As the pollution control project carrying out in the drainage network of branches Yuejinhe

Chenxiangbang

and Xidahebang of Wujingang River

the pollution control technology was explored and researched by applying ecological restoration technics

ODBP for rural house-hold wastewater

combination ecological treatment(ET)of biochemical and ecological systems respectively in the three rivers.Comparing the treatment effects of three pilot projects

the pollution control techniques suitable for the area with drainage network were established.The effects demonstrated that the three techniques can effectively remove the nitrogen

phosphorus and other pollutants in the water with good ecological landscape.After further study and technical optimization

it can become a key technology applied in the improvement of the environment and ecological restoration in the similar area of Taihu Lake basin.
