Textileprintingand dyeing industrial wastewater treatment project

Generalsituationof textile printing and dyeing wastewater engineering

Theplannedarea of a new industrial park in Qingdao is 2126 mu, and the courtyardindustryis mainly weaving, dyeing and sewing. Industrial park wastewatertreatmentproject in three phases, each 5000 m after a/d, this is the firstphase ofdesign, construction, 2014, in 2015, mainly printing and dyeingwastewater ofacceptance rinse water, desizing and bleaching waste water, theprocess designincluding mercerizing process wastewater, saying a alkalirecovery.

2   处理工艺

从本工程废水特征来看，有机污染物含量较高，生化性比较差，pH值变化大，并且色度比较高。废水中含有染料、浆料、助剂、油剂、酸碱、纤维杂质、砂类物质等。

 针对于废水的特点，预处理主要有自动格栅、中和反应池、曝气调节池、初沉池等单元，预处理主要是为了去除悬浮物及可直接沉降的杂质，调整pH值，调节废水水质及水量等，确保后续生物处理系统的处理效率。为了达到较高的COD去除率，降低出水中COD的浓度，在二级生物处理中采用半推流式活性污泥系统，其抗冲击负荷能力明显强于传统推流式系统，处理效率高于传统完全混合式。针对原水色度高的特点，同时为了进一步去除COD，在深度处理中采用了混凝沉淀脱色+曝气生物滤池的两级工艺，保证了出水达标排放。

三 纺织印染废水工程设计

1    纺织印染废水工程平面设计

本项目位于生产区，占地面积11796㎡，长120m，宽98.3m，南北向布置。废水由西南侧原废水储池经泵提升进入系统，经一系列处理后的废水自流排向处理厂北侧的市政污水管道。

纺织印染废水工程高程设计

本项目高程设计时，地面标高作为处理系统的相对标高±0.00，地下构筑物标高-6.00m，地上建筑物顶标高＋6.00m，地上建筑物顶标高+6.00。除格栅井、调节池、浓缩池和清水池外，其他设施大部分采用地上式，

电气及自动控制设计

2treatmentprocess

Intermsof the characteristics of wastewater from this project, organicpollutants havehigher content, less biochemical and higher pH value, andhigher chromaticity.The waste water contains dyes, slurry, auxiliaries,oilers, acid and alkali,fiber impurities, sand substances, etc.

Accordingtothe characteristics of wastewater in, pretreatment mainly includeautomaticgrille, neutralization reaction pool, aeration regulating pond, pond,and otherunits, in the early settlement of pretreatment is to remove suspendedsolidsand can be directly impurities, adjust pH value, adjusting effluentwaterquality and water, etc., to ensure the processing efficiency of thesubsequentbiological treatment system. In order to achieve higher COD removalrate,reduce the concentration of COD in water, in the secondary biologicaltreatmentusing half pushed streaming in activated sludge system, its ability toresistimpact load obviously stronger than the traditional push streamingsystem,processing efficiency is higher than the conventional hybrid. In ordertofurther remove COD, the two-stage process of coagulationprecipitationdecolorization + aeration bio-filter is adopted in the depthtreatment, whichensures the discharge of water discharge.
