【摘要】 鸭子每小时每斤体重排干粪1.02克,每只鸭子年排干粪12.22kg。鸭粪中含有大量氮、磷、微生物和耗氧污染物。青浦县每年排放干鸭粪3.28～4.88万吨,松江县为1.25～2.17万吨。其中24％左右进入水体。污染物的单位水面负荷量相当高,特别是磷、氮营养物和微生物污染物。这必然引起水体富营养化和降低饮用水的质量。更多还原

【Abstract】 The average discharge coefficient of dry duck dung is 1.02g/h per kg of duck body, 12.22. kg/year per one duck. Duck dung contents a large quantity of nitrogen, phosphorus, microbe and oxygen consuming matter. About 32800～48800T and 12500～27300T of dry duck dang is discharged every year in Counties Qingpu and Shongjiang respectively, and about 24 of discharged dung enters into water bodies by various ways. The load capacity of the pollutants for unit water area is very high, specially of nitrogen, phosphorus and microbe pollutants. Certainly, this causes the eutrophication of water bodies and lowers the quality of drinking water.更多还原
