【摘要】 根据糠醛生产废水的特点,利用生产企业所处低洼盐碱地改造成表面流人工湿地,废水在湿地内以自然消耗的方式处理,无外排,处理的废水量等于湿地内废水的自然蒸发量、植物的蒸腾量与植物的贮存量。研究表明,经湿地处理后的废水COD去除率平均为94%,TN去除率平均为65%,TOC去除率平均为94.9%。处理后的废水pH值为6.22。更多还原

【Abstract】 The wastewater of producing furfural was treated with surface flow constructed wetland that rebuilded by low-lying saline and alkaline land bases on the character of wastewater,the experimental method was natural consumption that the wastewater amount was balanceable with natural evaporation and crop evapotranspiration and water content of plant,no draining wastewater.The results showed that the average removal rate of COD was 94%,the removal rate of TN was 65%,the removal rate of TOC was 94.9%,the pH of effluent was 6.22.更多还原
