China's existing sewage disposal many employings chemical materials or mineral acid extraction technology, the method such as stimulator, sterilant is added as adopted Tai-Ace S 150, or adopt chlorinated lime to be combined with alkali, alum, but fast degradation organism and objectionable impurities can not be realized to purify improvement water quality, safeguard the water body environment eubiosis.
The water purification agent of current microorganism and nano material, its Water clarifying mechanism is as follows:
One, microbial water-purifying agent Water clarifying mechanism
1, microbial flocculation
The flocculation mechanism of current microbial flocculant mainly contains pod membrane theory, thalline outer fiber element fibril theory, charge neutrality effect, hydrophobic theory and extracellular polymeric bridge formation theory.Pod membrane theory thinks that cell defines stickiness pod membrane in process of growth, and it can cohere particle makes it to form flocs unit; Cellulose fibril theory thinks that the fibril outside thalline participates in flocculation directly, and particle is connected together, and forms flocs unit; Hydrophobic theory thinks that the adhesion of the hydrophobic interaction of particle and cell surface to bacterium is extremely important; Extracellular polymeric bridge formation theory thinks that the polymkeric substance outside bacterial body is the basic substance that flocculation produces, and these materials and Interaction between particles result in flocculation.No matter which kind of theory, the effect between microbial flocculant and particulate matter can be summed up as four kinds, i.e. charge neutrality effect, bridge linking effect, chemical bond and net are caught volume and swept effect.
(1) charge neutrality effect
Biological flocculant is generally charged biomacromolecule, can, by means of the particle generation charge neutrality effect with opposite charges in ionic linkage, hydrogen bond etc. and water, make micelle de-steady.
(2) bridge linking effect
Biological flocculant macromole simultaneously in conjunction with multiple suspended particles, can form flco by bridge formation mode by means of ionic linkage, hydrogen bond and Van der Waals force.
(3) chemical bond
Biological flocculant some active group macromolecular, as-chemical bonds can be there is with particle surface, as hydrogen bond, surface complexation etc. in OH ,-COO etc.
