Wastewater kurapwa nzira: vazhinji, nani

The yakakwirira padanho yebudiriro, ndipo inobereka dongo. Nhasi, kupfuura zvaaida nguva yedu ndeinotevera: "Chii kuita kwavo tsvina sei kuchenesa Chii Mabatirwo tsvina uye dongo effluent ??"

Wokunatswa mvura inoyerera ichidzika zvaimutambisira, - a muitiro ane chinangwa ndiko kuparadzwa kana kuparadzwa zvinokuvadza uye netsvina mumvura iyi. Dzimwe nyanzvi dzinofunga kuti izvi zvichiitika yunifomu, asi ine mumatanho anoverengeka. Other wokunatswa danho rimwe nerimwe riri voga sezvo yakazvimirira nzira. Chero zvazvingava, rectification wastewater akashandisa nzira dzakasiyana-siyana acheneswe kubva wastewater. Ivo kunogadzirisika achibatsirwa:

• reagents, makemikari;
• sedimentation uye filtration;
• electrolysis;
• oxidation nezvimwe physico-mushonga transformations;
• Mabhakitiriya, utachiona, mamwe majemusi;
• nzira dzose kamwechete (mumatanho).

Selection imwe nzira zvinoenderana mukuru chinangwa

Mechanical nzira wastewater kurapwa

Basic nzira - filtration uye sedimentation. Kudeuka tsvina yabviswa ne gratings vane Pazvibato madiki nesefa.

Zvadaro, yakasvinwa mvura ichipfuura jecha misungo, inokosha Kamudzira uye septic matangi.

Utachiona vanobviswa pachiso achishandisa mafuta, mafuta kana benzinolovushek. Vakazopinda nokushandiswa filters rinobvumira mvura yakachena 75-95% nouipi, zvimwe zviri recyclable.

Chemical nzira wastewater

Saka akadana kuchenesa nzira, sezvamakaropafadzwa tsvina mvura hwakatangwa reactants decomposing tsvina. Kubva 25% soluble uye nzira kuti vakadaro anobvisa kusvika 75% insoluble tsvina.

Physicochemical nzira wastewater

Kana yokunatswa ichi vari anowanzodanwa kushandiswa:

1. Coagulation - "chokuedza" kuti inoramba yakanaka huru idzodzo.
2. Oxidation - maitiro umo kusvibiswa 'vakapisa "nokuda kuitwa reagents.
3. Sorption - Absorção de Água reagents utachiona kubva wastewater.
4. Extraction - dzokubudisa pakati yakaoma mvura zvinhu.

Kushandiswa adsorption, coagulation, dzokubudisa nezvimwe unyanzvi rubatsiro kubvisa particulate yakanaka, inorganic tsvina, kana kuparadza Organic utachiona vari havaratidzi oxidized.

Biological wastewater kurapwa nzira

Musimboti nzira iyi kuti kushandiswa chaivo pezvakaitwa kuti kuguma kuzvidzora pakuchenesa mvura. Nokuti rectification tsvina mvura inowanzoshandiswa:

1. Biofilters - mano kuburikidza iyo yakasvinwa mvura. Kubva kwakajairika biofilters vari kuzivikanwa ndechokuti pamusoro pemvura cultured anaerobic tusingaoneki kuti oxidize utachiona.
2. Aeration - mvura yokunatsa vanokwanisa, zvakavakwa kuti Akazadzisa kongiri. Pano tusingaoneki amoebae uye ciliates munguva hwavo zvibereko yl chingagumbusa okuchenesa kunoitika. Mushrooming mumadhaka amoebae, rotifers nezvimwe zvisikwa zvinokonzera chichiitwa rejuvenation ari madhaka substrate. Biological pezvakaitwa vari kukura nokukurumidza nokuti zvinenge akapa kuramba tichiwana dzichifura - tsvina mvura.
3. Biological madziva - hurongwa murume akaita adzivirire mvura, kushanda papfungwa rwokuzvarwa kuzvidzora okuchenesa. Kwacho unogadzirira zvipenyu zviduku zvose kurarama mudhamu.

Electrolytic nzira rokuchenesa wastewater

Mari-inobudirira zvikuru ivo apo wastewater kwakasvibiswa yakawanda simbi kuchena vari pendi, mhangura indasitiri, etc. The rokuchenesa kwacho rinoitwa munyika chaiyo mumagaba.
