| Abstract: | Fluorine wastewater is generated from production of a solar enterprise in Zhejiang.The amount of wastewater is 2 000 m3/d,and the fluorine ion concentration is 300 to 500 mg/L.The project adopts two-stage reaction precipitation method,with calcium salt precipitation in the first stage,and aluminum salt precipitation in the second stage.The effluent fluorine ion concentration is reduced to below 10 mg/L,meeting the first class criteria specified in the Integrated Wastewater Discharge Standard(GB 8978-1996).The problems of environmental protection for the enterprise are solved. |
