Inorganic salts plays the promotion enzyme reaction in microorganism growth process, the vital role of keeping membrane equilibrium and regulating osmotic pressure.But salt concn is too high, can produce restraining effect to microbial growth, mainly suppresses reason and is:
(1), when salt concn is too high, osmotic pressure is high, makes the microorganism cells dehydration cause that cellular plasm separates.
(2), because making dehydrogenase activity, reduces salting out in high saliferous situation.
(3), high Cl~-concentration is to the toxic effect of bacterium.
(4), because the density of water increases, the active sludge loss of easily floating.
For this reason, the biological treatment of high slat-containing wastewater need to be diluted, and under low salt concn (salt concn is less than 1% operation), cause the waste of water resources usually, and treatment facility is huge, increase of investment, and working cost improves.Along with the day of water resources is becoming tight, the every rules of water conservation that country puts into effect and the enforcement of charge, the enterprise that processes to high slat-containing wastewater has brought burden.
Also someone studies biological method and processes high slat-containing wastewater, but during from fresh water environment to hypersaline environment, may cause the change of microbial metabolism approach due to the variation of salt, the result that bacterial classification is selected makes the bacterial classification that adapts to high salt less, only have when microorganism after cultivating domestication, could produce the bacterial classification that adapts to high salt, to tolerate certain salt concn.And the method effect of biological treatment and not obvious, and processing cost is higher, and also higher to the requirement of equipment.
The chemical substance treatment technology of high salinity waste water relatively is short of at present, have and use electrochemistry to process, but impracticable, the energy consumption of electrochemical process is high, equipment easily corrodes, working cost is high, so the practical large-scale industrial application is also fewer, and also also more difficult to the waste gas of the conductivity of equipment and generation.
