Enda munzvimbo yekuchenesa tsvina uye uongorore chakavanzika chetsvina haisisiri "tsvina"!

Unoda kuziva here?

Mazuva ese patinosuka chimbuzi, kugeza, kugeza ndiro...

Ko tsvina inopinda musuweji inoendepi?

Nhasi, Dazu urban sewage treatment plant

yakazarukira veruzhinji pamusoro pegore

Ngationgororei chakavanzika chetsvina haichave "tsvina"!

Maitiro 1: Coarse screen kamuri uye yemvura inopinza pombi imba

Bvisa marara makuru uye zvinhu zvinoyangarara mutsvina inopinda mufekitari

Simudza tsvina yetsvina kubva pakadzika pasi pevhu

kune chimiro chekurapa kwepamusoro

Maitiro 2: Yakanaka skrini yekamuri uye dutu rejecha rekugadzirisa tangi

Inobvisa zvidimbu zvakakura zvejecha (zvakadzidziswa), bvudzi uye pfupi fiber fluff mutsvina

Inobvisa zvidimbu zvejecha nehukuru hwe ≥0.2mm mutsvina

Inoparadzanisa inorganic jecha zvidimbu kubva organic matter

Maitiro echitatu: Yekutanga sedimentation tankBvisa scum

Bvisa mamwe maSS neCOD

Uyewo anogona homogenize mvura kunaka

Maitiro 4: Yakavandudzwa oxidation ditch

Shandisa akasiyana mabasa eanaerobic, anoxic uye aerobic zones

Kunyanya kuderedza BOD5, COD uye nitrification uye denitrification

Ita biological nitrogen uye phosphorus kubvisa.

Maitiro 5: Sekondari sedimentation tank

Maitiro 6: Kudzika kwakadzika

(yakanaka chidzitiro kamuri, sefa jira sefa tangi)

Bvisa zvimedu zviduku mumvura yetsvina

Sefa tsvina kubva kune yechipiri sedimentation tank

Kuwedzera kuderedza

SS, TN, TP uye zvimwe zviratidzo zvinosvibisa mumvura

Maitiro 7: Bata disinfection tank

 

Uraya mabhakitiriya uye mavhairasi anogona kunge ari mufekitori tsvina yemvura

Nzira 8: Kubuda kwemvura

Sewage inoenda kunzvimbo yekuchenesa tsvina ye "rwendo"

Chikamu chayo chinoshanduka kuva gasi (carbon dioxide, etc.) uye inobudiswa mumhepo

Chikamu chayo chinogadzika uye chinoshanduka kuita matope

Inobatwa nekambani inokwanisa

Δ Yechitatu-bato yepamhepo yekutarisa yemhando yemvura

Mvura yakasara

Hunhu hwemvura yakasviba hunofanira kusangana
