摘要：
为了节省酸法浸铀过程中氧化剂用量,以多孔耐酸陶粒作载体固定耐冷嗜酸硫杆菌,在新疆某酸法地浸采铀矿山构建了高7.0 m、内径2.0 m、总容积17.8 m^3的新型高效生物反应器,进行快速氧化地浸采铀吸附尾液中Fe^2+扩大试验研究。研究结果表明,在现场温度为5~24℃、吸附尾液中Fe^2+浓度为200~300 mg/L、通气量为59.0 m^3/h时,生物反应器的最大流量可达28.2 m^3/h,Eh(氧化还原电位)大于570 mV,尾液中Fe^2+在低温环境下可被快速完全氧化。该试验结果为细菌代替氧化剂氧化吸附尾液中Fe^2+的拓展应用提供了借鉴意义。

摘要：
Radon diffusivity is a key parameter for estimating radon emanation from porous media. We have developed a Monte Carlo method for determining radon diffusion coefficients in porous media. In the proposed method, the probability model for pore diameter derived from fractal theory is used to describe the microscopic pore structure of porous media. The Monte Carlo technique is utilized to search for the pore size that satisfies the probability model for porous media. The convergence rate of the proposed is fast (∼3 min). Radon diffusion coefficients measured by the closed chamber method are used to validate the accuracy of the proposed method. © 2019 Elsevier Ltd

摘要：
为了掌握铀矿冶生产实践中常用设备材质经放射性污染后表面活度的变化规律,研究了不锈钢、有机玻璃、橡胶3种材质经不同浓度的硝酸铀酰溶液连续浸泡26 d后,样品表面活度、表面形貌及铀的存在形式等变化特征。结果表明:在26 d内,当铀溶液质量浓度为10.22 mg/L时,3种材质表面活度随浸泡时间增加变化不显著,当溶液铀质量浓度分别为563.58 mg/L、25.54 g/L时,各材质表面活度值均随浸泡时间增加逐渐增大。此外,3种材质表面活度从大到小依次是橡胶>不锈钢>有机玻璃。样品表面活度的增加主要是由于样品被腐蚀,导致铀在样品表面的附着沉积引起,并且表面的铀主要以UO_2(NO_3)_2·6H_2O及少量UO_3的形式存在。

摘要：
Cyanobacteria are freshwater microorganisms that can bloom and produce toxins that contaminate water. There is thus a need for methods to remove cyanobacteria, by flocculation for instance. Here, we prepared new flocculants by modifying waterwork sewage sludge. Flocculant (A) or (B) were prepared by treating 3 g of preprocessed sludge in hydrochloric acid and heating at 200 or 250 °C for 3.0 h. Flocculant (A) and (B) were used to remove Microcystis aeruginosa colonies by adding 0.75 mL of flocculant to 100 mL of algal culture and incubating for 8 h. Results show removal efficiencies of 72 and 91%, respectively. Total nitrogen was reduced by 30 and 12%. Total phosphorus was reduced by 75 and 76%. Chlorophyll fluorescence showed that cyanobacterial cells were removed without damaging the membrane integrity. Overall, findings show that modified waterworks sludge flocculants have good potential for the control of algal blooms, the removal of total nitrogen and total phosphorus and the restoration of aquatic ecosystems. © 2017, Springer International Publishing AG.

摘要：
Cyanobacteria blooms have received increasing attention due to their role in causing serious economic losses and endangering human health, leading to illnesses or even death. Thus, their removal by effective means is very important. A new botanical flocculating agent, tannin, was prepared from pomegranate peel. The influence factor of pomegranate peel tannin on Microcystis aeruginosa removal, including volume fraction of acetone aqueous solution, ratios of material to solvent, extraction temperature, extraction time and the addition of pomegranate peel tannin, was also investigated to determine the best preparation condition. Under the optimal conditions, the removal efficiency of pomegranate peel tannin flocculant on M. aeruginosa cells was 94.22%, and the removal efficiency of the same concentration chemical tannin on M. aeruginosa cells was 95.95%. According to these results, tannin could effectively flocculate and remove M. aeruginosa cells.

