Kafukufuku wa momwe madzi otayira amayeretsedwera m'makampani opanga nsomba zam'chitini

1, Mbiri ya Pulojekiti

Donghai Fisheries Co., Ltd., yomwe ili ku Peru, ndi kampani yamakono yopanga nsomba zam'chitini yokhala ndi mphamvu yopangira matani 10000 pachaka. Madzi otayira omwe amapangidwa panthawi yopanga amakhala ndi mawonekedwe wamba m'makampani: madzi otayira omwe amatuluka tsiku lililonse ndi pafupifupi matani 800, mafuta ochulukirapo ndi 350-400mg/L, opitilira miyezo yotulutsira, ndipo ilinso ndi mapuloteni ambiri, zinyalala za nsomba, ndi zinthu zotsalira zopangira. Kuchuluka kwa COD kuli pakati pa 2500-3000mg/L kwa nthawi yayitali. Njira yachikhalidwe ya "grid+air flotation+biochemistry" imatha kuchotsa zoipitsa zina, koma kugwira ntchito bwino kwa njira yosefera mphamvu ndi kochepa, ndipo chinyezi cha keke yosefera ndi chokwera mpaka 75%, zomwe sizimangopangitsa kuti mtengo wotsatira wa matope ukwere kwambiri, komanso kuchuluka kwa mafuta m'madzi otayira kumasinthasintha pakati pa 80-120mg/L, zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa miyezo yokhazikika.

2, Mavuto ndi Mayankho Ofunika Kwambiri

Mavuto pakugawa mafuta:

Mafuta omwe ali m'madzi otayira nsomba m'zitini amapezeka m'madzi osungunuka ndi osungunuka, ndipo njira zachikhalidwe zoyandama mumlengalenga zimakhala zovuta kuswa kwathunthu madzi osungunuka. Gulu la polojekitiyi likupereka njira yodziwira momwe mafuta osungunuka amagwirira ntchito.makina osindikizira odziyimira pawokha a chipinda cha hydraulic omwe amayendetsedwa ndi pulogalamu, yolumikizidwa ndi nsalu yosefera ya polypropylene yosagwira mafuta, kuti mafuta asungidwe kudzera mu kusefa kwa magawo atatu:

Gawo loyambirira la chithandizo:Madzi otayira amayamba kutsukidwa ndi cholekanitsa mafuta kuti achotse mafuta oyandama, kenako FeClⅢ coagulant (mlingo wa 400mg/L) imawonjezedwa kuti isokoneze kukhazikika kwa colloidal, ndikupanga ma flocs okhala ndi kukula kwa tinthu tating'onoting'ono>50 μ m;

Gawo lokanikiza zosefera:Pansi pa mphamvu ya chakudya ya 0.8 MPa, gawo la keke yosinthira limapangidwa pamwamba pa nsalu yosinthira, yomwe imatseka madontho a mafuta okhala ndi tinthu tating'onoting'ono toposa 1 μ m. Nthawi yomweyo, kapangidwe ka convex pamwamba pa mbale yosinthira kumalimbitsa kuwunikira kwamakina kwa mafuta osungunuka;

Gawo lofinya:Ikani mphamvu ya 1.2MPa ku keke yosefera kudzera mu dongosolo la hydraulic, onjezerani mafutawo, ndipo pamapeto pake muchepetse chinyezi cha keke yosefera kufika pansi pa 55% ndi mafuta kufika pansi pa 8%.

