【Influence of pH on Water Hyacinth Ponds Treating and Recycling Wastewater】
#论文# #废水净化# #生活污水治理# #水环境#

Their vigorous productivity and their ability to reproduce successfully in new nutrient-enriched habitats make water hyacinth (WH) a good candidate for wastewater purification and nutrient recycling. In this work, the effect of pH on the efficiency of water hyacinth ponds (WHP) in treating domestic wastewater and production of plant biomass is carried out in pilot scale ponds under batch flow conditions.

澳大利亚的Southern Cross矿区是有名的“约瓦果仁欧泊”产地。在那里采矿是一件非常辛苦的差事。因为当地降水极少，植被稀疏，食物和饮用水的获取都非常困难。在约瓦发现的欧泊多是产自铁矿石的结核中。

Opal mining in the Yowah mine is very difficult. With little vegetation and extreme drought, obtaining water and food was difficult. The Southern Cross Mine was the home of the famous “Yowah Nut,” precious opal found in ironstone nodules or concretions.
