摘要
合肥地区人均洗衣粉用量为 3.12 kg/ a,洗衣粉总用量为 8345 t/ a,洗衣粉带入水体的总磷量为 2 5 6 .0 8t/ a,占入湖总磷负荷量的 13.6 2 %。因此 ,实行“禁磷”措施后 ,可削减该地区入湖总磷负荷量的 13.6 2 % 。
Based on the investigation of phosphorus in detergents and other phosphorus sources in Hefei region of the Chao Lake, the total phosphorus which takes place in the Hefei region, is 1880.24 t/a. About 21.60%(406.21 t/a) of the total phosphorus from Hefei region enters into the lake finally. The total phosphorus in detergents is 256.08 t/a, and which enters into the lake 55.31 t/a. The contribution rate of detergent\|phosphorus to the total input phosphorus is about 13.62%. Therefore, the measurement of phosphorus\|ban in detergents which has been brought in effect in the whole basin of Chao Lake cuts off 13.62% of the total phosphorus which entering into the lake. These will lighten the eutrophication status, delaying the algae break out, and improving the water environment in Chao Lake.\;
