Te tātaritanga whaihua o te tono i roto i te maimoatanga waipara ahumahi
1. Whakataki taketake
Ko te parahanga konganuku taumaha e pā ana ki te parahanga taiao e puta mai ana i ngā konganuku taumaha, i ō rātou matū rānei. Ko te nuinga o te wā e puta mai ana i ngā āhuatanga tangata pēnei i te keri maina, te tukunga hau para, te whakamakuku waipara me te whakamahinga o ngā hua konganuku taumaha. Hei tauira, ko te mate wai me te mate mamae i Hapani e puta mai ana i te parahanga mercury me te parahanga cadmium. Ko te nui o te kino e whakawhirinaki ana ki te kukū me te āhua matū o ngā konganuku taumaha i roto i te taiao, te kai me ngā rauropi. Ko te nuinga o te wā e kitea ana te parahanga konganuku taumaha i roto i te parahanga wai, ā, ko tētahi wāhanga o taua mea kei roto i te hau me te para totoka.
Ko ngā konganuku taumaha e pā ana ki ngā konganuku he nui ake te taumaha (kiato) i te 4, i te 5 rānei, ā, e 45 pea ngā momo konganuku, pērā i te parahi, te mata, te konutea, te rino, te taimana, te nikara, te vanadium, te silicon, te pātene, te taitīnamu, te manganese, te cadmium, te mercury, te tungsten, te molybdenum, te koura, te hiriwa, me ētahi atu. Ahakoa he huānga iti te manganese, te parahi, te konutea me ētahi atu konganuku taumaha e hiahiatia ana mō ngā mahi ora, ko te nuinga o ngā konganuku taumaha pērā i te mercury, te mata, te cadmium, kāore e hiahiatia mō ngā mahi ora, ā, ko ngā konganuku taumaha katoa i runga ake i tētahi kukū he paitini ki te tinana tangata.
Ko ngā konganuku taumaha kei roto i te taiao i roto i ngā kukū tūturu. Heoi, nā te pikinga ake o te whakamahinga, te whakarewa, te tukatuka me te hanga arumoni o ngā konganuku taumaha e te tangata, he maha ngā konganuku taumaha pēnei i te mata, te mercury, te cadmium, te cobalt, me ētahi atu e uru ana ki te hau, ki te wai, me te oneone. Ka puta he parahanga nui ki te taiao. Ka noho tonu, ka kohia, ka heke ngā konganuku taumaha i roto i ngā āhua matū rerekē, i ngā momo matū rānei i muri i te urunga ki te taiao, ki te pūnaha rauropi rānei, ka puta he kino. Hei tauira, ka kohia pea ngā konganuku taumaha e tukuna ana me te wai para ki roto i te rimurimu me te paru o raro ahakoa he iti te kukū, ā, ka piri ki te mata o ngā ika me ngā kaimoana, ka hua ake he kukū mekameka kai, ka puta ai te parahanga. Hei tauira, ko ngā mate wai i Hapani ka puta mai i te mercury i roto i te wai para e tukuna ana mai i te umanga hanga houra kaustiki, ka hurihia hei mercury waro mā te mahi koiora; ko tētahi atu tauira ko te mamae, e puta mai ana i te cadmium e tukuna ana mai i te umanga whakarewa konutea me te umanga whakakikorua hiko cadmium. Ki. Ka uru te mata e tukuna ana mai i te hauā o ngā motuka ki te taiao mā te horapa o te hau me ētahi atu tukanga, ka hua ake he pikinga nui o te kukū mata o te mata o nāianei, ka hua ake te mimiti o te mata i roto i ngā tāngata o ēnei rā tata ki te 100 ngā wā teitei ake i tō ngā tāngata taketake, ā, ka kino hoki ki te hauora o te tangata.
Ka taea e te matū rongoā wai matūriki-whero te taunekeneke tere me ngā momo katote konganuku taumaha i roto i te wai para i te pāmahana rūma, pērā i te Hg+, Cd2+, Cu2+, Pb2+, Mn2+, Ni2+, Zn2+, Cr3+, me ētahi atu. Ka tauhohe hei hanga tote whakauru kore-rewa-wai me te tere tango neke atu i te 99%. He watea, he māmā hoki te tikanga rongoā, he iti te utu, he whakamiharo te pānga, he iti te nui o te paru, he pumau, kāore he paitini, ā, kāore he parahanga tuarua. Ka taea te whakamahi whānui i roto i te rongoā wai para i roto i te umanga hiko, te keri me te whakarewa, te umanga tukatuka konganuku, te tango whanariki i ngā tipu hiko me ētahi atu umanga. Awhe pH e tika ana: 2-7.
