【摘要】 采用生物膜法分别用棒状活性炭和炉渣作载体,处理城市污水。对比实验结果发现,活性炭和炉渣对CODcr,SS均有良好的去除效果,运行稳定的情况下CODcr去除率均可达80%以上,并且pH也有较大变化。炉渣对水中的有机物、难溶物具有良好的吸附作用,可在一定程度上取代活性炭,降低水处理的费用。更多还原

【Abstract】 Bio-film was used for advanced treatment of municipal sewage. Virgulate activated carbon and slag was respectively used as stuffing. Contrasting the result of the experiment, both CODcr and SS can be removed effectively. Both removal rate of CODcr can abtain 85%. Use slag as the stuffing can effectively reduce the cost of water treatment and at the same time it can guarantee the effect. In a short word, this technology has significant social, environmental and economical benefits.更多还原
