1, Nhoroondo yeProjekiti
Donghai Fisheries Co., Ltd., iri muPeru, ikambani yemazuva ano yekugadzira hove dzemumagaba ine kugona kugadzira matani 10000 pagore. Mvura yakasviba inogadzirwa panguva yekugadzira kwayo ine hunhu hwakajairika muindasitiri: mvura yakasviba inobuda zuva nezuva inosvika matani 800, huwandu hwemafuta hunosvika 350-400mg/L, zvichipfuura mwero wekubuda, uye inewo huwandu hwakawanda hweprotein, marara ehove, uye zvinhu zvekugadzirisa zvakasara. Kuwanda kweCOD kuri pakati pe2500-3000mg/L kwenguva yakareba. Maitiro echinyakare e "grid+air flotation+biochemistry" anogona kubvisa zvimwe zvinosvibisa, asi kushanda kwemaitiro ekusefa kwepressure kwakaderera, uye huwandu hwehunyoro hwekeke rekusefa hwakakwira kusvika 75%, izvo hazvingogumiri pakuwedzera kwakanyanya kwemutengo wekugadzirisa tsvina inotevera, asiwo huwandu hwemafuta mutsvina huchiri kuchinja pakati pe80-120mg/L, zvichiita kuti zviome kuwana mwero wakagadzikana.
2, Matambudziko Makuru uye Mhinduro
Matambudziko ekuparadzanisa mafuta:
Mafuta ari mumvura yehove yakachengetwa mumagaba anowanikwa mune ese ari maviri akasanganiswa neakasungirirwa, uye maitiro echinyakare ekufamba kwemhepo akaoma kupwanya zvachose emulsion. Chikwata chepurojekiti chinosumamuchina wekudhinda wekamuri re hydraulic unodzorwa nechirongwa, yakabatana nejira re polypropylene rinodzivirira mafuta, kuti mafuta agare kwenguva refu kuburikidza nekusefa kwematanho matatu:
Danho rekutanga kurapwa:Mvura yakasviba inotanga yagadziriswa nemuchina wekuparadzanisa mafuta kuti ibvise mafuta anoyangarara, uye ipapo FeClⅢ coagulant (muyero we400mg/L) inowedzerwa kukanganisa kugadzikana kwecolloidal, zvichiita kuti pave nemaflocs ane saizi ye particles>50 μm;
Danho rekudzvanya sefa:Pasi pekumanikidzwa kwekudya kwe0.8 MPa, jira rekeke rinoshanduka rinoumbwa pamusoro pejira rekusefa, iro rinobata madonhwe emafuta ane saizi yechinhu chikuru kupfuura 1 μ m. Panguva imwe chete, chimiro che convex pamusoro peplate yekusefa chinosimbisa kuvharwa kwemafuta e emulsified;
Danho rekudzvanya:Isa kumanikidzwa kwe1.2MPa pakeke rekusefa uchishandisa hydraulic system, wobva waburitsa mafuta, wozopedzisira waderedza hunyoro hwekeke rekusefa kusvika pasi pe55% uye huwandu hwemafuta kusvika pasi pe8%.
Kuvandudzwa kwekushanda kwekupatsanurana kwemvura yakasimba:
Sisitimu yebhandi rekutakura rinoburitsa otomatiki (ine bandwidth ye800mm uye kumhanya kwekutakura kwe0.5m/s) inoita kuti pressure filtration, unloading, uye transport iite otomatiki:
Kubatana kwakangwara:Mushure mekunge firita yapedza kutenderera kamwe chete (maminitsi angangoita makumi mana nemashanu), ndiro yefirita inovhurwa yega uye keke refirita rinotsvedza richidzika kubhandi rekutakura zvinhu negiravhiti;
Dhizaini yekudzivirira kunamira:Pamusoro pebhandi rekufambisa zvinhu panoiswa chifukidziro chePTFE, pamwe chete nechishandiso chekupfapfaidza mvura chine simba guru, kudzivirira kuvharika kwekutakura zvinhu kunokonzerwa nekunamira keke refirita;
Kushandiswa kwezviwanikwa:Keke rekusefa rine hunyoro hwe55% rinogona kushandiswa zvakananga sechikafu chezviyo, uye zvinofungidzirwa kuti rinogona kuwana mari inosvika 120000 yuan pagore.
Muchina wekupfapfaidza werudzi rwebhokisi:Yakashongedzerwa nePLC control system, inogona kugadzirisa otomatiki kumanikidzwa kwekudya uye nguva yekudzvanya zvichienderana nehunhu hwemvura inopinzwa. Ruzivo rwechokwadi rwekuyedza runoratidza kuti kushandiswa kwemagetsi pakuchenesa tani imwe chete yemvura yakasviba i0.85 kWh chete, iyo yakaderera ne40% pane michina yekupfapfaidza yeplate nefuremu;
Bhandi rekutakura zvinhu:yakabatana zvakanaka nechiteshi chekubuditsa chemuchina wekusefa, ichitora dhizaini yemodular, inogona kutsiva zvikamu zvakasakara nekukurumidza, uye nguva yekugadzirisa inowedzerwa kusvika kumwedzi mitanhatu.
3,Mhedzisiro yekushandiswa uye mabhenefiti ehupfumiZvakanakira zvakatipoteredza:
Mafuta ari mutsvina akaderera kubva pa120mg/L isati yagadziriswa kusvika pa12mg/L, neCOD removal rate ye97% uye kudzikira kwegore negore kweanenge matani makumi maviri nemasere emafuta anoburitswa;
Hunyoro hwekeke rekusefa hwakaderera ne20%, uye huwandu hwetsvina inotakurwa kunze hwakaderera kubva pamatani makumi matanhatu pamwedzi kusvika pamatani makumi maviri nemaviri, zvichideredza mari yekufambisa neinenge 70%.
mashandiro ehupfumi:
Mari inowanikwa pagore kubva mukushandiswa kwezviwanikwa zvekeke rekusefa i120000 yuan, zvichideredza 60% yemari yekuderera kwemutengo wemidziyo yekusefa;
Mari inoshandiswa pamagetsi nemishonga yakadzikira ne35%, zvichikonzera kuti pagore pave nemari inoshandiswa pakushanda inosvika 250000 yuan.
mhedzisiro yemagariro evanhu:
Mushure mekuitwa kwechirongwa ichi, kambani iyi yakapasa chitupa cheISO 14001 Environmental Management System, chikava chiyero chekuchengetedzwa kwezvakatipoteredza muindasitiri yekugadzira zvigadzirwa zvemumvura munharaunda uye kukurudzira kuvandudzwa kwedanho rekugadzira zvinhu zvakasvibira munharaunda.
4, Ongororo dzevatengi
Nekuunza mhinduro yakasanganiswa yebhokisi rebhokisi rekusvina firita nebhandi rekufambisa, tagadzirisa zvachose dambudziko renguva refu rekurapa mvura yakasviba. Iye zvino, hatigone chete kuburitsa mvura yakasviba zvakanaka, asi keke rekusvina rinogona kushandiswawo sezvinhu zvekudya kuti tiwane mari yekuwedzera. Hungwaru hwemuchina uyu hunopfuura zvakanyanya zvinotarisirwa, uye mari yekushandisa nekugadzirisa yaderedzwa neinenge hafu.
