化纤毛绒织物碱减量烂花废水生化处理

碱减量烂花技术会产生高CODCr、难降解的印染废水。普通印染废水处理系统可以接受的碱减量废水量有限,碱减量废水量多或浓度高都会导致原有普通印染废水处理系统出水不达标。因此,碱减量废水处理已成为限制其生产扩产的瓶颈问题。采用物化、微电解+生化联合处理工艺,首先对碱减量烂花废水进行酸析气浮预处理,去除部分对苯二甲酸钠,再经过微通量流化床反应器进行生化处理。

Biochemical treatment of alkali reduction burnt-out wastewater from chemical fiber plush fabrics

Alkali reduction burn-out technology produced high CODCr,refractory printing and dyeing wastewater.The amount of alkali reduction wastewater that could be accepted by ordinary printing and dyeing wastewater treatment system was limited.Too much or high concentration of alkali reduction wastewater caused the effluent of the original ordinary printing and dyeing treatment system to fail to meet the standard.Therefore,the treatment of alkali reduction wastewater had become a bottleneck problem that limited the expansion of production process.The treatment process was a combination of physical and chemical,micro-electrolysis and biochemical.The acid precipitation treatment of the alkali reduction burn-up wastewater was performed to remove a part of sodium terephthalate.Then the wastewater was biochemically treated in the microfluidized fluidization reactor.
