Generally, most of the existing organic solid processing is performed in the manner of digesting organic solids by anaerobic or aerobic microbes, to achieve the effect of decreasing the quantity of their solids. But, such biological digestionprocess costs substantially long time. To be able to shorten the period required by the biological digestion procedure, a chemical or physical pretreatment is mostly adopted. The pretreatment is used to decompose or crack the organic solids from large moleculesto tiny molecules, so as to boost the digestion speed of their aerobic or adrenal glands, and efficiently shorten the general digestion period of the organic solids.
A well-known and common chemical pretreatment method is a method of alkaline hydrolysis, which contains the following steps. An organic solid is guided into a processing tank, precipitated and hydrolyzed by adding alkali, then dried forrecovery. However, the overall processing time of this organic sound is increased. The added compound will not only increase salts in the first organic strong, but in addition may cause secondary damage on environment, such as chemical contamination. Therefore,the compound pretreatment should be carried out very cautiously, and thus the application of this chemical pretreatment is always restricted. Additionally, organic fertilization cannot be attained after performing the chemical pretreatment, and so the value ofthe natural strong following treatment is diminished.
Further, well-known and common physical pretreatment procedures generally crack by means of giving outside forces, and the most frequent method includes the following measures. A natural solid is blended with water, and then hydrolyzed by employing anultrasonic wave, to crack the organics from the organic solids by means of the energy of the ultrasonic wave from the water, so as to ease the digestion of the aerobic or adrenal glands, thus reducing the overall digestion period of their organicsolids.
Briefly, the bodily pretreatment by cracking with an ultrasonic wave may stop the secondary environment pollution which might be due to chemical pretreatment, but the generation of the thoracic system needs to be driven by an external powersupply, especially for treatment of a huge quantity of organic solids, which will surely consume a great deal of power. Therefore, it is always a goal for related manufacturers to try to find a means or means effective at reducing theoperation time of ultrasonic wave while preserving the same cracking efficiency of the ultrasonic wave or effective at achieving a greater efficiency of organic good hydrolysis with exactly the same performance time of ultrasonic wave.
