Hordhac qalab isku dhafan oo lagu daweeyo biyaha wasakhda ah
Taangiga sdimentation-ka ee la koolkooliyey waa haan isku-dhafan oo hufan oo loo qaabeeyey iyadoo loo eegayo aragtida sedimentation-ka-hoose, oo sidoo kale loo yaqaan haanta suuxdinta dhuuxa ee u janjeerta.Tuubooyin badan oo cufan ama taargo leexleexan ayaa lagu dejiyay aagga dejinta si ay u soo dedejiyaan wasakhda hakadka ku jirta ee biyaha ku jira taarikada u janjeerta ama tuubooyinka.Biyuhu waxay u socdaan kor iyagoo raacaya taarikada u janjeerta ama tuubooyinka leexleexda, iyo dhoobada kala go'an waxay hoos ugu soo dhaadhacdaa xagga hoose ee taangiga iyada oo hoos imanaysa ficilka cuf-jiidadka, ka dibna waa la uruuriyaa oo la sii daayaa.Dooxada noocan oo kale ah waxay kordhin kartaa waxtarka roobabka 50-60% waxayna kordhin kartaa awoodda wax-qabadka 3-5 jeer isla aagga.Kala-saarista tuubbada fidsan ee leh heerarka socodka kala duwan waxaa loo qaabayn karaa iyadoo loo eegayo xogta tijaabada ee biyaha wasakhda ah ee asalka ah, iyo flocculant waa in lagu daraa guud ahaan.
Marka loo eego jihada dhaq-dhaqaaqooda wadajirka ah, waxaa loo qaybin karaa saddex nooc oo kala soocis ah: Dib-u-dhac (kala-duwan) Socod, Isku-socod isku mid ah iyo qulqulka dambe.Inta u dhaxaysa labada taariko ee isbarbar socda (ama tuubooyinka isbarbar socda) waxay u dhigmaan haanta suuxdinta gacmeed.
Marka ugu horeysa, taangiga qulqulka qulqulaya ee qulqulka kala duwan (qulqulka gadaale), biyuhu waxay ka soo qulqulaan hoosta, iyo dhoobada degdega ah ayaa hoos u dhacaya, saxanka u janjeera guud ahaan waxaa la dhigaa xagal 60 ° ah, si loo fududeeyo duleelka dhoobada degdega ah.Marka ay biyuhu dhex maraan saxanka u janjeedha, qaybuhu way degayaan oo biyuhu way caddaanayaan.Isla socodka saxanka u janjeera (tube) haanta sedimentation, jihada biyuhu ka soo qulqulayaan xagga sare, iyo jihada qulqulaya ee dhoobada degdega ah waa isku mid, sidaas darteed waxaa loo yaqaan qulqul isku mid ah.Sababtoo ah socodka hoose ee biyuhu wuxuu kor u qaadaa qulqulka dhoobada wasakhda ah, xagasha u janjeerta ee saxanka u janjeedha ee taangiga sedimentation socodka isku midka ah waa 30 ° ~ 40 °.
Faa'iidooyinka taangiga dejinta ee leexsan
1) Mabda'a socodka laminarka waxaa loo isticmaalaa si loo hagaajiyo awoodda farsamaynta ee taangiga sedimentation ama haanta dejinta tuubada slanted.
2) Yaraynta fogaanta dejinta ee walxaha, sidaas darteed soo gaabin wakhtiga roobabka;
3) Aagga roobka ee weelka wasakhaysan tuubada leexleexday waa la kordhiyaa, sidaas awgeed waxay hagaajinaysaa waxtarka daaweynta.
4) Heerka saarista oo sarreeya, wakhtiga degenaanshaha oo gaaban iyo raad yar.
Taangiga dajinta tuubada u janjeerta / tuubada dejintu waxay isticmaashaa aragtida taangiga gacmeed, heerka qulqulka wuxuu gaari karaa 36m3 / (m2.h), kaas oo 7-10 jeer ka sarreeya awoodda farsamaynta ee haanta guud ee wasakhda.Waa nooc cusub oo ah qalab sementation oo hufan.
Goobta Codsiga
1, Warshadaha Korantada: Biyaha wasakhda ah ee ka kooban noocyo kala duwan oo bir ah oo isku dhafan oo isku dhafan, Ming, copper, iron, zinc, nikkel saarista ayaa ka sarreeya 90%, guud ahaan electroplating biyaha wasakhda daaweynta ka dib waxay buuxin kartaa heerarka dheecaanka.
2, Miinada dhuxusha, aagga macdanta: biyaha wasakhda ah waxay samayn karaan turbidity 500-1500 mg / L ilaa 5 mg / L.
3, Midabaynta, midabaynta iyo warshadaha kale: heerka saarista midabka biyaha wasakhda ah ee 70-90%, COD saarista 50-70%.
4, Hargaha, cuntada iyo warshadaha kale: ka saarida biyaha wasakhda ah ee tiro badan oo ah walxaha organic, COD heerka saarista 50-80%, heerka saarista wasakhda adag in ka badan 90%.
5. Warshadaha Kiimikada: heerka COD ka saarista biyaha wasakhda ah waa 60-70%, saarista chroma waa 60-90%, arrinta laalana waxay gaartaa heerka dheecaanka.
