Experimental Study on the Treatment of Sewage by Soil

Article Preview

Abstract:

The bath static experiments were conducted to study the sewage treatment effects by the typical yellow-brown soil of Xuzhou, the results obtained in this study showed that: The COD removal rate was about 50% or so through experimental treatment. The three days dynamic and intermittent soil column experiments show that: The COD removal rate was more than 80% by the simulated soil column experiments; the dynamic intermittent and soil column experiment both show that soil thickness influence the effect of phosphorus removal, the thicker layers, the better removal rate; the effective depth of NH4-N removal is deeper than 15cm.
