Description
Technical field
The utility model relates to a kind of industrial waste water disposal device, particularly relates to a kind of submerged cryogenic Cement Composite Treated by Plasma waste water plant.
Background technology
Poisonous organic wastewater with difficult degradation thereby process is difficult point and the emphasis in water environment protection field.Traditional biochemical process, Physical and chemical method purification techniques are difficult to effectively to meet the requirement and target that purify such waste water quality under certain condition.Plasma technique is ultrasonic, the many kinds of substance such as shockwave, ozone, ultraviolet, high-energy electron, atom and living radical (OH, H, O, N) that utilize high pressure pulse discharge to be formed, the C-C key in Organic Pollutants In Water and phenyl ring can be made to rupture, larger molecular organics changes small-molecule substance into, or make the venomous injurant in waste water be changed into nontoxic material or the low harmful substances of low toxicity, even exhaustive oxidation becomes CO
2, H
2o and inorganic salt, thus pollutent is degraded removal.Plasma technique, as a kind of emerging environmentally friendly advanced electrochemical oxidation process, has the wide and processing efficiency advantages of higher of no pollution, low emission, suitability, is day by day subject to people's attention in field of waste water treatment.
At present, utilize high pressure pulse discharge to produce Cement Composite Treated by Plasma used water difficult to degradate and there are three kinds of forms, i.e. gas phase discharges plasma body, pure discharge in water plasma body and gas-liquid two-phase mixtures discharge plasma.Wherein, gas phase discharges plasma technique is comparatively common at present, because electric discharge occurs in gaseous environment, affect little by water body specific conductivity, but the density of water is much larger than density of air, when the active substance that discharge plasma produces is entered water body by air, resistance is comparatively large, and the life-span of high energy particle is very short, the effective constituent causing a large amount of active substance to be difficult to fully to enter in water or to enter in water, based on ozone, affects water treatment effect.The discharging plasma reactor of gas-liquid two-phase mixing, general processed water body is positioned between electrode, cause the conductivity of water body to generate impact to discharge plasma state and active substance comparatively large, therefore this reactor is poor to electroconductibility good water body treatment effect.In addition, the sparking voltage of gas phase discharges and gas-liquid two-phase mixtures discharge plasma technique be not direct effect on the water, to the contact of water pollutant with react limited, thus reduce waste water treatment efficiency.
For solving the problem, normally exoelectrical reaction changed into and carrying out under water, the plasma body of generation directly processes the pollutent in waste water.Propose hollow metal kapillary in " a kind of enhancement type kapillary needle-discharging plasma body water treatment device " disclosed in domestic application numbers 201210417958.1 to discharge under water as power electrode, strengthening water treatment effect, but select the high-voltage power supply of 1kV ~ 30kV to limit the application of this technology.
Propose to utilize high-voltage pulse power source to discharge under water in " underwater plasma processing apparatus and utilize the system and method for its process ship pressure Cang Shui " disclosed in domestic application numbers 200880019551.5 and produce plasma body to carry out sterilization deactivation to water ballast, working gas is the one in air, oxygen, nitrogen, argon gas and gas mixture thereof, and the method also exists and utilizes the problems such as high-voltage power supply and electrode are easily corroded.
Conventional cryogenic Cement Composite Treated by Plasma waste water utilizes high-voltage pulse power source to discharge to working medium (air, oxygen, nitrogen, argon gas etc.), and the material such as ozone, ultraviolet, high-energy electron, hydroxyl radical free radical that electric discharge produces enters in the aqueous solution degrades to pollutent.Because the oxidation capacity (as hydroxyl radical free radical oxidizing potential 2.80V, ozone 2.07V, hydrogen peroxide 1.78V, Sauerstoffatom 1.23V) of different substances there are differences, cause the material that the pollutent in waste water can not be completely strong with oxidation capacity fully to contact, there is insufficient, the halfway phenomenon of oxidation.
1961, the Hickling of Britain found contact glow discharge electrolysis phenomenon.Contacting glow is when anode and negative electrode apply voltage, vaporize due to the effect of joule heating at the water of the liquid state of ate electrode, make to form a gas zones between anode and electrolyte solution, continue boosted voltage, gas is breakdown, forms glow discharge plasma.High energy active substance moves to bulk solution from plasmasphere under strong electrical forces effect, and high energy particle both interacted, and can react with Pollutants in Wastewater again simultaneously.Whole process can by as follows:

Can find out, traditional plasma body produces plasma body by high pressure to geseous discharge, plasma body enters waste water by effect of mass transmitting and processes pollutent, there is plasma unstable, free radical can not be effectively utilised in time, voltage and energy consumption cross the problems such as high.Contacting glow technology is directly discharged under normal temperature and pressure and low voltage under water, and the high energy active substance of generation, based on the strong hydroxyl radical free radical of oxidisability, greatly improves the degradation efficiency of Pollutants in Wastewater.Therefore, a kind of novel uniform and stable, removal efficiency is high and cost is low contacting glow water treatment method is developed and device has very important significance.
