Imyanda ya Changshengqiao ni ikibanza gisanzwe cyo guta imyanda gifite ubuso bwa 690,642 m ³ , ahantu hajugunywe imyanda igera kuri m 379.620 ³ n'ubushobozi bwo gushushanya hafi miliyoni 14 m ³ . Ikibanza cyo kumena imyanda cyatangiye gukoreshwa mu mpera za Nyakanga 2003 kikaba cyarafunzwe mu mpera za 2016. cyatangiye gufungwa no gusanwa kuva mu 2018.

Ikigo gisanzwe cyo kuvura imyanda i Changshengqiao Landfill cyakozwe nka toni 1,730 / d, kigizwe na toni 400 / d MBR + DTRO hamwe na toni 1,330 yo kuvura byihutirwa. Kugeza ubu, sisitemu ya MBR + DTRO itanga toni zigera kuri 100 za konsentrati ya leachate kumunsi, kandi ikigo cya STRO gitanga toni zigera kuri 400 kumunsi. Imyunyungugu ya leachate yakozwe ivangwa ikabikwa muri pisine iringaniye imbere y’imyanda, muri yo igera kuri 38.000 m ³ zibitswe imbere mu myanda hamwe na m 140.000 ³ bibitswe hanze y’imyanda. Ubushobozi bwo kubika urubuga buruzuye, hamwe nibibazo byangiza ibidukikije.

Sisitemu yo kuvura leachate yibanze muri uyu mushinga igizwe ahanini na konsentratif ebyiri, imwe ni MBR + DTRO yibanze hamwe nubuvuzi bwa biohimiki, naho ubundi ni STRO yibanze nta kuvura ibinyabuzima. Ubwiza bwamazi yibice byombi biratandukanye cyane, kandi ikintu cyo gutunganya uyu mushinga kivanze.

Kurangiza uburyo bwo kuvura imyanda mumyanda mugihe cyamezi 3 uhereye kubikorwa.

Kurangiza uburyo bwo kuvura imyanda imbere no hanze yimyanda mugihe cyamezi 18 uhereye kumikorere.

Gutunganya ibintu bishya byibanda icyarimwe kumunsi.

Dukurikije raporo y’amazi y’amazi y’icyitegererezo hamwe nuburambe bwikigo cyacu mumishinga isa, igishushanyo mbonera cyamazi meza yuyu mushinga ni aya akurikira:

ZLD 1.000 m³ / d uburyo bwo kuvura
Kwitegura + Kwibanda + Guhumeka + Kurandura

Kwibanda mu kigega cyo kuringaniza birimo ibintu byahagaritswe (SS) kandi bifite n'uburemere bukomeye. Byombi bigomba gukurwaho no koroshya no kwiyitirira TUF.

Amazi ava mu koroshya avurwa na membrane yibikoresho. Guhitamo ibintu biterwa nuburemere bukwiye. Ukurikije ibisubizo byubushakashatsi, uburemere bukwiye bwa molekile burashobora guhitamo. Muri iki gihe, igice cyibintu bya colloid na macromolecular birashobora kwangwa guhitamo ibintu byatoranijwe bitarinze gukomera nubunyu. Ibi birashobora gutanga ibidukikije byiza kubikorwa bya HPRO na MVR. Byongeye kandi, sisitemu ishoboye gukira 90-98% hamwe nigitutu cyo hasi bitewe nibintu biranga ibintu. Byongeye kandi, umubare muto wa concentrateur ukomeza kuvurwa na desiccation.

Amazi ava muri memtrane yibikoresho yibanze kuri HPRO. Kubera ko HPRO yakoresheje module irwanya umwanda, irashobora kwibanda cyane kumazi mbisi, bikagabanya ubwinshi bwamazi. Kubwibyo, muri rusange igishoro nigikorwa gishobora gukizwa.

Ubwiza bwa permeate buva mubintu nibyiza mugabanya kugabanya imiti irwanya ifuro ikoreshwa muri sisitemu ya MVR. Ibi birashobora gukuraho neza ibintu byinshi. Byongeye kandi, umunyu ntushobora gupfunyikwa ningingo ngengabuzima, ifitiye akamaro kristu ihindagurika kandi ikomeza. Uretse ibyo, kubera ko sisitemu ya MVR ishobora gukora mubihe bya acide hamwe numuvuduko mubi hamwe nubushyuhe buke, ibintu bishobora kwangirika no kwangirika. Nanone, ifuro iragoye kubyara, biganisha ku bwiza bwiza bwo guhumeka. MVR yinjira isubira muri sisitemu kugirango irusheho kuvurwa mbere yo gusohoka. Ubwonko buva muri MVR buvurwa na desiccation.

Hariho ubwoko butatu bwa silige bwakozwe muri uyu mushinga, bigomba kuvurwa. Nibisigazwa bya organic organique biva mubyitonderwa, umwanda wa brine uva kumyuka ya kristalisation hamwe nigitonyanga kiva mubutaka.

Amasezerano yashyizweho umukono mu Gushyingo 2020. Ibikoresho bifite 1000 m³ / d yo kuvura byashyizweho kandi byemerwa muri Mata, 2020. Umushinga wa ZLD wa Jiarong Changshengqiao wibanda ku nganda za WWT.
