Zvishandiso Zvitsva zveMahara zveSewage Equipment
Hunhu hwetsvina yemumba yekumaruwa hunosanganisira mvura yekubikisa mukicheni, yekugeza, yekugeza, uye yekugezesa muchimbuzi.Zvitubu zvemvura izvi zvakapararira uye hakuna nzvimbo dzekuunganidza mumaruwa.Nekukurwa kwemvura inonaya, inoyerera ichienda mumvura, mvura yevhu, uye pasi pemvura yakaita senzizi, madziva, migero, madziva, uye madhamu.Izvo zvakakwirira zvezvakagadzirwa zvehupenyu ndicho chimiro chikuru.
Inoda kuti zviratidzo zvose zvetsvina mushure mekurapwa zvinosangana ne "Comprehensive Wastewater Discharge Standard" GB8978-1996;First level zviyero zve.Mushure mekunge michina yaiswa mukushandiswa, inogona kuderedza kubuda kwetsvina, kuderedza kusvibiswa kwezvakatipoteredza, uye kushandisa zvizere zviwanikwa zvemvura kuita zero.
Dhizaini misimboti yemidziyo mitsva yekumaruwa yekuchenesa tsvina yekumaruwa:
1. Kushandisa mitemo yenyika pamusoro pekuchengetedza kwezvakatipoteredza, uye kushandisa mitemo yenyika uye yemunharaunda, mitemo, tsika, uye mitemo yakakodzera;
2. Papfungwa yekuti tsvina inosangana nezvinodiwa pakurapwa, kuedza kunofanirwa kuitwa kuchengetedza mari uye kukwidziridza zvizere mabhenefiti emagariro, ehupfumi, uye kwezvakatipoteredza emapurojekiti ekuchenesa tsvina;
3. Sarudza nzira yekugadzirisa inoshanduka, iri nyore kushanda uye kutonga, uye ine mabasa akagadzikana uye akavimbika;
4. Mukugadzira, edza kupatsanura zvinoenderana nemabasa uye edza compactness uchive nechokwadi chekugadzirisa kushanda.
5. Edza kufunga nezvekushandisa otomatiki mukugadzira kudzikisa kusimba kwevashandi;
6. Funga nezvezviyero zvakadai sekuvhunduka, kuderedza ruzha, uye deodorization yekutsigira hurongwa hwekuchenesa tsvina kubvisa kusvibiswa kwechipiri kune zvakatipoteredza.
Nheyo dzekusarudza maitiro emidziyo yekuchenesa tsvina yemumba munzvimbo nyowani dzekumaruwa:
Kune akawanda organic tsvina mutsvina yemumba, ine yakakwira CODcr uye BOD5, uye BOD5 / CODcr kukosha kukuru kupfuura 0.4, inoratidza yakanaka biochemical performance.Zvinokurudzirwa kutora biochemical based process yekurapa.Nekuda kwehuwandu hwemvura yetsvina, yakavigwa yakasanganiswa yekuchenesa tsvina michina inofanirwa kushandiswa kurapa biochemical.Usati wapinda biochemical mudziyo, edza kubvisa inoyangarara uye hombe particle yakaturikwa tsvina kubva mudzimba tsvina panguva pre-kurapwa nhanho sezvinobvira, uye ipapo kupinda tsvina inodzora tangi kudzivirira zvakaipa migumisiro pombi kusimudza tsvina.
Mvura yetsvina yemumba inocheneswa mune septic tank.Mvura yekugeza yetsvina inosanganiswa nedzimwe tsvina mushure mekunge yacheneswa nemuunganidzi webvudzi yobva yapinda museptic tank.Mushure mokusimudzwa nepombi, inoyerera nepakati pegridi uye inopinda mumvura inogadzirisa tangi mushure mokubvisa tsvina yakakura yakamiswa.Iyo tsvina mutangi inogadzirisa inosimudzwa nepombi yekusimudza uye inopinda mumichina yekuchenesa tsvina yakabatanidzwa.Iyo tsvina mumidziyo inobatwa ne hydrolysis acidification, biological contact oxidation, sedimentation uye mamwe maitiro, uye yobva yapinda musefa, Mushure mekusefa nekuuraya hutachiona, iyo inoyerera inosangana nezviyero uye inoburitswa kuti isvibire.Iyo inogadzirisa sludge inogadzirwa ne sedimentation tangi mune yakasanganiswa midziyo inotakurwa kune sludge tank mune yakasanganiswa michina kuburikidza nemhepo inobvisa.Madhaka acho anonyudzwa, anogadzikwa, uye anogayiwa mudhaka remarara, uye iyo supernatant inodzoserwa kutangi rekudzora kuti igadziriswe zvakare pamwe chete nemvura yekutanga yetsvina.Dope rakanyura rinogara richipombwa uye kutakurwa kunze nerori remupfudze (kamwe chete mwedzi mitanhatu yega yega).
