Uyini Ithangi Lokulinganisa? Isivikelo Esibalulekile Sengqalasizinda Yamanzi Angcolile
Imifudlana yamanzi angcolile ezimbonini nawamasipala ayikaze ifane. Izindawo zokukhiqiza zisebenza ngamaqoqo, izishintshi ziyashintsha, futhi izivunguvungu zibangela ukugcwala okungazelelwe kwamasipala. Uma indawo yokuhlanza izama ukucubungula lezi 'zinqwaba' ezingaqaguleki zikadoti ngqo, imishini engezansi izohluleka ngokushesha.
Ithangi lokulinganisa (elivame ukubizwa ngokuthi i-EQ tank noma i-equalization basin) iyunithi ekhethekile yokugcina eklanyelwe ukuqoqa ukungena okuhlukahlukene okuyimpahla eluhlaza futhi ikukhulule ngezinga elizinzile, elilawulekayo. Isebenza njengesixhumi esikhulu sokumunca ukushaqeka kwe-hydraulic namakhemikhali, iqinisekisa ukuthi izigaba ezilandelayo zokucubungula ngokomzimba, amakhemikhali, nezinto eziphilayo zisebenza ngaphansi kwezimo ezinzile, ezingaguquki.
The Dual Balancing Vectors of Equalization
To appreciate why an equalization basin is an essential component of a wastewater treatment plant (WWTP), it helps to examine the two distinct ways it balances incoming waste streams:
1. Hydraulic (Flow) Equalization
Ukuhlukahluka kokugeleza kwemini (izikhathi eziphakeme nezephansi zansuku zonke) kubeka ingcindezi enkulu emishinini yokuhlanza. Ngezikhathi zokusetshenziswa okuphezulu, ukugijima kwamanzi okungazelelwe kungagcwalisa amachamuzi okuqala ngokwe-hydraulic, kunciphise izikhathi zokugcina amanzi futhi kuphushe izinto ezimisiwe phezu kwemisele yokukhipha amanzi. Ithangi le-EQ lisebenza njengendawo yokugcina ngezikhathi zalokhu kunyuka okukhulu komthamo, ligcine amanzi angeziwe futhi liwakhiphe kancane ngezinga elilinganiselwe lokugeleza kusetshenziswa amaphampu e-variable frequency drive (VFD).
2. Ukulinganisa Ukwakheka (Composition)
Ukwakheka kwamanzi angcolile kuyashintsha umzuzu nomzuzu. Ukunyuka kwamandla emfucuza—okufana nokulahlwa okungazelelwe kwama-asidi agxilile, izihlanzi ezi-alkaline, noma izinto eziphilayo eziminyene ezine-Biochemical Oxygen Demand (BOD) ephezulu kakhulu—kungacekela phansi izinhlelo zokuhlanza ezisezansi. Ngaphakathi ethangini le-EQ, lezi zingxube ezigxilile kakhulu ziyahlanjululwa futhi zixutshwe kahle namanzi okugeza anamandla aphansi, kwakheke ingxube efanayo, ebikezelwayo.
Ukuqhathanisa Ukumiswa Kwezinhlelo Zokulinganisa
Ngokuya ngezithiyo zendawo yesikhungo kanye nokuhlukahluka okuthile kwamanzi angcolile, onjiniyela basebenzisa izinhlelo zokulinganisa ngendlela eyodwa kwezimbili eziyinhloko, noma bakhethe ukuyigwema ngokuphelele ngengozi ephezulu yokusebenza.
I-Vector Yokusebenza | Ukulinganisa Okungaphakathi Kolayini | Ukulinganisa Okungaphandle Kolayini (Eceleni) | Ukuphakela Okuqondile (Akukho Ukulinganisa) |
Indlela Yokugeleza | Umsakwane Ophelele. U-100% wamanzi angcolile angenayo adlula ethangini. | Umsakwane Wokudlula. Ukugeleza okuphezulu okweqile kuphela okuphambukiselwa ethangini. | Umfula Oqondile. Amanzi angcolile ageleza ngqo ezigabeni eziyisisekelo/zesibili. |
Ukuhlanganiswa Kwezakhiwo | Okuphezulu kakhulu. Inikeza ukuhlanganiswa okuhle kakhulu kwe-pH, izinga lokushisa, nezinto eziphilayo. | Okumaphakathi. Ihlanganisa amagagasi aphezulu, kodwa ukugeleza okujwayelekile kudlula ukuxuba ngokuphelele. | Zero. Amasistimu asezansi avezwe ngokugcwele emazingeni aphezulu amakhemikhali angalungisiwe. |
Umkhondo & Umthamo Wethangi | Mkhulu. Udinga umthamo omkhulu wokugcina ukuze uthwebule konke ukushintshashintsha kokugeleza kwansuku zonke. | Incane. Idinga amandla ethangi amancane ngoba igcina kuphela umthamo wokugcwala okungazelelwe. | Akukho. Ayidingi indawo ekhethekile, kodwa ikhulisa kakhulu ubukhulu bemishini elandelayo. |
