Organic pigment wastewater treatment technology to upgrade

The morning of March 17,Premier Li Keqiang and Vice Premier Zhang Gaoli, Liu Yandong,Wang Yang,Ma Kai accepted spokesman Fu Ying's invitation to convene the Twelfth National People's Congress meeting press conference,met with Chinese and foreign journalists to interview two sessions,and answer reporters' questions. Answer the People's Daily reporter mentioned:the huge China first need to solve the main problem,or sustained economic development,the key to promote economic restructuring and reform bonus potential of domestic demand,innovation vitality superimposed to form new power,quality and efficiency,employment and income, environmental protection and resource conservation and new upgrade,build an upgraded version of the Chinese economy.

In answer to the French newspaper Le Figaro reporter about Chinese economic growth can solve the problems of environmental pollution and food safety:water pollution,land pollution situation,it is necessary to find out the real determination to rectify this extensive development need to accelerate the transition.Lies to poverty and backwardness No,does not work well off affluent environment degradation.We need to further innovation and development concepts,promote scientific development.One is no longer due to the new account,including raising the threshold of environmental protection;accelerate the old debts, including the elimination of backward production capacity.Government should be an iron hand, law enforcement,the Iron Mask accountability.We can not sacrifice the environment in exchange for the people are not satisfied with the growth.Principles and the spirit of this series,can be seen,the worsening plight of East China,southeast coastal industrialized areas such as the environment,the new leader of the determination and efforts of environmental pollution control,while organic pigment production process wastewater become a major killer of the current environmental protection. The ability to break through the wastewater treatment Guan has become the key to the survival and development of organic pigment industry.

The organic pigment widely used in paints,inks and plastics industries,organic waste water,dust and exhaust gas emissions in the production process,the hazards of organic wastewater,the process is also the most difficult problems.Organic pigments produce dust pollution in the process of production,grinding,complex, organic pigment wastewater with high COD,high chroma,high salt content,refractory characteristics sewage discharged by the pigment in the production process often contains carcinogenic material (such as aromatic amines,nitrites),Kurlandsky et al pointed out that many pigments without human metabolism can be due to water-insoluble,but can be adsorbed,for example,copper phthalocyanine may be in serum protein adsorption,such adsorption accumulate in biological the body can not be eliminated.Since this adsorption accumulation can lead to the fibrin structural damage,thereby causing a change of the blood clotting ability.

Currently,conventional biological treatment the technology governance organic wastewater,although the technology has matured,but the ammonia content is still not achieve the emission standards for organic pigment industry.Governance of the newly developed abroad,such as carbon adsorption and membrane separation technology,treated wastewater can meet emission requirements,but the high cost and short life of equipment,enterprises can not afford to adopt.The current macroeconomic policies and the organic pigment wastewater treatment industry development status,radical organic pigment industry pollution problems,the key is to develop a number of advanced and mature,low-cost organic wastewater treatment technology.
