Kubva payakavambwa, Liancheng Environmental Company yakaramba ichitevedzera pfungwa dzekutengesa dzekuti vatengi vatarisire uye vatarisire basa ravo, uye kuburikidza nekushanda kwenguva refu kwemapato akawanda senheyo, kune vanhu vakabatikana ve "Liancheng" munzvimbo dzeinjiniya munyika yese. Pakutanga kwaChivabvu, kambani yekuedza muHubei yakaburitsa mushumo wekuyedza pamusoro pemvura yakatumirwa neHubei Lomon Phosphorus Chemical Co., Ltd. Mushumo wacho wakaratidza kuti huwandu hwezvinhu zvakamiswa (SS) mumuenzaniso wemvura wakaedzwa hwaive 16 mg/L, uye huwandu hwese hwephosphorus (TP) hwaive 16 mg/L. i0.02mg/L, uye huwandu hwehunyoro hwetsvina yakabviswa mvura hwaive 73.82%. Zvichienderana nemhedzisiro yebvunzo, zvakaonekwa kuti michina yekurapa mvura yeLCCHN-5000 yakagadzirwa uye yakapihwa nekambani yedu yeHubei Lomon Phosphorus Chemical Co., Ltd. inokodzera mukugadzira nekushanda, ichipfuura zviratidzo zvinodiwa nevatengi. Hunhu hwechitarisiko chemidziyo iyi hunogutsa zvikuru, uye zvinoratidzawo kuti michina yakabatanidzwa yeLiancheng magnetic coagulation treatment process ine purojekiti yekutanga yemuenzaniso munharaunda yeHubei.
Mvura isina kubikwa uye zviratidzo zvevatengi vakagadziriswa uye kuenzanisa mhedzisiro chaiyo
Pakutanga kwaGunyana 2021, mushure mekugashira zvinodiwa zvehunyanzvi zvakapihwa nemutengi, Maneja Qian Congbiao weDhipatimendi reChipiri reLiancheng Environmental Sewage akatanga aronga michina yekurapa yakabatana ye flocculation + sedimentation + filtration process, asi nekuda kwemamiriro ekushanda akakosha panzvimbo iyi, saizi yemidziyo yakagadzirwa pakutanga haina kukwanisa kusangana nemamiriro ekuvaka ehurumende. Mushure mekutaurirana nemutengi, Maneja Tang Lihui weDhipatimendi reWastewater akasarudza hurongwa hwehunyanzvi hwekurapa mvura yakasviba ne magnetic coagulation. Nekuda kwekushomeka kwenguva, vashandi vehunyanzvi vehofisi huru havana kukwanisa kuvapo pakuchinjana kwehunyanzvi. Hofisi yedu yakabata mutengi kuti isimbise, uye yakaita kushandurana kwehunyanzvi kuri kure kuburikidza ne network conference mode. Mushure mekuunzwa kwakadzama kwechirongwa chekambani yedu naManeja Tang, chakazivikanwa nemutengi uye pakupedzisira chakagadzwa kuti 5000. Chirongwa chekurapa mvura yakasviba che ton/day phosphate rock chinoshandisa seti yemidziyo yekurapa mvura yakabatana ye magnetic coagulation, ine kureba kwe 14.5m, upamhi hwe 3.5m uye 3.3m.
Midziyo iyi iri nyore kuisa uye iri nyore kushandisa. Mushure mekusvika panzvimbo yepurojekiti musi wa13 Kurume, kutanga kushanda kwemvura nemagetsi kwakatanga musi wa16 Kurume. Mazuva maviri gare gare, michina yasvika pakushanda kwayo yoga pasina anoitarisira, uye maparameter ekushanda kwemidziyo anogona kugadziriswa uye kuiswa kure kuburikidza nepuratifomu yakangwara. Kune puratifomu yekutarisa vhidhiyo yekushanda mukamuri yemidziyo, uye inotumirwa kubva kumafoni, makomputa nezvimwe zvakawanda. Mushure mezuva rekushanda otomatiki, kuyedzwa kwekutanga kwehunhu hwemvura yetsvina yemidziyo kwasvika padanho remangwanani emusi wa19, kuchimirira kugamuchirwa kwekupedzisira kwepurojekiti.
Kuburikidza nekutevera nekunzwisisa maitiro epurojekiti isati yatengeswa, iri kutengeswa uye mushure mekutengeswa, tinogona kunzwisisa zvechokwadi kuti kurapwa kwemvura kweLiancheng integrated magnetic coagulation kune hunhu hwekubatanidza michina, kubatanidza njere nehungwaru, uye kuiswa uye kugadzirisa michina hazvikanganisirwe nemamiriro ekunze akadai sekupisa. , yakakodzera nzvimbo dzakasiyana-siyana, mari diki yeinjiniya yezvivakwa uye nguva pfupi yekuvaka, kuiswa nekukurumidza kwemidziyo nekuiswa, nzvimbo diki yekufamba uye zvimwe zvinhu zvakawanda.
