透水混凝土生态膜法处理城市生活污水

Research on technique of urban sewage treatment with porous concrete eco-films

采用水泥、碎石、粉煤灰及活性材料CRLT-1等制作了不同配比的透水混凝土生态膜,利用原子吸收仪测定其在水体中的离子溶释过程,并通过渠式反应系统对该透水膜进行了生物挂膜和污水处理实验.实验结果表明,经过这种透水混凝土膜法处理后的污水中化学需氧量(CODC r)的浓度可达到国家相关排放标准.

Porous concrete eco-films have been created out with cement,crushed stones,coal ash and the activated material CRLT-1.The dissolving process of ion released from the eco-films to water has been detected with an atomic absorb detector.With a cannel reactor system,bio-films have been cultivated on the surface of the concrete films,and these films have been adopted to purify sewage.The experimental result shows that the concentration of COD_(Cr) in the outflow from the treatment process can reach national rele...
