Zida Zoyeretsera Madzi Pansi Pansi Pansi

Mafotokozedwe Akatundu

Njira zoyeretsera madzi a mvula ndizofunikira kwambiri pamachitidwe osonkhanitsa madzi amvula.Nthawi zambiri, madzi amvula omwe amasonkhanitsidwa ndi madzi amvula amagwiritsidwa ntchito kuyeretsa, kuthirira, ndi kutsuka zimbudzi.Choncho, njira zoyeretsera madzi amvula zimasiyanasiyana malinga ndi kusonkhanitsa ndi kugwiritsa ntchito madzi amvula m'madera osiyanasiyana.

Choyamba, m'pofunika kusanthula khalidwe la madzi a mvula omwe amasonkhanitsidwa ndi dongosolo.Pa nthawi ya mvula, mpweya wosungunuka, zosungunuka kapena zoyimitsidwa, zitsulo zolemera, ndi tizilombo toyambitsa matenda kuchokera mumlengalenga zimatha kulowa m'madzi amvula.Zowononga zomwe zimasefukira pamtunda makamaka zimachokera ku mphamvu ya madzi amvula akutsuka pamwamba.Chifukwa chake, matope a pamtunda ndiye gwero lalikulu la zoipitsa m'madzi osefukira.Kapangidwe ka sedimentation pamtunda kumatsimikizira mtundu wa kuwonongeka kwa madzi otuluka pamwamba.Choncho, madzi amvula amasiyanasiyana chifukwa cha malo ndi nthawi zosiyanasiyana.Kupyolera mu kufufuza kwa khalidwe la madzi a mvula, amakhulupirira kuti zowononga madzi amvula achilengedwe makamaka zimaphatikizapo SS, COD, sulfides, nitrogen oxides, ndi zina zotero, koma kuchuluka kwake kumakhala kochepa.

Pochiza madzi amvula, kusefera kwa kaboni ndi kusefera kwa mchenga kumagwira ntchito yofunika.Kusefera kwa kaboni kumagwiritsidwa ntchito kwambiri kuchotsa zinthu zachilengedwe, fungo ndi mitundu, komanso kukonza madzi.Amachotsa organic zinthu ndi klorini kudzera adsorption ndi mankhwala zimachitikira, potero kusintha kukoma ndi fungo la madzi.Kusefedwa kwa mchenga kumagwiritsidwa ntchito kuchotsa zolimba zoyimitsidwa, matope ndi zinthu zina zolimba kuti madzi azikhala omveka bwino.Njira ziwiri zoseferazi zimagwiritsidwa ntchito kwambiri m'makina osonkhanitsira madzi a mvula kuti madzi amvula asonkhanitsidwe akwaniritse miyezo yaubwino wamadzi ndipo atha kugwiritsidwa ntchito pa ulimi wothirira, kuyeretsa ndi zina zomwe sizimamwa.Angagwiritsidwenso ntchito m'makina opangira madzi amvula m'nyumba za mafakitale ndi zogona kuti ayeretse madzi amvula ndikuwapangitsa kuti agwiritsidwenso ntchito.

1.Njira yopangira madzi amvula imakhala ndi makhalidwe othamanga mofulumira, kuthamanga kwapamwamba, zotsatira zabwino, kugwira ntchito mokhazikika, ndi kuchepa kochepa;
2. Kusonkhanitsa konse kwa madzi amvula kumakhala ndi phazi laling'ono, maonekedwe okongola, ntchito yosavuta, ndi kusamalira bwino.
3. Kuchita bwino komanso kupulumutsa mphamvu, kugwiritsa ntchito mphamvu zochepa, kugwiritsa ntchito mankhwala ochepa, komanso kupanga zinyalala, kuchepetsa kwambiri ndalama zoyendetsera eni nyumba poyeretsa madzi amvula;
4. Mapangidwe apadera, luso lamakono, digiri yapamwamba ya automation, osafunikira kasamalidwe odzipereka;
5. Njira yoyeretsera madzi amvula imakhala ndi dongosolo losavuta, imapulumutsa ndalama zopangira madzi amvula, ndipo imakhala ndi ndalama zochepa zogwirira ntchito;
