing method is proposed and applied to stimulating the water quality of Nantong river network of China, with results, showing the efficiency and accuracy of the proposed method.
平原河网的水力模型虽在近几十年利用细胞划分法建立,但目前文献中尚未见与之匹配的水质模型。本文论证了用细胞分裂法求解水质变量的可行性和有效性。提出了一种新的基于细胞分裂法的组合细胞水质模型,并将其应用于南通河网水质模拟,结果表明了该方法的有效性和准确性。
