摘要/Abstract

摘要： 为了解江西省不同地形农村生活污水排放特征，选取山地、丘陵和平原3种地形，分别对农户生活污水的灰水和黑水分时段进行监测，研究农户生活污水排放特征、各指标之间相关性以及影响因素。结果表明，山地、丘陵和平原地形农户人均用水量分别为100.08、96.89、94.52 L/（d·人）。一日内农户污水污染物浓度高峰时段在10：00~14：00（灰水）、14：00~18：00（黑水），不同季节中污染物浓度最大出现在冬季，最低出现在夏季。污水COD、SS、NH4⁺-N、TN和TP的浓度中位值分别为487.5、67.5、19.43、33.85、6.36 mg/L（灰水）和481、76、97.6、146、13.1 mg/L（黑水）。3种地形污水的NH4+N、TN、TP两两间均有极显著的正相关，COD与TN、TP的相关性均显著。地形对污水水质的影响水平较收入水平和户均人数更为显著。研究结果可为江西省农村生活污水治理和生态环境保护提供参考。

Abstract: To analyze the discharge characteristics of rural domestic sewage in different terrains of Jiangxi Province, three terrains including mountainous, hilly and plain, were selected to monitor the gray water and black water of rural residents' domestic sewage.The characteristics of rural residents' domestic sewage discharge, the correlation between each index and the factors affecting the discharge characteristics were studied.The results indicated that per capita water consumption of rural residents in mountainous, hilly and plain areas was 100.08, 96.89 and 94.52 L/（d·cap）, respectively.The peak pollutant concentrations in a day were between 10：00-14：00 (gray water) and 14：00-18：00 (black water), and the maximum pollutant concentrations occurred in winter and the minimum occurred in summer.The median concentrations of COD, SS, NH4+N, TN and TP in effluent were 487.5, 67.5, 3.49, 33.85, 6.36 mg/L (gray water) and 481, 76, 97.6, 146, 13.1 mg/L (black water).A highly significant positive correlation was found between NH4⁺-N, TN, and TP for two of the three terrains sewage, and the correlations between COD and TN and TP were all significant.Terrain demonstrated a larger significance of level of influence on wastewater quality than the factors of income level and average household size.This study can provide reference for the management of rural domestic sewage in Jiangxi Province and ecological environmental protection in Poyang Lake basin.
