Description
Technical field
The present invention relates to a kind of processing method of closed dyeing waste water, belong to the water treatment field in environmental protection.
Background technology
It is environmental protection and energy saving (low-carbon (LC)) problems that Development of Textile Industry one of mainly hinders, and the subject matter of environmental protection is waste water, and approximately 80% textile waste comes from dyeing. Statistics demonstration, 2,300,000,000 tons of textile waste discharge capacitys in 2008, occupy the 3rd of each industrial trade, account for 10.60% of national discharged volume of industrial waste water. 31.4 ten thousand tons of COD in textile industry waste discharge (CODCr) discharge capacitys, occupy the 4th of each industrial trade, account for 7.76% of national industrial wastewater CODCr. These data are the statistics to the above enterprise of scale, and real data is much larger possibly. In fact dyeing is that medium-sized and small enterprises proportion accounts for 99.6% taking medium-sized and small enterprises as main competitive industry, and non-public enterprises account for 95%, and a large amount of small enterprises data are also not included in. If need carry out dyeing and printing process in 70% of fiber process amount, year waste discharge is about 3,000,000,000 tons of left and right.
The successful example of printing and dyeing mill's wastewater treatment is more, but not good quite a few of effect, its reason roughly has following several situation: (1) printing and dyeing mill does not analyze self waste water speciality (water quality, the water yield), indiscriminately imitates his factory's experience, and result is often undesirable. (2) by the design specification of municipal sewage treatment, for treatment of dyeing wastewater, only change some parameters, cause very large loss. Particularly in early days, large-scale printing and dyeing mill Wastewater Concentrated, be all responsible for by large-scale designing institute, and it is understood in depth not to dyeing waste water character, causes very large loss. (3) new technology, new technology, new medicament, without pilot scale, are directly used in engineering, cause a lot of failures. New technology is many should pass through lab scale, pilot scale, could be used for engineering, and generally examination scale is 3% ~ 5% of the engineering water yield, at most about magnify 20. Laboratory research achievement is directly used in engineering, and difficulty has successful case. Engineering should adopt ripe, the safest technology. (4) the close waste water of production technology, can adopt similar treatment process, but also will, according to water quality, the suitable adjustment technology parameter of the water yield, ensure processing horizontal. (5) actual motion technology and administrative skill are improper, and do not change and appropriately adjust according to waste water, be also the reason of fluctuation of service.
The progress of the rise of Silk and finishing process in printing and dye-ing technology, make the bio-refractory organic matters such as PVA slurry, artificial silk alkaline hydrolysis thing (being mainly O-phthalic acids material), New-type adjuvant enter in a large number dyeing waste water, its COD concentration also rises to 2000～3000mg/L by original hundreds of mg/L, thereby make original biological treatment system COD clearance drop to 50% left and right from 70%, even lower. Traditional biological treatment has been subject to serious challenge; Traditional chemical precipitation and By Bubble-floating Method are only also 30% left and right to the COD clearance of this class dyeing waste water. Therefore the effective techniques of Dyeing Wastewater Treatment of exploiting economy becomes the problem that current environmental protection industry (epi) is paid close attention to day by day.
