Nekukurumidza kusimukira kwemaindasitiri uye kugariswa kwemadhorobha, mvura yetsvina yakawandisa yave dambudziko rakakura rezvakatipoteredza. High-concentration wastewater haingori nehuwandu hwezvinhu zvakasvibiswa, inorganic matter, heavy metals nezvimwe zvinhu zvinokuvadza, asiwo kusungirirwa kwayo kunodarika dhizaini uye kugona kwekurapa kwenzvimbo dzakajairwa dzekuchenesa mvura. Naizvozvo, iyo yakanyanya kuwanda yekuchenesa mvura yetsvina uye yakajairwa kubuda kwakakosha zvakanyanya.
1. Tsanangudzo uye maitiro emvura yakasvibiswa yakakwirira-yakanyanya kuwanda kwemvura yakasviba, kazhinji inoreva kusvibiswa kwemvura ine huwandu hwehuwandu hwezvinhu zvakasvibiswa, simbi inorema, chepfu uye inokuvadza uye zvimwe zvinosvibisa. Izvo zvinosvibisa zviri mumvura yetsvina zvinopfuura kure nemvura yetsvina, uye yakaoma kurapa. Inogona kunge iine marudzi akasiyana-siyana ezvinosvibisa, senge organic matter, heavy metals, radioactive substances, etc. Zvimwe zvinosvibisa zvinogona kuita inhibitory effects pama microorganisms uye zvinokanganisa mashandiro ebhayoloji kurapwa, izvo zvinonetsa kubvisa nenzira dzemazuva ose dzebiological treatment.
2. Chiitiko chechizvarwa chepamusoro-yakanyanya kusvibiswa kwemvura Kugadzirwa kwemakemikari: mvura yakasvibiswa inogadzirwa mukugadzirwa kwemakemikari inowanzova nenhamba yakawanda yezvinyorwa, simbi inorema uye zvimwe zvinosvibisa. Indasitiri yemishonga: mvura yetsvina yemishonga inowanzova nehuwandu hwehuwandu hwezvinhu zvehupenyu, mishonga inorwisa mabhakitiriya, nezvimwewo, izvo zvakaoma kurapa. Indasitiri yedhayi nemachira: mvura yetsvina inogadzirwa nemaindasitiri aya kazhinji ine huwandu hukuru hwe biodegradable organic matter uye chromaticity. Electroplating uye metallurgy: Mvura yakasviba ine simbi inorema uye chepfu inogadzirwa panguva ye electroplating uye simbi.
3. Core tekinoroji yemhando yepamusoro-yakaiswa tsvina yemidziyo yekuchenesa mvura yetsvina, kazhinji kuburikidza nemuviri kana kemikari nzira dzekubvisa zvidimbu zvakakura, zvakamiswa zvinhu mumvura yetsvina, kugadzira mamiriro ekurapa kunotevera. Ichashandisawo epamusoro oxidation matekinoroji akadai seFenton oxidation, ozone oxidation, kuburikidza nekugadzirwa kweiyo oxidant yakasimba kushandura refractory organic matter kuita zvinhu zviri nyore kuparara. Shandisa metabolic chiito che microorganisms kubvisa organic zvinhu mumvura ine tsvina. Kune yakakwira-yakadzika tsvina, anaerobic uye aerobic yakasanganiswa maitiro anogona kugamuchirwa kuti avandudze maitiro ekurapa. Iyo tic zvinhu mumvura yetsvina inogona zvakare kubviswa nemaitiro emuviri kuburikidza ne membrane kupatsanurwa matekinoroji senge ultrafiltration uye reverse osmosis. Kuburikidza nekunaya kwemakemikari, ion exchange, adsorption uye imwe heavy metal kurapwa tekinoroji, inoshandiswa kubvisa heavy metal ions mumvura yetsvina. Naizvozvo, kune yakakwira dhizaini yekuchenesa tsvina, zvakakosha kuti uve nechokwadi chekuti tsvina inosvika pachiyero, sarudza zvine musoro nzira yekurapa, nyatso kudzora maitiro ekurapa, kusimbisa pretreatment, optimize maparamita ekushanda uye kugara uchionekwa uye kuongororwa. Kana matambudziko akawanikwa, tora matanho akakodzera nguva yekugadzirisa.
Nekuda kwekusarudzika kwemhando yemvura, yakakwira yekugadziriswa kwemvura yetsvina ine yakasimba tekinoroji zvinodiwa zvemidziyo. Inoda kuve nehunyanzvi hwechigadzirwa tekinoroji, ruzivo rweprojekiti, uye zano rekugadzirisa matanho kumamiriro enzvimbo kuti ive nechokwadi chekuti tsvina yemhando yepamusoro yemidziyo yekuchenesa mvura inosangana neyakajairwa. Jiading kuchengetedzwa kwezvakatipoteredza ifekitari yepamusoro muindasitiri yekuchenesa tsvina kwemakore gumi, yakavakirwa mudunhu reJiangsu, mwaranzi kune nyika yese, yakatarisana nemhiri kwemakungwa, ine yakasimba chigadzirwa tekinoroji yemhando yekudzora timu.
