Nekukwidziridzwa kwemaindasitiri, kubuda kwetsvina kwave nyaya hombe mukuchengetedzwa kwezvakatipoteredza. Nheyo yekuchenesa tsvina iri mukusarudzwa uye kushandiswa kweflocculantsmukucheneswa. Mumakore achangopfuura, yakakwirira-inoshanda polyaluminium chloride (PAC), sechinhu chakakosha flocculant, zvishoma nezvishoma yave "nyeredzi chigadzirwa" muindasitiri yekuchenesa tsvina nekuda kwekuita kwayo kwakanakisa uye tarisiro yakakura yekushandisa.
Polyaluminium chloride is inorganic polymer compound ine yakasimba flocculation effect. Inowanikwa ne polymerization reaction yealuminium chloride uye aluminium hydroxide pasi pemamiriro chaiwo. Zvichienzaniswa neyakagadzika aluminium salt flocculants (yakadai sealuminium sulfate, aluminium salt coagulant, nezvimwewo), yakakwirira-inoshanda polyaluminium chloride ine simba rakasimba rekubvisa zvinosvibisa, kunyanya kana ichibata nepamusoro turbidity uye inorema kusvibiswa kwemafuta. Kuita kwacho kunonyanya kutaridzika kana zvasvika pamhando yemvura. Yakave ichishandiswa zvakanyanya muminda yakawanda senge masewage yemasuwage, maindasitiri etsvina yekuchenesa, uye kuchenesa tsvina yemumba.
Zvakanakira zvemhando yepamusoro polyaluminium chloride
1. The flocculation effect inoshamisa
Yakakwirira-inoshanda polyaluminium chloride inogona kukurumidza kuumba nhamba huru yezvakanaka flocs mumvura, nekudaro zvinobudirira adsorbing yakamiswa yakasimba, colloidal zvinhu uye tupukanana mumvura. Inogona kukurumidza kushambadza uye kubvisa zvakamiswa zvimedu, girizi, heavy metal ions uye zvimwe zvinosvibisa mumvura. Kunyanya kana uchibata nemhando yemvura yakaoma, mhedzisiro yacho inokwirisa kupfuura yechinyakare aruminiyamu munyu flocculants. Mukugadziriswa kwetsvina, yakakwirira-inoshanda polyaluminium chloride inogona kuwedzera kukurumidza kugadzirisa kwesedimentation tangi munguva pfupi, nekudaro kupfupisa zvakanyanya kutenderera kwetsvina.
2.Wide yakawanda yekushandisa
High-efficiency polyaluminium chlorideinogona kuenderana nemhando dzakasiyana-siyana dzemhando yemvura, kusanganisira yakakwira turbidity mvura, yakakwira mafuta sewage, mvura ine simbi inorema, uye yakadzika-tembiricha yakaderera-turbidity mvura, ichiratidza kusimba kwakasimba. Inogona kubvisa nemazvo zvimedu zvakamiswa uye zvinosvibisa mumvura, uye inogona kushandiswa zvakanyanya mukuchenesa tsvina munzvimbo dzakasiyana senge manejimendi manejimendi, indasitiri, uye migodhi. Semuyenzaniso, mukurapwa kwetsvina yemumba, pulp mill wastewater, metallurgical wastewater, indasitiri yechikafu tsvina yemvura uye zvimwe zviitiko, yakakwirira-inoshanda polyaluminium chloride inogona kuwana yakanakisa kurapwa mhedzisiro.
3. Muyero wakaderera, kushanda kwepamusoro uye kuchengetedza simba
Yakakwirira-inoshanda polyaluminium chloride yakagadzirirwa kuwana shoma dosage uye nani flocculation maitiro. Muyero wepasi-turbidity i25-40% yealuminium sulfate, uye dosi ye-high-turbidity i10-25% yealuminium sulfate. Izvi hazvisi kungoderedza mutengo wekushandisa makemikari, asiwo zvinoderedza kushandiswa kwesimba uye sludge mukugadzirisa tsvina. Nekuda kwekuderera kwayo kwealuminium yakasara, inoderedza kusvibiswa kwechipiri kwemitumbi yemvura uye inoderedza zvakanyanya mutengo wakazara wekuchenesa tsvina. Naizvozvo, chave chishandiso chakakosha chekuchengetedza mari uye nekuvandudza kugona mukushandisa zvinoshanda.
4. Kushamwaridzana nemhoteredzo
Kushandiswa kwepamusoro-kushanda kwepolyaluminium chloride kune zvishoma zvinokanganisa zvakatipoteredza uye zvakasara zvealuminium. Kana ichienzaniswa nemamwe makemikari anoyerera, polyaluminium chloride haina njodzi uye ine zvishoma zvinokanganisa pH neTA yemvura inoyerera, saka kudiwa kwemakemikari kugadzirisa pH neTA kunodzikiswa. Kunyanya mukurapwa kwetsvina yakakura uye mapurojekiti ekuchengetedza kwezvakatipoteredza, yave sarudzo yakasvibira uye ine hushamwari.
