摘要:

采用化学沉降法对贵阳市城市污水进行深度净化,以含锌废酸洗液制备的聚合氯化铝铁絮凝剂(PAFC)去除污水中的磷.TEM及EDS检测表明:贵阳市城市污水中的磷主要以有机生物体形态存在,有代表性的微粒是条状微生物,条状微生物还是重金属锌的富集体.PAFC絮体将条状微生物及黏土矿物碎屑等颗粒物包裹沉降后,污水中的磷与重金属锌也随之被去除.含锌PAFC絮凝剂对贵阳市城市污水的脱磷处理不会带来重金属的二次污染.

关键词: 聚合氯化铝铁, 絮凝, 除磷, 锌富集

Abstract:

Chemical settlement has been used for carrying out the advanced treatment of urban sewage in Guiyang City. Polyaluminum ferric chloride (PAFC) flocculant,which is prepared with zinc-containing waste pickling solution,has been used for removing phosphorus from sewage. TEM and EDS detections show that the phosphorus in Guiyang urban sewage is mainly in shape of organism. The representative particulates are strip-shaped microbes and the strip-shaped microbes are accumulation of heavy metal zinc. After the strip-shaped and rod-shaped microbes and clay mineral crushed granules are wrapped by PAFC flocculant,the phosphorus and heavy metal zinc ion can be removed therewith. The zinc-containing PAFC flocculant doesn’t bring secondary pollution of heavy metal to the dephosphorization treatment of urban sewage in Guiyang City.

Key words: polyaluminum ferric chloride, flocculation, dephosphorization, zinc accumulation
