摘要
汽车涂装废水具有成分复杂、水质波动大、COD值高、可生化性差等特点,采用物化+生化相结合的方法,先在物化阶段,选用合适的混凝剂,通过絮凝反应,去除可沉淀污染物;在生化阶段,通过水解酸化或加营养物,提高废水的可生化性,然后通过好氧生化处理,有效的解决了涂装废水的污染问题。
The wastewater from automobile painting contained high COD, which is poor in biodegradability. Most pollutant can be handled by using appropriate flocculants in stage ofphysieal chemistry. In stage of biology chemistry, firstly, advance biodegradability by hydrolytic and acidation, then, the problem of wastewater from automobile painting can be solved through the treatment of biology chemistry with oxygen.
