When), the oxidation removals pollutant such as hydroxyl radical free radical and oxidation-reduction pair, ammonium ion present in waste water is catalyzed by microwave energy to be produced
Raw Active Chlorine oxidative degradation.
Waste water after the pre- catalytic treatment of microwave enters ultrasonic reaction area, and under aeration condition, ultrasonic air bubble is rapid
The TRANSIENT HIGH TEMPERATURE high pressure that collapse generates makes hydrone in bubble crack to form H, HO, HO2Equal strong oxidative free radicals, to warp
Pollutant after pre- catalysis targetedly carries out efficient degradation, while when garbage leachate wastewater middle and high concentration ammonia nitrogen exists
When, free ammonia volatilization enters cavitation bubble and is directly pyrolyzed, or by the free-radical oxidation of liquid phase main body, generates N2、N2O evolution, to reach
To thorough degradation.
The water outlet of ultrasonic reaction area is again through strengthening microwave reaction area, by the further enhancing degradation of pollutant remaining in waste water,
So that some remaining inorganic matter such as ammonia nitrogens is decomposed into ammonia and nitrogen, escaped from water, the effect by microwave to waste water small molecule,
Break colloidal solid surface layer moisture film in waste water, promote coagulating sedimentation, accelerates to be separated by solid-liquid separation, to reach dense to garbage percolation liquid film
COD, NH in contracting liquid3The efficient degradation of the pollutants such as-N, coloration.
The catalyst that more metal solid catalyst are reacted as microwave energy, large specific surface area, catalytic activity point is more, activity at
Point dispersion degree is high, dissolution rate is low, high recycling rate, without secondary pollution, and focusing thermal-energy while promotes reactants and products phase
The selectivity of interaction and accelerate reaction process.
The utility model has the advantages that a kind of rubbish percolation liquid membrane concentration liquid processing device disclosed in this invention and its processing method, with
