Chithandizo cha zinyalala

Kusanthula kwa Zinyalala ndi ZinyalalaChithandizo cha zinyalalaNdi njira yochotsera zinyalala zambiri kuchokera m'madzi otayidwa kapena zinyalala ndikupanga zinyalala zamadzimadzi zoyenera kutaya m'chilengedwe ndi matope. Kuti zigwire ntchito bwino, zinyalala ziyenera kunyamulidwa kupita ku malo oyeretsera pogwiritsa ntchito mapaipi ndi zomangamanga zoyenera, ndipo njira yokhayo iyenera kuyendetsedwa ndi kulamulidwa. Madzi ena otayidwa nthawi zambiri amafuna njira zosiyanasiyana komanso nthawi zina zapadera zoyeretsera. Mu njira yosavuta yoyeretsera zinyalala komanso njira zambiri zoyeretsera madzi otayidwa, zinthu zolimba nthawi zambiri zimalekanitsidwa ndi madzi mwa kukhazikika. Zimapanga mtsinje wowonjezera wa chiyero mwa kusintha pang'onopang'ono zinthu zosungunuka kukhala zinthu zolimba, nthawi zambiri biota, ndikuzikhazikitsa.

Zinyalala ndi zinyalala zamadzimadzi zochokera ku zimbudzi, mabafa, shawa, makhitchini, ndi zina zotero zomwe zimatayidwa kudzera mu ngalande. M'madera ambiri, zinyalala zimaphatikizaponso zinyalala zamadzimadzi zochokera ku mafakitale ndi malonda. M'mayiko ambiri, zinyalala zochokera ku zimbudzi zimatchedwa zinyalala zonyansa, zinyalala zochokera ku zinthu monga mabeseni, mabafa ndi makhitchini zimatchedwa madzi oundana, ndipo zinyalala za mafakitale ndi zamalonda zimatchedwa zinyalala zamalonda. Zikuchulukirachulukira m'maiko otukuka kugawa madzi apakhomo m'madzi akuda ndi akuda, pomwe madzi akuda amaloledwa kuthirira zomera kapena kubwezeretsanso zimbudzi. Zinyalala zambiri zimaphatikizaponso madzi ena pamwamba pa denga kapena malo olimba. Chifukwa chake, madzi otayidwa a m'matauni amaphatikizapo madzi otuluka m'nyumba, m'mabizinesi, ndi m'mafakitale ndipo amathanso kuphatikiza madzi otuluka m'madzi amvula.

Magawo ambiri oyesera:

· BOD (kufunika kwa okosijeni m'thupi)

·COD (Kufunika kwa Mpweya wa Chemical)

·MLSS (Mixed Liquid Suspended Solids)

· Mafuta ndi mafuta

·PH

·Kuyendetsa bwino zinthu

·Zonse zosungunuka

BOD (kufunika kwa okosijeni wa biochemical):

Kufunika kwa Oksijeni ya Biochemical, kapena BOD, ndi kuchuluka kwa mpweya wosungunuka womwe umafunika ndi zamoyo za aerobic m'madzi kuti ziwola zinthu zamoyo zomwe zili mu chitsanzo cha madzi pa kutentha kwina kwa nthawi inayake. Mawuwa amatanthauzanso njira zamankhwala zomwe zimagwiritsidwa ntchito kudziwa kuchuluka kwake. Iyi si mayeso enieni a kuchuluka, ngakhale kuti imagwiritsidwa ntchito kwambiri ngati chizindikiro cha ubwino wa madzi achilengedwe. BOD ingagwiritsidwe ntchito ngati chizindikiro choyezera kugwira ntchito bwino kwa malo oyeretsera madzi otayira. Imalembedwa ngati chinthu chodetsa chachizolowezi m'maiko ambiri.

COD (Kufunika kwa Mpweya wa Oxygen):

Mu chemistry ya zachilengedwe, mayeso a chemical oxygen demand (COD) nthawi zambiri amagwiritsidwa ntchito poyesa kuchuluka kwa mankhwala achilengedwe m'madzi. Kugwiritsa ntchito COD nthawi zambiri kumatsimikizira kuchuluka kwa zinthu zoipitsa zachilengedwe zomwe zimapezeka m'madzi apamwamba (monga nyanja ndi mitsinje) kapena m'madzi otayira, zomwe zimapangitsa COD kukhala chizindikiro chothandiza cha ubwino wa madzi. Maboma ambiri akhazikitsa malamulo okhwima pa kufunika kwakukulu kwa okosijeni wa mankhwala m'madzi otayira asanabwezeretsedwe ku chilengedwe.

Kampani yathuTayamba ntchito yokonza madzi kuyambira mu 1985 popereka mankhwala ndi mayankho a mitundu yonse ya mafakitale okonza zinyalala m'mafakitale ndi m'matauni. Ndife opanga mankhwala okonza madzi, kuphatikizapoPolyethylene glycol-PEG, Chokhuthala, Asidi wa Cyanuric, Chitosan, Wothandizira Kuchotsa Utoto wa Madzi, Poly DADMAC, Polyacrylamide, PAC, ACH, Wothandizira Kuchotsa Utoto, Wothandizira Mabakiteriya, DCDA, ndi zina zotero.
