Job of energy-saving environmental protection won industry of printing and dyeing apparent success
  
Industry of printing and dyeing is in the intermediate link of catenary of textile industry industry, it is the breed of design and color of rich spin product, trade that increases spin product to additional cost is not gotten or be short of, it is the important trade that reflects competition ability of textile industry key. In the meantime, because of the characteristic of wet treatment, chemical treatment, this industry assumed whole textile industry to affect the heavy responsibility that reduces a platoon again, it is textile industry energy-saving the key trade that reduces platoon, environmental protection.
  
In recent years industry of printing and dyeing did much work in angle of the energy-saving environmental protection that decrease a platoon, threw many manpower material resources, also achieved clear result. The row if, industry of printing and dyeing undertakes large-scale technical reformation, wash out the backward facility that tall, stability needs waste time of water of specific power consumption stage by stage, water of energy-saving, section, fall the equipment increase of bad news, environmental protection, the automation of equipment controls a level to continue to promote.
  
In the meantime, industry of printing and dyeing produces processing of deepness of technology, liquid waste to follow in cleanness time use technical isogon to spend circularly with technology, resource, achieved many revolutionary progress.
  
Through these year hard, the energy-saving level that decrease a platoon had industry of printing and dyeing very big promotion, 2005~2012 year: Industry of printing and dyeing cloth of 100 meters of printing and dyeing is fresh water water consumption drops by 4 tons 2.3 tons, accumulative total decreases 42.5% ; Liquid waste of average printing and dyeing is answered with rate arrive by the 15% promotion 2005 25% above, promoted 10 percent. 2005 ~ 2011 liquid waste of printing and dyeing discharge capacity of 10 thousand yuan of production value dropped 36.79% ; Liquid waste of printing and dyeing discharge capacity of oxygen demand of chemistry of 10 thousand yuan of production value dropped 55.79% .
  
Of course, because of these year high speed develops, industry of printing and dyeing is energy-saving decrease a platoon to still leave a few bills due, existence follows place of industry progress incongruous.
   
Industry of printing and dyeing discharges a standard newly
  
" spin catchs entire industry water to affect content to discharge a standard " (GB4287-2012) since promulgating, each district is carried out actively carry out, an a few problems also are reflected in carrying out. Be aimed at the executive state of new standard, association of printing and dyeing undertook comprehensive survey, listened to liquid waste of enterprise of each district guild, printing and dyeing, printing and dyeing to treat factory opinion centrally, held “ spin to catch entire industry water to affect content to discharge a standard to carry out state seminar ” at special on November 26, 2013 organization.
  
Each district mirrors the sharpest issue to be centered in “ to discharge CODcr to be restricted to be worth ” to go up secondhand. Instantly, the enterprise CODcr accept of 95% above is in charge of a standard to be made by situation of place of basis of local government branch, or handle a company to decide centrally with sewage by enterprise of printing and dyeing, its are restricted to be worth control in 500~1000mg/L mostly. In new standard add CODcr newly to be discharged secondhand be restricted to be worth and set is 200mg/L, sensitive area is 80mg/L.
  
From this, brought main difficulty follows an issue is: Enterprise of one angle great majority must undertake to sewage disposal establishment extensive investment is transformed, ability achieves new standard to ask, and transform fulfil difficulty with land. Another angle, existing sewage handles the bear drinking water of the company to drop considerably centrally, bring about existing concentration sewage treatment plant builds content to follow equipment in great quantities unused, create austere resources waste then. For example: When sewage of Changzhou area printing and dyeing handles a factory to be built at the outset centrally, press design of the CODcr1200mg/L that drink water, CODcr100mg/L giving water commonly, too lake catchment is restricted to discharge after carrying mark to transform, give water CODcr60mg/L. If press new standard, water infection other people is special discharge be restricted to be worth (discharge CODcr80mg/L secondhand, discharge CODcr60mg/L directly) carry out, will bring about concentration to sewage treatment plant manages difficulty or cannot be managed. Be like again: Carry on promotes prefectural day to handle 1.1 million tons sewage disposal system to already was run normally, can handle liquid waste of printing and dyeing discharge standard CODcr80mg/L the following.
  
Instantly, carry on promotes a county to make an appointment with the CODcr200mg/L of enterprise short of of 50 % to discharge a standard secondhand, if want to achieve a requirement through carrying mark to transform, entire county will increase 2 billion yuan of land of 1.33 square kilometre, right-and-left investment. As we have learned, the sewage of the country such as Europe, beautiful, day discharges a standard not set is discharged secondhand be restricted to be worth. Chroma of canal of liquid waste accept is business of printing and dyeing follows the issue that discusses between water treatment enterprise, answer to develop the market to configure medium action in resource amply, adjust by market mechanism proper motion. In addition, discharge the setting that is restricted to be worth secondhand, dispersed the monitoring force of environmental protection branch, go against concentrated force quantity to do the monitoring that good fag end discharges.
  
New standard was published on October 19, 2012, carried out on January 1, 2013. Multinomial index imposes new standard severe, implementation standard upgrades need time undertakes dimensions magnifies experimenting following, will create blind investment otherwise, run a lot of corrupt practice such as waste of flabby, resources. New standard transfers without what carry mark to transform to the enterprise period.
  
In the light of discharge a standard newly, we concern sectional report to environmental protection ministry for many times, hope basis each district is actual state, relax or abolish the requirement that is restricted to be worth to be being discharged secondhand, the enterprise should be discharged finally only amount to mark, should regard as accord with standard requirement. Zhejiang province carry on promotes a county (area of current bridge stalking or branch) the government also makes a report to environmental protection ministry, the hope relaxes to discharge the requirement that is restricted to be worth secondhand.
  
The environmental protection such as morning dew environmental protection is organized about “ in article of ” of responsibility of brand of new standard test, company of involved printing and dyeing 26, main data comes from a website to publish data, detect time great majority was 2013 1~2 quarter. In 26 involved companies, discharge 1 continuously (Yageer) , accept canal discharges 25 to occupy 96.15% . Straight platoon company exceeds mark index to basically be COD, standard 100 the following, between actual 100~200. Accept is in charge of an enterprise to exceed mark to basically be content of nitrogen of oxygen demand of COD, biochemistry, ammonia, PH, chroma, in suspension to wait.
  
Be opposite in the light of everybody the opinion of new standard, classics of environmental protection ministry investigation and study, become loose somewhat, to carry on the government that promote a county returns case, roughly means falls in the state of clear and relevant responsibility, can not carry out CODcr200mg/L to discharge a standard secondhand, other area also can same method makes a report to environmental protection ministry. Instantly, carry on promotes a county to still carry out the accept of CODcr500mg/L to provide a standard.
  
Industry of printing and dyeing will advance industry environmental protection to work ceaselessly
  
The country discharges a standard to undertake raising bid in the light of liquid waste of printing and dyeing, and a few otherer environmental policy, to environmental protection of industry of printing and dyeing the work made known his position to ask newly to follow new challenge, brought difficulty to follow pressure to enterprise of printing and dyeing, but also be the underlying demand that transition of industry of printing and dyeing upgrades at the same time.
  
In recent years, enterprise of numerous printing and dyeing is in already energy-saving decreased a platoon to throw many capital to follow technical force with environmental protection angle. Industry of printing and dyeing will enlarge strength of job of the energy-saving environmental protection that decrease a platoon ceaselessly, turn job of the energy-saving environmental protection that decrease a platoon to development, do one's best achieves actual effect, make an industry energy-saving the environmental protection that decrease a platoon works more a new chance to extricateoneself from an awkward position, enhance an industry to be able to retain development ability.