摘要：
In recent years, harmful cyanobacterial blooms frequently occurred all over the world, causing great damage to ecosystems, fishery resources, and recreational facilities. Therefore, the removal of harmful cyanobacterial blooms is a crucial step for the maintenance of safe water supplies and for the safety of aquatic products. Hydrogel beads based on sodium alginate and an aqueous extract from pomegranate peel were prepared, and used for removing Microcystin aeruginosa. The removal efficiencies of hydrogel beads to M. Aeruginosa and the factors affecting its removal from solutions (the ratio of material to solvent, the dosage of hydrogel beads, and the density of M. Aeruginosa cells) were investigated. The optimum ratio of material to solvent, the dosage of hydrogel beads and the density of M aeruginosa cells were 0.03 g/cm, 100 g/dm and less than 8.68 106 cells/cm, respectively. When the density of M. Aeruginosa cells was below 8.68 106cells/cm, the removal efficiency of cyanobac-teria was above 99.21% at the dose of 100 g/dm. The pomegranate peel and sodium alginate, as natural materials, were safe and innocuous, providing simple operation, low cost and high availability. Therefore, the hydrogel beads offer favorable characteristics in M. Aeruginosa removal. © 2018 Technical University of Wroclaw. All rights reserved.

摘要：
Based on previous research, muriatic modification parameters (including the volume of hydrochloric acid, modification temperature and reaction time) were optimized by L<inf>9</inf>(3<sup>3</sup>) orthogonal design using the removal efficiency of unicellular M. aeruginosa as an index. The results showed that the optimized modification conditions consisted of a hydrochloric acid volume of 4 mL, a modification temperature of 200 °C and a reaction time of 3 h. Under the above conditions, the removal rate for unicellular and colonial M. aeruginosa was 89.26 and 75.53%, respectively. In addition, the flocculation process caused no cell damage, and the cells remained intact after use of the modified water treatment residuals (WTRs) flocculant. TP and TN in water were reduced by 63.37 and 19.03%, respectively. Therefore, the modified WTR flocculant was a technically viable method to remove unicellular and colonial M. aeruginosa. ©2017, Islamic Azad University (IAU).

摘要：
A method was developed for cyanobacteria bloom (unicellular and colonial Microcystis aeruginosa) mitigation using calcium hydroxide and an illite composite algicide. The maximum cell removal efficiency was 84.72% when calcium hydroxide was used alone. When illite and calcium hydroxide were used together, the removal efficiency increased to 90.43% within 9 h. In addition, the results also showed that the composite algicide could remove total nitrogen (TN) and total phosphorus (TP) in eutrophic water. However, the removal efficiency of TP is more evident than that of TN under the same composite algicide doses. Thus, the method would provide an alternative composite algicide to mitigate cyanobacteria blooms using calcium hydroxide and illite in eutrophic water. © by PSP.

摘要：
In order to identify these allelochemicals of ethyl acetate extracts from Portulacaceae and seeds, the chemical components of the extracts were analyzed by gas chromatography-mass spectrometry (GC-MS). The algal inhibitory effects of the extracts were determined by bioassays using Microcystis aeruginosa. 15 kinds of compounds, including fatty acid, ester, ketone, sterol were obtained and 8 identified fatty acids and N-phenyl-2-Naphthalenamine were found to be significantly active against some harmful algae. The inhibitory ratios of the ethyl acetate extracts for M. aeruginosa were 56.1% and 49.4% when the algae were exposed to 20.0 mg/L of the extracts, respectively. The results suggested that these ethyl acetate extracts from Portulacaceae and seeds may serve as environmentally friendly agents for controlling the growth of M. aeruginosa. © by PSP.

摘要：
In recent years, massive water blooms of cyanobacteria occurred in many freshwater lakes and reservoirs, and cause severe water quality problems including scum formation, toxin production, taste and odors, and hypoxia generation. Therefore, a new environmental friendly method was proposed for cyanobacterial bloom mitigation using chitosan and illite. The effects of particle size of illite, addition of illite, addition of chitosan on Microcystis aeruginosa removal was examined through batch experiments. The results showed that the removal efficiency of cyanobacteria had a strong dependence on the changes of particle size of illite, addition of illite, addition of chitosan. The highest removal efficiency, 97.42 %, was obtained under the optimal conditions. This study demonstrated that there were technically viable methods using chitosan and illite to remove M. Aeruginosa cells. © 2017 Universite de Paris VI (Pierre et Marie Curie). All rights reserved.

摘要：
Sodium alginate / graphene oxide/ gallic acid (SA/GO/GA) complex gel beads were prepared and were characterized. Removal efficiency of algae onto SA/GO/GA complex gel beads were investigated with different GO and GA content. The results showed that the removal efficiency of algae from aqueous solutions using SA gel beads were very low, but introduction of GO and GA of complex gel beads could sharply increase the removal efficiency of algae onto by 3 times. The amounts of SA/ GO/GA complex gel beads have significant effect on removal of algae. In addition, for the density algae in the range of 2.17-17.36 cells/mL, there was a linear relation between the removal efficiency of algae and the density algae. This stoichiometric linear relation has directed significance to engineering application in eutrophic waters.
