摘要
目前的城市废水处理方法有活性污泥法及粉末活性炭投料———活性污泥法 ,但两者皆存在不足之处。凹凸棒石具独特的结构和良好的吸附、脱色、净化和过滤性能。通过实验对其用于城市废水处理作了技术可行性研究 ,并进行了相应的经济可行性分析 ,认为凹凸棒石粘土可替代粉末活性炭处理城市废水且成本很低。
The present two methods of treating the urban sewage are activated mud and powder activated carb on material——activated mud, bud the two methods are both deficient. Attapulgite is characteristic of unique textures and fine performance of absorption, discolo ration, purification and filtration. Tec hnical feasibility study as well as some economic feasibility analysis have been made on its use in urban sewage treatme nt. The author thinks it possible to rep lace powder activated carbon with attapu lgite in the treatment of urban sewage, and it is of lower cost.
