Influence of Pollutant Removal Efficiency on Natural Ventilation in GPPLF System

Abstract:

Two Gravel-less Perforated Pipe Leach Fields systems with naturally ventilated or not were tested to treat domestic sewage under the hydraulic loading of 3.3 cm/d, and the differences of the two systems decontamination effect were also investigated by using T test. The results showed that the average removal rates of COD_Cr, TP, TN and turbidity were 86.1%, 58.0%, 61.1% and 93.6% in the naturally ventilated system, which was 2.0%, 5.4%, 10.2% and 3.2% higher than the normal GPPLF system under the same operating condition. T test indicated that the system of natural ventilation had little effect on removal of COD_Cr and TP, but could significantly improve the treatment effect of TN and turbidity.
