Nekukurumidza kusimudzira kwemaindasitiri uye kugariswa kwemadhorobha, yakanyanya kuwanda mvura yetsvina yave dambudziko rakakura rezvakatipoteredza. High-concentration wastewater haingori nenhamba yakawanda yeorganic matter, inorganic substances, heavy metals nezvimwe zvinokuvadza, uye concentration yayo inopfuura nekure dhizaini yezvakajairwa zvivakwa zvekuchenesa mvura. Nokudaro, kushandiswa kwemvura yakasvibiswa kwepamusoro-yepamusoro uye kubuda kunonyanya kukosha.
1. Tsanangudzo uye maitiro emvura yakanyanyisa yakasvibiswa
Kuwanda kwemvura yetsvina, kazhinji inoreva mvura yetsvina ine huwandu hwakanyanya hwezvinhu zvipenyu, simbi inorema, zvinhu zvine chepfu uye zvine njodzi nezvimwe zvinosvibisa. Zviri mukati mezvinosvibisa mumvura yetsvina zvinodarika zvemvura yakasviba zvakajairika uye zvakaoma kurapa. Inogona kunge iine marudzi mazhinji akasiyana ezvinosvibisa, senge organics, heavy metals, uye radioactive zvinhu. Zvimwe zvezvinosvibisa zvinogona kuve ne inhibitory mhedzisiro pazvipembenene, zvichikanganisa maitiro ekurapwa kwebiology, uye zvinonetsa kubviswa nenzira dzakajairwa dzebhayoloji kurapwa.
2. Mamiriro ezvinhu ekugadzirwa kwemvura yakasviba yakakwira
Kugadzirwa kweKemikari: Mvura yakasviba inogadzirwa panguva yekugadzirwa kwemakemikari inowanzove ine huwandu hukuru hwezvinhu zvehupenyu, simbi inorema uye zvimwe zvinosvibisa.
Indasitiri yemishonga: Mvura yetsvina yemishonga inowanzove neyakawandisisa yeorganic matter, antibiotics, nezvimwewo, uye inonetsa kurapa.
Indasitiri yeDyestuff uye machira: Mvura yakasviba inogadzirwa kubva kumaindasitiri aya kazhinji ine huwandu hukuru hwekuomesesa kushatisa organics uye chromaticity.
Electroplating uye metallurgy: maitiro e electroplating uye simbi inoburitsa tsvina ine simbi inorema uye chepfu zvinhu.
3. Iyo yakakosha tekinoroji yemhando yepamusoro yekuchenesa sewage treatment plant
High concentration yetsvina yekuchenesa chirimwa, kazhinji kuburikidza nemuviri kana kemikari nzira dzekubvisa zvimedu zvakakura mumvura yetsvina, yakamiswa yakasimba, nezvimwewo, kugadzira mamiriro ekuzotevera kurapwa. Ichave zvakare kuburikidza neakadai seFenton oxidation, ozone oxidation uye imwe yepamusoro oxidation tekinoroji, kuburikidza nekugadzirwa kweakasimba oxidants kuchave kwakaoma kushatisa organic zvinhu muzvinhu zvinoora zviri nyore. Iyo metabolism ye microorganisms inoshandiswa kubvisa organic zvinhu kubva mumvura ine tsvina. Kumvura yakasviba yakanyanyisa, musanganiswa wemaitiro akadai seanaerobic uye aerobic inogona kushandiswa kugadzirisa kurapwa. Zvinhu zvakanyungudutswa mumvura yetsvina zvinogona zvakare kubviswa nemaitiro emuviri kuburikidza ne membrane kupatsanura matekiniki akadai se ultrafiltration uye reverse osmosis. Heavy metal kurapwa matekinoroji akadai sekunaya kwemakemikari, ion exchange uye adsorption anoshandiswa kubvisa heavy metal ions kubva mumvura ine tsvina.
Naizvozvo, kune yakanyanya kuwanda kweiyo tsvina yekuchenesa chirimwa, kuve nechokwadi chekuti tsvina inosangana neyakajairwa, sarudzo ine musoro yekurapa maitiro, kudzora kwakasimba kwemaitiro ekurapa, kusimbisa pre-kurapwa, optimize maparamita ekushanda pamwe nekuyedza nguva nenguva uye. kuongorora kunokosha zvikuru, kana matambudziko akawanikwa, tora matanho panguva yekugadzirisa.
Yepamusoro yekuchenesa sewage yekuchenesa nekuda kwehunhu hwayo hwemhando yemvura, nekuti iyo midziyo ine yakasimba tekinoroji zvinodiwa, kudiwa kwekuve yakanaka chigadzirwa tekinoroji, ruzivo rweprojekiti, pamwe nepfungwa yemamiriro enzvimbo, kuitira kuti ive nechokwadi chekuti yakakwirira. kusangana kwemidziyo yekuchenesa mvura yetsvina kuti isangane nezviyero zvetsvina. Liding Environmental Dziviriro ifekitari yemakore gumi muindasitiri yekuchenesa mvura yetsvina, yakavakirwa muJiangsu, inopenya nenyika yese, yakatarisana nemhiri kwemakungwa, ine yakasimba chigadzirwa tekinoroji yekudzora mhando.
