Description
Technical field
The present invention and a kind of water technology particularly disclose a kind of process for treating water specialized for textile dyeing, are applied to dope dyeing Treatment of Industrial Water field.
Background technology
Textile printing and dyeing industry is one of basis composition department of industry, also is one of traditional mainstay industry of China.Dyeing and finishing industry is the bigger industry of water consumption in the textile industry, water is an obligato resource, the courses of processing such as the pre-treatment of all kinds of textile products, dyeing, stamp all must could realize as media with water, and dyeing and finishing processing quality of water is that certain requirement is arranged.
So far, still do not have relevant country or industry standard and standard for dyeing and finishing water water quality and can be used as foundation, have only Shanghai printing and dyeing industry employer's organization establishment " in the printing and dyeing handbook " dyeing water water-quality guideline " as a reference, general requirement turbidity≤10NTU, hardness are that 9～18mg/L, iron≤0.1mg/L, manganese≤0.1mg/L, pH are 7～8.
Yet adjustment along with textile industry development of technology and structure paces, a collection of high-grade textile industry emerges and enlarges rapidly, its product (as textile cheese, combed yarn etc.) is no matter bleaching or dyeing, more and more higher to requirements in water quality, as turbidity, colourity (≤3), pH, hardness (≤1.5mg/L), metal ion (iron, manganese, copper), basicity, chlorine residue, organism etc. all have stricter control requirement, common water technology can't satisfy this demand.
General dope dyeing comprises with the automatic control content of water technology: the automatic cleaning of the automatic start-stop of equipment, equipment or the automatic switchover of regeneration and equipment.
Because the raising constantly of water quality requirement and the development of Technology; control requirement is also high more thereupon automatically for it; not only to finish general automatic control; also should comprise more perfect, more accurate, more advanced automatization control; for example Automatic Dosing, statistic data, monitoring automatically automatically, report to the police automatically, protection automatically, automatic constant-pressure supply water, it is far from being enough only depending on general autocontrol method.
In the daily operation management process, because general full-time staff carries out continuous footman's operation, personnel dispose more, and the ability to accept difference of personnel after training, occur mishandle easily, in time water inlet and effluent quality are not monitored etc., do not meet the requirement of safe operation management, have influence on security of system to a great extent and move reliably, cause damage.
Price rises steadily along with global energy is in short supply in recent years, and energy-conservation is the problem that present enterprise presses for solution.Yet power and water also is a requisite resource in the water treatment system, and water saving and economize on electricity are the energy-conservation important indicator of water treatment system, and be significant.
Summary of the invention
The objective of the invention is to solve the problems referred to above that the dope dyeing water processing system exists at present, improved the quality of dope dyeing water.The present utility model people emphasis research and development aspect process for treating water specialized for textile dyeing in recent years make water technology produce breakthrough variation.Simultaneously, by optimizing Process configuration and modularity design technology, make the system's of producing hommization more, environmentization, modernization, open process for treating water specialized for textile dyeing, it is the sign of modernization process level, be save construction investment, cut down the consumption of energy, reliable assurance.
The present invention is achieved in that process for treating water specialized for textile dyeing, the pre-treatment that comprises water is filtered, the softening processing, it is characterized in that: adopt modular design from intaking to the water outlet whole process, whole process flow is filtered module, softening module, adsorption module, advanced treatment module by pre-treatment and is contacted successively and form; The collective and distributive type automatic control system is adopted in the work of modules at different levels in the flow process, by the PC technology, realizes each technical process module working condition centralized management of system, decentralised control.Described pre-processing module is formed filtration module by ultrafiltration or aeration and conventional filter etc., after pre-treatment, reaches turbidity≤0.3NTU, total iron≤0.1mg/L, manganese≤0.02mg/L.Described softening module is meant that the sodium ion in calcium, magnesium ion and the cationite of forming the water hardness composition exchanges, calcium in the water, magnesium ion are replaced by sodium ion, thereby remove the composition-calcium, the magnesium ion that cause water hardness, obtain the effect of water demineralization.Go out total hardness of water≤1.5mg/L.Described adsorption module mainly is colourity, organism and the free chlorine in the planar water, also can be used for decolouring.Its water outlet chlorine residue≤0.05mg/L, colourity≤3 degree, COD≤20mg/L.Described advanced treatment module mainly is to guarantee that the pH of product water is 6.5～8.5, nitrate≤50mg/L, nitrite≤5mg/L, muriate≤250mg/L basicity≤150mg/L.Water pump in the system is carried out speed control by frequency variation, realize the electricity-saving function of motor.
The invention has the beneficial effects as follows: the present invention adopts the whole process modular design, and the equipment design in the process for treating water specialized for textile dyeing is become integrated device, has improved the quality of dope dyeing water simultaneously.The whole process modular design can be added arbitrarily or delete and do not influenced the operation of total system, realizes water quality objective, therefore has very high handiness in application facet, loads and transports easyly, and transportation cost is low; Modular design not only makes construction quality improve, and construction period shortens; But also improved quality product; Compact construction between the unit, floor space is little.
