Melemele Solid Polymerized Ferric Sulfate Pauda

ʻO ka wehewehe pōkole:

Introduction: ʻO SPFS kahi paʻa amorphous māmā melemele, hiki ke hoʻoheheʻe ʻia i ka wai.ʻO 10% (ma ke kaumaha) o ka wai wai he ʻulaʻula ʻulaʻula ʻulaʻula ʻulaʻula me ka hygroscopicity.Hoʻohana nui ʻia ka polyferric sulfate i ka hoʻomaʻemaʻe ʻana i ka wai inu, ka wai ʻoihana, nā ʻano wai ʻona ʻoihana like ʻole, ka wai hoʻoneʻe kūlanakauhale, ka hoʻoheheʻe ʻana o ka sludge a pēlā aku.

ʻO ka polyferric sulfate ka hana hoʻomaʻemaʻe wai maikaʻi loa, no laila makemake ʻia e ka ʻoihana mālama wai.Ua hoʻohana nui ʻia i loko o nā ʻano wai ʻino ʻenehana a me ka mālama ʻana i nā kaona.Hiki iā ia ke wehe pono i nā mea paʻa i hoʻopaʻa ʻia, nā mea kūlohelohe, sulfide, nitrite, colloid a me nā ion metala i loko o ka wai.ʻOi aku ka ʻoi aku o ka corrosive o ka effluent o nā mea hana hoʻoheheʻe wai ma luna o ka ferrous sulfate ma mua o nā mea hana hoʻomaʻemaʻe wai [2].

Kiʻi Huahana

Solid Polyferric Sulfate1

Nā kikoʻī huahana

1. ʻAʻole ʻona ka huahana, ʻaʻohe pōʻino, palekana a hilinaʻi.E like me nā ʻōlelo o ke kaʻina loiloi loiloi toxicological palekana o Kina, ua hoʻokō ʻia ka hoʻāʻo ʻana o ka polyferric sulfate (SPFS a i ʻole PFS), ʻo ia hoʻi, ʻo nā hopena hōʻike LD50 koʻikoʻi nā huahana non-toxic;ʻO ka hoʻāʻo kumulative toxicity, subacute toxicity test, micronucleus test a me teratogenic test i hōʻike i nā hopena maikaʻi ʻole, ka mea i hōʻoia i ka huahana (PFS) ʻaʻole ia he mea ʻawaʻawa, a ʻo ka mea ferrous sulfate i hoʻohana ʻia i ka hana i hoʻokō i nā koi o ke kūlana aupuni gb10531- 89 no ka wai inu.

2. Ka hoʻoili ʻana o ka wai me ka hao ʻole a me nā koena hao.ʻO ka maʻiʻo hao o ka wai ma mua o ka kānana ʻana he 0.28mg/l (ʻo 0.3mg/l ka mea hao i loko o ke code hygienic national no ka wai inu), a ʻo ka mea hao o ka effluent kānana ʻaʻole ia ma mua o 0.05mg/l;A he kala ʻole ka wai kānana.

3. Ma ke kaʻina hana coagulation o ka hoʻomaʻemaʻe wai inu, hōʻike ka huahana: wikiwiki coagulation wikiwiki, coarse alum hana, wikiwiki sedimentation a me haʻahaʻa effluent turbidity;Inā ʻo ka awelika turbidity o ka wai maka he 33 NTU, (ʻo ka awelika wai wela he 18.7 ℃), ʻo ka awelika o ka PFS he 37.5 mg / L, a ʻo ka awelika turbidity o ka wai e kānana ʻia he 0.97 NTU;ʻO ka awelika turbidity o ka wai kānana he 0.085ntu (ma ka hoʻohālikelike ʻana, ke hoʻohui ʻia ka alumini sulfate no ka hoʻāʻo like ʻana, ʻo ka awelika turbidity o ka wai e kānana ʻia ʻo 1.1ntu; ʻo ka awelika turbidity o ka wai kānana he 0.29ntu).

Nā hiʻohiʻona noi

Hoʻohālikelike ʻia me nā flocculants inorganic ʻē aʻe, loaʻa iā ia nā hiʻohiʻona penei:

1. Hou, kūlana kiʻekiʻe a kiʻekiʻe-efficiency hao paʻakai inorganic polymer flocculant;

2. ʻO ka hana coagulation maikaʻi loa, ka alum paʻa a me ka wikiwiki hoʻoholo wikiwiki;

3. ʻO ka hopena hoʻomaʻemaʻe wai maikaʻi, maikaʻi ka wai maikaʻi, ʻaʻohe mea ʻino e like me ka aluminika, chlorine a me nā ion metala koʻikoʻi, ʻaʻohe hoʻololi wai o nā ion hao, non-toxic,

ʻAʻole pōʻino, palekana a hilinaʻi;

4. Nā hopena koʻikoʻi o ka wehe ʻana i ka turbidity, decolorization, deoiling, dehydration, sterilization, deodorization, algae removal, COD, BOD a me nā ion metala kaumaha i ka wai;

5. E hoʻololi i ka laulā o ka waiwai pH o ke kino wai, 4-11, a ʻo ka laulā maikaʻi loa o ka waiwai pH ʻo 6-9.He liʻiliʻi ka ʻano like ʻole o ka waiwai pH a me ka nui o ka alkalinity o ka wai maka ma hope o ka hoʻomaʻemaʻe ʻana,

ʻOi aku ka corrosive i nā lako lapaʻau;

6. ʻO ka hopena hoʻomaʻemaʻe o ka micro polluted, algae i loko, haʻahaʻa haʻahaʻa a me ka haʻahaʻa turbidity wai maka he mea kupaianaha, ʻoi aku ka nui o ka wai maka wai;

7. He liʻiliʻi ka dosage, haʻahaʻa ke kumukūʻai, a hiki ke mālama ʻia ke kumukūʻai lapaʻau e 20% - 50%.
