Background: The outbreak of COVID-19 has continued to threaten the existence of the human race. The novelty and unstable epidemiologic pattern of the virus had generated so much concern among the global health experts. These concerns were found to be escalated among the frontline health care workers to the extent of impeding the timeliness of the response activities. To slow down the spread of the already established community transmission through the surveillance activities, the concern of the health workers at the community level needs to be addressed. Therefore, this study assessed the concern about COVID-19 pandemic among primary health workers in Oyo State, Nigeria. Methods: This was an online cross-sectional survey conducted among primary health care workers in Oyo State between March and April 2020. Using a two-stage sampling technique, we recruited 284 respondents. A semi-structured questionnaire linked to the Google form was used to collect data. Data were analyzed using IBM SPSS version 25;bivariate analysis was done using Chi-square and binary logistic regression was used to identify the predictors of health workers’ concern at 5% level of significance. Results: The mean age of respondents was 45.0 ± 9.0 years. The proportion of the respondents who had good knowledge of COVID-19 was 52.5%. In the domains of concern, 66.9%, 53.2%, 51.4%, and 46.5% of the respondents expressed government-related, self-satisfaction related, work-related and social-status related concerns respectively. Male respondents were less likely to express concern about COVID-19 compared with their female counterparts (aOR = 0.39, 95% CI = 0.20 - 0.76). Nurses/midwives (aOR = 0.21, 95% CI = 0.05 - 0.85) had lesser likelihood of expressing concern about COVID-19 while middle staff (aOR = 2.5, 95% CI = 1.18 - 5.39) and income earner of ≥N200,000 (aOR = 2.3, 95% CI = 1.34 - 3.92) had higher likelihood of

Background: Worldwide, the burden of cardiovascular (CV) risk factors is rising with devastating impacts on the productive workforce. In developing nations, it has further led to an unstable population pyramid as a result of premature deaths of her workforce leading to the continued tapering of the pyramidal apex. Inspite of this, many studies were conducted among the general population neglecting the local government civil servants who are seen as policy implementers. Therefore, the study assessed the pattern of CV risk factors in South-western Nigeria. Methods: A cross-sectional study was conducted among 260 local government workers selected by multistage sampling technique from July to September 2017. A pretested, interviewer-administered questionnaire was administered to obtain socio-demographic and behavioural information. Lipid analysis, anthropometric, blood pressure, fasting blood glucose measurements were done according to protocols. Data were analyzed using IBM SPSS version 25;bivariate analysis was done using Chi-square. Level of significance was at 5%. Results: The mean age of respondents was 46.0 ± 6.7 years. The proportion of participants with good knowledge of risk factors was 57.7%. The proportion of respondent with hypertension, visceral obesity, general obesity, diabetes, smoking and physical inactivity was 40.4%, 35.0%, 52.2%, 38.2%, 5.8% and 75.8% respectively.

以给水处理厂产生的铝污泥为研究对象,考察其对磷的吸附特性及陈化时间的影响。结果表明,铝污泥对磷的吸附容量主要受p H值的影响,当p H值由4.3升至9.0时,磷吸附容量由3.57 mg/g降为0.74 mg/g;水解试验结果显示,铝污泥中含有羟基、氯离子、硫酸根离子及腐殖质等;吸附过程中,伴随着磷酸根浓度的下降,p H值、氯离子、硫酸根离子及腐殖质呈上升趋势,表明铝污泥对磷的吸附机理主要是配位体交换。在540 d的陈化过程中,傅里叶红外光谱、X射线衍射及SEM分析结果表明,铝污泥的结构、官能团和表面形貌均未发生明显变化,表明陈化时间对铝污泥吸附磷的性能并无显著影响。

Sixteenth International Water Technology Conference

作者： Kiran Tota-Maharaj Piotr Grabowiecki akintunde babatunde Prasad Devi Tumula University of Salford Manchester Civil Engineering Research Centre Newton BuildingSalfordGreater Manchester United Kingdom Institute of Geophysics Polish Academy of SciencesWarsaw Poland Centre for Water Resources Research School of Arch.Landscape and Civil Engineering Newstead Building University College DublinIreland

The integration of constructed wetlands or natural wetlands and surface water heat pumps(SWHPs) leads towards the development of a novel sustainable technology treating urban stormwater and application of renewable energy technologies. SWHPs are a well-recognised source of renewable energy and provide high efficiencies for heating and cooling by employing the enormous renewable storage capacity of surface water systems such as wetlands. Engineered wetland systems are compact urban wastewater or stormwater treatment systems that encompass a plurality of treatment modules similar to processes occurring in natural wetlands. Wetlands are a preferred stormwater treatment system over conventional systems which are energy intensive and inadvertently contribute to greenhouse gas emissions. The incorporation of SWHPs within constructed wetlands has great potential for addressing global water and energy issues, providing significant and multiple benefits for energy and water usage, protecting and enhancing natural water systems within urban catchments and reducing the demand on potable water supplies by contributing to water recycling. Two experimental rigs simulating real-life scenarios of surface water heat pumps integrated with constructed wetlands were set up, and running in a green house(controlled environment) at The University of Salford Manchester. Temperatures and water quality analyses measured the treatment performance and water quality efficiency for the combined systems. The water quality analyses for treatment processes of the rigs showed no significant differences for the removal of biochemical oxygen demand, chemical oxygen demand, nutrients(phosphates, nitrates and ammonia) for the wetland system linked to water-sourced heating and cooling and the stand-alone constructed wetland.

在人工湿地污水处理过程中，铝污泥泥饼可作为湿地植物生长的基质以及微生物膜附着生长的多孔载体。经过对铝污泥人工湿地系统的深入研究，旨在阐明此类人工湿地应用的主要关键问题：①铝污泥是否适用于人工湿地？②铝能否从铝污泥中滤出？③铝污泥在湿地中的使用寿命有多久？④磷是否可以从使用过的铝污泥中回收再利用？⑤是否会有堵塞现象的发生，该如何解决？结果表明：从物理、化学测试结果来看，铝污泥是一种适合的人工湿地填料；湿地系统出水中铝确有滤出，但这只发生在试验最初的10—14d之内，且浓度大大低于饮用水准则中规定的限值；铝污泥在人工湿地中的使用寿命为4～17年；从使用过的铝污泥中提取磷是可行的；湿地在运行中会发生堵塞，可考虑采用系统轮空休息及替换为反粒度砾石床延缓堵塞。