5. Inokodzera kupisa kwakadzika uye yakakwirira turbidity kurapwa kwemvura
Kuchenesa mvura mumwaka wakaderera-tembiricha idambudziko rinowanzoitika. Kunyanya munguva yechando inotonhora, kushanda kwezvizhinji zvetsika flocculants kuchaderedzwa zvikuru. Nekudaro, yakakwira-inoshanda polyaluminium chloride inogona kuramba ichichengetedza yakakwira flocculation mhedzisiro pasi peyakadzika-tembiricha mamiriro. Uye zvakare, kana turbidity yemvura yakakwira, PAC inoratidzawo simba rekugadzirisa uye inogona kunyatsobvisa yakamiswa zvimedu uye colloidal zvinhu mumvura. Kumvura ine kusvibiswa kwemafuta anorema, yakakwirira-inoshanda polyaluminium chloride zvakare ine yakanaka kwazvo yekubvisa mhedzisiro.
6. Shandura kune zvakasiyana-siyana pH kukosha mazinga
Yakakwirira-inoshanda polyaluminium chloride ine yakasimba kuchinjika kune shanduko mumvura pH uye inogona kunyatsoshanda muhupamhi pH renji. Kazhinji kutaura, PAC inogona kuchengetedza yakanaka flocculation mhedzisiro mumvura ine yakaderera (acidic) kana yepamusoro (alkaline) pH kukosha, iyo inowedzera kuwedzera kushanda kwayo pasi pemamiriro akasiyana emhando yemvura. 5.0-9.0 vs 5.5-7.5
7. Kuvandudza sedimentation kunyatsoshanda uye kuderedza sludge volume
Yakakwirira-inoshanda polyaluminium chloride inobatsira kukurumidza kugadzika kwezvimedu zvimedu mutsvina uye inovandudza kushanda zvakanaka kwetangi rekuisa sedimentation nekuvandudza density uye kugadzikana kwemaflocs. Mukuwedzera, nekuda kwehupamhi hwepolymerization ye-high-efficiency polyaluminium chloride, flocs dzakaumbwa dzakasimba uye dzinogara nekukurumidza, nokudaro kuderedza kuwanda kwemarara anogadzirwa. Izvi zvakakosha zvikuru kune kunotevera kurapwa uye kuraswa kwemarara, uye zvinogona kuderedza mutengo uye kuoma kwekurapwa kwemarara.
Mienzaniso yekushandiswa kwepamusoro-inoshanda polyaluminium chloride mukurapwa kwemvura yetsvina
1. Kugadziriswa kwesuweji yeMaspala
Mumunda wekugadziriswa kwesuweji yemasuwage, yakakwirira-inoshanda polyaluminium chloride inogona kushandiswa zvakanyanya mu pretreatment uye yechipiri kurapa matanho emiti yemvura. Inogona kunyatso kubvisa zvakamiswa zvakasimba, colloidal zvinhu, mabhakitiriya uye zvimwe tupukanana mumvura, kunatsiridza kunaka kwemvura, uye kupa yemhando yepamusoro sosi yemvura yekutevera kurapwa kwebiological. PAC yave imwe yeakanyanya flocculants mumafekisheni ekuchenesa tsvina mumaguta mazhinji kumba nekune dzimwe nyika.
2.Industrial wastewater treatment
Mumunda wekugadziriswa kwemvura yetsvina yeindasitiri, yakakwira-inoshanda polyaluminium chloride inoshandiswa zvakanyanya. Iine maitiro akanaka ekurapa pamvura yakasviba yeindasitiri kubva pakudhinda nekudhaya, kugadzira mapepa, matehwe, electroplating uye mamwe maindasitiri, uye inogona kunyatsobvisa zvinosvibisa zvakaita seruvara, COD neBOD. Semuenzaniso, mune simbi, simba remagetsi, indasitiri yemakemikari, kugadzira mapepa, kugadzira chikafu uye mamwe maindasitiri, PAC inogona kubatsira kubvisa zvinorema simbi, mafuta mavara, akaturikwa zvimedu uye zvimwe zvinosvibisa mumvura. Kunyanya kana ichirapa mvura yetsvina ine mafuta, PAC yakaratidza kugona kwayo kwekubvisa mafuta uye inogona kuderedza zvakanyanya mafuta ari mumiviri yemvura.
3. Migodhi yekuchenesa mvura
Mumunda wekugadziriswa kwemvura yakasviba yemigodhi, yakakwirira-inoshanda polyaluminium chloride inogona kunyatsobvisa zvicherwa, sediment uye zvimwe zvakamiswa mumvura, zvichipa rutsigiro rwekudzokorodza kwemvura uye kudzoreredza ecological munzvimbo dzemigodhi. Sezvo hutano hwemvura munzvimbo dzemigodhi hwakaoma uye kazhinji hune huwandu hwakawanda hwezvakarembedzwa zvakasimba uye simbi inorema, kushanda kwepamusoro kwepamusoro-soro ye polyaluminium chloride inonyanya kukosha mumhando iyi yekuchenesa mvura.
Kazhinji,high-efficiency polyaluminium chloride, seyakanakisa flocculant yekuchenesa tsvina, ine zvakakosha zvehunyanzvi uye zvakatipoteredza zvakanakira. Kunyanya kana iri huturu hwepamusoro, hunyoro hwemvura hwakaoma, uye kusvibiswa kwemafuta anorema, inogona kuwana mamwe maitiro ekurapa.
