采用粉末活性炭(PAC)与超滤组合工艺深度处理黄河源水。结果表明,超滤膜对浊度和藻类的去除效果远好于传统滤池,超滤膜出水浊度基本在0.1NTU以下,对叶绿素a的平均去除率达92%;另外超滤膜对细菌的去除效果也较好,出水中检测不到细菌和总... 采用粉末活性炭(PAC)与超滤组合工艺深度处理黄河源水。结果表明,超滤膜对浊度和藻类的去除效果远好于传统滤池,超滤膜出水浊度基本在0.1NTU以下,对叶绿素a的平均去除率达92%;另外超滤膜对细菌的去除效果也较好,出水中检测不到细菌和总大肠菌群。超滤膜对溶解性有机物的去除效果不好,对CODMn和TOC的平均去除率均仅为23%,对UV254则几乎无去除效果;但PAC的投加弥补了超滤膜的这一缺点,使对CODMn、TOC和UV254的平均去除率分别提高至45%、71%和42%,并大幅降低了水中的三卤甲烷生成势。超滤/PAC组合工艺可有效去除水中的污染物,提高饮用水的安全性。 展开更多

The Zoige wetland is the biggest alpine wetland in the world,and an important water resource of the Yellow River.Due to natural and human factors,the Zoige wetland has been seriously degraded.Existing studies on the Zoige wetland mainly focus on the macro features of the wetland,while the influence of the surrounding faults on the Zoige wetland degradation is rarely studied.This study uses terrain data to analyze the cover change and the water loss caused by the Wqie-Seji fault based on the distributed hydrological model.The simulated water loss demonstrates that the Normalized Difference Vegetation Index(NDVI) is the most important factor for inducing water loss.The fault is also a factor that cannot be neglected,which has caused 33% of the wetland water loss.Therefore,it is of importance to study the influence of the fault on the wetland degradation. 展开更多

The characteristic of the resources are vast, wild. rare, peculiar and fresh. Some natural resources, ecotourism resources on the wetland nature reserve of the estuary, and the special landscape ecology resources are introduced in this paper. The author also suggests that the sustainable development of the travel industry at the estuary should be based on the protection and reasonable utilization of the ecosystem. 展开更多

The changes in hydrological processes in the Yellow River basin were simulated by using the Community Land Model(CLM,version 3.5),driven by historical climate data observed from 1951 to 2008.A comparison of modeled soil moisture and runoff with limited observations in the basin suggests a general drying trend in simulated soil moisture,runoff,and precipitation-evaporation balance(P-E) in most areas of the Yellow River basin during the observation period.Furthermore,annual soil moisture,runoff,and P-E averaged over the entire basin have declined by 3.3%,82.2%,and 32.1%,respectively.Significant drying trends in soil moisture appear in the upper and middle reaches of the basin,whereas a significant trend in declining surface runoff and P-E occurred in the middle reaches and the southeastern part of the upper reaches.The overall decreasing water availability is characterized by large spatial and temporal variability. 展开更多

The incision of the Sanmen Gorge marks the birth of the modern Yellow River,but its timing varies from the late Miocene-early Pliocene to the late Pleistocene(~0.15 Ma),and the suggested forcing mechanisms vary from the uplift of the Tibetan Plateau to global climate change.Here,we report sedimentologic,geochronologic,and provenance data from a drill core near the Sanmen Gorge,the last gorge along the main course of the Yellow River.Our results indicate that typical river channel deposits,with detritus from the Ordos Block in the upstream regions,started to accumulate in the Sanmen Gorge at~1.25 Ma.When integrated with river terrace evidence from the upstream and downstream regions,the results provide robust evidence that the final integration of the modern Yellow River occurred at~1.25 Ma,consistent with the beginning of the Mid-Pleistocene transition(MPT).We propose that the accelerated lowering of eustatic sea level during the MPT may play as important a role as tectonism in driving the birth and evolution of the modern Yellow River. 展开更多
