[35], whiterot fungi
[36])
Advantage: with low cost.
Shortcoming: hydraulic detention time is longer, remove the colourity ability a little less than, anti-organic loading and inorganic salt impact capacity are relatively poor.
In sum, every kind of water treatment method has the defective of self, such as cost, and feasibility, practicality, reliability, stability, environmental influence, the mud output, poor operability needs pre-treatment, the toxicity of organic removal rate and potential product etc.
In recent years, carried out the research of magnesium salts method treatment of dyeing and printing both at home and abroad, its bleaching principle is that the magnesium salts alkaline hydrolysis generates positively charged magnesium hydrate precipitate, the anionic dyestuff that its strong adsorption is electronegative and make decoloring dye waste water with anionic charge.Xu Kun [Xu Kun, Jia Zhiping, Jiang Zhaochun. magnesium hydroxide is to the research of anionic dyestuffs waste water decoloring. environmental chemistry .1998,17 (1): 94-99.], Ji Ming [Ji Ming, Zhao Yijiang, Zhang Yan, Deng. magnesium hydroxide is processed decolorizing printing and dyeing waste water. water technology, 2000,26 (4): 245-248.] etc. people's research is found, should not surpass 1.5min storage period behind the magnesium hydrate precipitate absorbing dye, affects decolorizing effect otherwise desorb can occur, carry out solid-liquid separation in the so short time and be difficult in actual applications realize to also have magnesium hydroxide settling of floccus effect also relatively poor.In addition, most of documents all are the application for water-soluble dye, and the magnesium salts method for dispersed dye, vat dyes, etc. the removal effect of water-insoluble dyestuff relatively poor.
Molysite/aluminium salt/calcium salt/conventional flocculation agents such as organic polymer are better for the removal effect of water-insoluble dyestuff, and relatively poor for the removal effect of water-soluble dye.
