Textile printing and dyeing industrial wastewater treatment project

General situation of textile printing and dyeing wastewater engineering

The planned area of a new industrial park in Qingdao is 2126 mu, and the courtyard industry is mainly weaving, dyeing and sewing. Industrial park wastewater treatment project in three phases, each 5000 m after a/d, this is the first phase of design, construction, 2014, in 2015, mainly printing and dyeing wastewater of acceptance rinse water, desizing and bleaching waste water, the process design including mercerizing process wastewater, saying a alkali recovery.

2   處理工藝 

從本工程廢水特征來看，有機(jī)污染物含量較高，生化性比較差，pH值變化大，并且色度比較高。廢水中含有染料、漿料、助劑、油劑、酸堿、纖維雜質(zhì)、砂類物質(zhì)等。

  針對于廢水的特點(diǎn)，預(yù)處理主要有自動格柵、中和反應(yīng)池、曝氣調(diào)節(jié)池、初沉池等單元，預(yù)處理主要是為了去除懸浮物及可直接沉降的雜質(zhì)，調(diào)整pH值，調(diào)節(jié)廢水水質(zhì)及水量等，確保后續(xù)生物處理系統(tǒng)的處理效率。為了達(dá)到較高的COD去除率，降低出水中COD的濃度，在二級生物處理中采用半推流式活性污泥系統(tǒng)，其抗沖擊負(fù)荷能力明顯強(qiáng)于傳統(tǒng)推流式系統(tǒng)，處理效率高于傳統(tǒng)完全混合式。針對原水色度高的特點(diǎn)，同時為了進(jìn)一步去除COD，在深度處理中采用了混凝沉淀脫色+曝氣生物濾池的兩級工藝，保證了出水達(dá)標(biāo)排放。

2 treatment process

In terms of the characteristics of wastewater from this project, organic pollutants have higher content, less biochemical and higher pH value, and higher chromaticity. The waste water contains dyes, slurry, auxiliaries, oilers, acid and alkali, fiber impurities, sand substances, etc.

According to the characteristics of wastewater in, pretreatment mainly include automatic grille, neutralization reaction pool, aeration regulating pond, pond, and other units, in the early settlement of pretreatment is to remove suspended solids and can be directly impurities, adjust pH value, adjusting effluent water quality and water, etc., to ensure the processing efficiency of the subsequent biological treatment system. In order to achieve higher COD removal rate, reduce the concentration of COD in water, in the secondary biological treatment using half pushed streaming in activated sludge system, its ability to resist impact load obviously stronger than the traditional push streaming system, processing efficiency is higher than the conventional hybrid. In order to further remove COD, the two-stage process of coagulation precipitation decolorization + aeration bio-filter is adopted in the depth treatment, which ensures the discharge of water discharge.
