Tinoziva kuti chivharo chependi chinoiswa mumvura inotenderera muworkshop yekupenda, uye chinhu chinogona kubvisa pendi inopfurwa zvakanyanya panguva yekupfapfaidza, uye chivharo chinopfurwa zvakanyanya chinobviswa uye chinoparadzirwa, zvichiita chinhu chakasimba chiri nyore kuparadzaniswa nemvura, zvichiita kuti pave nekuparadzaniswa kwemvura yakasimba, nokudaro zvichichenesa mvura inotenderera uye zvichienderera mberi nebasa remvura inotenderera ichinwisa pfurwa yependi inopfurwa. Saka tingatonga sei mhedzisiro yekushandiswa kwepurwa rependi pane mwero here?

Maitiro ekutonga mhedzisiro ye coagulant yependi:
1. Tarisa mamiriro ekuyangarara kwependi: Mushure mekushandisa pendi yemist coagulant, isa sampuro yekuyedza woienzanisa kuti uone mamiriro ekuyangarara uye mamiriro ekuyangarara ependi. Kana pendi yemist slag iri pedyo uye mamiriro ekuyangarara ari nani, mhedzisiro yacho inowedzera.
2, cherechedza kujeka kwehunhu hwemvura: enzanisa tsvina yependi mushure mekuyedza, hunhu hwemvura hwakajeka uye huwandu hwekuwedzera hushoma.
3, dhigirii rekurapa slag yependi:

① Pendi haina kunamira, seyakaiswa paganda re tofu;
(2) Chikamu chidiki chependi inonamira, pendi inonamira yakapfava, uye chidimbu chidiki chependi chinonamirwa chakatenderedza beaker;
(3) Pendi inonamirawo uye haisi nyore kuibvisa, kazhinji muchiitiko ichi kungave kuri kuwedzera pendi ine fog coagulant kusina kukwana kana kuti sarudzo yacho haina kunaka.

Hunhu hwechigadzirwa chependi mhute inoboora
1, pendi mhute coagulant chigadzirwa chemvura, chiri nyore kushandisa uye kushanda.
2. Chinhu chinobatanidza mhute yependi chine basa rekuora, kubvisa viscosity uye kunyungudutsa, izvo zviri nyore kuchengetedza nekubvisa.
3, mushure mekushandisa, mvura inogona kuwedzera kutenderera kwemvura.
