Description
Affiliated technical field
The present invention relates to sewage disposal device, relate in particular to a kind of pretreated device that cracks of excess sludge that is used for.
Background technology
The back-end processing mode of excess sludge generally includes thickening, anaerobic digestion and is back to the aerobic aeration system carries out biology and handles, yet the water-wet behavior of active sludge and flco structure make dehydration very difficult, and a large amount of existence of microorganism are restricted the speed of reaction of anaerobic digestion hydrolysis stage, make the digestion residence time long, the digester body is bulky and methane production is lower.Studies show that cracking of mud can promote mud decrement effectively, improves dewatering, improves the anaerobic digestion hydrolysis rate and increase methane production.Breaking sludge structure and cell walls change mud flco structure, and cell content flows out and enters water, become the dissolved matter of solidity material into easily degrading of difficult degradation, thereby improve the back segment processing efficiency of active sludge.At present, the sludge disintegration technology comprises various physical chemistry treatment process, and wherein pyrolysis, machinery cracks, ultrasonic, ozone oxidation, acidifying, alkaline hydrolysis, alkali and ultrasonic in combination application etc.In these treatment processs, ultrasonic wave because of have environmental sound, need not to add any reagent, easy and simple to handle and take up an area of the important method that advantage such as few becomes sludge disintegration.
Summary of the invention
The purpose of this invention is to provide a kind of can realize continuously automatically operation and instrument state monitor, shorten the time of cracking, simple in structure, easy and simple to handle, noiseless mud in real time, do not need to offer medicine and heating, non-corrosiveness and not the sludge through ultrasonic waves of blocking pipe crack device.
Purpose of the present invention can realize by following measure:
1. adopt the low-frequency ultrasonic waves of 20kHz that mud is cracked, efficient is higher.The low frequency ultrasound wave energy produces powerful mechanical shear stress, can efficiently destroy cell walls, shortens the time of cracking greatly.
Ultrasonic power and action time adjustable, set ultrasonic energy according to the difference of sludge concentration.By the timer setting, can realize the moving row of automatization.Simultaneously, set up digital display reometer and voltmeter, the time grasp the real-time working state of ultrasonic unit, and adopt the casing aeration structure, increase the thermal diffusivity of producer, guarantee the continuous operation of device.
3. for overcoming the electric energy acoustic energy transformation efficiency lower shortcoming of existing ultrasonic transducer with steel or aluminium alloy, the present invention has adopted the MS73 titanium alloy material with ultrasound probe, to improve the efficient that electric energy is converted to acoustic energy, the power loss that the mud temperature raises and causes during minimizing work, its energy conversion relation is seen Fig. 2.
4. the present invention adopts the soundproof box design, and the high-frequency sound of generation is to the harm of HUMAN HEALTH when working to reduce ultrasound probe.
5. be equipped with the vertical-flow cell body design of plate washer, both guaranteed the continuous conveying operation of mud, increase mud residence time in groove again, thereby raising sludge disintegration degree and shortening crack the time.
Behind a kind of probe type ultrasonic device breaking sludge of the present invention; promote the fast and stable of mud; shorten anaerobic digestion time and improve methane production; improve the dewatering of mud; and the carbon source that the mud leachate also can be used as dephosphorization denitrogenation enters biochemistry pool and by biological directly utilization, realizes mud decrement, has both avoided secondary pollution; protect environment, reached the purpose of turning bane into boon, turning waste into wealth again.
