Phosphorus recovery from municipal and fertilizer wastewater: China's potential and perspective

Phosphorus (P) is a limited resource, which can neither be synthesized nor substituted in its essential functions as nutrient. Currently explored and economically feasible global reserves may be depleted within generations. China is the largest phosphate fertilizer producing and consuming country in the world. China''s municipal wastewater contains up to 293,163 Mg year of phosphorus, which equals approximately 5.5% of the chemical fertilizer phosphorus consumed in China. Phosphorus in wastewater can be seen not only as a source of pollution to be reduced, but also as a limited resource to be recovered. Based upon existing phosphorus-recovery technologies and the current wastewater infrastructure in China, three options for phosphorus recovery from sewage sludge, sludge ash and the fertilizer industry were analyzed according to the specific conditions in China.     

Predicting vehicle fuel consumption patterns using floating vehicle data

The status of energy consumption and air pollution in China is serious. It is important to analyze and predict the different fuel consumption of various types of vehicles under different influence factors. In order to fully describe the relationship between fuel consumption and the impact factors, massive amounts of floating vehicle data were used. The fuel consumption pattern and congestion pattern based on large samples of historical floating vehicle data were explored, drivers'' information and vehicles'' parameters from different group classification were probed, and the average velocity and average fuel consumption in the temporal dimension and spatial dimension were analyzed respectively. The fuel consumption forecasting model was established by using a Back Propagation Neural Network. Part of the sample set was used to train the forecasting model and the remaining part of the sample set was used as input to the forecasting model.     

烟草废弃物快速堆肥过程中重金属Cd形态变化特征

以烟草废弃物为原料,活性土壤为载体建立堆体,研究重金属镉的形态变化,及堆肥过程中的动态变化规律。结果表明,烟草废弃物与活性土壤混合能快速腐熟。堆肥总质量下降,重金属镉含量相对增加。重金属镉的铁锰氧化态比例增加19%,有机结合态比例在堆肥升温阶段增加,腐熟后有所下降。残渣态比例大幅度上升,增加达到5倍,且在腐熟阶段增幅最大。说明堆肥处理有利于降低重金属镉的活性。     

重庆市突发环境事件时空格局及影响研究

基于2009年-2015年重庆市突发环境事件统计数据,研究了重庆市近7年突发环境事件的动态变化趋势、空间分布格局及污染影响特征,讨论了引发突发环境事件内外部因素之间的关系.结果表明:重庆市7年内共发生突发环境事件134起,且呈波动下降趋势,春季和夏季为交通事故和自然灾害高发期;突发环境事件空间上主要集中在主城九区及相邻的区县,渝西、渝东南及渝东北各区县发生次数较少.道路交通事故、设备故障和操作不当是导致突发环境事件的主要因素,主要发生形式为泄漏.污染类型主要为水污染和水气复合污染,污染物出现频率大小为:油类>酸碱类>液氨>苯及其化合物>减水剂>其他各种污染物.
