国内外水泥工业大气污染物排放标准比较研究

新修订GB 4915-2013《水泥工业大气污染物排放标准》于2014年3月1日实施.该标准将成为水泥工业防治污染、减排总量、调整结构、优化布局的重要抓手.本文对我国、美国、欧盟、日本相关排放标准(或指令)进行了研究,对比了污染物项目、控制指标、限值严格程度、实施手段等方面的异同,提出了标准建议,为我国排放标准制修订工作提供参考,有助于提高环境管理和污染控制水平.     

基于条件价值法的行业生态补偿标准的确定——以福建省宁德市石材行业生态补偿为例

生态补偿标准的确定是生态补偿机制建立的难点和重点,在资金供给不足的情况下,做好影响环境质量的关键行业的生态补偿工作尤为重要.因此,本文提出了应用条件价值法确定行业生态补偿标准的思路,并以福建省宁德市敖江流域石材行业为例进行了实证研究.结果显示:2010年福州市民对敖江饮用水安全保障的平均支付意愿为0.21元·t-1自来水,福州市居民愿以自来水费的方式提供3066万元的资金用于敖江饮用水的生态补偿工作.以宁德市石材行业的总产值占宁德市当年GDP总值的百分比(14.4%)作为石材行业生态补偿资金分配的权重,则2010年宁德市石材行业的生态补偿标准为441.50万元.     

Effect of alkalinity on nitrite accumulation in treatment of coal chemical industry wastewater using moving bed biofilm reactor

Nitrogen removal via nitrite （the nitrite pathway） is more suitable for carbon-limited industrial wastewater. Partial nitrification to nitrite is the primary step to achieve nitrogen removal via nitrite. The effect of alkalinity on nitrite accumulation in a continuous process was investigated by progressively increasing the alkalinity dosage ratio （amount of alkalinity to ammonia ratio, mol/mol）. There is a close relationship among alkalinity, pH and the state of matter present in aqueous solution. When alkalinity was insufficient （compared to the theoretical alkalinity amount）, ammonia removal efficiency increased first and then decreased at each alkalinity dosage ratio, with an abrupt removal efficiency peak. Generally, ammonia removal efficiency rose with increasing alkalinity dosage ratio. Ammonia removal efficiency reached to 88% from 23% when alkalinity addition was sufficient. Nitrite accumulation could be achieved by inhibiting nitrite oxidizing bacteria （NOB） by free ammonia （FA） in the early period and free nitrous acid in the later period of nitrification when alkalinity was not adequate. Only FA worked to inhibit the activity of NOB when alkalinity addition was sufficient.     

Application of adaptive heuristic criticism control (AHCC) to dye wastewater

This paper presents an experimental application of AHCC to study the coagulation process of wastewater treatment in a dye plant. Also this study includes a series of tests in which an AHCC control was used for pH control. The performance results of the AHCC controller are compared with the results obtained by using a conventional proportional-integral-derivative (PID) algorithm. It is useful to compare PID with AHCC to illustrate the extreme range of the nonlinearity of the dye wastewater treatment process. Although the removal of pollutants from wastewater is similar with AHCC and PID, our results show excellent AHCC performance in the region where conventional PID control fails.

A multiple timescales approach to assess urgency in adaptation to climate change with an application to the tourism industry

As climate change adaptation is increasingly discussed and becoming a mainstream concept, different types of users are asking themselves if and when they should develop an adaptation strategy, often not knowing where to begin. Climate experts, on the other hand, have access to an enormous amount of data that could be useful to users but often do not know how to translate it into something practical. Both users and experts can be linked through two timescales, the system lifespan and climate vulnerability. While the system lifespan relies on the user’s estimation of his planning timeframe, the climate vulnerability is estimated from climate model projections and observations. We propose a simple tool to relate user and climate expert knowledge by combining the two timescales. To be reliable, the interconnection implies a dialogue to first identify what sensitive climate variable will impact the system and subsequently the extent of the impact. Climate data can then be used to identify, with the use of a simple graph, how sensitive a system is likely to be and help users position themselves about the urgency of adaptation. The concept has been successfully presented and applied to the tourism industry, notably the ski industry, which is showcased in this paper.
