Sifeynta Saliidda Biyaha wasakhda ah
Fikradda daaweynta biyaha wasakhda ah ee sifaynta saliidda
Biyaha wasakhda ah ee sifaynta saliidda ayaa laga soo saaraa habab kala duwan oo ka dhex jira warshadaha sifaynta, oo ay ku jiraan habaynta saliidda cayriin, nadiifinta, nadiifinta, iyo dildilaaca catalytic. Biyaha wasakhda ah waxay ka kooban yihiin wasakhyo kala duwan sida hydrocarbons, adkaha la hakiyey, biraha culus, sulfides, phenols, iyo xeryahooda kale ee organic, kuwaas oo saameyn weyn ku yeelan kara deegaanka haddii aan si habboon loo daaweyn.
Hadafka sifaynta saliida ee daaweynta biyaha wasakhda ah waa in meesha laga saaro wasakhaynta waxyeelada leh si loo daboolo xaddidaadda dheecaanka sharciyeynta, ka hortagga waxyeelada deegaanka, iyo dib u warshadaynta biyaha marka ay suurtagal tahay. Isku darka hababka daaweynta jirka, kiimikaad, iyo bayooloji ayaa caadi ahaan loo shaqeeyaa si loo xakameeyo dabeecadda adag ee biyaha wasakhda ah.
Astaamaha lagu sifeeyo saliidda biyaha wasakhda ah
1. Culayska Dabiiciga ah ee Sare: Biyaha wasakhda ah ee sifaynta saliiddu waxa ay inta badan ku jiraan heerar aad u sarreeya oo ah hydrocarbons kala diri iyo kala firidhsan, sida benzene, toluene, iyo xylene, taas oo gacan ka gaysanaysa Baahida Ogsajiinta Kiimikada sare (COD) iyo Baahida Ogsajiinta Biyochemical (BOD).
2. Jiritaanka Isku-dhafka Sunta ah: Biyaha wasakhda ah waxay ka kooban yihiin xeryahooda organic sunta ah sida phenols iyo polycyclic aromatic hydrocarbons (PAHs), iyo sidoo kale biraha culus (tusaale, meerkuri, rasaas, iyo cadmium), kuwaas oo waxyeelo u geysan kara hababka daaweynta noolaha.
3. Adag Lalaalay oo Sare: Sababtoo ah joogitaanka dhoobada, adkaha la hakiyey, iyo saliidaha emulsified, nidaamyada daawaynta waxay u baahan yihiin inay wax ka qabtaan labadaba kala-soocida jireed ee adkahaan iyo burburka wasakhowga kala diri.
4. Isbedbeddelka Halabuurka: Sifooyinka biyaha wasakhdu aad bay u kala duwanaan karaan iyadoo lagu saleynayo hawlaha warshadaynta, una baahan hababka daawaynta ee la qabsan karo oo xamili kara kala duwanaanshaha pH, saliinity, iyo uruurinta wasakhaysan.
5. Biyodegradability hooseeya: Qaar badan oo ka mid ah xeryahooda ku jira biyaha wasakhda ah ee sifaynta saliidda way adag tahay in la baabiiyo, taas oo ka dhigaysa daaweynta bayoolojiga mid aad u adag marka loo eego biyaha wasakhda ah ee caadiga ah.
Astaamaha habka sifaynta saliida ee biyaha wasakhda ah
1. Daaweynta Aasaasiga ah: Talaabada ugu horeysa waxay inta badan ku lug leedahay hababka jirka sida kala-soocida saliida-biyaha (tusaale, API separators), sabbeynta hawada kala diri (DAF), iyo taangiyada wasakhaysan si looga saaro saliidaha bilaashka ah, adkaha adag, iyo qaar ka mid ah biraha culus.
2. Daawaynta Sare (Daawaynta Nafleyda): Tani waa halka ay ka ciyaaraan dhaq-dhaqaaqa sariirta biofilm reactor (MBBR) ama hababka dhoobada firfircoon ee firfircoon. MBBR, gaar ahaan, waxa ay xamili kartaa culaysyo dabiici ah oo sarreeya, waxa ay u adkaysataa shoog sun ah, waxaanay u baahan tahay meel ka yar hababka caadiga ah. Waxay isticmaashaa warbaahinta caagga ah ee biofilm-ku-daboolan si ay u naaquso wasakhowga organic, iyaga oo u beddelaya kaarboon laba ogsaydh iyo biyo.
