Usoro mkpochapụ maka mmiri Aquaculture

Usoro ịgbasa mmiri maka mmiri aquaculture na-agụnye ọtụtụ ụzọ dị ka ultraviolet (UV) sterilization, ozone disinfection, na ọgwụ kemịkalụ. Taa, anyị ga-ewebata UV na ozone dị ka ụzọ abụọ maka igba ogwu na disinfection. Edemede a na-enyocha ụzọ ndị a nke ọma site n'echiche nke usoro ịmụ nwa na njirimara.

Mgbochi UV

Ụkpụrụ nke ịgba ọgwụ mgbochi UV gụnyere nnabata nke ume ọkụ UV site na microbial nucleic acid, gụnyere ribonucleic acid (RNA) na deoxyribonucleic acid (DNA). Mmụba nke a na-agbanwe ọrụ ndụ ha, na-eduga na nbibi nke njikọ na agbụ nke nucleic acid, njikọta n'ime acids nucleic, na imepụta fotoproducts, si otú a na-egbochi mmeghari microbial na ịkpata mmebi na-egbu egbu. UV ọkụ na-categorized n'ime UVA (315 ~ 400nm), UVB (280 ~ 315nm), UVC (200 ~ 280nm), na agụụ UV (100 ~ 200nm). N'ime ndị a, UVA na UVB nwere ike iru elu ụwa site na oyi akwa ozone na mkpuchi igwe ojii. UVC, nke a maara dị ka teknụzụ na-ekpochapụ UV-C, na-egosipụta mmetụta ọgwụ mgbochi siri ike.

Ịdị irè nke ịgba ọgwụ mgbochi UV na-adabere na ọnụọgụ nke radieshon UV natara site na microorganisms, yana ihe ndị dị ka ike mmepụta UV, ụdị oriọna, ike ọkụ, na oge ojiji.

Ozone Disinfection

Ozone bụ oxidant siri ike, na usoro igba ogwu ya na-agụnye mmeghachi omume oxidation biochemical. Ozone sterilization na-arụ ọrụ site n'ụdị atọ: (1) oxidizing na decomposing enzymes n'ime nje bacteria na-eji glucose, si otú deactivating bacteria; (2) soro nje bacteria na nje na-emekọrịta ihe ozugbo, na-akpaghasị metabolism microbial na-akpata ọnwụ; na (3) ịbanye n'ime sel site na akpụkpọ anụ sel, na-eme ihe na lipoproteins dị n'èzí na lipopolysaccharides dị n'ime, na-eduga na mgbasa nje na ọnwụ. Ozone sterilization bụ sara mbara-ụdịdị dị iche iche na lytic, n'ụzọ dị irè na-ewepụ nje bacteria, spores, nje, fungi, na ọbụna nwere ike ibibi botulinum toxin. Ọzọkwa, ozone na-aghọ ngwa ngwa n'ime ikuku oxygen ma ọ bụ otu ikuku oxygen n'ihi nkwụsi ike ya adịghị mma. Otu mkpụrụ ikuku oxygen nwere ike imegharị ka ọ bụrụ ikuku oxygen, na-eme ka ikuku oxygen na-eme ka mmiri na-ekpo ọkụ na-ahapụghị ihe ọ bụla na-egbu egbu. Ya mere, a na-ewere ozone dị ka ihe na-adịghị mma na-adịghị emerụ ahụ.
