Mvura ndiyo hwaro hwezvinhu zvekupona kwePasi biology. Zviwanikwa zvemvura ndiwo mamiriro ekutanga ekuchengetedza kusimukira kwakasimba kwemhoteredzo yepasi. Naizvozvo, kuchengetedza zviwanikwa zvemvura ibasa guru uye rinoera kwazvo revanhu. Mazuva ano, matsime emvura akawanda ari kusvibiswa, uye kune mvura shoma shoma. Makambani mazhinji atanga kushandisa bvunzo dzemvura. Nhasi, ndichakuzivisa iwe zvakadzama.
1. Kupindirana kweutano hwemuviri nepfungwa hwevanhu: Mushure mekusvibiswa kwemvura, maererano nemvura yekunwa kana network yezvokudya, zvinosvibisa zvinopinda mumuviri, zvichiita kuti vanhu vaome kana kuti vane chepfu. Arsenic, chromium, ammonium, benzene (A) , zvichingodaro, zvinogona kukonzera cancer syndrome. Mvura yakasvibiswa nekusvibiswa kwezvakatipoteredza kwehutachiona hwehutachiona kana mamwe mabhakitiriya epathogenic anogona kukonzera zvirwere zvakasiyana-siyana zvinotapukira uye zvirwere zveparasitic.
2. Kukuvadzwa kwekugadzirwa kwemaindasitiri: Mushure mekunge nharaunda yemuviri wemvura yasvibiswa, mari inodiwa inofanirwa kuiswa mukugadzirwa kwetsvina yeindasitiri kugadzirisa mutengo, zvichikonzera umbozha uye kutambisa zviwanikwa, simba uye simba. Kugadzira kunomira.
3. Kukuvadzwa kwezvokudya zvakawanda: Mumamiriro ezvinhu akajairika, oxygen inonyungudika mumvura. Okisijeni okisijeni haisi iyo chete chiyero chekupona kwemvura biological microorganisms, asiwo kunyoresa okisijeni kutora chikamu mune dzakasiyana siyana oxidation-zvinoita mumvura uye kukurudzira shanduko yezvinosvibisa. Ndiyo kiyi yemhando yakachena yemvura yakasikwa.
Nekufambira mberi kwekusimudzira magariro, dambudziko rekusvibiswa kwezvakatipoteredza riri kuramba richinyanya kuoneka. Uye kubva pakaitwa ISO14000 nhevedzano yezvakatemwa zvechigadzirwa, nyika dzepasirese dzakabva dzakwenya maitiro ekuongorora nekuona, uye kuziva kuchengetedza zviwanikwa zvemvura kwawedzera kuvandudzwa.
1. Kuona mvura ine tsvina:COD, BOD, ammonia, phosphorus yakazara, nitrogen yakazara, fluoride, sulfides, heavy ions, anion surface active agents, nezvimwewo.
Industrial Production Wastewater (Chirungu: Industral Wastewater) ine yekugadzira mvura yetsvina uye kugadzira kugadzira tsvina yemvura, iyo inoreva mvura yetsvina uye tsvina inokonzerwa nemaitiro ese ekugadzirwa kwemaindasitiri. Mariri Zvinosvibisa zvakakonzerwa mukugadzira. Mvura yakabudiswa mukugadzira.
Zvinoenderana nehunhu hwezvinhu zvakakosha zvinosvibisa muindasitiri yekugadzira tsvina yemvura, yakakamurwa kuita: inorganic tsvina inodzorwa neinorganic tsvina, organic kemikari tsvina yemvura inodzorwa nezvinosvibisa organic, tsvina yakasanganiswa, heavy metal ine organic compounds uye inorganic compounds, uye inorganic compounds Waste. mvura inodarika mvura yakajairwa, mvura yetsvina ine radioactive elements, uye inotonhorera inotenderera mvura yakasvibiswa nenharaunda yekupisa. Semuenzaniso, mvura yetsvina ye electroplating process mvura yetsvina uye mineral production process is inorganic wastewater, uye mvura yetsvina yechikafu kana mafuta process process is organic chemical wastewater.
Zvinoenderana nezvigadzirwa zvemabhizinesi ekugadzira zvinhu uye kugadzirwa uye kugadzirisa zvinangwa, zvinogona kukamurwa kuita mapepa ekugadzira maindasitiri mvura yetsvina, machira etsvina, toni yetsvina, fetireza tsvina yemvura, metallurgical maindasitiri tsvina, uye pamusoro-mafuta ekunatsa tsvina.
Zvinhu zvakakosha zvezvinosvibisa mumvura yetsvina zvinogona kukamurwa kuita pH tsvina, alkaline wastewater, phenol-ine tsvina ine tsvina, chromium-ine tsvina yemvura, organic phosphorus tsvina, uye radioactive zvinhu tsvina yemvura.
