轻质球形水处理滤料的研制

以粘土为主要原料，加入适量的化工原料，生产出较理想的水处理滤料－一种轻质陶粒。该滤料有强度大、空隙率大、比表面积大、化学稳定性好、生物附着力强、挂膜性能良好、水流流态好、反冲容易进行的特点。通过曝气生物滤池处理城市污水的试验表明，这种滤料具有很好的处理效果。

Development of the slight Global water Filter Material

The paper introduces an ideal water filter material which is produced with clay as raw materal and adding some appropriate industrial chemicals,and has a series of property such as higher strength,higher porosity,more specific surface area,higher chemical stability,higher adhesive force with organisms,better film adhesion,better flow fluid state and successful bounce-back.As a rsult from the treatment experiment of waste water with biological aeration tank,the filter material possesses significant efficiency.
