摘要:

针对含盐废水蒸发处理工艺复杂、效率低、成本高等问题,利用纺织品具有孔隙率高、透气性好、传湿快和光热转换性能可控等特性,将其作为含盐废水的流动以及蒸发载体进行实验,研究其厚度、透气性、颜色和纳米碳化锆后整理对含盐废水蒸发速率的影响。结果表明:含盐废水在织物表面的蒸发速率比在自然状态下蒸发提高了400%;厚度为0. 48 mm 的织物相比于1. 32 mm 的织物,含盐废水蒸发速率提高了63%;透气率为126. 7 L/ (s·m2 )的织物相比于53. 9 L/ (s·m2)的织物,含盐废水蒸发速率提升了56. 9%;黑色织物对含盐废水蒸发速率的促进作用相比于白色织物提高了30. 3%;采用纳米碳化锆整理后白色织物表面含盐废水的蒸发速率相比未处理织物提升了95. 3%。

Abstract:

Aiming at the problems such as complexity, low-efficiency, and high-cost in evaporation treatment of saline wastewater, textiles were used as the flow and evaporation carrier for saline wastewater, which are featured by high porosity, air permeability, fast moisture transfer and controllable photothermal conversion performance. Experiments were conducted to study the effects of the thickness, air permeability, color and nano-zirconium carbide finishing on the evaporation rate of saline wastewater. The results show that the evaporation rate of the saline wastewater on the fabric surface is increased by 400% compared to the natural state. The evaporation rate of the saline wastewater with a thickness of 0. 48 mm fabric is increased by 63% compared to that of a 1. 32 mm fabric. The evaporation rate of the fabric with air permeability 126. 7 L/ (s·m2 ) is 56. 9% higher than that of a 53. 9 L/ (s·m2 ) fabric. Black fabrics have a 30. 3% increase in promoting the saline wastewater evaporation compared to white fabrics. The evaporation rate of saline wastwater on surface of the white fabrics treated with nanozirconium carbide is increased by 95. 3% compared to the original fabric.

Key words: saline wastewater, evaporation rate, fabric thickness, fabric permeability, nanozirconium carbide
