工業(yè)廢水，是工業(yè)污染引起水體污染的最重要的原因。它占工業(yè)排出的污染物的大部分。工業(yè)廢水所含的污染物因工廠種類不同而千差萬別，即使是同類工廠，生產(chǎn)過程不同，其所含污染物的質(zhì)和量也不一樣。工業(yè)除了排出的廢水直接注入水體引起污染外，固體廢物和廢氣也會污染水體。

紡織印染行業(yè)是工業(yè)污水排放大戶，污水中主要含有紡織纖維上的污物、油脂、鹽類以及加工過程中附加的各種漿料、染料、表面活性劑、助劑、酸堿等。

    廢水特點是有機物濃度高、成分復(fù)雜、色度深且多變，pH變化大，水量水質(zhì)變化大，屬難處理工業(yè)廢水。隨著化學(xué)纖織物的發(fā)展，仿真絲的興起和印染后整理要求的提高，使PVA漿料、人造絲堿解物、新型染料、助劑等難降解有機物大量進(jìn)入紡織印染廢水，對傳統(tǒng)的廢水處理工藝構(gòu)成嚴(yán)重挑戰(zhàn)，COD濃度也從原來的數(shù)百毫克每升上升到3000～5000mg/l。

    漿染廢水色度高、COD高，特別是近年根據(jù)國外市場開發(fā)出來的絲光藍(lán)、絲光黑、特深藍(lán)、特深黑等印染工藝，該類印染大量使用硫化染料、印染助劑硫化鈉等，因此廢水中含有大量的硫化物，該類廢水必須加藥預(yù)處理，然后再進(jìn)行系列化處理，才能穩(wěn)定達(dá)標(biāo)排放。漂染廢水中含有染料、漿料、表面活性劑等助劑，該類廢水水量大，濃度和色度均較低，如果單純采用物化處理，則出水也在100～200mg/l之間，色度也能以滿足排放要求，但污染量大大增加，污泥處理的費用較高，容易造成二次污染，在目前環(huán)保要求較嚴(yán)的情況下應(yīng)充分考慮生化處理系統(tǒng)，常規(guī)的強化生物處理工藝可以滿足處理要求。

Industrial waste water is the most important cause of water pollution caused by industrial pollution. It accounts for most of the pollutants discharged from industry. Industrial wastewater contains varied pollutants due to different plant types. Even in similar factories, the quality and quantity of pollutants contained are different from those of similar factories. In addition to the direct injection of waste water from the wastewater to cause pollution, solid waste and waste gas will also pollute the water body.

Textile printing and dyeing industry is a large number of industrial sewage discharge. Sewage mainly contains dirt, grease and salts on textile fibers, and various kinds of slurry, dyes, surfactants, auxiliaries, acid-base and so on.

The characteristics of wastewater are the high concentration of organic matter, complex composition, deep and changeable color, large change of pH and great change in water quality and water quality, which is a difficult to treat industrial wastewater. With the development of chemical fiber fabrics, silk printing and dyeing rise and finishing requirements increase, the PVA slurry, rayon, alkali hydrolysis new dyes and additives of biodegradable organic matter in textile printing and dyeing wastewater, wastewater treatment process of a serious challenge, the concentration of COD from hundreds of milligrams of the original per liter rose to 3000 ~ 5000mg/l.

Dyeing wastewater has high chroma, high COD, especially in recent years, according to the foreign market development out of the blue, black, mercerized mercerized blue, black and other printing and dyeing process, the extensive use of sulfur dyes, dyeing auxiliaries such as sodium sulfide, therefore contain large amounts of sulfide in wastewater, the wastewater must be pretreated before dosing. A series of processing, in order to discharge. Dye, size and surface active agents containing bleaching and dyeing wastewater, the wastewater quantity, concentration and chroma are relatively low, if only by physical and chemical treatment, the effluent is between 100 ~ 200mg/l and chroma can to meet the emission requirements, but the amount of pollution is greatly increased, and the sludge disposal costs are high, easy to cause two pollution, in the current environmental protection requirements more stringent conditions should be fully considered in the biochemical treatment system, the conventional enhanced biological treatment process can meet the processing requirements.
