Atụmatụ ọgwụgwọ na ngwọta nsogbu.1. Usoro ọgwụgwọ Usoro ọgwụgwọ ugbu a na-ejikarị anaerobic, aerobic, coagulation anụ ahụ na kemịkalụ na usoro nhazi usoro sedimentation.
Usoro ọgwụgwọ na ịgba ọsọ: Mgbe mmiri na-ekpo ọkụ na-abanye n'ime usoro ọgwụgwọ mmiri, ọ na-ebu ụzọ na-agafe ebe a na-ekpofu ahịhịa iji wepụ ihe mkpofu buru ibu, na-abanye na ọdọ mmiri grid maka nha anya, na-abanye na tankị coagulation, ma na-emepụta mmeghachi omume coagulation site n'ịgbakwunye polyaluminum chloride na polyacrylamide. Mgbe ịbanye na flotation, SS na akụkụ nke BOD na COD na mmiri mkpofu na-ewepụ. Igwe mmiri na-efegharị efegharị na-abanye na ọgwụgwọ anaerobic na aerobic nke usoro biochemical abụọ iji wepụ ọtụtụ BOD na COD n'ime mmiri. Mgbe tankị sedimentation nke abụọ gasịrị, COD na chromaticity nke mmiri mkpofu adịghị ezute ụkpụrụ ikuku nke mba. A na-eji coagulation kemịkalụ maka ọgwụgwọ emelitere ka mmiri mkpofu wee nwee ike iru ụkpụrụ a na-ewepụta ma ọ bụ nwee ike iru ụkpụrụ ikuku.
Nsogbu na ngwọta nkịtị 1) COD karịrị ọkọlọtọ. Mgbe a gwọchara mmiri mkpofu site na anaerobic na aerobic biochemical treatment, COD nke nsị anaghị emezu ụkpụrụ ikuku. Ngwọta: Jiri nnukwu arụmọrụ COD deradaration agent SCOD maka ọgwụgwọ. Tinye ya na mmiri n'otu akụkụ ma meghachi omume maka nkeji iri atọ.
2) Ma chromaticity na COD gafere ọkọlọtọ Mgbe ejiri ọgwụgwọ anaerobic na aerobic biochemical gwọọ mmiri mkpofu, COD nke ihe na-esi na mmiri anaghị erute ụkpụrụ ikuku. Ngwọta: Tinye flocculation decolorizer dị elu, jikọta ya na decolorizer dị elu, na n'ikpeazụ jiri polyacrylamide maka flocculation na mmiri ozuzo, nkewa mmiri siri ike.
3) Amonia nitrogen karịrị akarị Amonia nitrogen na-asọpụta enweghị ike iru ihe a chọrọ ugbu a. Ngwọta: Tinye amonia nitrogen wepụ, kpalie ma ọ bụ aerate na mix, na meghachi omume maka 6 nkeji. N'ebe a na-egweri akwụkwọ, ikuku amonia nitrogen dị ihe dị ka 40ppm, na ọkọlọtọ amonia nitrogen dị n'ógbè ahụ dị n'okpuru 15ppm, nke na-enweghị ike imezu ihe a chọrọ n'ikuku nke iwu nchedo gburugburu ebe obibi kwadoro.
