Technical field
The utility model belongs to water-jet loom processing technology field, in particular to a kind of water-saving system of water-jet loom.
Background technique
There is plurality of textile enterprise in China, and textile waste is that processing cotton, fiber crops, chemical fibre and its blending product are
The waste water of main textile mills' discharge, textile waste coloration is deep, organic pollutant content is high, change of water quality is big, constituent
It is complicated；Contain additional various slurries, dyestuff, table in dirt, grease, salt and the process on textile fabric in waste water
The pollutants such as face activating agent, auxiliary agent, soda acid, COD the and BOD content in waste water are high；The indexs such as the coloration of waste water are usually much super
Discharge standard is crossed, discharge amount is big, and concentration is high, and it is difficult to degrade, it is very big to deal with difficulty.
Waste water can be all discharged in each process of weaving, as sizing, drying and woven fabric (water-jet loom) can generate a large amount of give up
Water, the COD value for the waste water that sizing generates is up to 2000 or more, BOD value up to 400 or more, and the COD value of loom waste water is up to 400
More than, BOD value is changed greatly up to 60 or more, sanitary sewage from the COD value and BOD value of the waste water such as flushing water.
Currently, textile waste processing technique has physico-chemical process, biochemical method, electrochemical process, chemical method and photochemical method etc., wherein
Based on biochemical method, some is also connected in series by chemical method；Though various treatment process have their own characteristics each to textile printing and dyeing wastewater processing,
But there is also certain limitations.According to the water quality characteristics of textile printing and dyeing wastewater, need to solve textile waste during the treatment
The problems such as the basicity of water, not easily biological-degradable or the extremely slow organic matter of biodegradation rate；Processing method is with biological treatment
Based on method, while necessary pretreatment and physical chemistry depth logos need to be aided with.Pretreatment mainly has: adjusting (water quality and quantity
Homogenizing), neutralize, grid filtering, sedimentation etc..Common materializing strategy technique is mainly coagulant sedimentation and mixed condensed gas flotation process.This
Outside, electrolysis method, biological activated carbon method and chemical oxidization method etc. are also used for sometimes in textile waste processing.Biological treatment is main
For aerobic method, currently used active sludge, biological contact oxidation process, biological rotating disk and tower biological filter etc..To mention
The biodegradability of high waste water, anoxic, anaerobic technique have also been applied in textile waste processing.The processing of existing textile printing and dyeing wastewater
Technology will usually reach national secondary discharge standard (COD40-120, BOD20-40) and discharge afterwards after waste water simple process, then benefit
With more difficult, it usually only can be used as rinse water.
Such as application No. is a kind of processing method of wastewater in textile printing and dyeing industry of the patent disclosure of CN200910136664 .X,
The method includes the steps as follows: A pre-processes high chroma dyeing stoste: by high chroma dyeing stoste injection color reaction
Then pond adds flocculant FeCl3, dosage is that 200-400mg/L high chroma dyes stoste, residence time 5-7h；B homogeneous
Change processing: the product of step A, other waste water and waste liquids and the outer organic wastewater that draws are put into conditioning tank, residence time 7-9h；C is raw
Change processing: the water outlet of conditioning tank sequentially enters hydrolysis acidification pool, aerobic tank and sedimentation basin, and sewage is in this stage residence time
45-50h；Flocculation treatment after D: flocculant FeSO is added into the water outlet of step C4Flocculation treatment after progress；After processing, it is discharged
Water quality meets the I grade standard of GB4287-92 " textile dyeing and finishing industrial water pollution object discharge standard " table 3.
Such as application No. is the patents of CN200510092957 .8 to disclose the work of a kind of processing of textile printing and dyeing wastewater and reuse
Skill includes the following steps: pre-treatment, and conditioning tank enters level-one flotation tank by elevator pump in textile waste, by adjusting air bearing
The reflux ratio in pond and dissolved-air pressure further remove the impurity such as lint in waste water, and increase the dissolved oxygen content in waste water；
Biochemical treatment is carried out later, using domestication, after carrier type thermopnore composite membrane mud reactor after biofilm is to level-one air-flotation process
Waste water carry out the aerobic decomposition of organic matter, by stirring, aeration so that the dissolved oxygen in waste water is maintained at proper level, this process
In so that the organic matter in waste water is obtained most degradation, subsequently into activated sludge tank, further organic matter is carried out
Waste water, is most introduced sedimentation basin after biological decomposition afterwards by oxygen solution, and the active sludge biological that wastewater sedimentation is got off flows back into CBR
In reaction tank, sedimentation basin water outlet reaches discharge standard；Post-processing, second pond supernatant are discharged to secondary air-floatation pond, pass through adjusting
The reflux ratio and dissolved-air pressure of flotation tank further remove useless impurities in water and suspended particulate substance and colloid, guarantee wastewater effluent
Water quality indicator, then waste water is introduced in ozone oxidation pond again, will be difficult in biological treatment process by the strong oxidizing property of ozone
It is further degraded with the organic matter of explanation, and using the decoloration performance of ozone, guarantees the coloration of water outlet.The patent can handle
Pollution concentration is high, and coloration is high, the unstable textile printing and dyeing wastewater of water quality.
