I roto i te hanga ahumahi. Ko ngā wira hurihuri, hei wāhanga nui o tana hangarau maimoatanga mata, he mea nui hei whakarei ake i te ataahua, te roa me te ātete ki te waikura o te hua. Ko te whakapūmau hei maimoatanga mata noa. He whānuitia te whakamahinga i roto i te maimoatanga mata o ngā koranu whakarewa. Ka whakamāramahia e tēnei tuhinga ētahi tikanga noa mō te whakapūmau i ngā wira hurihuri, tae atu ki te whakapūmau cyanide, te whakapūmau zincate, te whakapūmau chloride, me te whakapūmau sulfate. I hangaia hei whakarato i tētahi tohutoro hangarau whānui ki ngā kaipānui.
1, te whakapūmautanga o te cyanide
Ko te whakapūmau i te cyanide, nā tōna kaha horapa nui me te kounga pai o te whakakikorua. I mua he tūranga nui tōna i roto i te umanga whakakikorua hiko. Heoi, nā te tino paitini o te cyanide me te tūponotanga o te riri ki te taiao, he tino herea tōna whakamahinga. Heoi anō, ko te whanaketanga o ngā tukanga whakakikorua iti-cyanide (microcyanide). Ka taea ai te whakamana i te kounga o te hua me te whakaiti i ngā tūponotanga taiao. I raro i te tukanga whakakikorua cyanide, he tino pai te kounga o te hua i muri i te whakakikorua i te wāhanga taputapu o te mīhini whakarewa. Ina koa i muri i te whakakorenga o te whakakikorua tae, ka noho kanapa tonu ngā Tae mō te wā roa.
2, ngā kupu me ngā ariā e pā ana ki te whakarewa konutea konutea
Ko te tukanga whakapūmau konutea he huarahi pai ki te taiao hei whakakapi i te whakapūmau cyanide. I tēnei wā, kua wehea te nuinga ki te raupapa "DPE" o te Whare Wānanga Tiaki Rauemi o Wuhan me te raupapa "DE" o te Whare Wānanga o Guangdian. He mea whakapūmau konutea ngā mea e rua me ngā tāpiringa kawakore. He āhuatanga tōna o te hanganga whatu poutū o te whakakikorua, he ātete pai ki te waikura, ā, he pai mō te whakapūmau tae. Ko tōna hanganga noa ko te NaOH, ZnO, me ngā tāpiringa motuhake. Hei tauira, ko te whakakotahitanga o te "DPE-II" me te ethanolamine. Me tino whakahaere tēnei tukanga i te hanganga o te otinga whakakikorua me ngā āhuatanga o te tukanga, pērā i te pH, te pāmahana, me te mātotoru o te iahiko, hei whakarite i te kounga o te whakakikorua. I muri i te wehenga atu o te hua i te tāke, me haere i roto i te raupapa o ngā mahi tukatuka-muri pērā i te horoi, te whakakanapa, te whakakore me te whakamaroke, kia pai ai ngā hua.
3, te whakapūmautanga o te konukōre
He whānuitia te whakamahinga o te tukanga whakapūkara konukōre i roto i te umanga whakakikorua taputapu whakarewa. Neke atu i te 40% te ōrau. He rite te āhua o te tukanga kua pāngia (kikorangi-mā, hiriwa-mā rānei) ki te whakakikorua konukōre. Ā, he iti te utu. Ko ngā whakatakotoranga noa mō te whakapūkara konukōre ko te KCl, ZnCl_2, H_3BO_3 (pūmau), me ngā mea whakamārama motuhake. He tino pai te tukanga mō te pāngia mā (kikorangi-mā, hiriwa-mā). I roto i ēnei, ko te pāngia hiriwa-mā nā te mea he pumau te tae. He pai ake te nuinga hei whiringa tuatahi. Heoi, he mea tika kia mōhio ko ngā paninga whakapūkara konukōre, ina pāngia ki te hau mō ngā wā roa, ka rerekē te tae o te kiriuhi. Ka pā ki te āhua me te ātete ki te waikura o te hua. Nō reira, i roto i te mahi, me mahi i ngā mahi tika hei ārai i te rerekētanga o te tae.
4, te whakapūmautanga o te whanariki
Ko te tukanga whakapūmau i te whanariki, me tōna utu iti me te pai mō te whakakikorua tonu (hei tauira, te waea, te rīpene, me ētahi atu). He wāhi i roto i te umanga whakakikorua hiko. Ko ngā whakatakotoranga noa mō tēnei tukanga ko te ZnSO_4, te H_3BO_3, me ngā mea whakamārama motuhake. Ko te uara pH o te whakapūmau i te whanariki ka whakahaerehia i waenga i te 4.5 me te 5.5. Mā te whakarerekē i te hanganga o te otinga whakakikorua me ngā āhuatanga o te tukanga, ka taea te whiwhi i te paninga A me te ātete waikura me te kanapa pai. Heoi. Ki te whakatauritea ki ētahi atu tukanga whakapūmau, tera pea he iti ake te kanapa me te ōrite o te paninga i te whakapūmau i te whanariki.
ngā kōrero whakamutunga
Hei whakarāpopototanga. He maha ngā tikanga whakapūmau mō ngā mīhini whakarewa. He rerekē ngā painga me te whānuitanga o te whakamahinga o ia tikanga. I roto i te mahi. Me ahu mai i te taiao whakamahinga me ngā whakaritenga mahi motuhake a te mīhini whakarewa. Kōwhiria te tukanga whakapūmau tika. I tēnei wā. Me te kaha haere o ngā ture taiao me ngā whanaketanga o te hangarau whakakikorua, ka noho te tukanga whakapūmau hoa taiao, whai hua, me te utu-whai hua hei ia o ngā whanaketanga ā muri ake nei.
