Application research of constructed wetland treatment with nano materials for a rural middle school in Qingdao

Abstract

ABSTRACTA 24 m3/d waste water treatment station including structures, buildings, and non-standard equipment was designed. The design considered the current situation that the wastewater discharged without any disposal of the rural middle school. It also combined with the provisions of the relevant national environmental protection, and was strictly in accordance with the relevant effluent discharge standards and design requirements. The process of vertical subsurface flow constructed wetland system with nano materials was adopted after comprehensive consideration of various factors. The operating cost of the wastewater treatment system is mainly a small amount of electricity bills, which is no more than 0.1 RMB per ton wastewater. The advantage of the project is based on biological treatment as the main technical route and low operating cost. Project commissioning condition and the treatment effects are good.
