Description
Technical field
This practicality is newly related to a kind of device of supersonic synergic electro-hydraulic impulse method degrading high concentration organic wastewater, belongs to pollution
Technical field of water body purification.
Background technology
With expanding economy, China is faced with shortage and the serious environmental problem of water pollution of water resource.China prints
The high concentration hard-degraded organic waste water CODcr discharge capacitys such as dye, pharmacy, chemical industry, light industry, agricultural chemicals, cultivation, coal chemical industry are big, phenols,
The heterocycles such as naphthalene, pyridine, quinoline and polycyclc aromatic compound species are more.Counted according to environmental aspect publication in 2007, annual emissions
More than 10,000,000,000 t, more than the 30% of the water body receiving total amount of pollutant is accounted for, and be incremented by with 2.2% average speed.And traditional life
Thing treatment technology is difficult to meet increasingly complicated water treatment requirement, makes a large amount of for the handle or incomplete difficult degradation of processing
Organic pollution enters strong influence water ecological environment after water body environment, threatens human health.

There is specific use condition, when organic concentration is middle low-level, can just use such a method, and have for high concentration
Machine used water difficult to degradate, and for the very high coking chemical waste water of organic concentration, dyeing waste water etc., need to dilute stoste in water inlet
Several times or even hundred times, required clear water, power consumption are big, cause processing cost to increase.
Pre-treatment-anaerobic-aerobic group technology：Technique more common at present, but because its high anaerobic and aerobic reacts
The condition requirement of device, production is built to it and equipment requirement is higher.
Membrane filtration technique and absorption method are because the excessive concentration of dirty Organic substance in water is easily contaminated film, filtration yield
It is gradually reduced over time, it is relatively on the low side in practice.
Although catalytic wet method purification efficiency is higher, cost is added due to catalyst to be added, while catalyst
Reclaim difficulty, secondary pollution can be caused.As can be seen here, all exist necessarily to concentration organic wastewater disposal process at present
Deficiency, thus find it is a kind of efficiently, it is simple while avoid the processing method of secondary pollution extremely urgent.
With ultrasonic wave (frequency>16 kHz) chemical pollutant especially difficult degradation organic contamination in technical finesse degradation water
The application of thing makes great progress.It is a new water technology.Collect high temperature pyrolysis, advanced oxidation and overcritical
The multiple technologies such as oxidation are, high, applied widely with degradation efficiency, and can be with other water technology synergy
The advantages of.Many valuable achievements in research are achieved in terms of enhancing degradation or directly degraded Organic Pollutants In Water.It is super
H and OH free radicals caused by acoustic cavitation, have a very strong oxidability, can further trigger organic molecule chain rupture, from
Transfer and redox reaction by base.Make the degraded of indissoluble solution, larger molecular organicses under normal condition.
Electro-hydraulic impulse is to be converted directly into electric energy to surge force-disturbance and act on the mechanical energy of water body, electro-hydraulic impulse
Electric discharge processing waste water is to puncture the main gap of reative cell using high voltage, and the energy abrupt release for being stored in capacitor comes out
Pulse voltage is produced, so that the organic matter in waste water is degraded.
Electro-hydraulic impulse is straight by the high voltage for producing 4-1000kV after high-tension transformer, high voltage silicon rectifier stack, current-limiting resistance
Stream electricity, high-tension application, the high-strength electric field of two interpolars, which makes electronics moment obtain energy, turns into high energy electron, makes water with water collision
Molecular dissociation, produce OH, HO2, O, H, H2O2Isoreactivity species, these active species are in water with organic matter reaction
Organic matter degradation；Ionization, transition in discharge process due to molecule can produce some physical effects, such as ultraviolet, ultrasound, punching
Hit the degraded that ripple, localized hyperthermia etc. have further speeded up organic matter.As can be seen here, electro-hydraulic impulse electric discharge is that collection is various advanced
The new water technology of oxidation technology.Because this law is despite high voltage operation state, but because being pulsed discharge, therefore
Power consumption is few.
Ultrasonic method, electro-hydraulic impulse hair can produce free radical in normal work, the effect under conditions of blast aeration
The advantages of particularly good, and ultrasonic method can be with other water technology synergy, therefore at supersonic synergic electro-hydraulic impulse method
Reason technology is all higher than any one simple method efficiency, and its United Technologies is far beyond simple ultrasonic method, electro-hydraulic impulse
The superposition of method.The advantages of with high treating effect, non-selectivity, non-secondary pollution, what electro-hydraulic impulse applied is pulse voltage,
Saved for the processing of other electrolysis.Therefore, supersonic synergic electro-hydraulic impulse method processing organic wastewater be it is a kind of very
There is the new technology of development potentiality.