Sumo yemaitiro：
Tekinoroji yekubvisa mvura ine magnetic coagulation (high-efficiency precipitation) ndeyekuwedzera panguva imwe chete magnetic powder ine giravhiti chaiyo ye4.8-5.1 mumaitiro echinyakare e coagulation ne precipitation, kuitira kuti ibatanidzwe ne flocculation yezvinosvibisa, kuitira kuti kusimbisa mhedzisiro ye coagulation ne flocculation, kuitira kuti muviri we violet uve wakasimba uye wakasimba, kuitira kuti chinangwa che high-speed sedimentation chisvike. Kumhanya kwekugadzikana kwe magnetic flocs kunogona kusvika 40m/h kana kupfuura. Magnetic powder inodzokororwazve kuburikidza nemuchina we high shear uye magnetic separator.
Nguva yekugara kwemaitiro ese ipfupi kwazvo, saka kune akawanda matsvina anosanganisira TP, mukana wekuti matsvina anyungudike ushoma kwazvo. Pamusoro pezvo, upfu hwemagineti neflocculant zvinowedzerwa musystem zvinokuvadza mabhakitiriya, mavhairasi, mafuta nezvimwe zvidiki zvakasiyana-siyana. Ine adsorption effect yakanaka, saka kubvisa kwemhando iyi yetsvina kuri nani pane kwemaitiro echinyakare, kunyanya kubviswa kwephosphorus uye SS effects zvakakosha zvikuru. Magnetic coagulation flocculation (high-efficiency precipitation) tekinoroji inoshandisa external magnetic powder kuwedzera flocculation effect uye kuvandudza precipitation effect. Panguva imwe chete, nekuda kwekushanda kwayo nekukurumidza kwemvura, ine mabhenefiti akawanda akadai sekumhanya kwakanyanya, kushanda kwakanyanya uye small footprint zvichienzaniswa nemaitiro echinyakare.
Zvinhu zvirimo：
1. Kumhanya kwekugadzirisa zvinhu kunokurumidza, uko kunogona kusvika kumhanya kwakanyanya kwe40m/awa;
2. Mutoro wepamusoro, kusvika 20m³/㎡h~40m³/㎡h;
3. Nguva yekugara ipfupi, inosvika maminetsi makumi maviri kubva pakupinda kwemvura kusvika pakubuda kwemvura (mune dzimwe nguva, nguva yekugara inogona kupfupika);
4. Kuderedza nzvimbo yepasi zvinobudirira, uye nzvimbo yepasi yetangi remvura inogona kuderera kusvika 1/20 yemaitiro enguva dzose;
5. Kubvisa phosphorus zvakanaka, TP yakanaka inogona kuva yakaderera kusvika ku0.05mg/L;
6. Kujeka kwemvura kwakanyanya, kusviba <1NTU;
7. Mwero wekubviswa kweSS wakakwira, uye mvura yakanakisa inoyerera isingasviki 2mg/L;
8. Kudzokorodza hupfu hwemagineti, mwero wekudzokorodza unopfuura 99, uye mutengo wekushanda wakaderera;
9. Kunyatso gadzirisa mushonga wemishonga, kuderedza mari yekushandisa, uye kuchengetedza 15% yemushonga kana zvakanakisa;
10. Sisitimu iyi idiki (inogonawo kugadzirwa kuita mudziyo wekugadzirisa nharembozha), iyo inogona kuita otomatiki uye iri nyore kushandisa.
Tekinoroji ye magnetic coagulation sedimentation tekinoroji itsva inochinja-chinja. Kare, tekinoroji ye magnetic coagulation sedimentation yaisawanzo shandiswa mumapurojekiti ekurapa mvura, nekuti dambudziko re magnetic powder recovery harina kugadziriswa zvakanaka. Iye zvino dambudziko iri re technical rakagadziriswa zvinobudirira. Simba re magnetic field re magnetic separator yedu i5000GS, iyo yakanyanya kusimba muChina uye yasvika patekinoroji inotungamira pasi rose. Mwero we magnetic powder recovery unogona kusvika kupfuura 99%. Saka, mabhenefiti e technical ne ehupfumi e magnetic coagulation precipitation process anonyatsoratidzwa. Magnetic coagulation process iri kushandiswa zvakanyanya kumba nekune dzimwe nyika pakurapa tsvina yemumaguta, kushandisazve mvura, kurapa mvura yemurwizi ine rima uye inonhuwa, phosphorus yakawanda Wastewater treatment, papermaking wastewater treatment, oilfield wastewater, mine wastewater treatment nedzimwe nzvimbo.
