Description
Technical field
The present invention relates to the Industrial Wastewater Treatment of difficult for biological degradation, the method handled of textile printing and dyeing wastewater is particularly especially utilized the method for anerobic-anoxia-aerobic-coagulated precipitation comprehensive treating process waste water.
Background technology
Textile printing and dyeing wastewater component complexity often contains multiple dyestuff, and colourity is dark, strong toxicity, and difficult degradation, the pH fluctuation is big, and the concentration height, and wastewater flow rate is big, is one of unmanageable trade effluent.The method that microbial biochemical is handled is to generally acknowledge efficient height, effective method, but also there are some defectives in the processing that simply is used for textile printing and dyeing wastewater.Use biochemical method preferably to be during textile printing and dyeing wastewater is handled at present: the biological treatment that adopts " acidication-aerobic ".Microorganism in the biological treatment of " acidication-aerobic " has certain requirement to conditions such as nutritive substance, pH value, temperature, is difficult to adapt to the characteristics that the textile printing and dyeing wastewater variation water quality is big, the dyestuff kind is many, toxicity is high; Have also simultaneously that floor space is big, complex management, to shortcomings such as colourity and COD clearance are low.
In recent years, development along with dyestuff and Auxiliaries Industry thereof, the usage quantity of macromole, multifunctional dye constantly increases, the raising that improvement of textile printing and dyeing process simultaneously and industry water saving require, the Pollutant levels of textile printing and dyeing wastewater improve constantly, the biodegradability variation of waste water, so the textile printing and dyeing wastewater treatment technology has been proposed renewal, higher requirement, conventional treatment process is difficult to satisfy the requirement up to standard of waste water.In addition domestic weaving textile printing and dyeing industry has sizable scale, and the amount of textile printing and dyeing wastewater is also very big.
At the textile printing and dyeing wastewater of high density, difficult degradation, carried out a large amount of researches of technique both at home and abroad, wherein anaerobic biological treatment is the emphasis of various countries' research.Some is difficult to resolve compound (as aromatics) and under anaerobic can be effectively decomposed, as bioremediation referring to the CN200310112207.X textile printing and dyeing wastewater, adopt anaerobic baffled reactor (ABR) to criticize the treatment process that sequencing batch reactor activated sludge reaction device (SBR) combines with preface, in decolouring, follow the aniline that decolours and produce to obtain the part degraded.High and contain the waste water of hard-degraded substance to organic content, anaerobic biological treatment has unique advantages.In addition, the exploitation of new and effective anaerobic reactor makes anaerobic processing device usefulness that large increase arranged, and the requirement of water inlet COD concentration reduces greatly.The industrial high efficiency anaerobic reactor of being presided over technically by the applicant just has some in stable operation.All above-mentioned theory utilize the progress of anaerobic reactor processing high density textile printing and dyeing and waste water from dyestuff that assurance is provided with being practiced as.
Along with people improve constantly environmental quality requirement and improve, wastewater discharge standard requires also more and more stricter.How to obtain to stablize, the textile printing and dyeing wastewater treatment effect is very important efficiently.At present, no matter the materialization treatment technology still is anaerobism, aerobic and integrated technology, and people are confined to its optimum process condition research is separately carried out, and do not consider the component of anaerobic treatment generation and the influence that structure is handled follow-up aerobic biochemical.
