Lopangidwa kuyeretsa madzi zinyalala: njira, mbali ndi dera

Today pali mankhwala, thupi, makina ndi mankhwala zamoyo madzi ogwiritsidwa ntchito. Iwo amasiyana chikhalidwe cha njira akuzionera, komanso magawo ndondomeko. Tiganizire moposera, kodi njira makina mankhwala zimbudzi.

mwachidule

Zinyalala madzi ntchito madzi mafakitale ndalama. Ntchito mu zolinga za mafakitale, iwo ayenera aphunzitsidwe. Pa ake kudzera kuyeretsa madzi ogwiritsidwa ntchito ku zodetsa makina. Chifukwa chaichi, wapadera zipangizo. Iwo zingasiyane malingana ndi mtundu wa zomangamanga ndi magawo ena.

mitundu ya maofesi

Pamene kusefera ntchito:

1. grates makina mankhwala madzi ogwiritsidwa ntchito.
2. Sand misampha.
3. Nembanemba zinthu.
4. Pulayimale sedimentation akasinja.
5. Septic akasinja.

nyumba zimenezi zimagwira ntchito mwa ndondomeko.

Kulunjika dera makina yoyeretsa madzi ogwiritsidwa ntchito

Mu siteji yoyamba, kumanga kuipitsidwa lalikulu la mchere ndi chiyambi organic. Chifukwa chaichi kophimba. Jaji pazipita zinthu coarse sieve ntchito. M'lifupi pazipita polankhula mu latisi wa - 16 mm. Zigawo Kutsekeledwa wake, wosweka. Kenako anatumiza pamodzi ndi mpweya wa zomera zimbudzi mankhwala yobwezeretsanso. Komanso zolimba olekanitsidwa akhoza kuwataya mu processing malo zinyansi mafakitale ndi zoweta. Pambuyo koyamba kusefera effluent ndi anadutsa msampha mchenga. Pali allocated zabwino particles dothi. Izi, makamaka pankhondo ya mandala, slag, mchenga ndi zina zotero. Mothandizidwa yokoka, iwo waikamo. Ndiye ntchito mafuta msampha. Ndi zomangamanga awa anagwira kuchotsa zinthu hydrophobic padziko madzi ndi asamire. Mchenga, pamene kudutsa anasankha misampha mchenga zambiri amasungidwa ndipo kenako ntchito mu ntchito msewu. zinthu Kakhungu ntchito kusefera zakuya. Njira imeneyi inalandira ambiri ndithu. Lopangidwa kuyeretsa madzi ogwiritsidwa ntchito Kakhungu njira imapereka kubwerera zopangira mu mkombero kupanga.

njira mafunsidwe

Lopangidwa kuyeretsa njira imeneyi ingagwiritsidwe madzi ogwiritsidwa ntchito Mwachitsanzo, kuchotsa particles inaimitsidwa. Zosefera Pankhaniyi akhoza anakonza m'njira ziwiri. Woyamba zimaphatikizapo kugwiritsa ntchito mphamvu ya kuipitsidwa yokoka. Imawalamulira m'kati yothetsa particles inaimitsidwa zakhazikika pansi. njira ina zimaphatikizapo kugwiritsa ntchito mphamvu centrifugal. Mawotchi mankhwala a madzi ogwiritsidwa ntchito njira zimenezi kungathetse zigawo insoluble, ukulu wa millimeters zomwe oposa mazana angapo. Mu ndondomeko yokonza zipangizo kachiwiri ntchito yopanga amagwiritsidwa ntchito Mipikisano mtundu septic akasinja. Pang'ono osasankhidwa feedstock akudyetsedwa pa sitepe imodzi vuto lotsatira.

flotation

Mawotchi mankhwala a madzi ogwiritsidwa ntchito njira imeneyi kulanda zoipitsa pamwamba ndi mpweya thovu. Chifukwa, pali flotation thovu mapangidwe. Iwo ali kuchotsako zigawo amachotsedwa kenako ntchito scrapers. mpweya thovu ingakhale yopangidwa ndi njira makina. Chifukwa chaichi, ndi nozzle kapena chopangira mphamvu ndi zina zotero electroflotation.

Kugwiritsa ntchito zipangizo porous

Njira imatengedwa kwambiri ambiri. Ndi zipangizo porous angathe kuthetsedwa precipitate makina yoyeretsa ya madzi ogwiritsidwa ntchito wochuluka. Pamene ntchito fyuluta chuma kapena thumba la dongosolo lapadera. Njira imeneyi ndi zogwirizana ndi ntchito yofunika ntchito madzi zobwezerezedwanso.

zimaonetsa misampha mchenga

Kuyambira maukonde kuchimbudzi effluent akudyetsedwa kuti zowonetsera ndi grills. Iwo osasankhidwa. Large zinthu - khitchini zinyalala, nsanza, pepala, etc. - ikuchitikira. Zitatero, iwo achotsedwa ndipo anatengedwa kuti decontamination ndi disinfection. The effluent osasankhidwa akudyetsedwa ku msampha mchenga. Iwo lakonzedwa kuteteza m'dziko kuipitsidwa ndi particles mchere. misampha zomangamanga mchenga angakhale osiyana. Izo zimatengera voliyumu ya zimbudzi ukubwera. misampha mchenga akhoza kukhala ofukula ndi yopingasa, komanso kudula. Mitundu iwiri yoyambirira ntchito zomera chithandizo madzi ogwiritsidwa ntchito, ndi wotsiriza - pa mitsinje. Ofukula ndi yopingasa mchenga msampha anaika, ngati voliyumu ya zipangizo ukubwera yaiwisi oposa 300 mamita ³ / tsiku. misampha mchenga zimagwiridwa ziwiri chidutswa. Izi ndi zofunika kuonetsetsa kuti m'kati kukonza amene lachiwiri bwinobwino. Mu zomangamanga yopingasa particles mchere mafunsidwe ndondomeko kumachitika pamene madzimadzi umayenda pa liwiro la 0,1 m / gawo. The ofukula mchenga catchers kusankha zosafunika ikuchitika ndi kutukula effluent pamwamba. Madzimadzi mathamangidwe pa nthawi yomweyo - 0,05 m / s.

