Wastewater resource application is the future advancement direction of sewage therapy and is likewise an inevitable need for lasting human growth. Raw material extracted from sewage or sludge, such as minerals and phospholipids, can be utilized as printing and coloring resources, main adsorbents, and biological flocculants. It is utilized in water treatment, agriculture, cultivation, the paper industry, medical care, the building and construction market, and other fields and has terrific significance. Reusing value.


There are several kinds of microorganisms in the staying sludge. As a result, the materials removed from it must be a combination of different polymer substances. Whether they are intracellular or extracellular polymer compounds, they all have typical active groups, such as carboxyl, hydroxyl, and phosphate. Groups and various other functional groups. The presence of these groups enables the extracted polymer materials to be used as heavy steel ion adsorbents.

As a tidy treatment innovation, ultrasonic waves do not need the enhancement of chemicals throughout the activity and will certainly not trigger additional pollution. Ultrasonic waves can distribute flocs in the water stage, and the cavitation effect can damage large particles into small particles. Ultrasound is an energy-intensive therapy method, and its greatest disadvantage is its high energy usage, which restricts the possibility of useful applications. Surfactant has a solubilizing impact, which can clean off proteins on the cell membrane, enhance the permeability of the cell membrane layer by impacting the osmotic stress, and intensify the damage to the sludge floc. Furthermore, surfactant activity can promote the extraction of EPS from continuing to be sludge, alter the cell structure, and impact sludge buildings.

Surfactant-enhanced ultrasonic approaches can be used to remove all-natural polymer products and as a pretreatment method to decrease power intake. The rise in the extraction quantity of PSs from the staying sludge under the action of surfactant-enhanced ultrasound results from the launch of organic matter due to floc fragmentation and cell dissolution.


First, surfactants, such as anionic (such as salt dodecyl sulfate, SDS) and cationic (such as cetyltrimethylammonium bromide, CTAB), are used to improve the connection in between sludge and polymer compounds. Communications between. They can reduce the surface area stress of sludge, making it simpler for polymer materials to divide from sludge.

Subsequently, ultrasound is introduced to improve the removal result better. The strong resonance and shock waves created by ultrasonic waves can destroy the framework of sludge and tear cell walls, thereby launching more polymer materials. Furthermore, ultrasound can also advertise the communication in between surfactants and polymer materials, making the removal procedure much more effective.

During the extraction procedure, it is likewise essential to maximize the speculative criteria, such as the frequency, power, and activity time of ultrasonic waves, to attain the most effective extraction impact.


In general, surfactant-enhanced ultrasonic extraction of polymer substances in residual sludge is an effective and innovative technique. It not just boosts removal performance however additionally helps expand the extent of resource usage of staying sludge, providing new possibilities for the development of sewer therapy and source healing areas. However, the useful application of this method requires more research and optimization to solve feasible technical troubles and financial problems.
