废纸制浆综合废水治理工程的研究

针对废纸纸浆综合废水的特点,根据生产纸张品种,从源头治起,在生产过程中采取清洁生产工艺,提高废水循环利用率,降低清水用量,为零排放打下了坚实的基础。为了能满足生产需要,在废水治理中采取“物化 生化”的处理工艺,使污水经处理后各项指标均达到国家一级排放标准。

Research for engineering of synthetical wastepaper pulp sewage

In view of the properties of the synthetical wastepaper pulping sewage and the types of the paper ,the cleaning process was adopted in the course of producing .The rate of circulative usage was raised ,the quantity of clean water was reduced ,and the zero drainge was gronnded .In order to satify the need of producing ,the process of "physical chemistry & biological chemistry"was taken in the sewage treatment,so all variety of drainge indexes come up to the first grade standards of country.
