光伏行业含氟废水处理

摘要

太阳能光伏电池作为一种清洁能源，应用前景广泛。其生产废水因含有F-，腐蚀性强，治理困难。采用两级反应沉淀法，先添加氯化钙除氟，再加絮凝剂和助凝剂进行沉淀，在一级、二级沉淀池中分别进行沉降。结果显示，出水F一质量浓度降至10mg／L以下，达到《污水综合排放标准》（GB8978-1996）的一级排放标准，解决了企业废水处理问题，废水处理效果好，运行稳定，具有推广价值。%Photovohaic cell as a source of clean energy, is more and more widespread. The wastewater from this industry, due to the presence of F-, and highly corrosion resistance, is difficult to deal. The two-stage reaction precipitation method with calcium salt plus PAC/PAM precipitation is used to treat the fluoride wastewater that is generated from production of a photovohaic enterprise in Shanxi. The fluorine ion concentration in the effluent is reduced to below 10 mg/L, meeting the first class criteria specified in Integrated Wastewater Discharge Standard ( GB8978-1996), The problems of environmental protection for the enterprise are solved, and this wastewater treatment technology have high effectiveness, stable operation and practical value.
