Ruwa mai guba da magani hanyoyin: da more, da mafi alheri

A mafi girma da matakin da wayewa, da more shi na samar da sharar gida. Yau, mafi gaggawa a al'amurran da suka shafi na lokacin mu ne kamar haka: "Abin da ya yi tare da su najasa yaya tsaftace Mene ne lura da najasa da sharar gida effluent ??"

Tsarkakewa na ruwa mai gudãna saukar da lambatu, - wani tsari wanda nufi ne halakar ko lalata abubuwa masu cutarwa da kuma impurities a cikin wadannan ruwayen. Wasu masana sun yi imanin cewa wannan tsari ne uniform, amma kunshi dama, saukarwa. Sauran tsarkakewa daga kowane mataki da aka ware a matsayin mai zaman kanta Hanyar. A cikin wani hali, da kyautatuwar al'amuran ruwa mai guba amfani da dama hanyoyin tsarkakewa na ruwa mai guba. Su gãfarta da taimakon:

• reagents, sunadarai.
• sedimentation da tacewa.
• electrolysis.
• hadawan abu da iskar shaka da kuma sauran physico-sinadaran canje.
• kwayoyin cuta, microbes, wasu kwayoyin.
• duk hanyoyi a lokaci daya (a cikin hãlãye).

Inji hanyoyin da ruwa mai guba magani

Basic dabaru - tacewa da kuma sedimentation. The most datti an cire ta gratings da karami iyawa sieve.

Sa'an nan kuma, tace ruwa ya wuce ta yashi tarkuna, musamman membrane da kwamin na tara najasa.

Abin gurɓatawa suna cire daga surface ta wajen man fetur, man fetur ko benzinolovushek. Magance tare da yin amfani da tace damar domin ruwa mai tsabta 75-95% na impurities, wasu daga waxanda suke recyclable.

Chemical hanyoyin da ruwa mai guba

Don haka ya kira tsaftacewa Hanyar, cikinsa da sharar gida da ruwa a cikin gabatar reactants saki impurities. Daga 25% narkewa da kuma cewa irin wannan hanyar gusar up to 75% na insoluble impurities.

Physicochemical hanyoyin da ruwa mai guba

Lokacin da wannan tsarkakewa ne aka fi amfani da:

1. Coagulation - "bonding" na lafiya barbashi a manyan tsarin.
2. Hadawan abu da iskar shaka - a dauki a wadda gurbatawa "ƙone" da mataki na reagents.
3. Sorption - sha reagents abin gurɓatawa daga ruwa mai guba.
4. Hakar - hakar ruwa da bushe abubuwa.

A amfani da adsorption, coagulation, hakar da sauran dabaru taimako cire lafiya particulate, inorganic contaminants, ko a hallaka kwayoyin abin gurɓatawa suna talauci oxidized.

Halittu ruwa mai guba da magani hanyoyin

Jigon wannan hanya ne cewa amfani halitta matakai cewa haifar da kai-tsabtace ruwa. Domin da kyautatuwar al'amuran sauran sharar gida da ruwa ne sau da yawa amfani da:

1. Biofilters - na'urorin ta hanyar abin da tace ruwa. Daga al'ada biofilters suna bambanta da gaskiyar cewa a farfajiya na ladabi anaerobic microorganisms cewa oxidize gurɓatawa.
2. Aeration - da ruwa tsarkakewa iya aiki, gina na karfafa kankare. Ga kwayoyin amoebae da ciliates lokacin rayuwarsu kayan yl inda tsaftacewa faruwa. Mushrooming a cikin laka amoebae, rotifers da sauran halittu da taimako zuwa ga ci gaba da rejuvenation na cike da laka substrate. Halittu matakai ne masu tasowa cikin sauri saboda kwayoyin bayar akai akai ciyar - sharar gida da ruwa.
3. Halittu tafkunan - mutumin da aka yi da Tsarin kare ruwa, aiki a kan manufa da na halitta kai-tsaftacewa. A tsari ya shagaltar da dukkan kwayoyin da suke zaune a cikin wani kandami.

Electrolytic hanyoyin tsabtace ruwa mai guba

A mafi kudin-tasiri su inda ruwa mai guba gurbata da wani babban adadin na karfe impurities a cikin Paint, da jan karfe masana'antu, da dai sauransu. Tsabtatawa tsari ne da za'ayi a cikin na musamman kwantena.
