Kuchenesa polymer inorema simbi yemvura kurapwa

Kugona kuongororwa kwekushandisa kwekushandisa muindasitiri marara kurapwa

1. Basic Sumo

Kusvibiswa kwesimbi inorema kunoreva kusvibiswa kwezvakatipoteredza kunokonzerwa nesimbi inorema kana makomendi avo. Inonyanya kukonzerwa nezvinhu zvevanhu zvakadai sekunyepedzera, marara gasi, sewage kudiridza uye kushandiswa kwezvinhu zvinorema zvesimbi. Semuenzaniso, chirwere chemamiriro ekunze chine mvura uye chirwere chinorwadza muJapan chinokonzerwa nekusvibiswa kwemvumo uye kusvibiswa kweCadmium zvichiteerana. Dhigirii rekukuvara rinoenderana nekushomeka uye nemakemikari emitezo inorema mumagariro, chikafu nezvisikwa. Kusvibiswa kwesimbi inorema kunonyanya kuratidzwa mukusvibiswa kwemvura, uye chikamu chayo chiri mumhepo nemarara uye marara akasimba.

Simbi dzinorema dzinoreva simbi ine simba (density) yakakura kupfuura 4 kana 5, zinn, titcury, mangange, many, sirivheri, et. Trace zvinhu zvinodiwa zviitiko zvehupenyu, mazhinji emasimbi anorema senge mercury, anotungamira, etc. hazvidikanwe kuti zvinhu zvevamwe zvinyoronyoro zvine chepfu kune muviri wemunhu.

Simbi dzinorema dzinowanzoratidzwa mune zvakasikwa mune zvakasikwa pfungwa. Nekudaro, nekuda kwekuwedzera kwekurovedzwa, kuongorora, kugadzirisa uye kutengeserana simbi inorema nevanhu, mitezo mizhinji inorema senge, Mercury, Cadmium, Cadmium ,,. Kukonzera kwakakomba kusvibiswa kwezvakatipoteredza. Simbi dzinorema mumakemikari akasiyana emakemikari kana mafomu emakemikari achapfuurira, kuunganidza uye kutama mushure mekupinda nharaunda kana ecosystem, zvichikonzera kukuvara. Semuenzaniso, masimbi anorema anodzingwa nemarara anogona kuunganidza muAlgae uye pasi pematoro uye fungidziro idiki, uye ichinetseka pamusoro pehove, zvichikonzera kuchenesa ketani, nekudaro kukonzera kusvibiswa. Semuenzaniso, kurwara kwemvura muJapan kunokonzerwa nemvura mumvura yakabviswa kubva kune iyo caustic soda yekugadzira indasitiri, iyo inoshandurwa kuita organic mercury kuburikidza nezviito zvekubatsira. Mumwe muenzaniso unorwadziwa, izvo zvinokonzerwa neCadmium yakabviswa kubva kuZinc Inonamatira yeChamsita uye iyo Cadmium Electroplating Indasitiri. . Tungamira Kubviswa Kubva Kuneta Kwemotokari kunopinda Mamiriro ekunze

Macromolecular anorema simbi emvura kurapwa, brown-tsvuku-tsvuku polymer, inogona kukurumidza kuwirirana nemwenje Nzira yekurapa iri nyore uye yakapusa, mutengo wakaderera, mhedzisiro yacho inoshamisa, huwandu hwesimbe idiki, hwakagadzikana, husina chepfu, uye hapana kusvibiswa kwechisere. Inogona kushandiswa zvakanyanya mukurapa kwemarara muindasitirwi yemagetsi, miganhu uye kunhuwa, simbi yekugadzirisa maindasitiri, chirimwa chirimwa chakashata uye mamwe maindasitiri. Inoshanda pH range: 2-7.

2. Chigadzirwa Chigadzirwa Chinzvimbo

Semukati inoshanda kwazvo simbi ion inokwana, ine huwandu hwakawanda hwekushandisa. Inogona kushandiswa kweanenge nguva yese yematare ine inorema simbi ions.

