Abstract
The invention relates to an integrated dyeing wastewater treatment device and a treatment method thereof. The device comprises a wastewater treatment module, a sludge treatment module and a methane recycling module. The treatment method comprises the following steps: degrading pretreatment wastewater with anaerobic bacteria in a spirally symmetrical flow anaerobic reactor, and performing oxidation-reduction reaction on dyeing wastewater with anaerobic microorganisms in an efficient decoloring anaerobic reactor so as to promote dye reduction; performing nitrification-denitrification denitrogenation treatment on the obtained wastewater in an airlift external-circulation vortex enhanced biological denitrification reactor, mixing obtained biochemical sludge with sludge from physical-chemical treatment, then performing dehydration, and performing hydrothermal reaction in a hydrothermal reactor so as to realize pyrohydrolysis of degradation-resistant particles to obtain easily degradable organic matters; finally degrading and digesting the easily degradable organic matters in an efficient anaerobic digester so as to convert the easily degradable organic matters into methane. According to the treatment method, anaerobic biological treatment is performed on the pretreatment wastewater and the dyeing wastewater respectively, so that the pertinence is improved, printing and dyeing sludges are decreased and recycled, and system heat losses are reduced.
Description
Technical field
The invention belongs to the technical field for the treatment of of dyeing wastewater, particularly relate to a kind of integrated printing and dyeing wastewater processing equipment and place thereof
Reason method.
Background technology
Textile industry is the conventional column industry of Chinese national economy, be also important people's livelihood industry and international competitive advantage brighter
Aobvious important industry.A large amount of waste water can be produced during caused by spinning industrial production, have that organic concentration is high, colourity big, can
The features such as biological degradability difference, are the Typical Representatives of high concentration hard-degraded organic waste water, if not dealt carefully with it, easily
Environment is caused serious harm.But, current printing-dyeing waste water treatment process there is also problems, predominantly Process for Effluent water
Matter be difficult to up to standard, sludge yield is big and thermal loss is big etc..
Effluent quality is difficult to up to standard: dyeing waste water by its from production stage can be divided into pre-treatment waste water and dyeing is useless
Water, both of which is high temperature (> 70 DEG C), high chemical oxygen demand (COD, > 2000mg/L) waste water.The COD of pre-treatment waste water
Mainly contributed by slurry (such as polyvinyl alcohol (PVA), carboxymethyl cellulose (CMC), starch etc.), and the COD of dyeing waste-water
Mainly contributed by dyestuff.Owing to two kinds of waste water mixing post-processing difficulty strengthen, and current anaerobic biological reactor treatment efficiency and
Specific aim is not enough, causes waste water subsequent technique to process and is difficult to reach discharge standard.
Sludge yield is big: generation printing and dyeing sludge is comprehended at the place of dyeing waste water, printing and dyeing sludge because of containing many poisonous and harmful substances,
Being classified as danger wastes, its processing cost is higher.But also contain many organic principles in printing and dyeing sludge, there is anaerobism and disappear
Change methanogenic potentiality.We show early-stage Study: although printing and dyeing sludge is due to complicated component, the hydrolysis in its anaerobic digestion
Step is restricted, it is impossible to be anaerobically digested, but after pretreatment, can be used successfully to anaerobic digestion methane phase,
And in acid, alkali, thermokalite, high temperature preprocess method, the effect of high temperature pretreatment is best, up to 51.8ml/gVSS in 10d,
And there occurs significant mud decrement.Visible, as long as using suitable method that printing and dyeing sludge is carried out pretreatment, then detest
Oxygen digestion just can reach the purpose of resource reusing and sludge reduction.
Thermal loss is big: dyeing waste water temperature higher (> 70 DEG C), if directly using biological treatment can poison microorganism.At present
Often using cooling tower to lower the temperature in engineering, the temperature of dyeing waste water is directly walked heat by water cyclic steam volatile zone, causes heat
The serious waste of amount, therefore, it can consider the heat of system is used.
Summary of the invention