Kupititsa patsogolo ntchito yolekanitsa madzi olimba ndi olimba:

Dongosolo lothandizira lokha lotsitsa katundu (lokhala ndi bandwidth ya 800mm ndi liwiro lotumizira la 0.5m/s) limakwaniritsa njira yonse yodziyimira yokha ya kusefera, kutsitsa katundu, ndi mayendedwe a kuthamanga:

Mgwirizano wanzeru:Pambuyo poti makina osindikizira a fyuluta amaliza kugwira ntchito kamodzi (pafupifupi mphindi 45), mbale yosindikizira imatseguka yokha ndipo keke yosindikizira imatsikira pansi kupita ku lamba wonyamulira ndi mphamvu yokoka;

Kapangidwe kotsutsana ndi kumatira:Pamwamba pa lamba wonyamulira katundu pamakhala chophimba cha PTFE, chophatikizidwa ndi chipangizo chopopera madzi champhamvu, kuti apewe kutsekeka komwe kumachitika chifukwa cha kumatirira kwa keke yosefera;

Kugwiritsa ntchito zinthu:Keke yosefera yokhala ndi chinyezi cha 55% ingagwiritsidwe ntchito mwachindunji ngati chakudya, ndipo akuti ikhoza kupanga ndalama zokwana mayuan 120000 pachaka.

Makina osindikizira a fyuluta amtundu wa bokosi:Yokhala ndi makina owongolera a PLC, imatha kusintha yokha kuthamanga kwa chakudya ndi nthawi yokankhira malinga ndi mtundu wa madzi olowera. Deta yeniyeni yoyesera ikuwonetsa kuti magetsi omwe amagwiritsidwa ntchito pokonza tani imodzi ya madzi otayira ndi 0.85 kWh yokha, yomwe ndi yotsika ndi 40% poyerekeza ndi makina osindikizira achikhalidwe a mbale ndi chimango;

Lamba wonyamula katundu:Cholumikizidwa bwino ku doko lotulutsira la makina osefera, pogwiritsa ntchito kapangidwe kake, chingasinthe mwachangu ziwalo zosweka, ndipo nthawi yokonza imakulitsidwa mpaka miyezi 6.

3,Zotsatira za kukhazikitsa ndi phindu la zachumaUbwino wa chilengedwe:

Kuchuluka kwa mafuta m'madzi otayira kwatsika kuchoka pa 120mg/L isanakonzedwenso kufika pa 12mg/L, ndi kuchuluka kwa COD yochotsa mafuta ndi 97% komanso kuchepa kwa mafuta otulutsa mafuta pafupifupi matani 28 pachaka;

Chinyezi cha keke yosefera chinachepa ndi 20%, ndipo kuchuluka kwa matope omwe amatumizidwa kunja kunachepa kuchoka pa matani 60 pamwezi kufika pa matani 22, zomwe zinachepetsa ndalama zoyendera ndi pafupifupi 70%.

magwiridwe antchito azachuma:

Ndalama zomwe zimapezedwa pachaka kuchokera ku kugwiritsa ntchito keke yosefera ndi 120000 yuan, zomwe zimachotsa 60% ya mtengo wochepa wa zida zosefera;

Mtengo wophatikizana wa magetsi ndi mankhwala watsika ndi 35%, zomwe zapangitsa kuti ndalama zogwirira ntchito zisungidwe pafupifupi 250000 yuan pachaka.

Zotsatira za anthu pagulu:

Pambuyo pa kukhazikitsidwa kwa polojekitiyi, kampaniyo idapereka satifiketi ya ISO 14001 yoyang'anira zachilengedwe, kukhala muyezo wotetezera chilengedwe m'makampani opanga zinthu zam'madzi am'deralo ndikulimbikitsa kukweza kwa kupanga zinthu zobiriwira m'chigawo.

4, Ndemanga za Makasitomala

Mwa kuyambitsa njira yophatikizana ya makina osindikizira zosefera amtundu wa bokosi ndi lamba wonyamulira, tathetsa kwathunthu vuto lakale la kuyeretsa madzi otayira. Tsopano, sitingathe kungotulutsa madzi mokhazikika komanso moyenera, komanso keke yosefera ingagwiritsidwenso ntchito ngati zopangira chakudya kuti tipeze ndalama zowonjezera. Luntha la chipangizochi limaposa zomwe zimayembekezeredwa, ndipo ndalama zogwirira ntchito ndi kukonza zachepetsedwa ndi pafupifupi theka.
