摘　　要：本研究以吐鲁番地区鄯善县氧化塘处理后出水灌溉生态林为案例,分析新疆小城镇生活污水生态利用可行性。选择3个示范点,分别对0.2 m、0.4 m、0.6 m、0.8 m、1.0 m五个深度生态利用前后土壤中有机碳、氨氮、硝酸盐氮、亚硝酸盐氮、盐分等污染物浓度进行监测,研究土壤生态系统对生活污水处理效果。研究结果表明土壤的p H、全盐量、钠离子、氯离子灌溉区较对照区有均有降低,降幅分别为1.9%~6.0%、71.43%~95.71%、97.70%~99.53%、95.76%~98.99%。土壤中的有机质、全氮、全磷含量均较非灌区有所增加,且随土层深度的增加其含量增加量逐渐减少,并呈现稳定趋势。研究区从2008-11月投入使用至今,区域地下水水质无明显变化。This paper analyzes the eco-utilization feasibility of domestic sewage in small towns in Xinjiang by taking ecological forest irrigation after treatment of oxidation pond in Shanshan County in Turpan Prefecture.3 demonstration sites are selected,and the concentration of pollutants such as organic carbon,ammonia nitrogen,nitrate nitrogen,nitrite nitrogen and salt in soil is monitored at five depths 0.2 m,0.4 m,0.6 m,0.8 m,1.0 m before and after eco-utilization respectively,in order to study the treatment effect of soil ecosystem for domestic sewage.The results show that,pH,total salt content,Na+,Cl-in soil in the irrigated area are all reduced compared with those in the control area,with a rate of 1.9%~6.0%,71.43%~95.71%,97.70%~99.53%,95.76%~98.99%respectively.Organic matter,total nitrogen and total phosphorus contents in soil are all increased compared with those in non-irrigated area,and the increment of their contents gradually decreases as the depth of soil layer increases and shows a stable trend.Since Nov.2008 when the study area went into operation to this day,the quality of ground water in the area has no great change.
