清远喷漆化工废水处理工程设计方案

工程概况

  清远某塑胶有限公司所排放的废水主要来源于员工生活污水、喷漆废水等,喷漆废水主要来源于喷漆式水帘柜吸收喷雾后产生的废水,生活污水主要含有CODCr、BOD5、SS、NH3电竞押注-N、P等。生产废水含有大量的水溶性油漆,主要含有喷漆颗粒物、有机物、色度、油类等物质,该废水经过一定时间的循环使用后,水中污染物累积,污染物浓度较高,其COD值可高达10000mg/L以上,一般需要更换新鲜水。该废水成分较复杂,难以被生物降解,该喷漆废水的主要特点是: 有机物浓度高、水量水质变化大,生物降解效率低,缺乏营养物质等特点。该废水若不经处理直接外排,将会带来严重的污染。

  对于喷漆废水,目前只有一座循环水池,现计划投资对喷漆废水进行处理,对现有循环水池进行改造,经改造处理后废水排放部分可以达到广东省地方排放标准《水污染物排放限值》(DB44/26-2001)第二时段一级标准。现公司水帘柜循环水量126m3/h,间歇排放水量200T/月左右,即6.7T/d;生活污水水量40T/d。水帘柜循环水通过添加除漆剂后回用于生产线上。本项目主要是针对排放部分的喷漆废水、生活污水处理进行设计,项目拟设计处理规模为48T/d。本工程主要采用“预处理+水解调节+UASB+接触氧化”处理工艺,该工艺具有处理效率高、投资低、运行费用低、运行稳定、有沼气产生等优点,可确保出水稳定,长期达到一级排放标准。
