Reverse osmosis (RO) ukuphinda kusetyenziswe amanzi agxininisiweyo

Reverse osmosis (RO)ukusetyenziswa kwakhona kwamanzi okugxininiswe

Nokuba kukulungiswa kwamanzi acocekileyo okanye ukusetyenziswa kwakhona kwamanzi amdaka kwimizi-mveliso, ngelixa kusetyenziswa itekhnoloji ye-reverse osmosis (RO), kunyanzelekile ukuba ivelise umlinganiselo othile wamanzi azingiweyo. Ngenxa yomgaqo osebenzayo we-osmosis eguquguqukayo, amanzi agxininiswe kule nxalenye ahlala eneempawu zetyuwa ephezulu, i-silica ephezulu, i-organic matter ephezulu, ubunzima obuphezulu kunye nokunye. Ngenxa yeempawu ezinjalo, sihlala sidinga ukukhetha imilinganiselo ethile yamanzi agxininisiweyo ngokwemeko ethile, ukuze sigweme ukuchitha izibonelelo zamanzi kwaye sifumane injongo yokunciphisa iindleko kunye nokwandisa ukusebenza kakuhle.

Okokuqala, iindlela eziqhelekileyo zokucocwa kwamanzi okulungiswa kwamanzi acocekileyo:

① Ukukhutshwa okuthe ngqo kwangaphandle (konke ukukhutshwa kwangaphandle) : kuxhaphake kwisixhobo esincinci samanzi acocekileyo, amanzi ompompo njengamanzi akrwada, amanzi agxininiswe ngokuthe ngqo amanqanaba amathathu okukhutshwa.

Izizathu eziphambili: umgangatho wamanzi akrwada ulungile, izikhombisi zamanzi ezigxininisiweyo zinokuhlangabezana nemigangatho yokukhupha; Izinga lokuhamba lincinci kwaye alinalo ixabiso lezoqoqosho lokusetyenziswa kwesibini kwangaphambili (xa kuthelekiswa nexabiso lamanzi akrwada)

Qaphela: Kwezinye iimeko, amanzi agxininisiweyo angaxutywa namanzi akrwada omgangatho ongcono (ukunciphisa ukuxinana kwezalathi ezithile) ukuhlangabezana nemigangatho yokukhutshelwa kwenqanaba eliphezulu. Inkqubo inokunciphisa ukuxinwa kwamanzi agxininisiweyo ngokunciphisa izinga lokubuyisela.

② Ukurisayikilishwa (ukuqokelelwa ngokuyinxenye kunye nonyango) : kuxhaphake kwisixhobo esingaphezulu esiphakathi okanye iiprojekthi, iimfuno zokubuyisela inkqubo ziphezulu, amanzi agxininiswe emva kokulungiswa kwangaphambili okanye isixhobo se-ROR, kwinkqubo ephambili, ukurisayikilishwa, ukuphucula izinga lokubuyisela. Umlinganiselo othile wamanzi agxininisiweyo (kubandakanywa nawo onke amanzi agxininiswe kakhulu) aqokelelwa kwaye acocwe, kwaye akanakukhutshelwa ngokuthe ngqo.

Izizathu eziphambili: izinga lokubuyisela inkqubo liphezulu, izinga lokubuyisela indlela enye ayikwazi ukuhlangabezana neemfuno zokubuyisela ngokupheleleyo; Iimfuno zokukhusela indalo ziphezulu, zifuna umlinganiselo ophezulu wemithombo yamanzi. Ukurisayiklishwa kwamanzi agxininisiweyo kwandisa ityuwa kunye nezinye izikhombisi ngokungenasiphelo, kwaye amanzi azinzile (amanzi agxininiswe kakhulu) kufuneka akhutshwe rhoqo ukuze afezekise ukusebenza okuzinzile kwenkqubo. Iimpawu zale nxalenye yamanzi adibeneyo zihlala zidlula imigangatho emithathu yokukhupha kwaye kufuneka ziqokelelwe kwaye zicocwe.

Ukulungiswa kwamanzi agxininisiweyo: Ngokweempawu ezine zamanzi agxininisiweyo, adityaniswe nemeko yokwenyani, ukuhluzwa ngoomatshini, ukuthambisa kunye namanye amanyathelo ayenziwa, ukuze amanzi agxininiswe ngaphambili aphathwe ngokusisiseko ahlangabezane nemigangatho yomgangatho wamanzi amanzi akrwada, faka. itanki yoqobo (iphuli), kwaye iphinde isetyenziswe.

