再生纸与印染废水综合治理技术开发与应用研究

以再生纸造纸废水和印染废水的混合后的水样,采用“混合调节,絮凝反应、斜管沉淀生产接触氧化、二次沉淀、出水的流程处理工艺,并对传统曝气装置的曝气方式等进行了改进,应用效果表明两废水混合后ＰＨ呈中性,利用后序废水处理工艺;

Research on comprehensive trentment technology development and application of tegeneration paper and dyeing waste water

Regeneration paper and dyeing waste water conpsite waste water sample, taking "mixing reguation, floeculation, incilined tubesetter, biologied contact oxidation process, secondary sedimentation basin, drain water" flow diagram treate. Aerating quomodo of conventional aerating settling had mend, application effect showed: 1.Two waste water composited pH showed neutral, in favor of postposition waste water treatment technique; 2.Residual chlorine of regeneration paper carring signeficance influence dyeing waste water decoloration, at one time great residual chlorine content of waste water not to ment biochemical treatment, achieved to control waste water in wasre, inproved composete waste water bichemical treatment; 3.Composite waste wqter was treated by improved waste water flow diagram, this drainning wqater quality meeted profession standard treatemt of regeneration paper and dyeing waste water, ceonomizing expendeiture on capital construction 30%, reduce to the operation cost 200 thousands yuan, for villages and towns enterprise and sustained development explored new sources of revenue.