Chete mvura yetsvina mukati meiyo yakajairwa chiyero mushure mekugadziriswa kwemvura yetsvina uye kuona inogona kuburitswa kunzvimbo yakatarwa. Zvinorambidzwa kuburitsa zvinodarika mwero uye kurambidza kuburitsa zvisiri pamutemo.
Chechipiri, kuonekwa kwezvipfeko, zvokudya, pekugara uye kutakura mvura yakasvibiswa: pH kukosha, CODCR, NH3-N, TP, SS, mafuta asina kuchena, mhuka nemafuta emiti, nezvimwewo.
Chechitatu, kuonekwa kwemvura yepamusoro: pH kukosha, NH3-N, TP, SS, biochemical oxygen kudiwa, nezvimwe.
Mamiriro echisikigo emvura yakadzika yepasi pemvura uye kuchengetedzwa kwechinangwa chakazara chinoiswa sezvikamu zvishanu zvichienderana nehurefu hwekushanda. Mhando shanu dzemvura dzenzvimbo dzepamusoro pemvura dzakakamurwa kuita zvikamu zvishanu zvepurojekiti nyowani yemhando yepamusoro pemvura yepamusoro. Mataipi ega ega shandisa imwe yemhando yechiratidzo kukosha. Yakakwirira chiratidzo kukosha nemhando dzepamusoro dzinoshanda dzakarohwa pane chiratidzo chemhando ine yakaderera inoshanda marudzi emvura. Mumvura imwe cheteyo, kune akawanda marudzi emabasa ekushandisa, uye kukosha kwechiratidzo kunoenderana neakanyanya kushanda marudzi anoitwa. Kuchengetedza basa remvura uye maitiro ekushanda kwemaitiro zvinoreva zvakafanana.
Chechina, kuonekwa kwemvura yepamusoro: mvura yakachena uye magetsi ekutungamira, heavy metal inodarika iyo yakajairwa yakanaka ion, nezvimwe.
Chirongwa chitsva:
Aniline, indoor formaldehyde, saturation, yakamiswa yakasimba, pH kukosha,mazuva mashanu biochemical oxygen inoda (BOD5), permanganate index, CODcr, phosphorus yakazara, polyphosphate, chloride, arsenic yese, hexavalent chromium, yakazara chromium, hydrogen cyanide, volatile phenol, mhuka nemiriwo mafuta, cationic surfactant, iron, manganese, nickel, volatile phenol, tembiricha, yakanyungudika yakazara nitrogen, mhangura, cadmium, zingi, lead, nezvimwe.
Kukosha kwekuonekwa kwemhando yemvura:
Kuchengeteka kwemvura yakachengeteka: Kutarisisa kwemhando yemvura kunogona kuwana panguva yakakodzera zvinosvibisa uye zvinokuvadza zvinoonekwa mumatsime emvura nemapombi network, kudzivirira kunaka kwemvura kubva pakusvibiswa uye kuve nechokwadi chehupenyu uye hutano hwevagari.
Kuongorora kusvibiswa kwezvakatipoteredza: Zviteshi zvekutarisa zvemhando yemvura munzvimbo dzakasiyana-siyana zvinoedzwa pamhando dzakasiyana dzezvinhu munzvimbo dzakasiyana-siyana dzemvura dzakaita senzizi nemadziva, uye dzinoshuma kusvibiswa kwemvura kunokonzerwa nemvura, maindasitiri, uye hupenyu huri mumvura. kurima kwevhu, indasitiri, uye hupenyu nenguva.
Kufembera kwechitubu chemvura shanduko: Kuburikidza nekutarisa kwemhando yemvura, unogona kunzwisisa huripo hutsanana mhando, nharaunda yezvakatipoteredza uye kusvibiswa kwezvinhu kwemitumbi yemvura, uye wozofanotaura mafambiro ezvitubu zvemvura uye kutungamira kusimudzira nekushandiswa kwezviwanikwa zvemvura.
Kuongorora uye kutonga kwemaitiro: Kugara uchitarisa kunaka kwemvura kunogona kunzwisisa panguva yakakodzera mhedzisiro yehutongi kusvibiswa nemhedzisiro yayo, uye kupa vashandi vezvekutarisira kwezvakatipoteredza kuti vagadzirise uye vagadzirise chirongwa chekutonga uye matanho nenzira yakakodzera nguva yekuvandudza mhedzisiro yekutonga.
Muchidimbu, kutariswa kwemhando yemvura, sehwaro hwekusimudzira nekushandiswa kwezviwanikwa zvemvura, kunopa vimbiso yakakosha pakuchengetedzwa kwezvakatipoteredza, kugadzirisa zviwanikwa uye kushandiswa, uye hupenyu hwevagari vemo.