Isixhobo se-ROR: Emva kokucocwa ngokufanelekileyo kwamanzi agxininisiweyo, isixhobo se-RO esongezelelweyo sisetyenziselwa unyango, kwaye amanzi acociweyo avelisiweyo (anokuthi angahlangabezani nomgangatho womgangatho wamanzi wamanzi acocekileyo) angena kwitanki yokuqala ukuze asetyenziswe kwakhona. Amanzi agxininiswe kakhulu awenziwe sisixhobo se-ROR akakwazi ukukhutshwa ngokuthe ngqo kwaye kufuneka aqokelelwe kwaye aphathwe.

Ukulungiswa kwamanzi agxininisiweyo: Ngokweempawu ezine zamanzi agxininisiweyo, adityaniswe nemeko yokwenyani, ukuhluzwa ngoomatshini, ukuthambisa kunye namanye amanyathelo ayenziwa, ukuze amanzi agxininiswe ngaphambili aphathwe ngokusisiseko ahlangabezane nemigangatho yomgangatho wamanzi amanzi akrwada, faka. itanki yoqobo (iphuli), kwaye iphinde isetyenziswe.

Isixhobo se-ROR: Emva kokucocwa ngokufanelekileyo kwamanzi agxininisiweyo, okongeziweyoIsixhobo se-ROisetyenziselwa unyango, kwaye amanzi acociweyo aveliswayo (anokuthi angafikeleli umgangatho wamanzi acocekileyo) angena kwitanki yokuqala ukuze aphinde asetyenziswe. Amanzi agxininiswe kakhulu awenziwe sisixhobo se-ROR akakwazi ukukhutshwa ngokuthe ngqo kwaye kufuneka aqokelelwe kwaye aphathwe.

Chaza ngokufutshane iingenelo kunye nokungalunganga kwendlela nganye yonyango kunyango lwamanzi amdaka

Ukuphinda kusetyenziswe amanzi: inkqubo yokucoca i-ultrafiltration + reverse osmosis (UF+RO), izinga lokubuyisela elipheleleyo lama-50%, amanzi asele egxininiswe afuna unyango olongezelelweyo.

I-evaporator yobushushu obuphantsi: unyango lwe-vacuum yobushushu obuphantsi, umthamo omncinci wokucubungula, ngokubanzi 200L/H-- 3000L/H amandla okusebenza. Iarhente yokucoca eqhelekileyo, amanzi amdaka e-electroplating, ukusika amanzi amdaka amdaka kunye nolunye ulwelo olusekwe ngoomatshini, ubushushu obusebenzayo bumalunga nama-30.℃.

I-evaporator ye-MVR: Ukudityaniswa kobushushu obuphantsi kunye noxinzelelo oluphantsi lwetekhnoloji yokuphuphuma komphunga, umthamo wokucutshungulwa okuphakathi, amandla okusebenza ngokubanzi ngaphezulu kwe-0.5T/H. Ixhaphakile kwiikhemikhali, ukutya, iphepha, iyeza, ukuchithwa kwamanzi olwandle kunye nezinye iindawo, ubushushu bokusebenza ngokubanzi be-70-90℃.

I-evaporator ye-multi-effect: I-evaporator yesiqhelo yobushushu obuphezulu, ngokusetyenziswa ngokuphindaphindiweyo komphunga ukuphucula ukusetyenziswa kakuhle kwamandla, kunye ne-evaporator kunye ne-condenser yamacandelo amabini, inkqubo izinzile, ukusetyenziswa kwamandla aphezulu, kufuneka kuxhotyiswe ngenkqubo yomphunga ( kukho isixhobo esahlukileyo sejenereyitha yomphunga).

Ukunyangwa kokukhutshwa kwamanzi: Ukubunjwa kwamanzi amdaka kwahlukile, ummandla uhlukile, iindleko zonyango zihlukile, kwaye ixabiso leyunithi ngetoni nganye ukusuka kumakhulu ukuya kumawaka.

Ngokhetho olubanzi lweendlela ezingentla, inokusetyenziswa yodwa okanye ngokudibeneyo ukufezekisa injongo yokunciphisa iindleko kunye nokwandisa ukusebenza kakuhle.
