小氮肥厂清洁生产审计案例研究

由于生产技术、规模和管理体系的制约,目前我国的大部分小氮肥厂很难达标排放,尤其是废水中的氨氮超标,成为小氮肥最大的难题.本文通过对咸阳氮肥厂开展清洁生产审计的案例分析指出,推行清洁生产审计是企业达标排放的最佳途径,同时本文也提出了在知识经济时代清洁生产对企业技术改造、参与市场竞争的重要性以及企业推行清洁生产需要关注的问题.

Economics analysis of food waste treatment in China and its influencing factors

• Economics of food waste treatment projects at 29 pilot cities in China was examined. • Roles of location, population size, processing technique, and income were studied. • Economic benefits were limited with a profit to cost ratio of 0.08±0.37. • Service population size affects construction economics significantly (P = 0.016). • Choice of food waste processing technique affects operating economics notably. This study examines the economic benefits of food waste treatment projects in China and factors affecting them. National-level pilot projects for food waste treatment located in 29 cities were selected as samples. The economics of food waste recycling from the investors’ perspective, in terms of investment during the construction phase and cost and benefit during the operation phase, was assessed. Results indicate that the average tonnage investment of food waste treatment projects was RMB 700.0±188.9 thousand yuan, with a profit to cost ratio of 0.08±0.37. This ratio increased to 0.95±0.57 following the application of government subsidies. It highlights the limited economic benefits of food waste treatment facilities, which rely on government subsidies to maintain their operations in China. Further analysis using a multi-factor analysis model revealed that regional location, service population size, processing techniques, and urban income exerted varying impacts on the economy of food waste treatment. Population size exerted the highest impact (P = 0.016) during the construction stage, and processing techniques notably influenced the project economy during the operation stage. The study highlights the need to prioritize service population size and processing techniques during economic decision-making and management of food waste recycling projects. The results of this study can serve as a valuable practical reference for guiding future policies regarding food waste treatment and related planning.     

Microbially induced deterioration of architectural heritages: routes and mechanisms involved

Background

This paper deals with the water quality legislation that has been enforced in Palestine over the past century, from the Ottoman era through the British Mandate and Jordanian reign, to the Israeli occupation and current Palestinian autonomy.

Results

The study reveals that, due to the instability and the short interrupted spans of these regimes, apart from the Ottoman era, the successive ruling administrations were unable to draft water legislation in the interest of the Palestinian population, though the more stable Jordanian rule is an exception to this. Moreover, the study shows that the subject of the enacted legislations has depended on the circumstances that the population is subjected to or simply as reaction that deals instantly with a certain problem without taking into account any planning or future socioeconomic development. However, major concerns over the quality of accessible water gained momentum with an ever-increasing demand for limited water resources and the need for water treatment.

Conclusions

Investments in legislation and its enforcement will lead to significant economic development and public health and environmental quality enhancement through equitable and reasonable management of shared water resources and community empowerment and awareness.

社会进入二十一世纪,时代的发展,教育观念的转变,对高校学生的思想政治工作提出了新的机遇和挑战,新的时期,如何做好高校学生思想政治工作,这是摆在思想政治工作者面前的重要课题。笔者认为,创新,是高校思想政治工作的生命所在,既是时代发展、教育向素质教育转轨的客观要求,也是高校思想政治工作本身发展的内在动力。思想政治工作的创新是整体的,只有从思想政治工作的内容、形式和方法上全面创新,才能适应社会发展和人才成长的需要。     

长江中下游湖泊富营养化过程的湖泊沉积记录

长江中下游湖群区，历来是人类最活跃的场所，但由于近年来社会经济的迅速发展，湖泊富营养化问题日趋严重，对湖泊湿地变化与湖泊营养盐状况关系的分析是制定湖泊环境整治和生态修复的重要科学依据。长江中游湖泊——龙感湖的湖中心钻孔沉积物中硅藻组合和总磷变化记录了近百年来龙感湖富营养化过程。沉积物中湿地花粉与人湖营养盐关系以及磁化率的分析表明，流域内人类活动对湖周滩地的改造，破坏了湿地植被，助长了人湖物质的增加，湖泊营养相对富集，而流域农业化肥的使用导致了水质的进一步恶化。

Research on low carbon management using a scientific classification method

This research is aimed at the rapid development of a low-carbon economy, in which we propose the classification and application of relevant management measures to affect the development of environmental management ideas and measures of the low-carbon economy, which we called as low carbon management measures. According to scientific analysis of the lowcarbon economy, we can divide low-carbon management measures into three parts: measures for reduction of carbon sources, carbon flow planning, and increase of carbon sinks. Furthermore, we list the advantages that China can utilize to develop its own low-carbon management measures. In the end, necessary adjustments to environmental management measures in China can be made according to this scientific classification.
