Ọrụ nke ọtụtụ ihe ngosi anụ ahụ na kemịkalụ na aquaculture

Dị ka a na-ekwu, ịzụ azụ̀ na-ebu ụzọ ebuli mmiri, bụ́ nke na-egosi mkpa gburugburu mmiri dị na aquaculture.N'ime usoro ọmụmụ, a na-ekpebi ịdị mma nke mmiri aquaculture site n'ịchọpụta ọtụtụ ihe ngosi dịka uru pH, amonia nitrogen, nitrite nitrogen, sulfide na oxygen gbazere.Ya mere, ọ dị ezigbo mkpa ịghọta ọrụ nke ọtụtụ ihe ngosi anụ ahụ na nke kemịkal na mmiri.

1.pH

Acidity na alkalinity bụ ihe ngosi zuru oke nke na-egosipụta ogo mmiri, ọ bụkwa isi ihe na-emetụta ahụike azụ ozugbo.Omume egosila na pH nke ebe mmiri kacha mma maka uto azụ dị n'etiti 7 na 8.5.Oke dị elu ma ọ bụ dị ala ga-emetụta uto azụ na ọbụna kpatara ọnwụ azụ.Azụ na mmiri alkaline na pH dị elu karịa 9.0 ga-ata ahụhụ site na alkalosis, ma mee ka azụ ahụ zoo ọtụtụ imi, nke ga-emetụta iku ume.PH dị elu karịa 10.5 ga-akpata ọnwụ azụ ozugbo.N'ime mmiri acidic nke nwere pH dị ala karịa 5.0, ikike ibu oxygen na-ebu ọbara nke azụ na-ebelata, na-akpata hypoxia, dyspnea, mbelata oriri oriri, belata mgbaze nri, na uto ngwa ngwa.Mmiri acid na-edugakwa n'ọtụtụ ọrịa azụ nke protozoa kpatara, dị ka sporozoites na ciliates.

2.Dagbazere oxygen

Mgbasa ikuku oxygen gbazere bụ isi ihe na-egosi ogo mmiri aquaculture, na ikuku oxygen gbazere na mmiri aquaculture kwesịrị idobe na 5-8 mg / L.Enweghi ike ikuku oxygen na-agbaze nwere ike ime ka ndị isi na-ese n'elu mmiri, na n'ọnọdụ ndị siri ike, ọ ga-emetụta uto azụ ma mee ka ọnwụ nke ọdọ mmiri pan. Ịta nke ikuku oxygen na-agbaze na mmiri ahụ na-emetụta kpọmkwem ọdịnaya nke ihe ndị na-egbu egbu na mmiri ahụ.Idokwa ikuku oxygen gbazere nke ọma na ahụ mmiri nwere ike ibelata ọdịnaya nke ihe na-egbu egbu dị ka nitrite nitrogen na sulfide.Oxygen na-agbaze nke ọma n'ime mmiri nwere ike ịkwalite mgbochi nke ihe na-amụ nwa ma welie nnabata ha na gburugburu ọjọọ.

1.Nitrate nitrogen

Ọdịnaya nke nitrite nitrogen n'ime mmiri karịrị 0.1mg/L, nke ga-emerụ azụ ahụ ozugbo.Mmeghachi omume nitrification nke mmiri na-egbochi bụ kpọmkwem ihe kpatara mmepụta nitrite nitrogen.Mmeghachi omume nitrification nke mmiri nitrifying bacteria na-emetụta okpomọkụ, pH na ikuku oxygen gbazere na mmiri.Ya mere, ọdịnaya nitrite nitrogen dị na mmiri nwere njikọ chiri anya na mmiri okpomọkụ, pH na ikuku oxygen gbazere.

2. Sulfide

Nsi nke sulfide na-ezo aka na nsi nke hydrogen sulfide.Hydrogen sulfide bụ ihe na-egbu egbu nke ukwuu, itinye uche dị ala na-emetụta uto nke ihe aquaculture, na itinye uche dị elu ga-eduga ozugbo na nsị na ọnwụ nke ihe aquaculture.Mmebi nke hydrogen sulfide yiri nke nitrite, ọkachasị na-emetụta ọrụ na-ebu oxygen nke ọbara azụ, na-ebute hypoxia nke azụ.Ekwesịrị ịchịkwa ntinye nke hydrogen sulfide na mmiri aquaculture n'okpuru 0.1mg / L.

Ya mere, ịghọta nke ọma ihe ndị a na-anwale, na-eme nnwale mgbe niile, na ime usoro kwekọrọ n'oge kwesịrị ekwesị nwere ike ime ka ọnụọgụ azụ na oporo dịkwuo mma ma belata ọnụ ahịa ịzụ nwa.