3. Shandisa nzira uye maitiro akajairika kuyerera

1. Mashandisiro Aungaita

1. Wedzera uye kumutsa

Wedzera polymer inorema simbi kurapa mumiriri zvakananga kune iyo inorema simbi ion-ine marara marara, maitiro ekunzwisisa, iyo nzira yakanakisa ndeyekutsvaira kose-nguva-nguva;

②NE isingazivikanwe simbi yesimbi mumarara, mafungu emarabhoritari anofanirwa kushandiswa kuona huwandu hwesimbi inorema yakawedzera.

③NE kurapwa kwesango rine marara ane marara ioni neakasiyana midziyo, huwandu hwezvinhu zvisina kugadzirwa zvinowedzerwa zvinogona kudzorwa otomatiki neOP

2. Chaizvoizvo michina uye maitiro ehunyanzvi

1. Kufunga nezvemvura 2. Kuti uwane pH = 2-7, Wedzera acid 9, Reservoir 10, Filta 121, Final PH Kudzora kweDhivhosi Pool 12, Discharge Mvura

4. Kuongororwa kwezvehupfumi zvakanaka

Kutora magetsi emagetsi matsime seyakajairwa simbi yesimbi yemarara semuenzaniso, mune iyi indasitiri yega, makambani ekushandisa anowana makomborero makuru uye ehupfumi. Electroplating Wastwater inonyanya kubva kumvura yekukanda yekuisa zvikamu zvekuisa zvikamu uye huwandu hushoma hwekugadzirisa hunotambisa mvura. Type, zvemukati uye chimiro chesimbi inorema mumarara akasiyana kwazvo nemhando dzakasiyana-siyana dzesimbi dzesimbi, dzinonyanya kuve nesimbi simbi sesvhinzi, Chromium, zinc, cadmium, uye nickel. . Sekureva kwehuwandu husina kukwana, iyo yegore negore yemvura kubva kune yakasviba indasitiri yeElectrolating yega inodarika mamirioni mazana mana emamiriyoni emamiriyoni ematani.

Kumakemikari kurapwa kweElectroplating Trustrater inozivikanwa seyakanyanya kushanda uye zvakakwana nzira. Nekudaro, achitonga kubva kumhedzisiro yemakore mazhinji, nzira yemakemikari ine matambudziko akadai asingagadziki kushanda, kushanda kwehupfumi uye nemamiriro ekunze emamiriro ekunze. Iyo polymer inorema simbi yemvura yekurapa mumiririri anogadziriswa zvakanaka. Dambudziko iri pamusoro.

4. Kuongororwa kwakazara kweiyo purojekiti

1. Iyo ine yakasimba yekuderedza kugona, iyo pH yakakura yekudzora cr "iri yakafara (2 ~ 6), uye vazhinji vavo vari acidic

Iyo yakasanganiswa marara inogona kubvisa iyo inofanirwa kuwedzera acid.

2. Iyo yakasimba alkaline, uye iyo pH kukosha kunogona kuwedzera panguva imwe chete iyo yakawedzerwa. Kana pH rasvika :0, CR (vi), Cr3 +, Ni2 +, fe2 +, its, simbi dzinorema dzinogona kuve dzakarongedzwa uchideredza mutengo weVI. Mvura yakabatwa yakazara inosangana neyenyika yekutanga-kirasi discharge standard

3. Mutengo wakaderera. Kuenzaniswa neiyo tsika yesodium sulfide, mutengo wekugadzirisa unoderedzwa neanopfuura rmb 0.1 pane toni.

4. Kukumhanya kwekugadzirisa kuri kukurumidza, uye chirongwa chekudzivirira kwezvakatipoteredza zvinoshanda zvakanyanya. Iyo yekunyora iri nyore kugadzirisa, iyo yakapetwa kaviri senge nzira ye lime. Panguva imwe chete yeF-, p043 mune marara

5. Kuwanda kweshumba idiki, hafu yenzira yechinyakare yemakemikari

6. Iko hakuna kusvibiswa kwechisere kwekurapwa mushure mekurapwa, uye tsika dzechinyakare dzemhangura copper zviri nyore kuHydrolyze;

7. Pasina kuvhara jira rekufa, rinogona kugadziriswa nguva dzose
