Mazwi akakosha: Kubvisa ruvara rweflocculant, chinhu chinobatsira kubvisa ruvara, mugadziri wechinhu chinobatsira kubvisa ruvara, Bvisa ruvara
Pakati penzizi dzakajeka nemakungwa ane ruvara rwebhuruu, pane boka re "vanochengetedza hunhu hwemvura" vasingafarirwi -- vanobvisa ruvara rwemvura. Kufanana nemubiki ane ruzivo, vanogona kushandura "muto" wakasviba kuita mvura yakachena sekristaro. Asi "mubiki" uyu ane hunhu hwake; chiyero, tembiricha, uye nzira yekukurunga zvese zvinosarudza mhedzisiro yehunhu hwemvura.
1. Chipimo: Chakawandisa, Chishoma; Chinozadza Mafashamo
Fungidzira kuwedzera mvura paunenge uchibika porridge: mvura shoma, porridge inonamira pasi; mvura yakawanda, uye inenge yakatetepa uye isina kunaka. Chiyero cheflocculant inobvisa ruvara chinodawo kudzorwa kwakarurama. Imwe fekitori yemachira, nekuda kwayo kuwana mhedzisiro nekukurumidza, yakawedzera chiyero chinokurudzirwa ne30%, zvichikonzera kwete chete kukundikana kuwana mhedzisiro yaidiwa asiwo mumaflocs akawandisa akadzikama nekukurumidza, zvichibvumira mamorekuru edhayi akasara mumvura kuti adzokezve se "hove dzakanyura mumambure." Imwe fekitori yekudhaya, yakanamatira zvakanyanya kune chiyero chinokurudzirwa che0.5‰, yakasarudza chiyero chakakodzera kuburikidza nemiedzo mitatu midiki, pakupedzisira ichidzikamisa ruvara rwetsvina pasi pemadhigirii gumi, ichisangana nechiyero chenyika cheClass I discharge.
2. Kupisa: Kodhi Yekumhanya Kwemakemikari
Mhedzisiro yekupisa pamhedzisiro yekudonha kwemavara eflocculant yakaita sekubikisa zai: mvura inotonhora inoda mwoyo murefu, nepo mvura inopisa ichikonzera kuonda nekukurumidza. Pamuchina wekugadzira mapepa kuchamhembe kweChina, apo tembiricha yemvura yakaderera kusvika 5°C munguva yechando, mainjiniya vakaderedza nguva yekudonha kubva pamaminitsi makumi matatu kusvika kumaminitsi gumi nemashanu nekudzora tembiricha yekunyungudika kweflocculant pa40°C, zvichibvumira macheni emamorekuru kukura zvizere. Panguva iyi, pafekitori yemagetsi kumaodzanyemba kweChina, panguva yekupisa kwakanyanya kwezhizha, vakawedzera retarder vakachengeta tembiricha ye reaction iri pasi pe25°C, vachidzivirira kuputsika kwefloc.
3. pH Kukosha: Unyanzvi hweAcid-Alkalinity Balance
pH kukosha, sekunge acidity kana alkalinity pa palette, inokanganisa zvakananga "hunhu" hwema flocculant. Imwe fekitori inogadzira chikafu, inorapa mvura yakasviba ine mafuta, yakaona kuti apo pH yaive pakati pe6 ne7, ma molecule e flocculant aigona kukwezva zvidimbu zvemafuta zvakaita semagineti. Zvisinei, apo pH yakadarika 8, ma floc aisununguka uye aipwanyika, uye mwero wekubvisa COD wakaderera ne40%. Nekuisa online pH monitor, mainjiniya akawana kudzora kwenguva chaiyo, vachidzikamisa COD yemvura iri pasi pe50 mg/L.
4. Kukurudzira: Kubvumira Mamorekuru Kutamba Waltz Yakakwana
Kumhanya nenguva yekukurunga kwakafanana nemutinhimira wekutamba: kukurumidza kupwanya mafloc, kunonoka kusingasanganise zvakakwana. Chigadziko chekuchenesa mvura yetsvina chekanzuru chakatora nzira yekukurunga "kukurumidza kunonoka": maminetsi maviri ekutanga akashandiswa kusanganisa nekukurumidza pa150 rpm kuti ive nechokwadi chekuti flocculant inobvisa ruvara uye tsvina yakabatana zvizere; maminetsi mashanu akatevera akashandiswa kusanganisa zvishoma nezvishoma pa30 rpm kuti floc ikure zvishoma nezvishoma. Musanganiswa uyu wekukurunga nekukurumidza nekunonoka wakawedzera saizi yefloc particle kubva pa50 μm kusvika pa200 μm, uye kumhanya kwekugadzikana kwakawedzera katatu.
5. Nguva: Unyanzvi hweKuchera Matongo
Nguva yekugadzika waini yakafanana nemaitiro ekugadzira waini: ipfupi uye waini haina simba, yakareba uye inorasikirwa nekutsva kwayo. Paki yemaindasitiri emakemikari yakawana kuburikidza nekuyedza kwekuenzanisa kuti apo nguva yekugadzika yakawedzerwa kubva pamaminitsi makumi matatu kusvika kumaminitsi makumi mana nemashanu, mwero wekubvisa SS wakawedzera kubva pa85% kusvika pa92%. Zvisinei, mushure memaminitsi makumi matanhatu, maflocs akagadzika akadzorerwa nekuda kwe "kugara kwenguva refu," zvichiita kuti tsvina idzoke zvakare.
Kubva pamupimo netembiricha kusvika pakukosha kwepH nekukurunga, chinhu chega chega cheflocculant chinobvisa ruvara ndicho chinosarudza kunaka kwemvura yekupedzisira. Sezvakataurwa nenyanzvi yekurapa mvura, "Hatisi kurapa mvura, asi tiri kutaurirana nemamorekuru." Kana donhwe rega rega remushonga rikawana nzvimbo yaro yakakodzera, tembiricha yega yega inenge yakakodzera, uye miniti yega yega yekudonha kwemvura yaitwa nemoyo murefu, mvura yakachena inozopedzisira yapupurira kuremekedza uku zvisikwa.
