王洪臣：城镇污水处理厂疫情防控应急对策
摘要：千家万户的污水,包括医院污水,都会直接或间接通过下水道进入城镇污水处理厂,因此,污水处理厂是全社会疫情防控的关键环节。城镇污水处理厂运行工作千头万绪,但在重大疫情面前,应着重处理好两件事情:一是在出现不利因素的情况下确保正常稳定运行;二是严格做好运行操作人员的安全防护。做好这两条就是最成功的应急处置。在整个疫情防控期间,全国5000多座城镇污水处理厂都能排除各种不利因素保持正常运行,让每天产生的两亿多吨污水都得到正常处理,几十万一线运营人员在岗位上不被病毒感染,这就是污水处理行业对全国疫情防控的最大贡献。

王洪臣：关于疫情防控期间医疗污水和城镇污水处理若干问题的建议
摘要： 新冠病毒感染的肺炎存在"粪口传播"可能,因此加强医院污水和城镇污水防控具有重要现实意义。在源头上强化医疗污水消毒处理,选择性优化消毒方式、药剂种类和投加量,确保病毒在源头上得到有效控制;城镇污水处理厂应确保稳定运行,在整体上提升运行保障等级,加大设施设备巡检和水质监测频次;对于城镇污水收集系统,应以防为主,避免扰动;同时,应严格做好不同污水处理系统中工作人员的安全防护。

2020.03.17王明玥等：Impact of scaling on aeration performance of fine-pore membrane diffusers based on a pilot-scale study
ABSTRACT: Aeration systems consume a large amount of energy in wastewater treatment plants. Fine-pore membrane diffusers are most commonly used in aeration systems. Scaling and fouling on these membrane diffusers will lead to decreased performance in aeration and increase energy consumption. This pilot-scale study focused on the scaling of the three kinds of fine-pore membrane diffusers under different influent hardness conditions. The results showed that the diffusers were mainly polluted by ca

ABSTRACT: Tourism can be an important strategy for conserving traditional agricultural systems and potentially enhancing livelihoods of hosting communities. The intricate and complex relations between agricultural heritage conservation, tourism and community livelihoods are examined at a GIAHS site in China. Through multistakeholder interviews, the study illustrates that the increased government support and public awareness after GIAHS designation do not ease the struggle between conservation

ABSTRACT: Herein, we assess the relative potential of singlewalled multi-walled, and graphitized multi-walled carbon nanotubes (CNTs) for the adsorptive removal of organic species using aniline and nitrobenzene as model aromatic contaminants. The obtained results reveal that the adsorption behaviour of aromatic organics is significantly affected by their functional groups (especially when functionalized CNTs are used as adsorbent), providing valuable guidance for adsorption-based removal o

余雨等：单丝滤布优选及悬浮物特性对其过滤性能影响
摘要：根据国标测定单丝滤布的孔径、过水通量及透水阻力,从而优选出过滤性能最优的滤布。探究了悬浮物粒径、浓度及比表面积对单丝滤布过水通量的影响,并采用HERMIA模型分析了单丝滤布的堵塞机理。实验结果表明:悬浮物粒径越大单丝滤布过水通量的下降越明显,过滤后悬浮物中位粒径与滤布孔径的比值均在0.36～0.46;悬浮物的浓度越高、比表面积越小,在滤布表面的架桥作用越强,形成的滤饼层孔隙越小,滤布越容易被污染。 关键词：单丝滤布 过滤 粒径分布 堵塞模型 水处理技术

余雨等：滤布材质及微观结构与透水性能的关系
摘要：机织滤布的透水性能会直接影响过滤设备的生产效率。为理清滤布材质、微观结构与过水通量之间的相互关系,定制一批控制变量的滤布用于实验。对不同材质的滤布进行了FTIR,动、静态接触角和表面能测定,从机理分析了材质影响过水通量的关键性指标。对滤布微观结构进行了SEM表征,并分析了编织方式、厚度、孔径对过水通量的影响,建立了滤布微观结构与过水通量的半经验模型。结果表明:材质亲水性大小顺序为聚丙烯>聚碳酸酯>聚酰胺,对应的过水通量分别为6.34、5.75、5.46 m/min,亲水性强的材质具有更大的过水通量;微观结构中,过水通量大小顺序为缎纹滤布>斜纹滤布>平纹滤布,孔径、厚度分别与过水通量呈正、负相关关系,拟合的微观结构与过水通量的半经验模型可以为机织滤布的选型提供理论参考。
