Textileprinting and dyeing industrial wastewater treatment project
Generalsituation of textile printing and dyeing wastewater engineering
Theplanned area of a new industrial park in Qingdao is 2126 mu, and the courtyardindustry is mainly weaving, dyeing and sewing. Industrial park wastewatertreatment project in three phases, each 5000 m after a/d, this is the firstphase of design, construction, 2014, in 2015, mainly printing and dyeingwastewater of acceptance rinse water, desizing and bleaching waste water, theprocess design including 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。

2treatment process
Interms of the characteristics of wastewater from this project, organicpollutants have higher 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.
Accordingto the characteristics of wastewater in, pretreatment mainly include automaticgrille, neutralization reaction pool, aeration regulating pond, pond, and otherunits, in the early settlement of pretreatment is to remove suspended solidsand can be directly impurities, adjust pH value, adjusting effluent waterquality and water, etc., to ensure the processing efficiency of the subsequentbiological treatment system. In order to achieve higher COD removal rate,reduce the concentration of COD in water, in the secondary biological treatmentusing half pushed streaming in activated sludge system, its ability to resistimpact load obviously stronger than the traditional push streaming system,processing efficiency is higher than the conventional hybrid. In order tofurther remove COD, the two-stage process of coagulation precipitationdecolorization + aeration bio-filter is adopted in the depth treatment, whichensures the discharge of water discharge.
Threetextile printing and dyeing wastewater engineering design
Textileprinting and dyeing wastewater engineering graphic design
Thisproject is located in the production area, covers an area of 11796 ㎡, with 120 m long, 98.3 m wide, north and south to decorate. Thewaste water is pumped into the system by pump through a series of treatedwastewater from the waste water storage pool in the southwest side, and thenthe municipal sewage pipe is placed in the north side of the treatment plant.
Textileprinting and dyeing wastewater engineering elevation design
Duringthe elevation design of this project, the ground level elevation as therelative elevation of the processing system is plus or minus 0.00, theelevation of the underground structure is high -6.00 m, the elevation of theabove-ground buildings is high +6.00 m, and the roof elevation of theabove-ground buildings is high + 6.00. In addition to grille Wells, regulatingponds, concentrated pools and water basins, most of the other facilities are onthe ground,
Electricaland automatic control design
