Standing wave mixing combining ultrasonic sewage disposal device
Technical field
This utility model relates to sewage disposal technology, particularly a kind of standing wave mixing combining ultrasonic sewage disposal device.
Background technology
Along with developing rapidly of the industries such as printing and dyeing, papermaking, the generation amount of the harmful waste water of high-concentration hardly-degradable increases the most day by day.Along with the raising of people's living standard, the requirement to environment is more and more higher.The standard about sewage discharge that country puts into effect is the strictest, and sewage disposal becomes the problem that have to solve in enterprise's existence and development.At present main or conventional biochemical process is processed for high-concentration hardly-degradable organic pollution.The secondary pollution not only resulting in environment in the process utilizing biochemical process to process sewage the most also can produce substantial amounts of mud.It is to say, only that Treatment of Sludge is good, the process of whole sewage could be properly completed.And the processing cost of mud occupies more than the 60% of whole sewage disposal.Along with acoustochemical rise, the ultrasonic visual field entering people as a kind of novel water technology.Supersound process sewage is based primarily upon ultrasonic " cavitation effect ", cavitation nucleus can produce the high temperature of 5000K, the high pressure of more than 100MPa in local in the moment of collapse, these energy be enough to rupture the chemical bond of organic macromolecule, H and OH can also be split water into simultaneously, oxidation operation in water can be become carbon dioxide and water by OH, water can also be become supercritical water by localized hyperthermia's high pressure that ultrasonic cavitation simultaneously provides, supercritical water is a kind of ideal reaction medium, can accelerate the speed of chemical reaction.Based on above-mentioned cavitation effect, free-radical oxidation and supercritical water, supersonic frequency, power, time suitably in the case of, ultrasonic poisonous larger molecular organicses all in water can be oxidized to carbon dioxide, water and other simple substance.Compared to traditional biochemical process, ultrasonic water technology also has a series of advantage, simple to operate, applied widely, do not produce secondary pollution, the most ultrasonic can also be used in combination with methods such as other technology such as ozone, can greatly improve treatment effect.Current ultrasonic water treatment facilities has a variety of, but all deposits some problems: some device uses single-frequency, and the cavitation bubble effect intensity of generation is weak, it is impossible to complete the process to different size organic molecule and cell;Ultrasonic and other method are used in combination process water by some device, although cavitation effect and cell wall breaking effect all improve, but bring secondary pollution;Some water treatment facilities are also had now to use frequency mixing ultrasonic, ultrasonic compared to single-frequency, frequency mixing ultrasonic can be produced frequency complicated and changeable by approach such as frequency multiplication, frequency dividing ripples and be produced more cavitation effect, much better to the degradation effect of various sizes of larger molecular organics and the shell-broken effect of various sizes of cell.But occurring the least flocculent substance in the sewage after ultrasonication, after these flocculent substances need precipitation to remove, water processes and can complete.If taking long enough by natural sedimentation, adding chemical agent and can accelerate precipitation, but secondary pollution can be introduced.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is just to provide a kind of standing wave mixing combining ultrasonic sewage disposal device, can effectively solve effective process problem of sewage.
The technical scheme that this utility model solves is, standing-wave ultrasonic and frequency mixing ultrasonic are used in combination process sewage.According to ultrasound wave isolation technics principle, being in the suspended material in ultrasonic standing wave field can move, assembles under the common effect of acoustic radiation force, buoyancy, gravity and liquid sticky resistance at the nodal plane in stationary field.Little flocculent substance can become big floccule at ripple interface aggregates under the effect of standing wave, is combined with frequency mixing ultrasonic by standing-wave ultrasonic and processes sewage.Accordingly, this utility model includes cell body, cell body is to be connected with frequency mixing ultrasonic reaction vessel through first passage by standing-wave ultrasonic reaction vessel to constitute, and equipped with frequency and a frequency first identical ultrasonic transducer of uniform symmetry on the inwall of standing-wave ultrasonic reaction vessel two correspondence, constitutes standing-wave sound field;Equipped with frequency and a frequency different ultrasonic transducer of uniform symmetry in frequency mixing ultrasonic reaction vessel inner face surrounding, constitute mixing sound field, water inlet is had on standing-wave ultrasonic reaction vessel, there is outlet on frequency mixing ultrasonic reaction vessel, constitute standing-wave ultrasonic and combine the process structure to sewage with frequency mixing ultrasonic.
This utility model simple in construction, easy to operate, use standing-wave ultrasonic to be used in combination with frequency mixing ultrasonic, be effectively increased the treatment effect to sewage, non-secondary pollution, energy-conserving and environment-protective, economic and social benefit is notable.
