摘要
为研究汉中市农村居民生活水污染物在全国范围内的赋存特征及其对环境的污染负荷,测算农村居民生活污水的排放系数,通过实地采样与问卷调查的方式收集数据并采用排污系数法核算了汉中市地区居民污染物排放量。结果表明,受地理地貌、人均日用水量、经济状况、年龄组成和日用餐次数等因素的影响,汉中市不同区域居民的生活水污染物的排放系数有所不同;村处理设施对化学需氧量、五日生化需氧量、氨氮、总氮和总磷的去除率效果显著,但对动植物油的去除效率不明显。调研可为陕西省首次进行的农村生活源水污染物排放量的核算提供数据支撑,进一步健全我国生活污染源信息数据库。
In order to study characteristics of domestic water pollutants of rural residents and pollution load to environment in Hanzhong city,discharge coefficient of rural residents'domestic sewage was measured.Results showed that discharge coefficient of domestic water pollutants in different areas of Hanzhong city were different due to factors such as geographical features,daily water consumption per capita,economic status,age composition,and number of daily meals.Village treatment facilities had significant effects on COD,BOD5,ammonia nitrogen,total nitrogen,and total phosphorus removal rate,but removal efficiency of animal and vegetable oils was not obvious.Survey could provide data support for first calculation of rural domestic water pollutant discharge in Shaanxi province,and further improve information database of domestic pollution sources.
