@@@@A bio-ecological chain purification system , which integrates and optimizes physical settlement , immobilized microorganisms, aeration by solar energy, and artificial wetlands, was constructed in this study.A demonstration project, with a treatment capacity of 4 000 m 3/d, was constructed in the Liuxiangying Village of Jixian County, in Tianjin.The monitoring results over nearly one year show that , despite of the unstable and high concentration of pollutants at the inlet , this technology can remove 95.4%to 99.6%of TP, 84.53%to 96.74%of COD, and 88.03% to 97.98% of TN.The water quality at the outlet reached grade IV of the surface water standards.The technology meets the requirements of simple and convenient maintenance , low investment, and low energy consumption.The operation cost was less than 0.15 yuan per cubic meter.