3. Daaweynta Saddexaad: Hababka sare sida sifaynta xuubka (tusaale, ultrafiltration, reverse osmosis), oxidation kiimikaad, iyo adsorption kaarboonka firfircoon ayaa loo shaqeeyaa si meesha looga saaro wasakhowga soo hadhay ee milmay, gaar ahaan organics recalcitrant iyo biraha raadraaca.
4. Xakamaynta Walaxda: Warshaduhu waxay abuuraan xadi aad u badan oo dhoobo ah, kaas oo ay tahay in la dejiyo oo si badbaado leh loo tuuro. Biyo-baxa, dhumucyada, iyo gubidda ayaa ah hababka daaweynta dhoobada ee caadiga ah.
Shuruudaha Gaarka ah ee Warbaahinta MBBR Marka lagu isticmaalo Haamaha Hawo-mareenka Nafleyda ee sifaynta biyaha wasakhda ah.
1. Aagga Dusha Sare: Warbaahinta MBBR ee loo isticmaalo sifaynta saliidda biyaha wasakhda ah waa inay bixiso aag weyn oo dusha sare ah oo loogu talagalay lifaaqa biofilm si kor loogu qaado dhaqdhaqaaqa microbial iyo xaalufka wasakhaysan. Warbaahintu waa in ay taageertaa kobaca nooleyaal khaas ah oo awood u leh inay jebiyaan hydrocarbons iyo walxo kale oo kakan.
2. U adkaysiga Wasakhaynta: Saliida badan iyo waxyaabaha adag ee la hakiyay awgeed, saxaafadu waa inay u adkaysataa wasakhaynta iyo xidhitaanka. Tani waxay hubinaysaa in biofilm-ku uu sii ahaado mid firfircoon oo habka daaweynta uu yahay mid hufan iyada oo aan si joogto ah loo nadiifin ama loo beddelin warbaahinta.
3. Waarta xaaladaha adag: Warbaahintu waa in ay u adkaysataa kala duwanaanshaha pH, cusbada, iyo heerkulka caadiga ah ee biyaha wasakhda ah ee sifaynta saliidda. Qalab adag, kiimiko ahaan deggan sida polyetylen cufnaanta sare (HDPE) ayaa caadi ahaan la isticmaalaa.
4. Hawo-mareen wax-ku-ool ah: Warbaahintu waa in ay la jaan-qaadaan nidaamka hawada ee taangiyada noolaha si loo hubiyo wareejinta saxda ah ee ogsajiinta, taas oo muhiim u ah noolaha aerobic-ka ee burburiya wasakhowga. Warbaahinta leh dhaq-dhaqaaq wanaagsan oo socodka ah ayaa xoojisa qaybinta ogsijiinta dhammaan reactor-ka.
5. La qabsiga Shooxyada Sunta ah: Biyaha wasakhda ah ee sifaynta saliiddu waxay mararka qaarkood ku jiri karaan xadhko degdeg ah oo sun ah. Warbaahinta MBBR iyo filimaanta noole ee la xidhiidha waa in ay u adkeystaan shoogagan, iyaga oo ilaalinaya dhaqdhaqaaqa bayoolojiga xitaa marka lagu jiro diiqada.
Gabagabo
Sifeynta saliidda biyaha wasakhda ah waa mid adag, waxay u baahan tahay isku darka jireed, kiimiko, iyo hababka bayooloji si meesha looga saaro wasakhda sida hydrocarbons, biraha culus, iyo xeryahooda kale ee sunta ah. Isticmaalka tignoolajiyada MBBR ee haamaha hawo-qaadista nafleyda waxay bixisaa xal wax ku ool ah oo lagu maaraynayo culayska dabiiciga ah iyo kala duwanaanshaha biyaha wasakhda ah ee sifaynta saliidda. Si kastaba ha ahaatee, guusha nidaamka MBBR waxay si weyn ugu xiran tahay sifooyinka warbaahinta la isticmaalo. Warbaahinta MBBR waa in ay u adkaysataa wasakhaynta, waarta, bixisa meel sare oo sare, oo ay taageerto wareejinta ogsijiinta oo hufan, taas oo ka dhigaysa mid si fiican ugu habboon xaaladaha adag ee daaweynta biyaha wasakhda ah ee sifaynta saliidda.
