山村生活污水无害化后回灌农林用地是实现污水资源化的有效途径,但其是否会加剧农林氮素面源污染的影响规律尚不明确。以皖西大别山区典型旱地(韭菜)、林地(茶树)和水田(茭白)为研究对象,设置单尾水回灌(SS)、常规施肥(SF)和清水对照(CK)3种处理。经45 d基础培育后,采用人工模拟降雨装置设置0.3、0.6、0.9 mm/min 3个雨强梯度开展降雨试验,系统分析地表径流中总氮(Total Nitrogen,TN)及不同形态氮素的流失特征。结果表明:降雨强度是驱动各类农林用地氮素流失的关键主控因素,随雨强增大,TN及各形态氮流失浓度均显著升高,且流失形态以溶解态氮(Dissolved Nitrogen,DN)为主;不同土地利用类型对尾水回灌的响应存在较大差异,水田中SS处理在各雨强下的氮素流失浓度均低于SF处理;旱地中,SS处理在中、大雨强下TN流失浓度较低,但在小雨强下存在更高的初期冲刷流失风险;林地中,SS处理的各形态氮流失浓度均高于SF处理,氮素流失风险较高。研究表明,山村尾水资源化利用应结合土地利用类型实施差异化管理和面源污染防控措施,旱地应重点防控小雨强初期冲刷风险,林地则建议配套生态拦截措施。
Irrigation of agricultural and forestry lands with harmlessly treated rural domestic wastewater is an effective pathway for promoting wastewater reclamation and resource utilization in mountainous villages. However
whether this practice may increase the risk of nitrogen non-point source pollution in agricultural and forestry lands remains unclear. To address this issue
this study selected three typical agricultural and forestry land-use types in the Dabie Mountains of western Anhui Province: dryland planted with Chinese chives (
Allium tuberosum)
woodland planted with tea plants (
Camellia sinensis
)
and paddy field planted with water bamboo (
Zizania latifolia
). For each land-use type
three treatments were established: treated wastewater irrigation alone (SS)
conventional fertilization (SF)
and clean-water control (CK). After a 45-day basic cultivation period
artificial simulated rainfall experiments were carried out at three rainfall intensities of 0.3
0.6
and 0.9 mm/min. The loss characteristics of total nitrogen (TN) and different nitrogen forms in surface runoff were then systematically analyzed to assess nitrogen loss under treated wastewater irrigation across different land-use types. The results showed that rainfall intensity was the primary factor governing nitrogen loss from different agricultural and forestry land-use types. Increasing rainfall intensity significantly elevated the concentrations of total nitrogen (TN) and various nitrogen forms in surface runoff. Dissolved nitrogen (DN) was the predominant form of nitrogen loss
indicating that runoff-driven nitrogen export was mainly controlled by dissolved-phase transport.The response of nitrogen loss to treated rural domestic wastewater irrigation differed markedly among land-use types. In the paddy field
nitrogen loss concentrations under the SS treatment were consistently lower than those under the SF treatment across all rainfall intensities
indicating that treated wastewater irrigation did not enhance nitrogen loss compared with conventional fertilization. In the dryland
the SS treatment reduced TN loss concentrations under moderate and high rainfall intensities but showed a greater risk of initial nitrogen flushing under low rainfall intensity.In contrast
in the woodland
the concentrations of the different nitrogen forms under the SS treatment were higher than those under the SF treatment
indicating a relatively high nitrogen loss risk associated with treated wastewater irrigation. Overall
these findings indicate that t
he environmental effects of treated rural domestic wastewater reuse are highly dependent on land-use type and rainfall intensity. Therefore
the resource utilization of rural treated wastewater should be guided by land-use-specific management strategies and corresponding non-point source pollution control measures. In dryland systems
priority should be given to mitigating initial nitrogen flushing under low-intensity rainfall. In woodland systems
ecological interception measures should be incorporated into wastewater reuse practices to reduce nitrogen export via surface runoff.