Kuongororwa kwemaitiro emidziyo yekuchenesa tsvina yemumba munzvimbo nyowani dzekumaruwa:
① Grille
Iyo grille inogadziriswa uye yakagadzirwa nesimbi isina tsvina mesh.Misa mitsara miviri yakakora uye yakatsetseka kuti ubvise zvidimbu zvakarembera uye tsvina inoyangarara mumvura.
② Kudzora tangi uye pombi yekusimudza
Nekuda kwekuchinja kukuru kwemhando uye huwandu hwetsvina, zvinodikanwa kuve neakakwana ekudzora tanki kuitira kudzikamisa mhando yemvura uye huwandu hunopinda mumidziyo yekuchenesa tsvina yakabatanidzwa.
Iyo tangi yekudzora inoshongedzerwa nepombi inoyerera yetsvina yekusimudza mvura yetsvina kuenda kune yakasanganiswa sewage michina.
③ Hydrolysis acidification tank
Iyo hydrolysis acidification tangi yakashongedzerwa neanosanganiswa mafirita.Pasi pechiito che hydrolysis uye acidification microorganisms mutangi iri, mvura yetsvina inogadziriswa hydrolyzed uye acidified kuita diki mamorekuru zvinhu ne macromolecular organic tsvina, izvo zvinokonzeresa kuparara kweaerobic bacteria mune yekusangana oxidation tank.
④ Biochemical kurapwa
Zvichienderana nemhando yambotaurwa yesuweji, huwandu, uye zvinodiwa pakubuda, zvakasanganiswa nehunhu hwetsvina.Iyi biochemical system ichabatanidza iyo yekubata oxidation tangi, sedimentation tank, sludge tank, fan room, disinfection outlet tank, uye zvimwe zvikamu mune imwe.Chikamu chimwe nechimwe chine mabasa anoenderana uye chakabatana kune chimwe nechimwe, uye tsvina yekupedzisira inosangana nechiyero.Zvinotevera zvinotsanangurwa zvakasiyana:
Zadza iyo yekusangana oxidation tangi nemafiller.Chikamu chezasi chine aerator, uye aeration system inogadzirwa neABS engineering epurasitiki pombi.Mhepo sosi yeaeration system inopihwa neakanyatso gadziridzwa fan.
Chikamu chepamusoro chetangi ye sedimentation yakashongedzerwa neinogadziriswa yekubuda weir kuti igadzirise iyo yekubuda kwemvura mwero;Chikamu chezasi chakashongedzerwa neconical sedimentation zone uye sludge air lift mudziyo, ine mhepo sosi inopihwa nefani.Dope rinotakurwa kuenda kudhaka redhaka kuburikidza nemhepo inosimudza.Nguva yekuchengetedza yematope mudhangi redhaka inenge mazuva makumi matanhatu.Iyo sludge inogadzirwa neiyo system sedimentation inodururwa mudhaka tangi nekusimudza kwemhepo, uko sludge inodzika, inogarwa uye kuchengetwa.Mapombi emhepo akaiswa pazasi petangi kudzivirira sludge anaerobic digestion kubva pakugadzira biogas, uye kuti oxidize the sludge kuderedza huwandu hwese hwemadhaka;Dope rakanyura rinogara richipombwa uye kutakurwa nemarori emupfudze.Chikamu chepamusoro chetangi remarara chine supernatant reflux mudziyo wekupfachukira iyo supernatant kune acid hydrolysis tank.
⑤ Disinfection: Isati yabuda kwekupedzisira, disinfected ne chlorine dioxide.
