Zvipembenene zvausingaone zvave kuita simba idzva mukuchenesa tsvina

Kushandisa tekinoroji yemicrobial kurapa tsvina yemumaguta nekumaruwa ine simba rakaderera, kugona kwakanyanya, diki diki remarara, mashandiro ari nyore uye manejimendi, uye inogona zvakare kuwana phosphorus kupora uye kudzokorodza kwemvura yakacheneswa. Parizvino, tekinoroji yehutachiona yakawedzera zvishoma nezvishoma kuita nzira inoshanda yekugadzirisa matambudziko akakosha ezvakatipoteredza akadai sekusvibiswa kwemvura.

Mvura chinhu chakakosha chinodiwa pakusimudzira budiriro yenharaunda. Nekuvandudzwa kwemaguta uye kufambira mberi kwemaindasitiri, zvinosvibisa zvakawanda uye zvakaoma kubvisa zvinopinda munzvimbo yemvura yakasikwa, zvichikanganisa kunaka kwemvura uye pakupedzisira kuisa hutano hwevanhu pangozi.

Kuitwa kwenguva refu kwakaratidza kuti nzira dzechinyakare dzekuchenesa tsvina hadzigone kuzadzisa zvinodiwa zvekubvisa zvezvinosvibisa mvura zviripo, saka kutsvagisa nekuvandudzwa kwehunyanzvi hwekurapa hutsva uye hunoshanda ndiro basa guru razvino.

Microbial treatment tekinoroji yakwezva kutarisisa kwenyanzvi dzakawanda kumba nekune dzimwe nyika nekuda kwezvakanaka zvayo seyakanaka inosvibisa maitiro ekurapa, kuwedzera kupfumisa mwero wematambudziko makuru, chiitiko chepamusoro chehutachiona, kuramba kwakasimba kukanganiswa kwezvakatipoteredza, mutengo wakaderera wehupfumi uye kushandiswazve. Nekuvandudzwa kwetekinoroji, ma microorganisms anogona "kudya kusvibiswa" zvishoma nezvishoma akashandiswa zvakanyanya mumunda wekuchenesa tsvina.

Microbial tekinoroji ine zvakanakira zviri pachena mukurapa tsvina yemudhorobha neyekumaruwa

Kusvibiswa kwemvura kunowanzoreva kuparara kwemhando yemvura uye kudzikiswa kwekoshe yekushandiswa kwemvura kunokonzerwa nezvikonzero zvevanhu. Zvikuru zvinosvibisa zvinosanganisira tsvina yakasimba, aerobic organic matter, refractory organic matter, heavy metals, chirimwa chekudya, asidhi, alkali uye petroleum zvinhu nezvimwe makemikari zvinhu.

Parizvino, kurapwa kwetsvina kwechinyakare kungave kuparadzanisa zvinosvibisa zvisinganyungudika kuburikidza nemaitiro emuviri senge gravity sedimentation, coagulation clarification, buoyancy, centrifugal separation, magnetic separation, kana kushandura zvinosvibisa nenzira dzemakemikari senge acid-base neutralization, kunaya kwemakemikari, oxidation-kuderedza, nezvimwe. . Mukuwedzera, zvinosvibisa zvakanyungudutswa mumvura zvinogona kuparadzaniswa nekushandisa adsorption, ion exchange, membrane separation, evaporation, freezing, nezvimwewo.

Nekudaro, pakati peidzi nzira dzechinyakare, zvidyarwa zvekurapa zvinoshandisa nzira dzemuviri dzekuchenesa tsvina zvinowanzogara munzvimbo yakakura, zvine hupfumi hwepamusoro uye mutengo wekushandisa, kushandiswa kwesimba kwakanyanya, manejimendi akaomarara, uye anowanzoita sludge kuzvimba. Midziyo haigone kusangana nezvinodiwa zvekushanda kwepamusoro uye kushandiswa kwakaderera; nzira dzemakemikari dzine mari yekushanda yakakwira, dzinodya huwandu hwemakemikari reagents, uye dzinowanzoita kusvibiswa kwechipiri.

Kushandisa tekinoroji yemicrobial kurapa tsvina yemumaguta nekumaruwa ine simba rakaderera, kugona kwakanyanya, diki diki remarara, mashandiro ari nyore uye manejimendi, uye inogona zvakare kuwana phosphorus kupora uye kudzokorodza kwemvura yakacheneswa. Wang Meixia, mudzidzisi paInner Mongolia Baotou Light Indasitiri Vocational uye Technical College uyo ave kwenguva yakareba achiita bioengineering uye tsvakurudzo yekutonga kwezvakatipoteredza, akati teknolojia yehutachiona yakagadziridzwa zvishoma nezvishoma ikava nzira inoshanda yekugadzirisa matambudziko akakurumbira ezvakatipoteredza akaita semvura. kusvibiswa.

