Wastewater resource application is the future development direction of sewer treatment and is likewise an unpreventable need for sustainable human growth. Raw material drawn out from sewage or sludge, such as minerals and phospholipids, can be utilized as printing and coloring basic materials, main adsorbents, and biological flocculants. It is utilized in water treatment, agriculture, cultivation, the paper market, treatment, the building market, and various other areas and has fantastic relevance. Reusing value.

There are lots of kinds of microbes in the remaining sludge. No reira, the materials drawn out from it should be a mixture of numerous polymer substances. Whether they are intracellular or extracellular polymer materials, they all have common energetic teams, such as carboxyl, hydroxyl, and phosphate. Nga roopu me etahi atu roopu whai hua. Ko te noho mai o enei roopu ka taea te whakamahi i nga rauemi polymer kua tangohia hei whakaurunga katote whakarewa nui..
Ka rite ki te rongoa hangarau hou, e kore e ngaru ultrasonic karanga mo te tāpiritanga o matū puta noa i te mahi, me te kore e whakaoho atu contamination. Ka taea e nga ngaru Ultrasonic te tohatoha flocs i roto i te waahanga wai, a ka taea e te hua cavitation te wawahi i nga kongakonga nui ki nga matūriki iti. Ko te ultrasound he tikanga maimoatanga kaha-kaha, a ko tana raru nui ko te kaha o te whakamahi kaha, e whakaiti ana i te whai waahi o nga tono whai hua. Ko te Surfactant he awe whakarewa, e taea te horoi atu i nga pūmua i runga i te membrane pūtau, te whakarei ake i te uruhanga o te membrane pūtau ma te pa ki te ahotea osmotic, me te whakanui ake i te kino o te kahui para. I tua atu, 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.

Tuatahi, nga hauhautanga, 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, kia iti ake te uaua mo nga rauemi polymer ki te wehe mai i te paru.
I muri mai, ka whakauruhia te ultrasound ki te whakanui ake i te painga o te tangohanga. Ko te kaha o te wiri me nga ngaru ohorere ka puta mai i nga ngaru ultrasonic ka pakaru te hanganga o nga pakitara o te paru me te pakaru., na reira ka nui ake nga matū polymer. I tua atu, Ka taea hoki e te ultrasound te whakatairanga i te taunekeneke i waenga i nga haumanu me nga rauemi polymer, kia whai hua ake te tukanga tangohanga.
I roto i te tukanga tangohanga, he mea tika ano kia arotau nga tawhā whakamatautau, penei i te auau, mana, me te wa mahi o nga ngaru ultrasonic, ki te whakatutuki i te painga tangohanga tino whai hua.

I te nuinga, Ko te tangohanga ultrasonic-whakarei o nga rauemi polymer i roto i te toenga o te paru he tikanga pono me te tapahi-mata.. Ehara i te mea ka whakanui noa i nga mahi tangohanga engari ka awhina ano hoki ki te whakawhānui ake i te whānuitanga o te whakamahi rauemi mo te noho paru., te tuku huarahi hou mo te tipu o te rongoa parapara me nga waahi whakaora rawa. Heoi ano, ko te whakamahinga whaihua o tenei tikanga me rangahau rangahau me te arotautanga hei whakatika i nga uauatanga hangarau me nga raruraru putea.
