Description

A kind for the treatment of process of dyeing and printing sewage
Technical field
The present invention relates to dyeing and printing sewage processing technology field, be specifically related to a kind for the treatment of process of dyeing and printing sewage.
Background technology
Water treatment is the eternal problems of the mankind.Along with China's Economic development, national water consumption rises year by year, and wastewater emission amount increases, and the wastewater emission amount increased year by year causes water treatment pressure to increase.Textile industry is the traditional mainstay industry of China, " three wastes " that discharge in dyeing production process, especially waste water, improperly will cause severe contamination to environment if administered.According to incompletely statistics, China's dyeing waste water quantity discharged every day is 400 ~ 600 ten thousand steres.Dyeing waste water has the features such as the water yield is large, organic contamination substrate concentration is high, colourity is dark, alkalescence is high, change of water quality large, complicated component, belongs to one of more unmanageable trade effluent.
Traditional sewage water treatment method such as sterilization, purification, the process of desalination contour strength chemical can solve a lot of pollution problem.But, these methods all need to consume a large amount of manpowers and energy usually, and can only by needing a large amount of funds, the larger processing system of engineering and Infrastructure support and realizing, therefore a lot of place all cannot make to carry out sewage disposal in this way, hampers its promotion and application worldwide.In addition, the chemical treatment of high strength (such as relates to ammonia, muriate, hydrochloric acid, sodium hydroxide, ozone, potassium permanganate, alum and molysite, condensing agent and helps and consider the corrosion control such as agent, Scale inhibitors chemical agent, and the chemical treatment such as ion exchange resin and regenerator) and residue (mud, bittern, Toxic waste etc.) all can become a source of fresh water pollution and salinization.
In recent years, iron/water micro electrolysis tech is used to sewage disposal, the method almost can be used in processing all can not the waste water of biochemical treatment, killing action can also be played to water-borne pathogens simultaneously, and ferro element reserves in the earth's crust are huge, cheap, this method is without the need to additional equipment in addition, without the need to strong oxidizer, be therefore considered to a kind of eco-friendly treatment process.At present, iron powder and cast iron scrap have been widely used in the process of dyeing waste water.
But in the process of reduced iron powder treatment of dyeing and printing, there are the following problems: (one) iron powder business and standard brick often; Compared with reduced iron powder, the index such as purity, activity of cast iron scrap is poor, causes needs just can reach the standard of subsequent disposal compared with the long process time; (2) pH value of this method to dyeing waste water there are certain requirements, and this just needs to carry out pH value adjustment to large batch of dyeing waste water, causes practical application inconvenient; (3) there is the serious problem that hardens in iron/water light electrolysis; Although utilize nanometer iron powder to a certain degree preventing from hardening, be both and have larger specific surface area, the manufacture difficulty of nanometer iron powder is very high, is difficult to realize suitability for industrialized production, with high costs; (4) because reduced iron powder and cast iron filing, in the treatment of dyeing wastewater process of reality, serious oxidation can occur, cause the corrosion consumption of iron, and due to iron very easily with acid-respons, the poor operability of the recovery of its surface reduction ability is realized by pickling, difficulty is brought to the recycling of reduced iron powder or cast iron scrap, often only can carry out a wastewater treatment, the cost causing the method raises, and limits its widespread use.
In order to make up utilize reduced iron powder or cast iron scrap dyeing waste water processed existing for treatment condition more, treatment effect is not good, and can reusing difference etc. shortcoming, scientific research personnel obtains Fe base amorphous ribbon by amorphization techniques, has carried out the research utilizing Fe base amorphous ribbon treatment of dyeing and printing.In Fe base noncrystal alloy, iron exists with atomic state, remain that Zero-valent Iron itself has except look function, and having advantage that is Fe-based amorphous and strip sample concurrently, is a kind of printing and dyeing water decoloring material well.But the efficiency of Fe base amorphous ribbon process dyeing and printing sewage is still lower, can't meet the actual demand of dyeing and printing sewage process.
