养鸭场废弃物对湖泊水体的污染及卫生防护对策探索

Approaching the Contamination of Lakes Waters by Abandonee Material from Duck Fame and Its Measures of Hygenical Protection

选择滇池水体为对象,在某养鸭场滇池放鸭区及其上下游水体1.2km^2湖面上设22个监测点,以三氮、三氧及微生物为评价参数,于1989年滇池低水位期采样3次,测定上述污染指标。通过对测定结果的断面及二维空间分析,揭示了养鸭场废弃物对湖泊水体的污染范围、程度及变化规律。同时,对湖泊水体的卫生防护对策作了探索。

The object selected is Dianchi waters, 22 monitoring sites are set upon the lake suface range 1.2km2 aurrounding the ducks and its upper and lower waters. Targets selected are NH4+N, NQ2--N, NO3--N,DO,COD, BOD6, Bacterial total number and total group of Eacherichia coli. In 1989, we've taken samples three times for examination and test the concertrati-ons of the above contaminants, and Do content. To determine results we've ado ted statistical analysis at cross and vertical section, and drawn up two dimensional distribution graph. It show the cont-aminative range, contaminative extent to lakes waters by abandoned materials from duck farm, meanwhile and also the regular Pattern of con -taminants/changing in waters. We've approached the measures of hygenical Protection against lakes waters.
