Description
Technical field
The present invention relates to printing and dyeing washings process field, particularly to process for cleanly preparing and the complete set of equipments of a kind of washings high-quality reuse of dyeing。
Background technology
Dyeing is the industry that textile industry water consumption is bigger, and water participates in the whole dyeing and finishing course of processing as medium。The dyeing waste water water yield is big, and colourity is high, complicated component, containing dyestuff, slurry, auxiliary agent, oil preparation, soda acid in waste water, fiber impurity and inorganic salt etc., in dye structure, nitro and the heavy metal element such as amine compound and copper, chromium, zinc, arsenic have bigger bio-toxicity, serious environment pollution。
Dyeing waste-water major pollutants are dyestuff and auxiliary agent。Owing to different fibrous raw materials and product needed use different dyestuff, auxiliary agent and colouring method, add that the dye-uptake of various dyestuff is different different with the concentration of dye liquor, make dyeing waste-water change of water quality very big。The color and luster of dyeing waste-water is general relatively deep, and biodegradability is poor；Its COD is generally 300～700mg/L, BOD5/COD and is generally less than 0.2, and colourity may be up to several thousand。
Ozone is as strong oxidizer, except being applied in water sterilization, is also used widely in waste water decoloring and advanced treating。Ozone has the reason of strong oxidation, once thinks the elemental oxygen generating nascent state when decomposing, shows as strong oxidizer。It is now recognized that oxygen atom in ozone molecule inherently strong electrophilic or protophilic, directly translating into strong oxidizer is more chief reason。
Cleaning production refers to the energy constantly taking Curve guide impeller, use to clean, adopts advanced Technology and the measure such as equipment, improvement management, comprehensive utilization, pollute from source reduction, improve resource utilization, reduce or avoid generation and the discharge of pollutant in production and product use procedure, to alleviate or to eliminate the harm to human health and environment。

Further, described tubular membrane element filters tank includes a cover, described cover and the fastening of tank body secure component, and described water inlet is located at tank base, produces the mouth of a river and is located at cover top,
Described dense water out is located at tank body side。
Preferably, it is additionally provided with aerator in described tank body。
Further, described aerator is also associated with pulse gas generator。
Further, in described tank body, tubular membrane element gap is filled with implant；Described implant is circular hollow baton round or the circular short grained packing material such as wooden unit, stone。
Further, the tubular membrane element in described tank body is placed with 5-100, the corresponding branch pipe type membrane component of each aeration opening of described aerator。
Preferably, described baffled reactor is S type baffled reactor or screw type baffled reactor。
Present invention additionally comprises the process for cleanly preparing of dyeing washings high-quality reuse, it is characterised in that: adopt the complete set of equipments water inlet dyeing washings of above-mentioned dyeing washings high-quality reuse to process。
Adopt technique scheme, the process for cleanly preparing of dyeing washings high-quality reuse of the present invention and complete set of equipments, be used for washings process of dyeing, have the beneficial effect that
1) color and luster of dyeing poaching wastewater is general relatively deep, and biodegradability is poor, and intractability is big, but water consumption is high, the present invention adopts advanced oxidation, tubular membrane element filters tank, coupled ion exchange multi-stage process place desired combination, after process, water quality is good, and the water quality after process can be back to production；
2) rigidity organic filter material selected by tubular membrane element filters tank, and the performance of chemical attack is especially advantageous, resistance to various acid, alkali, salt, resistance to less than 90 DEG C overwhelming majority organic solvents；High temperature resistant；Microporous filter element mechanical strength is higher, and especially impact strength is good, light with metal and pottery weight/power ratio, is hardly damaged；
3) tubular membrane element filters tank adopts the mode of aeration in tank body, it is possible to improve the automatically cleaning ability of membrane module, alleviates the pollution of membrane module, improves the service efficiency of membrane module；Pulsed aeration, improves the efficiency of air scour, it is possible to energy efficient；
4) placing more membrane component in tubular membrane element filters tank, tank body is relatively big, when not placing implant, stores more dense water, when carrying out drain operation, it is necessary to wait the long period in tank body；After placing implant, implant occupies most of surplus space, and in tank body, the dense water yield greatly reduces, and draining is rapid, improves efficiency；The implant placed also has the coarse grained effect of filtration concurrently, to alleviate the burden of membrane component, and then extends the use time of membrane component；Through using after a period of time, available clear water or add the water of abluent implant and membrane component are carried out, all takes out membrane component and implant if desired, puts back to after cleaning, to improve treatment effeciency；
5) S type or screw type baffled reactor, band pressure mixes, and adds advanced oxidation medicament, carries out advanced oxidation, removes impurity efficiency high, and decolouring is substantially；Making the washings of entrance and pharmacy response is S-shaped or helical flow, increase incorporation time so that more homogenizing, water is better with the mixed effect of medicament, plays the effect of regulating reservoir。
