The invention discloses an unpowered water purification system for a riverfront landscape constructed wetland, comprising a riparian wetland constructed along a lake-land ecotone of a river, lake-pond. The riparian wetland comprises a plurality of alternatively arranged wetland islands and watercourses formed between them. The bottom surface of the riparian wetland is lower than the normal water level of the river, lake-pond, and the upper surface of the wetlands is flush with the normal water level of the river, lake-pond. Plants are planted on the wetlands. A revetment is constructed between the riparian wetland and the river, lake-pond, and its upper surface is between the bottom surface of the riparian wetland and the upper surface of the wetlands. The invention achieves good purification and landscape effects. The purification system has some advantages such as good landscape effects, simple management without energy and power consumption, and thus is durable and stable.

Zinc-air is a century-old battery technology but has attracted revived interest recently. With larger storage capacity at a fraction of the cost compared to lithium-ion, zinc-air batteries clearly represent one of the most viable future options to powering electric vehicles. However, some technical problems associated with them have yet to be resolved. In this review, we present the fundamentals, challenges and latest exciting advances related to zinc-air research. Detailed discussion will be organized around the individual components of the system-from zinc electrodes, electrolytes, and separators to air electrodes and oxygen electrocatalysts in sequential order for both primary and electrically/mechanically rechargeable types. The detrimental effect of CO2 on battery performance is also emphasized, and possible solutions summarized. Finally, other metal-air batteries are briefly overviewed and compared in favor of zinc-air. This journal is © the Partner Organisations 2014.