chitayiko

Amaonedwa zofunika, choncho mitundu yofala zomera kusefera. Atsamunda akhoza kupereka yopingasa kapena ofukula kayendedwe ka madzi. Ndi wambirimbiri zipangizo ntchito ndi kumanga opareshoni mosalekeza. Ngati otaya madzi tsiku -. Osati zoposa zikwi 50 M3, akasinja ofukula Kuthetsa ntchito. Machitidwe a makhazikitsidwe monga motere. Effluents ali amaperekedwa ndi chitoliro chapakati pansi kukonza. The effluent amasuntha kuti ayambe kusonkhanitsa trays. Pa zochotsa zinthu madzi dontho ndi kulemekeza mkulu enieni. Komanso, sedimentation akasinja zozungulira mtundu ntchito kusefera.

Limatchula za processing

makampani amagwiritsa pulayimale ndi sekondale sedimentation akasinja. Ena anapereka kutsogolo kwa zida kusefera zamoyo ndi ena, motero - kuti lithandize zinyalala pambuyo pawo. Secondary sedimentation akasinja ndi kukhudzana. Ngati mtunda amalola kukha mwachindunji mu matupi a madzi, sefa dera ayenera kuperekedwa kwa masaka thanki. Kuyimitsidwa azifotokoza thanki yaikulu Kuthetsa, kuvunda. Unyinji chifukwa nafota pa malo apadera, ndipo kenako ntchito ngati feteleza ulimi.

Aerators ndi biokoagulyatory

nyumba deta mtundu anafuna zosafunika nonchemical processing ndi sludge muyeso mwa ankatenthetsa ndi madzi pogwiritsa ntchito mpweya wothinikizidwa. Aerators aumbike mwa makona anayi, amene anaika mu kugawa kutalikitsa njira ya kayendedwe ka. nyumba izi zimathandiza kuti mafotokozedwe a mlingo wa Kupha madzi mafuta. The aerators nthawi zambiri ikuchitika mawotchi kuyeretsa mafuta munali madzi ogwiritsidwa ntchito. Mu zomangamanga izi anagwiritsanso feedstock pokonzekera siteji yotsatira kusefera. Aeration - ichi atawapempherera kuti ayeretsedwe ndondomeko madzi kwa mphindi 10-30. Air otaya kudzera zosefera kapena mabowo mipope. Biokoagulyatory kupangidwa ngati yopingasa kapena ofukula Kuthetsa thanki ndi malo annular ndi gawo lapadera. Iwo zimasakanikirana kukhudzana kwambiri adamulowetsa sludge ndi madzi. Kuchepetsa mpweya otaya mu chipinda chapakati 4 ngodya kupereka triangular mphako bokosi. Pankhaniyi, pa akuya 2.5-3 mamita zakonzedwa yopingasa thanki ndi fyuluta mbale. Madzi amalowa chubu chapakati kudzera thireyi okwanira.

zomangamanga kanthu

zopangira umayamba mu coagulator malo pansipa mbale fyuluta. Zimenezi zimathandiza blockage ndi particles lalikulu. Anthu ambiri sludge pafupifupi 7 g / L. Pankhaniyi kuchuluka akhale 1% ya ndalama otaya effluent. Imathandiza mpweya wothinikizidwa umaperekedwa kwa zipangizo. Mothandizidwa adamulowetsa sludge ndi wothira madzi zinyalala ndipo anakhalabe mu boma inaimitsidwa. Choncho aeration mwamphamvu ayenera anakhalabe mu 1.8-2 mamita ² / h. The madzi ankachitira mpweya, akuyamba kuyenda motsatira ducts makope amene wokwera pa ngodya za chipinda chapakati. mpanda wake ndi wautali kuposa chidebe. The annular coalescer zone anapanga zolemeletsedwa yl wosanjikiza pakati pamalo lakunja ndi chipinda chapakati. mlingo wake kudzadalira mlingo otaya effluent. Izi wosanjikiza zolemeletsedwa amalimbikitsa coagulation kukhazikika liwiro zochotsa feedstock ndi kuthetsa directivity kuyenda ofukula za madzi.

Pomaliza

Mawotchi kuyeretsa ndi njira yofunika kwambiri mu ogwira ntchito mafakitale. M'pofunika chifukwa zimathandiza kuti akonze zamadzimadzi magawo wotsatira wa kusefera. Lopangidwa kuyeretsa Mulimonsemo sitingakane. Apo ayi, wotsatira kusefera sitepe adzakhala kwambiri akulephera. Komanso, pamaso pa Mankhwala oipitsa chachikulu tinthu angasokoneze nyumba mankhwala kwachilengedwenso. Zimenezi, kodi zikuphatikizapo ndalama zina kwa kukonza kapena m'malo zida. Kapangidwe kwa zosefera ayenera anasankha malinga limatchula za kumalo a ntchito, buku zinyalala ndi kufunika kuti adzathe ntchito oyera madzi.
