Iindaba

1.Ukuqokelelwa, ukulungiswa kunye nokugcinwa kweisampulu zomhlaba kumaleko wokulima

Njengesixhobo sokuhlalutya ngokuchanekileyo, i-oxygen detector idlala indima ebalulekileyo kwishishini lepetrochemical. Ayinakunceda kuphela amashishini esweni ukugxilwa kweoksijini kwindawo yemveliso ngexesha langempela, kodwa kwakhona ukuthintela ngempumelelo iingozi zokhuseleko ezibangelwa kukuxinana kweoksijini engaqhelekanga.

Kukho iintlobo ezininzi zezinto eziphilayo kugutyulo. Elinye ilindle linenqwaba, nkqu namakhulu eentlobo zezinto eziphilayo. Ukuba siqhuba uhlalutyo olunobunjani kunye nobungakanani bezinto eziphilayo kumanzi amdaka nganye nganye, kuya kudla ixesha kunye neendleko. Ngaba sinokusebenzisa isalathiso songcoliseko esinye kuphela ukumela zonke izinto eziphilayo kunye nezinye izixa kugutyulo? Leyo yi-BOD, imfuno ye-oksijini ye-biochemical.

I-Chlorophyl yeyona ndawo iphambili ye-photosynthetic pigment kwizityalo, i-algae kunye nezinye iibhaktheriya. Iyakwazi ukufunxa ukukhanya okubomvu nokuluhlaza okwesibhakabhaka kwaye ibonise ukukhanya okuluhlaza, ngoko kubonakala kuluhlaza.

Ngokukhawuleza kokufudukela ezidolophini, isikali seenkqubo zokuhambisa amanzi ezidolophini ziyaqhubeka ukwanda, kwaye impembelelo yokusebenza kwazo okuzinzile kunye nokhuseleko lomgangatho wamanzi kuphuhliso oluzinzileyo lwedolophu iye yacaca ngakumbi. Njengonxulumano olungundoqo kulawulo lokusingqongileyo kwamanzi ezidolophini, ukujonga ubulunga bamanzi okuhambisa amanzi ngobuchule kuya kudityaniswa ngokuthe ngcembe kulwakhiwo lweziseko ezingundoqo zasezidolophini kunye nenkqubo yolawulo lokusebenza. Indlela yoluvo, kunye neenzuzo zayo kwisisombululo sexeshana kunye nokugubungela indawo, ibe yindlela ephambili yobugcisa bokujongwa komgangatho wamanzi e-smart drainage, ukubonelela ngesiseko sedatha yolawulo olusulungekileyo lweenkqubo zokuhambisa amanzi ezidolophini.

Ukufuma komhlaba sisiqulatho samanzi kumaleko wekhuba lesityalo. Ayingomqondiso wembalela yomhlaba kuphela, kodwa inefuthe elimandla kwimozulu yasendle, ukungena komoya womhlaba kunye nokubola kwezondlo. Ngaxeshanye, ukufuma komhlaba ngomnye wemiba ephambili yomsebenzi wentsholongwane yomhlaba kunye nokukhula okunempilo kwezityalo. Ngoko ke, uhlolo oluchanekileyo lokunyakama komhlaba lubaluleke kakhulu, olunxulumene ngokuthe ngqo nokukhula kohlaza lwasefama.

Imisebenzi yokwembiwa kwemigodi ibalulekile xa kutsalwa izixhobo zokusebenza, kodwa ikwanika imingeni ebalulekileyo yokusingqongileyo. Ukusuka kumasuntswana othuli kunye namasuntswana ongcoliseko lomoya ukuya kwizinto ezikhutshwa kwimizi-mveliso, impembelelo emoyeni, emanzini, emhlabeni, nakwimpilo yabantu ifuna uqwalaselo olungqongqo. Ukuphumeza izixhobo eziphucukileyo ezifana nezijongi zomgangatho womoya, izichongi zerhasi eziphathwayo, kunye nezijongi zokuvuza kwerhasi kubalulekile ekuqinisekiseni izenzo zemigodi ezizinzileyo kunye nokuthotyelwa kwemithetho.

Ishishini lepetrochemical lilitye lembombo kwimveliso yamandla ehlabathi, ukunika amandla uthutho, ukuvelisa, kunye neemfuno zamandla zokuhlala. Ngokunyuka kokusetyenziswa kweoli kunye negesi, ukuqinisekisa ukhuseleko kuyo yonke indawo yokuhlola, ukucocwa, ukugcinwa, kunye neenkqubo zokuthutha kuye kwaba yinto ebalulekileyo. Ukuvuza kwerhasi, ukukhutshwa kwegesi eyityhefu, kunye neengozi ezinokutsha zenza imingcipheko ebalulekileyo, zenza iinkqubo zokubona eziphambili njengezichongi zerhasi eziphathwayo, izichongi zerhasi ezinokutsha, kunye nokuhlola umgangatho womoya izixhobo eziyimfuneko kwimisebenzi yanamhlanje yepetrochemical.

Izinto ezisibhozo zokuvavanya umhlaba kunye neendlela zibandakanya ubukhulu becala ubume bomzimba kunye neekhemikhali, umxholo wezondlo kunye neminye imiba yomhlaba.

Njengesixhobo esibalulekileyo sokubeka iliso kukhuseleko lwale mihla, izixhobo zokujonga igesi zibaluleke kakhulu kwishishini leoli negesi. Njengenxalenye ebalulekileyo yoshishino lwamandla, i-oyile kunye ne-gas industry ayihambelani kuphela nokhuseleko lwamandla kazwelonke, kodwa ihambelana ngqo nokhuseleko lobomi babasebenzi bemveliso.