2. Mara tono hua
He tino whai hua tēnei tango i ngā katote konganuku taumaha, ā, he whānuitia ngā whakamahinga. Ka taea te whakamahi mō te nuinga o ngā wai para kei roto ngā katote konganuku taumaha.
3. Te tikanga whakamahi me te rere o te tukanga noa
1. Me pēhea te whakamahi
1. Tāpirihia, ka whakaohokia
① Tāpirihia te kaihoko maimoatanga wai whakarewa taumaha polymer tika ki te wai para kei roto i te whakarewa taumaha katote, ka tere te tauhohenga, ko te tikanga pai ko te whakaoho i ia 10 meneti;
②Mō ngā kukū konganuku taumaha kāore i te tino mārama i roto i te wai para, me whakamahi i ngā whakamātautau taiwhanga hei whakatau i te nui o te konganuku taumaha i tāpirihia.
③Mō te maimoatanga o te wai para kei roto ngā iona konganuku taumaha me ngā kukū rerekē, ka taea te whakahaere aunoa i te nui o ngā rauemi mata e tāpirihia ana e te ORP
2. Ngā taputapu me ngā tukanga hangarau noa
1. Whakamaoritia te wai i mua 2. Hei whiwhi i te PH=2-7, tāpirihia te waikawa, te kawakore rānei mā te kaiwhakahaere PH 3. Whakahaerehia te nui o ngā rauemi mata e tāpirihia ana mā te kaiwhakahaere redox 4. Flocculant (pāhare pākawa konumohe whanariki) 5. Te wā noho o te tāke whakaoho 10min 76, te wā pupuri o te tāke whakahiato 10min 7, te tāke whakatōtō pereti piki 8, te paru 9, te puna 10, te tātari 121, te whakahaere pH whakamutunga o te puna waikeri 12, te wai tuku
4. Te tātari i ngā painga ōhanga
Hei tauira, ko te wai para hiko he wai para whakarewa taumaha noa iho, i tēnei umanga anake, ka nui ngā painga pāpori me te ōhanga ka puta mai i ngā kamupene tono. Ko te nuinga o te wai para hiko ka ahu mai i te wai horoi o ngā wāhanga whakakikorua me te iti o te wai para tukatuka. He rerekē te momo, te ihirangi me te āhua o ngā konganuku taumaha i roto i te wai para i runga i ngā momo whakaputanga rerekē, ko te nuinga kei roto ko ngā katote konganuku taumaha pēnei i te parahi, te chromium, te konutea, te cadmium, me te nikara. E ai ki ngā tatauranga kāore i oti, ko te tukunga wai para mai i te umanga whakakikorua anake i ia tau neke atu i te 400 miriona tana.
E mōhiotia ana te maimoatanga matū o te wai para hiko te tikanga tino whai hua me te tino taipitopito. Heoi, i runga i ngā hua o ngā tau maha, he raruraru kei te tikanga matū pēnei i te mahi kore pumau, te whai huatanga ōhanga me te pānga kino ki te taiao. He tino pai te otinga o te kaihoko maimoatanga wai whakarewa taumaha polymer. Ko te raruraru i runga ake nei.
4. Aromatawai whānui o te kaupapa
1. He kaha tōna kaha ki te whakaiti i te CrV, he whānui te awhe pH o te whakaiti i te Cr (2~6), ā, he paku waikawa te nuinga o ēnei.
Ka taea e te wai para te whakakore i te hiahia ki te tāpiri waikawa.
2. He tino kawakore, ā, ka taea te whakanui ake i te uara pH i te wā kotahi e tāpirihia ana. Ina tae te pH ki te 7.0, ka taea e te Cr (VI), Cr3+, Cu2+, Ni2+, Zn2+, Fe2+, me ētahi atu te eke ki te paerewa, arā, ka taea te whakapūpū i ngā konganuku taumaha me te whakaiti i te utu o te VI. Ka tutuki katoa te wai kua rongoatia i te paerewa tukunga tuatahi o te motu.
3. Utu iti. Ki te whakatauritea ki te konutai whanariki tuku iho, ka heke te utu tukatuka mā te neke atu i te RMB 0.1 ia tana.
4. He tere te tukatuka, ā, he tino whai hua te kaupapa tiaki taiao. He ngāwari te whakatau i te ua, e rua te tere atu i te tikanga raima. I te wā kotahi, ka tau te ua o F-, P043 ki roto i te wai para.
5. He iti te nui o te paru, he haurua noa iho o te tikanga matū tuku iho
6. Kāore he parahanga tuarua o ngā konganuku taumaha i muri i te maimoatanga, ā, he ngāwari te whakahoromata i te warowaihā parahi taketake tuku iho;
7. Me te kore e ārai i te kakahu tātari, ka taea te tukatuka tonu
