含砷废水治理方法的研究进展

Review on Arsenic Wastewater Treatment Technique

分别从化学、物理、生物技术和人工湿地4个方面介绍含砷废水治理方法的工作原理、优缺点及其研究进展。各种含砷废水治理方法都有自身的优缺点,应该针对不同性质的含砷废水研发各种除砷技术的联合技术,提高除砷效率,降低除砷成本。

The principles,advantages,disadvantages and research progress of arsenic waste water treatment techniques from chemical,physical,biological technology and constructed wetland are introduced.Arsenic wastewater treatment techniques has its own advantages and disadvantages,we should develop a variety of composite technologies aiming at different properties of arsenic wastewater to improve the removal efficiency and to reduce the cost.According to the advantages and disadvantages of arsenic wastewater treatment techniques,a combined arsenic removal technology that can remove arsenic from different type of wastewater should be studied for enhancing arsenic removal rate and decreasing the cost of arsenic removal.
