【摘要】：河南某造纸企业主要生产废水为纸浆清洗工序产生的中段废水,随着造纸原料结构的改变和新排放标准的颁布实施,该企业需对原有废水氧化沟处理工艺进行改造。简要介绍了原有工艺运行情况、工艺改造思路(在预处理和好氧处理之间增设厌氧处理系统,末端增设化学处理系统)、改造工艺的设计参数及改造后的工艺运行情况。改造后出水水质可以满足《制浆造纸工业水污染物排放标准》(GB 3544—2008)。
[Abstract]:The main wastewater produced in a papermaking enterprise in Henan Province is the middle stage wastewater produced by pulp cleaning process. With the change of raw material structure and the promulgation and implementation of new discharge standards, the original wastewater oxidation ditch treatment process should be reformed. This paper briefly introduces the operation of the original process, the idea of technological transformation (adding anaerobic treatment system between pretreatment and aerobic treatment, and chemical treatment system at the end), the design parameters of the revamped process and the operation of the modified process. The treated water quality can meet the discharge standard of water pollutants in pulping and papermaking industry (GB 3544-2008).
