中山市浩佳印刷厂日处理 3000m³ 废水工程设计中山市浩佳印刷厂日处理 3000m³ 废水工程设计摘 要随着印刷行业日益成熟，印刷废水的污染是成为我国水体污染问题之一。印刷废水具有高 COD、高色度、可生化性差的特点，由于许多印刷厂对其废水处理不完善，水体指标超标，导致印刷废水污染问题日益严重。因此，解决这些问题的关键是运用高效、合理、经济的废水处理工艺，以提高印刷厂末端治理的效率。北京理工大学珠海学院 2020 届毕业设计本设计是中山市浩佳印刷厂日处理 3000m³ 废水工程的初步设计。根据厂区规模，结合印刷废水需提高可生化性、除 COD、脱色的要求，本设计采用“絮凝气浮-水解酸化-生物接触氧化”污水处理工艺。运用絮凝气浮法有效去除污水色度和 SS、水解酸化法可提高污水可生化性、生物接触氧化法具有高稳定性，污泥量少的特点，既可让污水处理流程简化、节省投资，也使该厂印刷废水基本满足广东省《水污染物排放限值》（DB4426-2001）第二时段一级标准的要求。关键词：印刷废水 絮凝气浮法 水解酸化法 生物接触氧化法Engineering Design of Daily Treatment of 3000 m³ Wastewater in Haojia Printing Factory of Zhongshan CityAbstractAs the printing industry becomes more mature, the pollution of printing wastewater has 北京理工大学珠海学院 2020 届毕业设计become one of the problems of water pollution in China. Printing wastewater has the characteristics of high COD, high chroma, and poor biodegradability. Due to the imperfection of wastewater treatment by many printing plants and the exceeding of water body indicators, the problem of printing wastewater pollution is becoming more and more serious. Therefore, the key to solving these problems is to use efficient, reasonable, and economical wastewater treatment processes to improve the efficiency of the end treatment of printing plants.This design is the preliminary design of the daily treatment project of 3000m³ wastewater in Haojia Printing Factory of Zhongshan City. According to the scale of the plant, combined with the req...
