Nzwisisa nheyo yekuchenesa tsvina

Nekuvandudzwa kwehupfumi, mvura kusvibiswa kuri kuramba kuchiwedzera, nyika yakawedzera zvishoma nezvishoma kusimba kwekugadziriswa kwetsvina yemumaguta, kunyanya mumakore achangopfuura, chiyero yekudyara kwayo inoramba ichiwedzera, uye kumhanya kwekuvaka kwetsvina mishonga yekurapa yakawedzera zvakanyanya. Vanhu vazhinji vanoda kuziva, chii ndiyo nzira yekuchenesa pasuru yetsvina? Zvijekese mune imwe nyaya. Nzwisisa nheyo yekuchenesa tsvina

Kune nzira mbiri chete dzekuchenesa tsvina: imwe ndeyekuparadzanisa, uye imwe yacho kutendeuka.Nzwisisa musimboti wekuchenesa tsvina

Kuparadzanisa ndiko kuparadzanisa zvimwe zvinosvibisa mutsvina kubva mumvura muviri, iwo matanho chaiwo anosanganisira kunaya, kuyerera, centrifugation, kuyerera kwemhepo, kuvhuvhuta uye zvichingodaro, iyo yakakosha yemuviri uye makemikari nzira. Kazhinji, zvinosvibisa mutsvina senge organic zvinhu zvinogona kubviswa mushure mekuparadzaniswa kwekutanga uye kurapwa, uye zvinodiwa ndizvo kwete yakakwirira, saka inogona kubudiswa zvakananga. Izvi zvinonzi primary processing.

Zvimwe zvinosvibisa hazvigoni kuparadzaniswa zvinobudirira, zvakadai sokunyungudutswa organic matter, ammonia nitrogen, phosphates, izvo zvinoda kushandurwa kuita zvinhu zvisingakuvadzi, kana zvinhu zvinoparadzaniswa nyore nyore. Chinonyanya kukosha biochemical process mukurapwa kwetsvina ibasa rekushandura semuenzaniso, yakanyungudika organic matter inobviswa nekushandura organic matter kuita kabhoni diokisi (iyo kazhinji isingakuvadzi uye inoparadzaniswa nyore nyore kubva mumvura) uye biological sludge (inokuvadza, asi zvakare inonaya nyore uye yakaparadzaniswa). Izvi inonzi secondary processing. Kune nzira dzakawanda dzekushandura, dzakadai se dzakasiyana-siyana yepamusoro oxidation, acid-base neutralization uye zvichingodaro. Iyo cyanide tsvina inogadzirwa neTianjin kuputika mutsaona inogona chete kuputswa ne yakasimba oxidation yehydrogen peroxide kutyora C-N chisungo uye kugadzira zvisina ngozi.

Iyo nzira yekugadzira tsvina yemumba inowanzoita 1 grid 2 yekutanga kunaya 3 biochemical treatment 4 yechipiri kunaya 5 disinfection. Kubva muchikamu chepamusoro, 124 kupatsanurwa uye makumi matatu neshanu shanduko. Izvi rudzi rwakasiyana rwekuita, kunyangwe yakagadzikana uye iri nyore, asi inotora nzvimbo yakakura, mari yekuvaka yakakwirira, nguva yekugara kwenguva refu (inogona kunzwisiswa sehombe huwandu hwezvivakwa hunotora nzvimbo yakakura).

Iye zvino matekinoroji matsva ari kuwedzera kuda kusanganisa kupatsanurwa uye kushandurwa kuita seti yemasisitimu ekudzikisa mutengo nekuvandudza kushanda zvakanaka, senge membrane biological treatment process (MBR), inova biochemical process uye yekutanga uye yechipiri sedimentation kupinda mudziva, saka zviri pachena the tsoka dzakaderedzwa zvakanyanya. Kunyangwe iyo mutengo we membrane process ndeye ichiri yakakwira, nekufambira mberi kwehunyanzvi, mutengo uchave wakaderera uye yakaderera, uye ichange ichinyanya kufarirwa.
