Ndeipi basa rePolyaluminium Chloride mune aquaculture?

Indasitiri yemvura ine zvakawanda zvinodikanwa zvemhando yemvura, saka zvakasiyana-siyana organic zvinhu uye zvinosvibisa mumvura yeaquaculture zvinoda kurapwa nenguva. Nzira yakajairika yekurapa parizvino ndeyekuchenesa mvura yemhando kuburikidzaFlocculants.

Mumvura yetsvina inogadzirwa neaquaculture indasitiri, kune mashoma marudzi ezvinosvibisa, shanduko diki mune zvemukati, uye yakaderera okisijeni kushandiswa mu biochemical process. Kuti isangane nezvinodiwa zveemission miyero uye kugadzirisa nharaunda ye aquaculture. Kushandiswa kwepolyaluminium chloride kunogona kuita mhedzisiro yekuchenesa mvura.

Polyaluminium chlorideinoita basa rakakosha mune aquaculture uye ine akawanda mabasa:

1. PAC inogona kukurumidza kuvandudza kunaka kwemvura, kuwedzera okisijeni yakanyungudika mumvura, kudzivirira eutrophication.

2. Inogona kubvisa mamwe utachiona uye mabhakitiriya akasungirirwa pane yakaturikwa yakasimba mumvura

3. Kana pane zvakawanda zvakanyanyisa zvinokonzerwa nehupenyu mumvura yemvura, nzira yekugadzirisa zvisikwa mumvura yemvura inonyanya kukosha, uye kushandiswa kwe polyaluminium chloride kunofanirawo kuva imwe yezvisarudzo zvinobudirira.

4. Kuberekesa muswe mvura kurapwa: Mvura yemhando yemadziva tsika ine huwandu hukuru hwezvinhu zvakasikwa zvakadai semasara etsika uye tsvina yehove, izvo zvinotungamirira kuderera kwekujekesa kwemvura uye eutrophication yehutano hwemvura. Kuyerera kwakananga kuchakonzera kusvibiswa kwezvakatipoteredza. Izvi zvinoda kuti dziva retsika yemvura icheneswe uye icheneswe, uye yobva yaburitswa kana kudzokororwa mushure mekusvika pazviyero zvekubuda. Kushandiswa kwepolyaluminium chloride kunogona kukurumidza kubatanidza, kuunganidza, uye flocculate colloidal particles izvo zvakaoma kupinza muzvikamu zvakakura uye zvinonaya mumvura, zvakanyanya kuderedza COD neBOD yemuviri wemvura uye nekuvandudza zvikuru kushanda kwekugadzirisa mvura yemuswe.

Polyaluminium chloride inokodzera mvura mbishi yemhando dzakasiyana siyana tembiricha uye yakafara pH renji.

Izvo zvinofanirwa kucherechedzwa kuti polyaluminium chloride inofanirwa kushandiswa muhuwandu hwakakodzera. Kushandisa zvakanyanya kunotungamirira kuhurombo husina kunaka uye hunogona kukonzera kuvhara kwegill yehove uye shrimp, uye haina kukodzera kushandiswa kwenguva refu. Panguva imwecheteyo, kana uchiishandisa, inofanirwa kurongeka nekuyerera kwetsvina kuti ibudise iyo agglomerates ye polyaluminium chloride kubva mudziva kuti iwane kubviswa zvachose.
