汽车行业涂装清洗废水除磷处理工艺运行技术研讨

随着汽车涂装工业对油漆喷涂质量的要求不断提升,纷纷增加对未喷涂前工件的表面清洗,导致涂装车间含磷废水处理的水量较大,总磷量多在20～50 mg/L.针对此情况,通过实际运行,不断的优化运行参数和加药量,不仅达到了排放要求,而且也使实际的运行成本降低55％.

Phosphorus cleaning wastewater process in PaintShop technology research

To meeting the paint standards improvement, more and more cleaning waste water are produced. In Paint Shop, phosphorus wastewater treatment is a common. The cleaning waste water quality is bigger. And phosphorus content is between 20 mg/L to 50 rag/ L. Through operation practice and summary of experience, and optimization of operating parameters and dosage, the actual operation cost can be reduced by 55%.
