As a promising solar energy conversion technology, solar water evaporation has been regarded as an energy-efficient approach to alleviate the freshwater shortage caused by industrial water pollution. In this paper, we developed a straightforward method with a solar-driven steam generator (SSG) based on the carbonized green algae (CGA) as a light-to-heat conversion material (LHCM) to deal with the industrial wastewater of gold smelting. CGA SSG exhibited excellent light absorption, hydrophilicity, and water evaporation rate (1.66 kg·m·h). It accomplished the non-selective removal of heavy metal ions (Cu, Pb, Zn, Hg) and CN in the treatment of gold smelting wastewater, and the ion removal rate was 99%. Compared with traditional and complex wastewater treatment technologies, the solar-driven CGA SSG presented many advantages (low cost, simple preparation, and high performance) in water purification, which could be employed in backward areas to obtain clean water.
作为一种有前途的太阳能转换技术，太阳能水蒸发被认为是一种节能的方法，可以缓解工业水污染造成的淡水短缺。在本文中，我们开发了一种基于碳化绿藻（CGA）作为光热转换材料（LHCM）的太阳能蒸汽发生器（SSG）的简单方法，以处理金矿冶炼工业废水。CGA SSG 表现出优异的吸光性、亲水性和水蒸发率（1.66 kg·m·h）。它在处理金矿冶炼废水中完成了对重金属离子（Cu、Pb、Zn、Hg）和 CN 的非选择性去除，离子去除率为 99%。与传统和复杂的废水处理技术相比，太阳能驱动的 CGA SSG 在水净化方面具有许多优势（低成本、简单制备、高性能），可在落后地区用于获取清洁水。
