Mushure meKurume, dzimwe nzvimbo dzinopinda mumamiriro ekunze emvura kwenguva refu, uye tembiricha inochinja zvakanyanya.

Munguva yemvura, mvura yakawanda inoita kuti magamba neshiri dzive mumamiriro ekushushikana, uye inoderedza zvakanyanya kushinga kwezvirwere.

Kuwanda kwezvirwere zvakaita sekubuda ropa mudumbu, kubuda ropa mudumbu, kubuda ropa mudumbu rine mavanga machena nezvimwewo zvichavandudzika zviri pachena.

Ndezvipi zvinetso zvatinofanira kutarisa munguva yemvura?

1. Kuchinja kwekushisa kwemvura.

Kazhinji, tembiricha yemvura yemvura yakaderera pane yemvura yedziva remashrimp, uye musiyano wetembiricha

pakati pavo panonyanya kuipa muzhizha.

2.Kushaya okisijeni mumvura.

Mvura inonaya inotungamira mukupatsanurwa kwemvura ine munyu neyakachena, zvichikanganisa mvura yepasi nemvura yepamusoro.

Kuchinjana kweokisijeni kwemvura, kushaya okisijeni kwemvura iri pasi.

3. Mvura inova yakachena

Kufa kwehuwandu hwakawanda hwealgae hakungosvibisi madziva eshrimp zvakananga chete, asiwo kunoita kuti akure moss,

izvo zvinoita kuti shrimp ive nengozi zvikuru.

4. Kuora kwehunhu hwemvura

Kuwedzera kwekudiwa kweokisijeni yemakemikari (COD), kuwedzera kwezvinhu zvinokuvadza zvakaita seammonia nitrogen uye

nitrite mumvura, uye kupinza mvura inonaya, zvichikonzera kudzikira kwepH, uye kuora kwemhando yemvura munguva pfupi.
