10% hoʻēmi no ka hoʻolaha Kalikimaka（Mana mai Dekemaba 14 – Ianuali 15）

I mea e uku ai i ke kākoʻo o nā mea kūʻai aku hou a me nā mea kūʻai aku kahiko, e hoʻomaka maoli kā mākou hui i kahi hanana hoʻēmi Kalikimaka hoʻokahi mahina i kēia lā, a e hoʻemi ʻia nā huahana āpau o kā mākou hui ma 10%. Inā makemake ʻoe, e ʻoluʻolu e kelepona mai iaʻu.

E hoʻolauna pōkole kākou i kā mākou huahana cleanwat i nā mea āpau. ʻO kā mākou huahana nui he laulā piha o nā kemika lapaʻau wai ʻino, ʻo nā huahana nui e komo pū ana me:Mea Hoʻohemo Waihoʻoluʻu Wai、Poly DADMAC、PolyacrylamideʻO ka PolyaminePolyAluminum Chloridea me nā huahana ʻē aʻe.

Hiki ke hoʻokaʻawale ʻia nā kemika hoʻomaʻemaʻe wai i ʻekolu mau ʻāpana:

1. Nā kemika mālama wai ʻino

2. Nā kemika mālama wai e kaapuni ana i ka ʻoihana

3. mea hoʻokaʻawale aila-wai

Nā hiʻohiʻona o nā kemika hoʻomaʻemaʻe wai hou

1. He wikiwiki ka wikiwiki o ka hopena, a he hapalua hola wale nō a i kekahi mau hola e mālama ai i ka wai ʻino maʻamau o ka ʻoihana.

2. He nui nā hopena i nā mea haumia organik, a he hopena maikaʻi kona i nā mea organik paʻakikī ke hoʻohaumia.

3. He maʻalahi ke kaʻina hana, he liʻiliʻi ka hoʻopukapuka kālā, he lōʻihi ke ola lawelawe, he maʻalahi ka hana a me ka mālama ʻana, kūpono ka hopena lapaʻau, a ʻoi aku ka liʻiliʻi o ka reagent micro-electrolysis i hoʻopau ʻia i ka wā o ka lapaʻau ʻana.

4. Ma hope o ka mālama ʻia ʻana o ka wai hoʻoneoneo e ka micro-electrolysis, e hoʻokumu ʻia nā iona ferrous a hao paha mua i loko o ka wai, kahi hopena coagulation maikaʻi aʻe ma mua o nā coagulants maʻamau. ʻAʻohe pono e hoʻohui i nā coagulants e like me nā paʻakai hao, a kiʻekiʻe ka helu wehe COD, a ʻaʻole ia e hoʻoulu i ka haumia lua i ka wai.

5. He hopena coagulation maikaʻi kona, hiki ke wehe pono i ka chroma a me COD, a hoʻomaikaʻi nui i ka biodegradability o ka wai hoʻoneoneo.

ʻElima mau waiwai o ka mea hana hoʻomaʻemaʻe wai mineral kūlohelohe: adsorption, ion exchange, catalytic cracking, chemical conversion, and physiological fertility. Nā pono o ka hoʻohana ʻana:

(1) ʻO ka pōmaikaʻi nui loa, hiki iā ia ke mālama i nā ʻano paʻakikī āpau e mālama, ʻoiai hoʻi nā wai ʻawahia;

(2) Hiki ke wehe ʻia kahi liʻiliʻi o nā mea lana;

(3) ʻO ka wikiwiki o ka flocculation a me ka sedimentation, ka haʻahaʻa o ka makū o ka sediment, ka nui o ka density, ka dehydration maikaʻi, a me ka maʻalahi o ke kaomi ʻana i ka kānana;

(4) He maʻalahi nā hale hana a me nā kaʻina hana hoʻomaʻemaʻe wai ʻino, maʻalahi e hana, kahi e hōʻemi nui ai i ka hoʻopukapuka kālā hoʻokahi manawa i ke kūkulu ʻana i ka papahana, a ʻaʻole kiʻekiʻe ke kumukūʻai hana;

(5) Hiki ke hoʻohana ʻia ka sludge i hana ʻia i ka mālama ʻana i ka wai ʻino ma ke ʻano he mea hoʻohuihui mea hoʻouluulu e loaʻa ai ka hopena synergistic, no ka mea, ʻo ka mea maka mineral he mea hoʻohui mea hoʻouluulu kaumaha i ka wā mua. I mea e hoʻopau loa ai i ka haumia lua.

I loko o ka ʻoihana hoʻomaʻemaʻe wai, ʻaʻole wale nā ​​ʻano lako hana hoʻomaʻemaʻe wai like ʻole i hoʻohana nui ʻia, akā hāʻawi pū nā kemika hoʻomaʻemaʻe wai i nā ʻoihana like ʻole. ʻO nā kemika hoʻomaʻemaʻe wai e komo pū me nā mea hoʻopaʻa i ka pala a me ke unahi, nā flocculants, nā mea hoʻemi, nā bactericides, nā catalysts, nā mea hoʻomaʻemaʻe, a me nā mea ʻē aʻe, nona nā hana a me nā ʻano ponoʻī.
