Detailed description of the invention
The main component that the present invention cultivates micro-algae culture medium is:
Sodium nitrate, dipotassium hydrogen phosphate, magnesium sulfate, calcium chloride, sodium carbonate, citric acid, ironic citrate and trace element etc.
The algae kind of micro-algae:
The algae kind of micro-algae be screen after the micro-algae of resistant tamed again, this algae kind can be survived in the water polluted, and can purify water.
Mechanism based on invention research is as follows:
The mechanism of the pollutants such as micro-algae treatment of nitric acid salt, sulfate, ammonium salt, sodium salt:
Micro-algae needs a large amount of nutrients in the process of growth, and sufficient nutriment can promote the growth of micro-algae, and the growing state of micro-algae is better, and the treatment effeciency of nutriment also can be higher.Micro-algae utilizes carbon dioxide and carbonate as carbon source, organic nitrogen in waste water and inorganic nitrogen are as nitrogenous source, under the effect of luminous energy, carry out photosynthesis, the ammonia salt in absorption waste water, nitrate, Nitrite transformation become microalgae cell inside to be rich in the amino acid and protein of nutrition.If oxygen is more sufficient, the phosphorus in waste water directly can be absorbed by micro-algae, changes into the organic matter such as phosphatide, ATP be stored in cell by the method for multiple phosphorylation; If oxygen is more rare, or do not have oxygen, micro-algae can be precipitated the phosphorus in waste water in the form of phosphate.Nutriment can at microalgae cell building up inside, and the oil productivity of micro-algae also can improve a lot.
The mechanism of micro-algae process heavy metal ion:
The heavy metal ion that micro-algae is removed in waste water can realize by adsorbing and accumulating these two steps.Micro-algae Adsorption of Heavy Metal Ions can be divided into biosorption process and physisorphtion two kinds, mainly based on biosorption process.The principle of absorption is that the surface of micro-algae is mainly electronegative polysaccharide, and the easy and micro-algae of the positively charged heavy metal ion in waste water attracts each other.Accumulation is a kind of active transport processes of micro-algae process heavy metal ions in wastewater, in whole process, needs micro-algae to provide energy by metabolism.Absorb in the process of heavy metal ion in whole micro-algae, the amount of accumulation heavy metal only accounts for 10% ~ 20% of gross absorption, and the amount of biological adsorption then accounts for 80% ~ 90%, and therefore biological adsorption is the main path absorbing heavy metal ion.
The effect of the microalgae cell Adsorption of Heavy Metal Ions of dead microalgae cell phase specific activity is better.This is because it is certain that the cell surface of micro-algae amasss, and cell membrane has selective penetrated property, generally only have the ion of part neutrality permeate through cell membranes can enter cell interior, and most ion is all blocked in outside cell; When after micro-algae death, membranolysis, the more functional group of cell interior leaks outside, and heavy metal ion is easier to be combined with them; Without the stop of cell membrane, heavy metal ion also more easily enters cell interior thoroughly, and therefore total adsorption capacity strengthens.
The organic mechanism of micro-algae process:
Dirty Organic substance in water can be the carbon source that algal grown provides important.Algae to organic removal mainly by enrichment and degraded.The purification of micro-algae to organic pollution comprises attachment, absorption, accumulation and degraded etc.The body surface absorption large amount of organic of micro-algae, reduces the concentration of Organic substance in water relatively.
Algae liquid in storage algae pond comprises the algae kind, culture medium, water etc. of micro-algae.
