Kuyambira pomwe idakhazikitsidwa, Liancheng Environmental Company yakhala ikutsatira kwambiri malingaliro ogulitsa okhudza makasitomala komanso cholinga chawo chachikulu, ndipo kudzera mu machitidwe a nthawi yayitali a maphwando ambiri monga maziko, pali anthu otanganidwa a "Liancheng" m'malo opanga mainjiniya mdziko lonselo. Kumayambiriro kwa Meyi, bungwe loyesa ku Hubei lidapereka lipoti loyesa pa chitsanzo cha madzi chomwe chidaperekedwa ndi Hubei Lomon Phosphorus Chemical Co., Ltd. Lipotilo lidawonetsa kuti kuchuluka kwa zinthu zolimba (SS) zomwe zidasungidwa mu chitsanzo cha madzi choyesedwa chinali 16 mg/L, ndipo kuchuluka kwa phosphorous (TP) konse kunali 16 mg/L. ndi 0.02mg/L, ndipo kuchuluka kwa chinyezi cha matope ochotsedwa madzi ndi 73.82%. Malinga ndi zotsatira za mayeso, zatsimikiziridwa kuti zida zochizira madzi za LCCHN-5000 zomwe zimapangidwa ndikuperekedwa ndi kampani yathu ya Hubei Lomon Phosphorus Chemical Co., Ltd. ndizoyenerera pakupanga ndi kugwiritsa ntchito, kupitirira kwambiri zizindikiro zomwe makasitomala amafunikira. Ubwino wa zidazi ndi wokhutiritsa kwambiri, ndipo zimasonyezanso kuti zida zophatikizika za Liancheng magnetic coagulation treatment process integrated zili ndi pulojekiti yoyamba ya chitsanzo kudera la Hubei.
Madzi osaphika ndi zizindikiro za makasitomala oyeretsedwa komanso kuyerekeza zotsatira zenizeni
Kumayambiriro kwa Seputembala 2021, atalandira zofunikira zaukadaulo zomwe kasitomala adapereka, Manager Qian Congbiao wa Dipatimenti Yachiwiri ya Liancheng Environmental Sewage adapanga dongosolo loyamba la zida zochizira zosakaniza za flocculation + sedimentation + kusefa, koma chifukwa cha mikhalidwe yapadera yogwirira ntchito pamalopo, Kukula kwa zida zomwe zidapangidwa poyamba sikunakwaniritse zofunikira pa zomangamanga. Atalankhulana ndi kasitomala, Manager Tang Lihui wa Dipatimenti ya Wastewater Department adaganiza za dongosolo laukadaulo lochizira madzi otayika pogwiritsa ntchito maginito coagulation. Chifukwa cha kusowa kwa nthawi, ogwira ntchito zaukadaulo ku likulu sakanatha kupezeka pakusinthana kwaukadaulo. Ofesi yathu idalumikizana ndi kasitomala kuti atsimikizire, ndipo adachita kusinthana kwaukadaulo kwakutali kudzera mu netiweki. Pambuyo poyambitsa mwatsatanetsatane dongosolo la kampani yathu ndi Manager Tang, kasitomala adavomereza mogwirizana ndipo pamapeto pake adatsimikiza kuti 5000. Pulojekiti yochizira madzi otayika ya phosphate rock ya tani / tsiku imagwiritsa ntchito zida zochizira madzi zophatikizana zamaginito, zomwe ndi zazitali mamita 14.5, m'lifupi mamita 3.5 ndi kutalika mamita 3.3.
Zipangizozi ndi zosavuta kuziyika komanso zosavuta kugwiritsa ntchito. Titafika pamalo a polojekitiyi pa 13 Marichi, ntchito yoyambitsa madzi ndi magetsi inayamba pa 16 Marichi. Patatha masiku awiri, zidazo zafika pamlingo wokhazikika wokha popanda kuyang'aniridwa, ndipo magawo ogwirira ntchito a zidazo akhoza kusinthidwa ndikuyikidwa patali kudzera pa nsanja yanzeru. Pali nsanja yowunikira makanema yotumizira momwe zinthu zikuyendera mchipinda cha zida, kenako imatumizidwa kuchokera ku mafoni am'manja, makompyuta ndi zida zina zambiri. Pambuyo pa tsiku logwira ntchito zokha, kuyesa koyambirira kwa mtundu wa madzi otuluka m'zidazo kwafika pamlingo woyenera m'mawa wa 19, kuyembekezera kuvomerezedwa komaliza kwa ntchitoyi.
Kudzera mu kutsatira ndi kumvetsetsa njira yogulitsira isanayambe, yogulitsira komanso yomaliza kugulitsa, titha kumvetsetsa kuti njira yothirira madzi ya Liancheng integrated magnetic coagulation ili ndi mawonekedwe ophatikiza zida, kuphatikiza nzeru ndi nzeru, ndipo kukhazikitsa ndi kukonza zida sikukhudzidwa ndi nyengo monga kutentha. , yoyenera malo osiyanasiyana, ndalama zazing'ono zaukadaulo wa zomangamanga komanso nthawi yochepa yomanga, kukhazikitsa ndi kuyambitsa zida mwachangu, malo ochepa ndi zina zambiri.
