摘要
酸洗废水采用石灰中和、混凝沉淀和过滤工艺进行处理,处理后的污泥中含有大量重金属和氟化钙的混合物,属危险废弃物,必须进行环保处理。结合不锈钢公司冷轧酸性废水处理改造对于冷轧酸性废水处理污泥减量化技术进行了探讨。
Acid pickling wastewater is treated by lime neutralization,coagulation sedimentation and filtration process.The sludge after treatment contains large amount of mixture of heavy metals and calcium fluoride,which is a hazardous waste and must be treated in an environmentally friendly way.This paper discusses the sludge reduction technology of cold rolling acid wastewater treatment combined with the transformation of cold rolling acid wastewater treatment in a stainless steel company.