Inzuzo Eyinhloko | Ukuzinza okuphelele kwenqubo; ikhulisa ukunemba kokulinganisa kwamakhemikhali okulandelayo. | Iyonga kakhulu izindleko; inciphisa izindleko zokuqala zengqalasizinda (CAPEX). | Izindleko eziphansi kakhulu zengqalasizinda yokuqala. |
Ifaneleka Kakhulu | Izimboni ezikhiqiza ngezigaba ezinamakhemikhali nezinto eziphilayo eziguquguquka kakhulu. | Izinhlelo zomasipala ezinokugcwala kwamanzi emvula noma ukukhuphuka kwansuku zonke okubikezelwayo okwesikhashana. | Izikhungo ezincane ezinokugeleza okuqhubekayo ezinamanzi angcolile azinzile, angaguquki. |
Ukuvikelwa Okubalulekile Okungezansi Okunikezwa Ithangi le-EQ
Ithangi lokulinganisa elixutshwe kahle, eliphethwe kahle lisebenza njengesihlangu sokuvikela ezigabeni eziyinhloko zokwelapha ezingezansi:
● Ukuvikela Izinhlelo Zebhayoloji: Izinqubo zebhayoloji ezingezona eziyinhloko (ezinjenge-activated sludge noma i-Moving Bed Biofilm Reactors [MBBR]) zincike emakoloni amagciwane aphilayo ukuze adle imfucumfucu ephilayo. Lawa magciwane azwela kakhulu ekushintsheni okusheshayo kwe-pH, ekushintsheni okungazelelwe kwezinga lokushisa, nokushaqeka okunobuthi okuphilayo. Ithangi le-EQ livimbela lokhu kushintshashintsha, ligcina isilinganiso esizinzile sokudla kuya kumagciwane ($F/M$) ukuze i-biomass iphile.
● Ukuthuthukisa Amayunithi e-Phys-Chem & DAF: Izinhlelo zamakhemikhali ezibonakalayo, ezifana ne-Dissolved Air Flotation (DAF), zincike ekulinganiseni amakhemikhali ngokunemba okukhulu (ama-coagulants nama-flocculants). Ngenxa yokuthi ithangi lokulinganisa linikeza ukugxila okufanayo, imijikelezo yokulinganisa amakhemikhali ingasebenza ngokunembile ngaphandle kokulungiswa njalo, inciphisa izindleko eziphelele zamakhemikhali.
● Ukuvimbela Ukuhlala Phansi Namaphunga: Ukuze kuvinjelwe izinto eziqinile ukuthi zingahlali phansi nokugcina amanzi engaphenduki i-anaerobic—okudala igesi eyingozi kakhulu nenuka kabi i-hydrogen sulfide ($H_2S$)—amathangi e-EQ afakwa izinto zokuxuba ezinamandla ezingaphansi kwamanzi noma izinhlelo zokufaka umoya ezihlakaza amabhamuza amakhulu. Lokhu kuxuba okuqhubekayo kugcina izinto eziqinile zintanta futhi kugcina amazinga abalulekile we-oksijini encibilikile.
Imibuzo Evame Ukubuzwa (FAQ)
Q: Ingabe ithangi lokulinganisa libalwa njengesigaba sokwelapha?
A: Ngokuyinhloko, cha. Nakuba inani elincane lokubola kwemvelo kanye nokulinganiswa kwe-pH okungenzi lutho kwenzeka ngenxa yokuxuba okuqhubekayo, ithangi lokulinganisa ngokobuchwepheshe lihlukaniswa njengenqubo yomzimba eyodwa. Umsebenzi walo ukulungisa nokuzinzisa amanzi angcolile ukuze alungiselele ukwelashwa, kunokuba asuse ukungcola ngokwawo.
Q: Onjiniyela babala kanjani umthamo odingekayo wethangi le-EQ?
A: Ubukhulu bunqunywa ngokudwetshwa kwe-mass mass-balance hydrograph phakathi nomjikelezo wamahora angu-24. Onjiniyela bafaka imephu yomthamo oqongelelwe oqondene nezinga lokukhipha elilandelanayo, elingaguquki. Umehluko omkhulu phakathi kwalezi zingwegwe ezimbili umele umthamo wokusebenza odingekayo, lapho kufakwa khona isici sokuphepha esingu-15% kuya ku-20% se-freeboard ukuze kuhlangatshezwane ne-foam engalindelekile, ukunqwabelana kwe-sludge, noma ukuphakama okuphuthumayo.
Q: Yiziphi izinselelo eziyinhloko zokugcina isikhwama sokulinganisa?
A: Izinselelo ezivame kakhulu zokusebenza zihlanganisa ukunqwabelana kwezinto eziqinile ezindaweni "ezifile" zethangi ngenxa yokuxubana okunganele, ukuguga kwemishini emaphampanini angaphansi kwamanzi, kanye nokugqwala okukhulu okuvela ekuphatheni imfucuza yamakhemikhali eluhlaza. Ngenxa yalesi sizathu, izikhungo zesimanje ziya zisebenzisa amathangi ahlanganisiwe amelana nokugqwala esikhundleni sikakhonkolo wendabuko, ovame ukuqhekeka futhi ewohloka ngesikhathi.
