Technical field
It is especially a kind of to carry out wastewater using Hydrodynamic cavitation the present invention relates to a kind of wastewater system
Device.
Background technique
Brewing wastewater is mainly derived from the cleaning of wine-making technology and fermentation liquid distills two processes, and every 1 ton of alcohol of production will
Waste liquid 13-16 tons of discharge, and its organic concentration is high, suspended particulate is more, BOD/COD ratio is big, is that brewing industry is difficult to deal with
A kind of waste water, color are in black, and solid content is high, seriously pollute water environment, and are discharged into river and will cause the tight of water body
Heavyeutrophication, phenomena such as leading to red tide.
Brewing wastewater often has microbial method, electrolysis method, flocculence and catalysis method with processing method at present.Microbial method lacks
Point is not easy to survive, and microbial method is to microorganism fungus kind to be difficult to find suitable degrading bacteria having found strain
Debug time it is too long, to experiment condition require it is harsher.Although it is obvious that electrolysis method handles brewing wastewater effect, some
Battery can weaken experiment effect using oxidizable material as electrode, and some electrolytic processes environment can be caused it is certain

The time used in waste water is handled less, but catalyst used in this method has that the cost is relatively high, and uses special material
Waste water caused by wine brewing process needs specific catalyst just to can be carried out degradation, has certain limitation.
When cavitation refers to that local pressure declines in liquid, liquid internal or liquid consolidate the formation of gas cavities on interface, hair
The process opened up and crumbled and fall.When fluid pressure be down to Liquid saturated vapor even it is following when, due to liquid it is violent vaporize and produce
Raw a large amount of cavitation bubbles.Cavitation bubble is with liquid flow board expansion, growth.When fluid pressure restore when, cavitation bubble moment crumble and fall to be formed it is micro-
Jet stream and shock wave generate moment localized hyperthermia and instantaneous pressure.The energy of cavitation phenomenon release can also be used, with reality
Now to the reinforcing of the processes such as chemistry, physics, reach synergy, energy conservation, consumption reduction and other effects.Principle is that Hydrodynamic cavitation is produced in the process
A large amount of high activity OH can chemical substance in oxidized waste water, very high temperature high pressure can make the chemical bond rupture in molecule to
Achieve the purpose that larger molecular organics of degrading.
Show that Hydrodynamic cavitation can effectively be handled waste water according to existing investigative technique.It is handled and is made using Hydrodynamic cavitation
Wine waste water, be able to solve existing wastewater method there are the problem of.But Hydrodynamic cavitation reactor conventional at present is single
