27. Chii chakazara chimiro chemvura yakasimba?
Chiratidzo chinoratidza huwandu hwakasimba hwemukati memvura izere solids, iyo yakakamurwa kuita zvikamu zviviri: volatile yakazara solids uye isiri-inotenderera yakazara solids.Zvakaoma zvese zvinosanganisira zvakaturikwa zvimedu (SS) uye zvakanyungudutswa zvakaomeswa (DS), chimwe nechimwe chinogona zvakare kukamurwa kuita zvinhu zvinoputika uye zvisingaite.
Iyo yekuyera nzira yezvizere zvakaonda ndeyekuyera huwandu hwechinhu chakasimba chasara mushure mekunge mvura yetsvina yabuda pa103oC ~ 105oC.Nguva yekuomeswa uye saizi yezvimedu zvakasimba zvine hukama neyakaomeswa yakashandiswa, asi chero zvakadaro, kureba kwenguva yekuomeswa kunofanirwa kuve kwakavakirwa paKubva pakubuda kwemvura mumuenzaniso wemvura kusvika huwandu hwave huchienderana. nguva dzose mushure mekuoma.
Volatile total solids inomiririra huremu hwakasimba hwakadzikiswa nekupisa huremu hwese patembiricha yepamusoro ye600oC, saka inodaidzwawo kunzi kurasikirwa nehuremu nekupisa, uye inogona kumiririra zviri mukati meiyo organic zvinhu mumvura.Nguva yekubatidza yakangofananawo nenguva yekuomeswa pakuyera zvinhu zvakaonda.Inofanirwa kupiswa kusvika kabhoni yese yemumuenzaniso yabuda.Huremu hwezvinhu zvakasara mushure mekupisa ndiyo yakagadzika yakasimba, inozivikanwawo semadota, iyo inogona kumiririra zviri mukati meiyo inorganic matter mumvura.
28.Ndezvipi zvakanyungudutswa zvikukutu?
Zvimedu zvakanyungudutswa zvinonziwo zvinosefa.Iyo filtrate mushure mekusefa iyo yakamiswa yakaoma inoputika uye yakaomeswa patembiricha ye103oC ~ 105oC, uye huwandu hwezvinhu zvakasara hunoyerwa, inova yakanyungudika yakaoma.Yakanyungudutswa yakaoma inosanganisira inorganic munyu uye organic zvinhu zvakanyungudutswa mumvura.Inogona kuverengerwa kuverengerwa nekubvisa huwandu hwezvakarembera zvakaomeswa kubva kune yakazara yakaoma.Iyo yakajairika unit ndeye mg/L.
Kana tsvina ikashandiswa zvakare mushure mekurapwa kwepamusoro, zvinyoro zvaro zvakanyungudutswa zvinofanirwa kudzorwa mukati mehumwe huwandu.Zvikasadaro, pachave nemimwe mhedzisiro yakaipa ingave ichishandiswa kusvibira, kugezesa chimbuzi, kugeza mota uye mamwe mvura akasiyana kana semvura inotenderera mumaindasitiri.Ministry of Construction standard "Mvura Yemhando Yemvura Yemumba Yakasiyana-siyana" CJ/T48-1999 inotara kuti zvakanyungudutswa zvemvura yakashandiswa zvakare kushandiswa kusvibira nekutsvaira muchimbuzi hazvigone kudarika 1200 mg/L, uye zvakanyungudutswa zvemvura yakashandiswa zvakare kumotokari. kuwacha uye kuchenesa Haikwanise kudarika 1000 mg/L.
29. Chii chinonzi munyu uye munyu wemvura?
Munyu wemunyu uri mumvura unonziwo salinity, iyo inomiririra huwandu hwemunyu uri mumvura.Iyo yakajairika unit ndeye mg/L.Sezvo munyu uri mumvura wese uripo muchimiro cheiyoni, munyu unowanikwa muhuwandu hwehuwandu hwemaanioni akasiyana uye cations mumvura.
Zvinogona kuonekwa kubva mutsanangudzo yekuti zvakanyungudutswa zviri mumvura zvakakura kudarika munyu, nekuti zvakanyungudutswa zvinewo zvimwe zvinhu.Kana iyo organic matter iri mumvura yakadzikira zvakanyanya, yakanyungudika dzimwe nguva inogona kushandiswa kuenzanisa munyu uri mumvura.
30. Chii chinonzi conductivity yemvura?
Conductivity ndiyo inopindirana yekupikisa kwemushonga wemvura, uye chikwata chayo μs/cm.Yakasiyana-siyana soluble salts mumvura iripo mune ionic state, uye aya maion ane kugona kuitisa magetsi.Iyo yakawanda munyu yakanyungudutswa mumvura, inowedzera iyo ion yemukati, uye yakakura conductivity yemvura.Nokudaro, zvichienderana nekugadzirisa, inogona kumiririra zvisina kunanga huwandu hwemunyu mumvura kana iyo yakanyungudutswa yakasimba yemvura.
Iko conductivity yemvura yakachena yakasvibiswa ndeye 0.5 kusvika 2 μs / cm, conductivity yemvura yakanyanyisa iri pasi pe 0.1 μs / cm, uye conductivity yemvura yakadzika inobudiswa kubva kune zviteshi zvemvura zvakapfava zvinogona kusvika kuzviuru zve μs / cm.
