Daim ntawv thov cov dej khib nyiab yog qhov kev txhim kho yav tom ntej ntawm kev kho cov kav dej thiab tseem yog qhov yuav tsum tau ua rau tib neeg txoj kev loj hlob ruaj khov. Cov khoom siv raw muab rho tawm los ntawm cov dej phwj lossis sludge, xws li cov ntxhia thiab phospholipids, tuaj yeem siv los ua cov khoom siv yooj yim rau kev luam ntawv thiab xim, lub ntsiab adsorbents, thiab biological flocculants. Lawv siv rau hauv kev kho dej, kev ua liaj ua teb, kev cog qoob loo, kev lag luam ntawv, kev kho mob, kev tsim kho kev lag luam, thiab ntau lwm daim teb thiab muaj qhov tseem ceeb heev. Rov ua dua tshiab tus nqi.
(surfactant)
Muaj ntau hom kab mob me me hauv cov sludge seem. f, cov khoom muab rho tawm los ntawm nws yuav tsum yog kev sib xyaw ntawm ntau yam tshuaj polymer. Txawm hais tias lawv yog cov khoom siv intracellular lossis extracellular polymer, lawv txhua tus muaj cov pab pawg nquag sib xws, xws li carboxyl, hydroxyl, thiab phosphate. Pab pawg thiab lwm pab pawg muaj txiaj ntsig. Lub xub ntiag ntawm cov pab pawg no tso cai rau cov khoom siv polymer tshem tawm los ua cov khoom siv hnyav hlau ion adsorbents.
Raws li kev kho mob huv si, Ultrasonic yoj tsis tas yuav tsum tau ntxiv cov tshuaj lom neeg thaum lub sijhawm txheej txheem thiab yuav tsis ua rau muaj kuab paug ntxiv. Ultrasonic nthwv dej tuaj yeem faib cov flocs hauv theem dej, Thiab cov nyhuv cavitation tuaj yeem rhuav tshem cov khoom loj rau hauv cov khoom me me. Ultrasound yog lub zog kho lub zog, Thiab nws qhov kev tsis zoo tshaj plaws yog nws txoj kev siv hluav taws xob siab, Uas txwv qhov ua tau ntawm kev siv tswv yim. Surfactant muaj cov nyhuv solubilizing nyhuv, Uas tuaj yeem ntxuav cov protein ntawm lub cell membrane, Txhim kho permeability ntawm lub cell membrane los ntawm kev cuam tshuam rau osmotic siab, Thiab nce qhov kev puas tsuaj rau sludge floc. In addition, surfactant activity can advertise the extraction of EPS from remaining sludge, change the cell structure, and affect sludge residential properties.
Surfactant-enhanced ultrasonic approaches can be made use of to remove natural polymer materials and as a pretreatment technique to lower energy consumption. The boost in the extraction amount of PSs from the continuing to be sludge under the activity of surfactant-enhanced ultrasound results from the launch of raw material because of floc fragmentation and cell dissolution.

Ua ntej, surfactants, such as anionic (such as salt dodecyl sulfate, SDS) and cationic (such as cetyltrimethylammonium bromide, CTAB), are made use of to boost the relationship in between sludge and polymer materials. Communications in between. They can lower the surface stress of sludge, making it less complicated for polymer materials to divide from sludge.
Subsequently, ultrasound is introduced to boost the removal impact better. The strong vibration and shock waves produced by ultrasonic waves can damage the structure of sludge and tear cell walls, thereby launching more polymer substances. Additionally, ultrasound can likewise promote the interaction in between surfactants and polymer materials, making the removal process extra effective.
Throughout the removal procedure, it is likewise necessary to optimize the experimental parameters, such as the frequency, lub zog, and action time of ultrasonic waves, to achieve the most effective extraction effect.

In general, surfactant-enhanced ultrasonic extraction of polymer materials in residual sludge is a reliable and cutting-edge method. It not just boosts extraction performance yet additionally assists expand the scope of resource utilization of staying sludge, offering new possibilities for the growth of sewage therapy and resource recuperation fields. Txawm li cas los xij, the practical application of this method needs further research study and optimization to address possible technological difficulties and financial problems.
