Malo otayirapo zinyalala ku Changshengqiao ndi malo otayirako zinyalala ngati chigwa ndipo malo ake ndi 690,642 m. ³ , malo otayirapo nthaka pafupifupi 379,620 m ³ ndi kuthekera kopanga pafupifupi 14 miliyoni m ³ . Malo otayirako zinyalala adayikidwa kumapeto kwa Julayi 2003 ndipo adatsekedwa kumapeto kwa 2016. Yakhala ikutsekedwa ndi kukonzanso kuyambira 2018.

Malo opangira chithandizo cha leachate omwe alipo ku Changshengqiao Landfill adapangidwa ngati malo okwana 1,730 ton/d, opangidwa ndi 400 ton/d MBR+DTRO system ndi 1,330 ton/d STRO chithandizo chadzidzidzi. Pakalipano, machitidwe a MBR + DTRO amatulutsa pafupifupi matani 100 a leachate concentrate patsiku, ndipo malo a STRO amatulutsa pafupifupi matani 400 a concentrate patsiku. Zomwe zimapangidwa ndi leachate zimasakanizidwa ndikusungidwa mu dziwe lolingana mkati mwa malo otayirako, omwe pafupifupi 38,000 m. ³ amasungidwa mkati motayiramo ndi pafupifupi 140,000 m ³ amasungidwa kunja kwa dothi. Malo osungiramo malowa atsala pang'ono kudzaza, ndi zoopsa za chilengedwe.

Dongosolo la chithandizo chamankhwala cha leachate mu pulojekitiyi makamaka limapangidwa ndi magawo awiri, imodzi ndi MBR + DTRO yokhazikika ndi chithandizo chamankhwala chamankhwala apamwamba kwambiri, ndipo inayo ndi STRO yokhazikika popanda chithandizo chamankhwala amthupi. Ubwino wamadzi wazinthu ziwirizi umasiyana kwambiri, ndipo chinthu chochizira cha polojekitiyi ndi chosakanikirana.

Malizitsani mankhwala a leachate ndende mu zotayiramo mkati 3 miyezi ntchito boma.

Malizitsani ndende ya leachate mkati ndi kunja kwa malo otayirapo mkati mwa miyezi 18 yogwira ntchito.

Zochita za leachate zatsopano zimakhazikika nthawi imodzi tsiku lililonse.

Malinga ndi lipoti laubwino wamadzi lamadzi am'madzi komanso zomwe kampani yathu idakumana nayo pama projekiti ofanana, kapangidwe ka madzi a projekitiyi ndi motere:

ZLD 1,000 m³/d njira yothandizira
Pretreatment + Concentration + Evaporation + Desiccation

Kukhazikika mu thanki yofananira kumakhala ndi zolimba zoyimitsidwa (SS) komanso zimakhala zolimba kwambiri. Onse a iwo ayenera kuchotsedwa mwa kufewetsa ndi pretreatment TUF.

Utsi wochokera ku kufewetsa umathandizidwa ndi nembanemba ya zinthu. Kusankhidwa kwa membrane wakuthupi kumadalira kulemera koyenera kwa maselo. Malingana ndi zotsatira zoyesera, kulemera kwa maselo oyenera kungaganizidwe. Pankhaniyi, mbali ya colloid ndi macromolecular zinthu organic akhoza kusankha kukanidwa ndi osankhidwa nembanemba zinthu popanda kukana kuuma ndi mchere. Izi zitha kupereka malo abwino ochitira HPRO ndi MVR. Komanso, dongosolo amatha 90-98 % kuchira ndi otsika kuthamanga ntchito chifukwa cha zinthu nembanemba makhalidwe. Kuonjezera apo, pang'onopang'ono kuika maganizo kumathandizidwanso ndi desiccation.

Madzi osefukira a memtrane amapangidwa ndi HPRO. Popeza HPRO idatengera gawo la anti-pollution disc membrane, imatha kuyika kwambiri madzi osaphika, ndikuchepetsa kuchuluka kwa madzi otuluka. Chifukwa chake, ndalama zonse zogulira ndikugwiritsa ntchito zitha kupulumutsidwa.

Mawonekedwe a permeate kuchokera ku nembanemba yazinthu ndiabwino kuchepetsa kuchuluka kwa anti-foam wothandizira omwe amagwiritsidwa ntchito mumchitidwe wa evaporation wa MVR. Zimenezi zingathe kuthetsa thobvu chodabwitsa. Kuonjezera apo, mchere sungakhoze kukulungidwa ndi zinthu zamoyo, zomwe zimakhala zopindulitsa kwa khola lokhazikika komanso losalekeza la evaporation crystallization. Komanso, popeza MVR dongosolo akhoza ntchito zinthu acidic ndi mavuto zoipa ndi kutentha otsika, ndi makulitsidwe ndi dzimbiri chodabwitsa angapewedwe. Komanso, chithovucho chimakhala chovuta kupanga, zomwe zimapangitsa kuti pakhale mpweya wabwino wa condensate. The MVR permeate imayenda kubwerera ku nembanemba dongosolo kuti akalandire chithandizo asanatulutsidwe. Madzi ochokera ku MVR amathandizidwa ndi desiccation.

Pali mitundu itatu ya zinyalala zomwe zimapangidwa mu projekiti iyi, zomwe ziyenera kukonzedwa. Ndiwo matope opangidwa ndi pretreatment, matope a brine kuchokera ku evaporation crystallization ndi matope ochokera ku desiccation.

Mgwirizanowu udasainidwa mu Novembala, 2020. Zida zokhala ndi 1000 m³/d mphamvu yakuchiritsa zidayikidwa ndikuvomerezedwa mu Epulo, 2020. Ntchito ya Jiarong Changshengqiao concentration ZLD imatha kuonedwa ngati chizindikiro chamakampani a WWT.
