【摘要】 本文利用高碳石墨生产中产生的酸废水制备无机混凝剂——碱式氯化铝 ,取得较好效果 .其产品各项指标均符合有关标准 ,混凝效能与市售碱式氯化铝相比相差无几 ,并且在相当宽的 p H范围内均有较好除浊效果 .且由于产品本身含有 Fe2 + 、Fe3+ ,其混凝效能高于同类低铁或无铁的混凝剂更多还原

【Abstract】 The paper is a resarch into recovery to acidic wastewater from the process of producing high carben graphite.We made use of HCl in the waste water to manufacture basic alumium Chloride (BAC) by means of adding waste alumium powder and got a good effect.Coagulation experiments indicated that product BAC had good coagulation effect in a broad pH range.It’s as good as industry BAC.更多还原