Chiyambi cha ndondomeko：
Ukadaulo wa maginito wothira mpweya (high-efficiency precipitation) ndi kuwonjezera ufa wa maginito womwe uli ndi mphamvu yokoka ya 4.8-5.1 mu njira yachikhalidwe yothira mpweya, kuti uphatikizidwe ndi kuthira kwa zinthu zoipitsa, kuti ulimbikitse mphamvu ya kuthira mpweya ndi kuthira mpweya, kotero kuti thupi lopangidwa ndi violet likhale lolimba komanso lamphamvu, kuti likwaniritse cholinga cha kutayira mpweya mwachangu. Liwiro lokhazikika la maginito flocs likhoza kukhala lalikulu mpaka 40m/h kapena kuposerapo. Ufa wa maginito umabwezeretsedwanso kudzera mu makina odula kwambiri komanso olekanitsa maginito.
Nthawi yokhalamo ya ndondomeko yonseyi ndi yochepa kwambiri, kotero pa zinthu zambiri zoipitsa kuphatikizapo TP, mwayi woti njira yotsutsana ndi kusungunuka ndi wochepa kwambiri. Kuphatikiza apo, ufa wa maginito ndi flocculant zomwe zimawonjezeredwa mu dongosololi ndizoopsa kwa mabakiteriya, mavairasi, mafuta ndi tinthu tating'onoting'ono tating'onoting'ono. Ili ndi mphamvu yabwino yoyamwa, kotero zotsatira za kuchotsa kwa mtundu uwu wa zoipitsa ndi zabwino kuposa za njira yachikhalidwe, makamaka kuchotsa phosphorous ndi zotsatira za kuchotsa SS ndizofunikira kwambiri. Ukadaulo wa maginito wa flocculation (high-efficiency precipitation) umagwiritsa ntchito ufa wa maginito wakunja kuti uwonjezere mphamvu ya flocculation ndikuwonjezera mphamvu ya mvula. Nthawi yomweyo, chifukwa cha mphamvu yake yachangu ya mvula, ili ndi zabwino zambiri monga liwiro lalikulu, mphamvu yayikulu komanso malo ochepa poyerekeza ndi njira zachikhalidwe.
Mawonekedwe：
1. Liwiro la kukhazikika ndi lachangu, lomwe lingafikire liwiro lalikulu la kukhazikika la 40m/h;
2. Kulemera kwakukulu pamwamba, mpaka 20m³/㎡h~40m³/㎡h;
3. Nthawi yokhalamo ndi yochepa, yochepera mphindi 20 kuchokera pamene madzi alowa m'malo otulukira madzi kupita pamene madzi atuluka (nthawi zina, nthawi yokhalamo ikhoza kukhala yochepa);
4. Kuchepetsa bwino malo a pansi, ndipo malo a pansi pa thanki yosungira madzi akhoza kukhala ochepa ngati 1/20 ya njira yachizolowezi;
5. Kuchotsa phosphorous moyenera, TP yabwino kwambiri yotulutsa madzi ingakhale yotsika kufika pa 0.05mg/L;
6. Madzi owonekera bwino, kutayirira <1NTU;
7. Kuchuluka kwa SS komwe kumachotsedwa ndi kwakukulu, ndipo madzi otayira abwino kwambiri ndi ochepera 2mg/L;
8. Kubwezeretsanso ufa wa maginito, kuchuluka kwa kubwezeretsanso ndi kopitilira 99, ndipo mtengo wogwirira ntchito ndi wotsika;
9. Konzani bwino mlingo wa mankhwala, chepetsani ndalama zogwirira ntchito, ndikusunga 15% ya mlingo ngati kuli koyenera;
10. Dongosololi ndi laling'ono (lingathenso kupangidwa kukhala chipangizo chogwiritsira ntchito pafoni), chomwe chingathe kulamulira zokha ndipo n'chosavuta kugwiritsa ntchito.
Ukadaulo wa maginito wothira madzi ndi ukadaulo watsopano wosintha. Kale, ukadaulo wa maginito wothira madzi sunkagwiritsidwa ntchito kawirikawiri m'mapulojekiti ochizira madzi, chifukwa vuto la kuchira kwa ufa wa maginito silinathetsedwe bwino. Tsopano vutoli laukadaulo lathetsedwa bwino. Mphamvu ya maginito ya separator yathu ya maginito ndi 5000GS, yomwe ndi yamphamvu kwambiri ku China ndipo yafika paukadaulo wapamwamba padziko lonse lapansi. Kuchuluka kwa kuchira kwa ufa wa maginito kumatha kufika pa 99%. Chifukwa chake, ubwino waukadaulo ndi zachuma wa njira yothira madzi ya maginito wothira madzi umaonekera bwino. Njira yothira madzi ya maginito imagwiritsidwa ntchito kwambiri kunyumba ndi kunja pochizira zimbudzi za m'mizinda, kugwiritsanso ntchito madzi obwezeretsedwanso, kuchiza madzi akuda ndi onunkhira m'mitsinje, kuchiza madzi otayidwa okhala ndi phosphorous yambiri, kuchiza madzi otayidwa pogwiritsa ntchito mapepala, kuchiza madzi otayidwa m'minda yamafuta, kuchiza madzi otayidwa m'migodi ndi madera ena.
