某硫铁矿酸性废水处理工程污泥回流比工艺参数的实验研究

Experimental study on technological parameters of sludge reflux ratio in an acid mine wastewater treatment project

污泥回流比是工程设计、项目建设和项目运营的关键技术参数之一,本文就某硫铁矿矿山酸性废水处理项目进行实验研究,确定工艺最佳污泥回流比应在15%~20%之间,比较经济合理,可节约13%以上的石灰消耗量,为项目设计、建设和运营提供重要依据。

Sludge reflux ratio is one of the key technical parameters of engineering design,project construction and project operation.This paper conducts an experimental study on a pyrite mine acid wastewater treatment project to determine that the optimum sludge reflux ratio should be 15%-Between^20%,it is more economical and reasonable,which can save more than 13%of lime consumption,and provide an important basis for project design,construction and operation.
