Atụmatụ ọgwụgwọ ụlọ ọrụ mmepụta mmiri mkpofu akwụkwọ

Isi Ihe Ndị Dị Mkpa: Ime akwụkwọ mmiri mkpofu sitere na usoro mmepụta abụọ nke ime akwụkwọ na ime akwụkwọ n'ụlọ ọrụ mmepụta akwụkwọ. Ime akwụkwọ bụ ikewapụ eriri na ihe ndị e ji osisi rụọ, mee akwụkwọ mkpofu, wee hichaa ya ọcha. Usoro a ga-emepụta nnukwu mmiri mkpofu ime akwụkwọ; ime akwụkwọ bụ ịgwakọta, ịkpụzi, pịa, ma kpọọ nkụ akwụkwọ mkpofu iji mee akwụkwọ. Usoro a na-emekwa ka mmepụta mmiri mkpofu ime akwụkwọ. Isi mmiri mkpofu a na-emepụta n'usoro ime akwụkwọ mkpofu bụ mmanya ojii na mmanya uhie, ime akwụkwọ na-emepụtakwa mmiri ọcha.

Isi ihe dị na ya 1. Nnukwu mmiri mkpofu. 2. Mmiri mkpofu nwere nnukwu ihe siri ike a kpọchiri akpọchi, ọkachasị ink, eriri, ihe na-ejupụta na ihe mgbakwunye. 3. SS, COD, BOD na ihe ndị ọzọ na-emerụ emerụ dị na mmiri mkpofu dị elu, ọdịnaya COD dị elu karịa BOD, agba ya dịkwa ọchịchịrị.

Atụmatụ ọgwụgwọ na ngwọta nsogbu.1. Usoro ọgwụgwọ Usoro ọgwụgwọ ugbu a na-ejikarị usoro ọgwụgwọ anaerobic, aerobic, physical na chemical coagulation na sedimentation combination.

Usoro ọgwụgwọ na usoro mmiri: Mgbe mmiri mkpofu batara na sistemụ mmiri mkpofu, ọ na-ebu ụzọ gafere na ebe mkpofu iji wepụ ihe ndị buru ibu, banye n'ọdọ mmiri grid maka nha nhata, banye na tankị coagulation, ma mepụta mmeghachi omume coagulation site na ịgbakwunye polyaluminum chloride na polyacrylamide. Mgbe ọ banyere na flotation, a na-ewepụ SS na akụkụ nke BOD na COD n'ime mmiri mkpofu. Ihe na-esi na flotation na-abanye na ọgwụgwọ biochemical nke anaerobic na aerobic nke ọkwa abụọ iji wepụ ọtụtụ BOD na COD n'ime mmiri. Mgbe tankị sedimentation nke abụọ gasịrị, COD na chromaticity nke mmiri mkpofu anaghị emezu ụkpụrụ emission mba. A na-eji coagulation kemịkalụ eme ihe maka ọgwụgwọ ka mma ka mmiri mkpofu wee nwee ike iru ụkpụrụ emission ma ọ bụ nwee ike iru ụkpụrụ emission.

Nsogbu na Ngwọta Ndị A Na-ahụkarị 1) COD gafere ọkọlọtọ. Mgbe ejiri ọgwụgwọ anaerobic na aerobic biochemical gwọọ mmiri mkpofu, COD nke ihe mkpofu anaghị eru ụkpụrụ mwepụta. Ngwọta: Jiri ihe na-eme ka COD dị irè nke ọma SCOD maka ọgwụgwọ. Tinye ya na mmiri n'otu oke ma meghachi omume maka nkeji iri atọ.

2) Ma chromaticity na COD gafere ọkọlọtọ ahụ Mgbe ejiri ọgwụgwọ anaerobic na aerobic biochemical gwọọ mmiri mkpofu, COD nke ihe na-ekpochapu mmiri anaghị eru ụkpụrụ mwepụta. Ngwọta: Tinye ihe na-ekpochapu mmiri nke ọma, gwakọta ya na ihe na-ekpochapu mmiri nke ọma, wee jiri polyacrylamide mee ihe maka flocculation na mmiri ozuzo, nkewa mmiri siri ike.

3) Njupụta nke ammonia nitrogen Ammonia nitrogen nke na-agbapụta mmiri agaghị emezu ihe achọrọ maka mwepụta mmiri dị ugbu a. Ngwọta: Tinye ihe na-ewepụ ammonia nitrogen, gwakọta ya ma ọ bụ mee ka ikuku dị jụụ ma gwakọta ya, wee meghachi omume maka nkeji isii. N'ime ụlọ ọrụ mmepụta akwụkwọ, ammonia nitrogen nke na-agbapụta mmiri dị ihe dị ka 40ppm, ọkọlọtọ ikuku ammonia nitrogen nke mpaghara dịkwa n'okpuru 15ppm, nke na-enweghị ike imezu ihe achọrọ maka mwepụta mmiri nke iwu nchekwa gburugburu ebe obibi kwuru.

Mmechi: Ịmepụta akwụkwọ mmiri mkpofu kwesịrị ilekwasị anya n'ịkwalite ọsọ mmiri eji eme ihe, ibelata oriri mmiri na mwepụ mmiri mkpofu, ma n'otu oge ahụ, ọ kwesịrị inyocha ụzọ dị iche iche a pụrụ ịtụkwasị obi, nke bara uru na nke na-anaghị emebi emebi nke nwere ike iji akụrụngwa bara uru na mmiri mkpofu zuru oke. Dịka ọmụmaatụ: usoro flotation nwere ike weghachite ihe siri ike fibrous na mmiri ọcha, yana ọnụego mgbake nke ruru 95%, enwere ike iji mmiri doro anya mee ihe ọzọ; usoro ọgwụgwọ mmiri mkpofu ọkụ nwere ike weghachite sodium hydroxide, sodium sulfide, sodium sulfate na nnu sodium ndị ọzọ jikọtara ya na ihe organic na mmiri ojii. Usoro ọgwụgwọ mmiri mkpofu neutralization na-agbanwe uru pH nke mmiri mkpofu; coagulation sedimentation ma ọ bụ flotation nwere ike iwepụ nnukwu ihe nke SS na mmiri mkpofu; usoro mmiri ozuzo kemịkalụ nwere ike ịgbanwe agba; usoro ọgwụgwọ bayoloji nwere ike iwepụ BOD na COD, nke dị irè karịa maka mmiri mkpofu akwụkwọ kraft. Na mgbakwunye, enwerekwa reverse osmosis, ultrafiltration, electrodialysis na usoro ọgwụgwọ mmiri mkpofu ndị ọzọ eji eme akwụkwọ na-eji n'ụlọ na mba ofesi.
