Seageheni yechipatara inoreva nezvechipatara chinogadzirwa nezvipatara zvine hutachiona, simbi dzinorema, dzinoshungurudza, organic sols, acids, alkalis, uye radioactivity. Iyo ine maitiro ekusvibiswa nesptial kusvibiswa, kutapukira kwakasimba, uye kutapukirwa kwekutanga. Pasina kurapwa kunobudirira, inogona kuve nzira yakakosha yekupararira kwezvirwere uye kusvibisa zvakatipoteredza. Saka, kuvakwa kwe Kurapa kweSewagechirimwaMuzvipatara zvave kiyi yekugadzirisa dambudziko iri.
1.Chipatara chechipatara chekuunganidza uye kunyepedzera
Iyo purojekiti inotora sosi yemukati uye mvura yemvura yekuyerera kwePipeline system, inoenderana nehurongwa hwemadhorobha. Sangano rekurapa uye kushomeka kwechipatara munzvimbo yechipatara vanounganidzwa pombi yemuchadenga. Mushure mekusangana neyekubvisa mwero wemvura plloutants discharge
Maincessing unit rondedzero yeKurapa kweSewagechirimwa
① Iyo grid tso yakashongedzwa neyakagadzirirwa maviri ematehwe ematehwe uye akanaka grid, ine gidhi yemakumi matatu mm pakati pegridal cridals uye 10 mm pakati pe grids yakanaka. Batisisa hombe zvikamu zvekumiswa zvinhu uye zvakanyanyisa zvakapfava zvinhu zvinyoro-nyoro (zvakadai sepepa scrips, rags, kana chikafu chasara) kuchengetedza pombi yemvura uye inotevera yekugadzirisa zvikamu. Pakuisa, grating inofanira kuremerwa pazinga makumi matanhatu kusvika makumi matanhatu kusvika pamhepo yakatwasuka yemvura inoyerera inoyerera yekubvisirwa kwekubviswa kwevakabvaruka. Kuti udzivise pombi sedimentation uye kupararira kwezvinhu zvakadzivirirwa, dhizaini yacho inofanirwa kuchengetedza iyo seage yekuyerera isati yatanga Izvo zvinhu zvakavharirwa nehukutra inofanirwa kubviswa panguva yekubviswa nekuda kwekuvapo kwehuwandu hukuru hwehutachiona hombe.
② Kutora Dziva
Iye masisitimu edhirowa echipatara anotema mhando dzisina kufanana hwemvura inouya kubva kuchiteshi chekurapa kwegungwa. Naizvozvo, tangi yekudzora yakaiswa kuHomogenize mhando uye huwandu hweswage uye kuderedza kukanganiswa kwemhedzisiro yemitoro pane yakazotevera kurapwa kwekurapa. Panguva imwecheteyo, simudza tsaona yakawedzera pombi kune dzimba dzetsaona. Zvishandiso zvegasheji zvakaiswa mumatangi ekudzora kuti udzivise iyo singiventation yezvikamu zvakamiswa uye kugadzirisa biodegradability yemarara.
③ hypoxic aerobic dziva
Inopisa Aerobic tangi ndiyo core maitiro ekurapa kwekurapa. Kubatsirwa kwacho kuri kuwedzera kune kushatisa organic pollutants, zvakare ine rimwe basa re nitrogen ne phothorus kubviswa. Iyo A / O maitiro anobatanidza kumberi kweAnaerobic chikamu uye kumashure kweAerobic chikamu muzvikamu, nechikamu chisingapfuure 0.2 mg / l uye o chikamu chikaita = 2 mg / l-4 mg / l.
Muchikamu chezenji, Heterotrophic Bactia Hydrolyze Pollutants yakadai sehunhu, maCarbohydrates mune organic Acids, inokonzeresa macromolecular zvinhu zvekusarudza kuita madiki madiki mbozha. Insoluble organic zvinhu inoshandurwa kuita sexuble organic nyaya. Kana izvi zvigadzirwa zveAnaerobic Hydrolysis pinda iyo Aerobic Tank yeAerobic kurapwa, iyo Biodergradability yeSewage inovandudzwa uye kushanda kweokisijeni kunovandudzwa.
Muchikamu chezokisi, heterotrophic bactia inogadzira pollutants yakadai sepuroteni uye mafuta (n pane iyo organic ketju kana amino acid muAmoni (NH3, NH3 +). Pasi pemamiriro ezvinhu akakwana okisijeni, iyo notration ye autotrophic bactia oxidize nh3-n (n (nh4 +) kusvika ku3 - uye inodzokera kune pool actux kudzora. Pasi pemamiriro ezvinhu ezviitiko, kudengenyeka kweHeterotrophic Bactia kunodzora Nitrogen (n2) kupedzisa kutenderera kweC, n, uye o mune ezvekurapa uye kuziva zvisina kukuvadzwa kurapwa.
④ Tangi yekufema
Iyo firita inopinda mukusafarirwa tangi yekuwongorora kuti urambe uine imwe nguva yekufonera pakati pechikwangwani uye chisingazivikanwe, chichiona kuti kusawirirana kunouraya mabhakitiriya mumvura. Iyo effluent inodzingwa mumusuru wepombi yemapipi. Maererano ne "mvura isina kupfekedza masangano ekurapa", nguva yekunyepedzera kubva kune hutachiona hwehutachiona hwehutachiona hachifanirwe kunge zvisingasviki 1,5, uye nguva yekunyepedzera kubva pazvipatara zvakazara hazvisi pasi pe1.0 awa.
