摘要
为了明确长江下游地区农村生活污水排放规律,对长江入海口崇明生态岛A镇的农村地区展开了污水排放调研.结果表明:A镇户均常住人口为 1.55 人/户,人均用水量为 79.5 L/(人·d),平均折污系数为 0.76.农村生活污水中黑水排放量小、污染物浓度高,人均黑水水量占排水量的 29.90%.农村生活污水时排水量、污染物浓度波动较大,7:00-8:00 污染物浓度较高,在 20:00 排水水量达到全天的最大值.全年人均日排水量变化较大、日负荷变化较小,在国庆节、春节等节日人均排水量、负荷较大.研究结果对于长江下游生态岛农村生活污水治理的模式选择、装备研制、提标及资源化模式的探索具有重要意义.
Abstract
In order to clarify the law of rural domestic sewage discharge in the islands of downstream Yangtze River,the research on sewage discharge in the rural area of town A of Chongming eco-island,where the Yangtze River enters the sea,showed that:the average resident population of households was 1.55 persons/households,and the per capita water consumption was 79.5 L/(person-day),and the average discount coefficient of pollution was 0.76.Black water discharge in rural domestic sewage was small,the concentration of pollutants was high,and the amount of black water per capita account for 29.90%of the amount of water discharged.The discharge volume and pollutant concentration of rural domestic sewage fluctuated greatly,with higher pollutant concentration from 7:00 to 8:00,and the discharge volume reached the maximum value of the whole day at 20:00.The daily discharge per capita varied greatly throughout the year,and the daily load varied little,but the daily discharge per capita and load were greater during the National Day and Chinese New Year festivals.The results of this study are of great significance to the exploration of the model selection,equipment development,standardization and resource utilization of rural domestic sewage treatment in the eco-islands in downstream of Yangtze River.