Tudiki madiki anowana zvishamiso mu "kurwa kunoshanda"

Mugore Idzva reGore reTiger, kujeka mushure mechando muCaohai, Weining, Guizhou. Mazana emakoroni ane mitsipa mitema anotamba zvinoyevedza padhamu. Mapoka egrey geese dzimwe nguva anokwira pasi uye dzimwe nguva anotamba mumvura. Egrets anomhanya nekuvhima pamahombekombe, achikwezva vanopfuura-nekuti vamire. Tarisa, tora mafoto nemavhidhiyo. Weining Caohai inzvimbo yakajairwa yemvura yakachena dhamu uye dziva rakakura kwazvo remvura yakachena muGuizhou. Mumakumi mashoma emakore apfuura, nekuwedzera kwehuwandu hwevanhu uye kazhinji zviitiko zvevanhu, Weining Caohai yaimbova padanho rekunyangarika, uye muviri wemvura wakava eutrophic.

Chikwata chinotungamirwa naZhou Shaoqi, Mutevedzeri weMutungamiriri weGuizhou University, chakakunda matambudziko akareba-asingakundiki mumunda wekutsvagisa biological denitrification munyika, uye neunyanzvi akashandisa tekinoroji yekudzivirira hutachiona kupa Caohai hupenyu hutsva. Panguva imwecheteyo, timu yaZhou Shaoqi yakasimudzirawo kushandiswa kwetekinoroji nyowani nehuinjiniya kuminda yetsvina yemumaguta, mafuta ekunatsa tsvina, marara emarara uye tsvina yekumaruwa, uye vakawana mhedzisiro inoshamisa mukudzora kusvibiswa.

Muna 2016, miviri yemvura yakasviba uye inonhuwa yeXiaohe neLeifeng Rivers muChangsha High-tech Zone yakakwezva kutsoropodza. Hunan Sanyou Environmental Protection Technology Co., Ltd. yakashandisa mvura microbial activation system kubvisa dambudziko dema uye hwema muRwizi rwaXiaohe mumwedzi mumwe chete nehafu, zvichiita kuti tekinoroji yehutachiona ive mukurumbira. "Nekuita kuti hutachiona hwemvura hushande uye kuita kuti hurambe huchiwanda, tinoronga patsva, tinovandudza nekugadzirisa hutachiona hwemvura uye kudzorera kugona kuzvichenura kwemuviri wemvura," akadaro Dr. Yi Jing wekambani.

Sezvineiwo, muWest Lake Garden yeChanghai New Village, Yangpu District, Shanghai, mudziva rakafukidzwa nealgae hombe yebhuruu, mvura ine tsvina yakasvibira yakasvibirira yakashanduka kuita rukova rwakajeka rwekuti hove dzishambire mariri, uye mhando yemvura yegungwa zvakare. yakachinja kubva pakuipisisa kupfuura Chikamu 5 kuenda kuChikamu 2 kana 3. Chakagadzira chishamiso ichi yaive tekinoroji yekuvandudza yakagadziridzwa neEnvironmental New Technology Team yeTongji University - iyo mvura microbial activation system. Iyi tekinoroji yakashandiswa zvakare ku300,000-square-metres Haidong Wetland ecological restoration uye kuchenesa chirongwa pamhenderekedzo yekumabvazuva yeDianchi Lake muYunnan.

Muna 2024, nyika yangu yakaparura mitemo yakati wandei ine chekuita nekucheneswa kwesuweji kusimudzira kushandiswa kwetsvina. Hwaro hwegore negore hwekuchenesa tsvina hwakawedzerwa, uye mari yekuchenesa tsvina yeindasitiri yakawedzera. Parizvino, neshanduko yebudiriro yesainzi uye tekinoroji uye nekukwira kweakawanda emakambani ekuchengetedza nharaunda ekuchengetedza nharaunda, hutachiona hwehutachiona huchashandiswa zvakanyanya munzvimbo dzakasiyana siyana sekuvaka, kurima, zvekufambisa, simba, petrochemicals, kuchengetedza kwezvakatipoteredza, maguta. landscape, medical catering, etc.
