Abstract： |
This invention discloses seepage biological bed purification system for polluted river. The purification system comprises: a pool constructed along riversides with a water inlet pipe and a water outlet pipe. Along the river flow direction the pool is divided into three zones. The first zone is filled with cobbles, the second is filled with waste bricks and waste ceramics, and the third is filled with zeolite. On the front end of each zone is set a buffer plate, and on the back end is an overflow weir. At the bottom of each zone is a penetrated aeration pipe. The said wastewater is introduced into the pool through the water inlet pipe, and passes through the three zones after aeration. The purification system can effectively remove organic matters, P and N pollutants in the wastewater, and has abundant raw materials. Besides, the purification system can ensure a long term and stable operation, thus having potential applications in river treatment field. |
