Kambani yekugadzira chikafu chepakati nepakati inotarisa pakugadzira chikafu chakakangwa nenyama, uye inogadzira mvura yakawanda ine mafuta akawanda mukugadzirwa kwayo, ine zvinhu zvinosvibisa zvakaita sezvimedu zvekudya, mafuta emhuka nemiti nemapuroteni. Hunhu hwemvura yetsvina hunochinja-chinja zvikuru, huwandu hwemafuta hwakakwira, uye kubudiswa kwayo zvakananga kuri nyore kukonzera kuvharika kwemapaipi uye kupwanywa kwemvura. Zvichienderana nekuverenga kwechiyero chekugadzira kwekambani, kubudiswa kwemvura yetsvina i2.5m³/awa. Kuti zvizadzise zvinodiwa zvekuchengetedzwa kwezvakatipoteredza uye kuwana budiriro inoenderera mberi, mabhizinesi anofanirwa kuvaka sisitimu yekurapa mvura yetsvina inoshanda uye yakagadzikana ine nhanho diki yekuona kuti tsvina inosvika padanho rakakodzera uye kuderedza kurasirwa kwetsvina.
Ii. Zvinhu zvinorwadza vatengi
Mafuta akawanda akaoma kubata nawo: mafuta ari mumvura yakasviba ari ≥80mg/L, uye nzira yekurapa yakajairika haina simba rekuparadzanisa mafuta anosanganiswa ne emulsified, izvo zviri nyore kukonzera kuvharika kwemayuniti ekurapa anotevera, kushanda zvishoma, uye mari yakawanda yekugadzirisa.
Kugona kwekugadzirisa michina yekutanga hakuna kukwana: michina iri nyore iripo haigone kuenzana nezvinodiwa pakuburitsa mvura ye2.5m³/awa, uye hunhu hwemvura inoyerera hunochinja-chinja zvakanyanya, zvichikonzera njodzi yekudarika mwero wekuchengetedza nharaunda.
Zvirambidzo zviviri zvenzvimbo yekurasa marara: chirimwa ichi chine nzvimbo diki, chinoda nzira yekurapa yakamanikana uye inoshanda, uye kugadzirisa dambudziko rekurasa marara etsvina kudzivirira kusvibiswa kwemamwe marara.
3. Mhinduro dzakagadziriswa
Zvichienderana nehunhu hwemvura ine mafuta akawanda uye zvinodiwa chaizvo nevatengi, nzira yakabatana yekurapa "pretreatment + coagulation precipitation + diaphragm pressure filtration uye kushaya mvura mumuviri" yakagadzirwa, uye nzira yekurapa nekubvisa mvura muma pharmacy inogadziriswa kuti ibvise mafuta zvakanaka uye ishande zvakanaka.
1. Kuyerera kwemaitiro
Padanho rekutanga rekugadzirisa, mvura yakasviba inotanga yapfuura nepagrid yemuchina kuti ibvise zvidimbu zvakakura zvechikafu, yozopinda mu advection oil trap, uye musimboti wekuparadzanisa mafuta unoshandiswa kubvisa mafuta anotsvedza (removal rate ≥60%), izvo zvinoderedza zvakanyanya mutoro wekurapa unotevera.
Danho rekuvhara mvura nekuputika: Mushure mekugadzirisa mvura isati yatanga, mvura yakasviba inopinda mutangi rekuvhara mvura, uye PAC (polyaluminum chloride) nePAM (polyacrylamide) zvinowedzerwa kuburikidza nepombi yekuyera chaiyo. PAC inoparadza mamiriro emafuta e emulsion, PAM inokurudzira kuungana kwe flocs, ichigadzira ma flocs ane mafuta ari nyore kudonha, uye inoita kuti mafuta, mvura uye zvakasimba zviparadzaniswe zvakanaka muzvikamu zvitatu.
Kupatsanurwa kwemvura yakasimba uye kushaya mvura: mushure mekuomeswa, mvura yakasviba inoyerera ichipinda mutangi remvura kuti iparadzanise matope nemvura, uye mvura inobuda muvhu inoyerera kusvika padanho repamusoro. Dota rine mafuta riri pasi rinopombwa muchina wekuchenesa diaphragm, uye hunyoro hwemvura inobuda muvhu hunoderedzwa kusvika pasi pe60% nekuda kwekuwedzera kwedhiragm uye kupera mvura mumuviri, zvichiita keke remvura yakasimba yekutakura nekurasa kunze. Filtrate yefirita yemhepo inodzoserwa kuyuniti yekurapa kuti mvura yakasviba ichengetwe yakavharwa mukuita kwese.
2. Zvishandiso zvinokosha uye maparamita ekushanda
Pakati penzira yekugadzirisa inoshandisa michina yekuchenesa mvura ine simba rekugadzirisa re2.5m³/awa, uye muchina wekusefa wediaphragm we30㎡.
Chipimo chePAC: 50-80mg /L, PAM chipimo: 3-5mg /L, zvichienderana nekugadzirwa kwemvura munguva chaiyo, kuti pave nemhedzisiro yakanaka yekurapa;
Sisitimu iyi ine hurongwa hwekudzora hwakangwara kuti iite otomatiki mashandiro ekushandisa mishonga, kubvisa tsvina nezvimwe zvinongedzo, uye kuderedza simba rekushanda nemaoko.
Iv. Mhedzisiro yekushanda kwepurojekiti
Hunhu hwetsvina hwakagadzikana uye hunoenderana nezvinodiwa: mushure mekunge sisitimu yatanga kushanda, huwandu hwemafuta etsvina hunoderedzwa kusvika pasi pe5mg/L, uye zvimwe zviratidzo zvinoenderana nezvinodiwa nemunzvimbo yacho;
Kuderedza tsvina kunoshamisa: chidhindo chediaphragm filter chinoderedza hunyoro hwetsvina kusvika pasi pe60%, uye huwandu hwetsvina hunoderedzwa neinenge 70%, izvo zvinoderedza zvakanyanya mutengo wekurasa tsvina;
Kushanda uye kugadzirisa kuri nyore: dhizaini yakabatanidzwa inofukidza nzvimbo diki, mwero wepamusoro we otomatiki, mutoro mudiki wekugadzirisa zuva nezuva, kushanda kwakasimba uye kwakavimbika kwenguva refu.
V. Pfupiso yenyaya
Kuburikidza nekugadzirwa kwakagadzirwa kare, kuyerera kwemvura inoyerera ichivharika uye nzira yekubvisa mvura kubva muropa iri mu diaphragm, nyaya iyi inogadzirisa matambudziko ekurapa mvura yakasviba ine mafuta akawanda mumakambani ekugadzira chikafu. Sisitimu iyi inoshanda zvakanyanya, yakagadzikana uye yakamanikana, iyo isingangovimbisi chete kuti tsvina inosvika padanho rayo, asiwo inoita kuti tsvina ideredzwe uye iraswe, ichipa vatengi mhinduro dzekuchengetedza nharaunda nemari uye dzinogoneka.
