ʻO ke kumu hana o ka mīkini hoʻohui wai ʻino

1: Electrolysis: ʻO ka hoʻohana ʻana i ke ʻano o ka electrolysis, i hiki ai i nā mea ʻino i loko o ka wai ʻōpala mua ma o ke kaʻina hana electrolytic ma nā pole Yang a me Yin i ka oxidation a me ka hoʻohaʻahaʻa ʻana i ka hoʻololi ʻana i loko o ka wai i hoʻokaʻawale ʻia, i mea e hoʻokaʻawale a wehe. mea ino. Hoʻohana nui ʻia no ka mālama ʻana i ka wai ʻōpala i loko o ka chromium a me ka wai ʻino cyanide, akā hoʻohana pū ʻia e wehe i nā ion metala kaumaha, ka aila a me nā mea paʻa i hoʻopaʻa ʻia i ka wai ʻino; Hiki iā ia ke condense a adsorb i nā molekala kala i loko o ka colloidal state a i ʻole i hoʻoheheʻe ʻia i loko o ka wai ʻino, a hiki i ka hana REDOX ke hoʻopau i ka hui kala a loaʻa ka hopena decolorization. i kēia loulou.3: PAC dosing: ʻo ia hoʻi, ka polyaluminum chloride, he coagulant polymer inorganic hou, kahi kiʻekiʻe o ka neutralization uila a me ka hopena bridging ma nā colloids a me nā ʻāpana i loko o ka wai, a hiki ke hoʻoneʻe ikaika i nā mea micro-toxic a me nā metala kaumaha. ions.4: PAM dosing: ʻo ia hoʻi, polyacrylamide, loaʻa ka flocculation maikaʻi, hiki ke hoʻemi i ke kūpaʻa friction ma waena o nā wai. ʻO ka hoʻohana pū ʻana o PAC a me PAM e hoʻopau i ka PAC i ka hoʻopau ʻana i ka hoʻokaʻawale ʻana o ka charge/colloid instability e hana i kahi floc liʻiliʻi, a hoʻonui hou i ka floc volume e kūpono i ka ua piha. ʻO nā ʻōhū maikaʻi i loko o ka wai, no laila ua hoʻopili ʻia ka ea i ka floc insoluble ma hope o ka hoʻohui ʻana i ka flocculation lāʻau lapaʻau i ke ʻano o nā puʻupuʻu liʻiliʻi liʻiliʻi i hoʻopuehu nui ʻia, e hopena i kahi mokuʻāina ʻoi aku ka liʻiliʻi ma mua o ka wai, e hoʻohana ana i ke kumu o ka buoyancy e lana ma luna o ka wai. ili, i mea e hiki ai i ka hoʻokaʻawale paʻa-wai, a laila, ʻokiʻoki i ka scum ma o ka scraper i ka slag pahu, a hope kahe i ka sludge tank.6: Multi-media kānana papa: ① Quartz one kānana mea e kānana i ka wai me kiʻekiʻe turbidity ma o kekahi mānoanoa o granular a non-granular quartz one, e hoʻopaʻa pono a wehe i ka mea i hoʻokuʻu ʻia, nā mea ola, nā ʻāpana colloid, microorganisms, chlorine, ʻala a me kekahi mau ion metala kaumaha i loko o ka wai; ʻO ka kānana kalapona i hoʻāla ʻia ke kaʻina hana o ka intercepting i nā mea haumia i loko o ke kūlana wai i hoʻokuʻu ʻia, a hoʻopiha ʻia ka mea i hoʻokuʻu ʻia me ke āpau ma waena o ke kalapona hoʻāla.7. ʻO ka loko wai maʻemaʻe: No ka liʻiliʻi o ka kahe wai ma hope o ka papa kānana multi-media, ua hoʻomaikaʻi maikaʻi ʻia ka SS index o ka wai kānana, a pono e mālama ʻia i kēia loulou.

8: Membrane filtration nenoaiu: maheleia i elua mau papa, o ia hollow fiber membrane a me RO reverse osmosis membrane, ka hoʻohana 'ana i ke kiʻekiʻe kiʻekiʻe puʻupuʻu e like me ka hoʻoikaika 'ana e intercept like ole inorganic ion, colloidal mea a me macromolecular solutes i loko o ka wai, i mea e loaa. he hoʻokuʻu maʻamau wai ʻupena. I ka manawa like, hoʻihoʻi ʻia ka wai hoʻokaʻawale osmosis i ka pahu electrolytic no ka mālama hou ʻana.
