摘　　要：本文通过实验室、沉砂池静置、沉淀池沉淀实验研究,结果表明:台兰河河水悬浮物含量很高,主要是细颗粒,在实验室静置40 h,才能满足注水水质悬浮物含量要求(20 mg/L)。沉淀池静置沉淀10 h,悬浮物含量降低至50 mg/L,再延长时间,沉淀效果不明显,最多能够降低到30~50 mg/L。水体悬浮物含量以180 mg/L为界,高于它时,悬浮物中粗粒含量比较多,沉淀比较容易。低于它时,悬浮物中主要是细粒成分,沉淀比较困难。实验结果为台兰河地下水库蓄洪补清的人工补给方案探索了可实施的符合实际的方案。This paper uses static precipitation in laboratory and sedimentation experiment in grit chamber, the results show that, suspended solids content of Tailan Rive is high, mainly fine particles.After standing in the laboratory for 40 hours, it can meet the requirements of water injection water suspended solids content(20 mg/L). The sedimentation tank is left to settle for 10 hours, and the suspended solids content is reduced to 50 mg/L. If the time is prolonged, the sedimentation effect is not obvious, and the maximum can be reduced to 30~50 mg/L.The content of suspended solids in water is limited to 180 mg/L. When it is higher than that, the content of coarse particles in suspended solids is relatively large, and precipitation is easier.Below it, the suspended matter is mainly fine particles, and precipitation is more difficult.The experimental results explore a practical and practical scheme for the artificial replenishment scheme of flood storage and replenishment in the Tailan River underground reservoir.
