Due to the influence of human, industrial and agricultural activity, a large amount of toxic and harmful heavy metal enter into the soil environment. Heavy metal can easily bio-accumulate through food chain, which cause serious damage to human health. Phytoremediation emerges as a new technology in exploration of effective methods for remediation and rebuild of heavy metal contaminated soils. Although phytoremediation shows great potential in remediation of heavy metal contaminated soil, there still exists many problems in practical application. This article analysis the problems existing in phytoremediation, summarizes the research progress of the technology in application from all the perspective of phytoremediation processes.

Infrastructure is the backbone of the US economy and a necessary input to every economic output [1]. The cost of infrastructure maintenance and management demands significant expense for government and private companies. Infrastructure owners want to increase efficiency and improve their bottom-line from existing infrastructure rather than building new ones [2]. One of the significant challenges for the engineering community has been adopting new technologies such as low-cost wireless smart sensors, augmented reality, Unmanned Aerial System (UAS)-based Structural Health Monitoring (SHM). To receive first-hand insight from infrastructure owners, industry professionals and researchers, a workshop entitled ‘Infrastructure, Maintenance and Management Using New Technology’ was conducted in Fort Worth, Texas. In this paper the findings from the workshop are discussed. Stakeholders highlighted safety of the bridge inspectors as the priority in the maintenance and management work. Based on the findings of this workshop it now clear that adopting new technologies leads to higher safety for field inspectors. Key aspects include importance of new technologies for obtaining actionable data for maintenance and management, owner’s perspectives on development of future technologies, current research progress and challenges faced by infrastructure industry in implementing new technologies are presented.

The traditional water treatment technologies mainly include physical reparation technology, chemical remediation technology and biological-ecological restoration technology. However, there are many limitations in practical application, especially for heavy polluted river. For this reason, it is extremely urgent to explore new technology and method on river ecosystem restoration. The materials of artificial plants are limited to the factors of water transparency, possesses acid and alkali-resistant, resistance to staining and flexibility. The characteristics of artificial plants are low in investment, effective and no secondary pollution. Therefore, it has a broad prospect of application in water treatment. In this paper, the detailed review and application of artificial plants were involved in order to provide theoretical basis for more widely used of artificial aquatic plants.

Downhole Gas Compression (DGC) is an entirely new powered artificial lift technology specifically for natural gas wells. The technology offers the opportunity to increase production by 30-50%, significantly improve reserves and delay the onset of liquid loading. Key application of DGC is for use in deeper partially depleted reservoir wells encountering liquid loading. The research progress of DGC is introduced in this paper and the results of theoretical and experimental study of DGC are investigated. Moreover, the adaptability and application prospect of this new technology is analyzed. There are many gas fields in China faced with problems about effective drainage and recovery enhancement, such as the mature gas fields in Sichuan and Ordos Basin. DGC will have a good application prospect in China and further study of the DGC technology is recommended.
