摘　　要：含铬污水进入混合较好的稳定塘系统时,铬在其中累积,其累积规律可用如下数学模式描述: 稳定塘系统能较好地去除污水中的铬。被去除的铬主要转入塘底沉积物中。塘中放养凤眼莲能提高除铬效果,因为放养凤眼莲能使铬更充分有效地沉降。能否充分地运用有利于悬浮微粒聚结沉降的技术和措施,是设计除铬或类似重金属稳定塘系统成功与否的关键之一。When wastewater containing, chromium comes into a well-mixed stabilization pond, Cr accumulates in it with such a mathmatical formula:Stabilization pond can remove Cr from wastewater efficiently. Most of the Cr removed deposits. It improves the removal efficiency to plant wa-terhyacinths in a stabilization pond, mainly due to that waterhyacinths improves the sedimentary efficiency of suspended substance in the water.How to make sufficient use of the methods and technologies to help suspended substance deposit is one of the keys to design a successful stabilization pond to remove chromium (or other similar heavy metals).
