Inyigo y'isuzuma ry'amazi yanduye mu nganda zikora amafi yo mu macupa

1, Amavu n'amavuko y'umushinga

Donghai Fisheries Co., Ltd., iherereye muri Peru, ni ikigo gishya gitunganya amafi yo mu macupa gifite ubushobozi bwo gukora toni 10000 buri mwaka. Amazi yanduye akorwa mu gihe cyo kuyatunganya afite imiterere isanzwe y’inganda: amazi yanduye asohoka buri munsi ni toni 800, amavuta agera kuri 350-400mg/L, arenze cyane amahame agenga ayo mazi, kandi arimo poroteyine nyinshi, imyanda y’amafi, n’ibikoresho bisigaye byo kuyatunganya. Igipimo cya COD kiri hagati ya 2500-3000mg/L igihe kirekire. Uburyo busanzwe bwa "grid+air flotation+biochemistry" bushobora gukuraho imyanda imwe n’imwe, ariko ubushobozi bwo kuyungurura umuvuduko ni buke, kandi ubushuhe bw’akayunguruzo ka filter bugera kuri 75%, ibyo bikaba bidatera gusa kwiyongera gukomeye kw’ikiguzi cyo gutunganya imyanda nyuma yaho, ahubwo n’amavuta ari mu myanda aracyahindagurika hagati ya 80-120mg/L, bigatuma bigorana kugera ku mahame ahamye.

2, Ibibazo by'ingenzi n'ibisubizo

Ingorane mu gutandukanya amavuta:

Amavuta ari mu mazi yanduye y’amafi yo mu bikombe aba mu mazi yakuwemo amashanyarazi n’ayo mu mazi asanzwe, kandi inzira gakondo zo kuzenguruka mu kirere ziragoye guca burundu amashanyarazi. Itsinda ry’umushinga ritanga uburyo bwoimashini ikoresha ikoranabuhanga rya hydraulic chamber filtering igenzurwa na porogaramu, ihujwe n'igitambaro cya polypropylene kidakoresha amavuta, kugira ngo amavuta agumane binyuze mu kuyungurura mu byiciro bitatu:

Icyiciro cyo mbere yo kuvurwa:Amazi yanduye abanza kuvurwa n'icyuma gitandukanya amavuta kugira ngo akureho amavuta areremba, hanyuma FeCl Ⅲ coagulant (igipimo cya 400mg/L) yongerwamo kugira ngo ihagarike guhagarara kwa colloidal, igakora flocs zifite ingano y'uduce turenze 50 μ m;

Icyiciro cyo gukanda ku mashini:Mu gihe cy'umuvuduko wa 0.8 MPa, urwego rw'imashini iyungurura rukorwa ku buso bw'igitambaro cy'iyungurura, rufata ibitonyanga by'amavuta bifite ingano irenga 1 μ m. Muri icyo gihe, imiterere y'urukiramende ku buso bw'icyuma cy'iyungurura ikomeza uburyo bwo gusuzuma amavuta ya emulsified mu buryo bwa mekanike;

Icyiciro cyo gukanda:Shyira igitutu cya 1.2MPa kuri keke y'urufunguzo ukoresheje sisitemu ya hydraulic, wongere ushyiremo amavuta, hanyuma ugabanye ubushuhe bwa keke y'urufunguzo munsi ya 55% n'ubushyuhe bwa peteroli munsi ya 8%.

Kunoza imikorere myiza yo gutandukanya ibintu bikomeye n'amazi:

Sisitemu yo gupakurura umukandara wo kohereza ibicuruzwa ikoresha ikoranabuhanga (ifite umuvuduko wa 800mm n'umuvuduko wo kohereza wa 0.5m/s) ikora imikorere yose yo kuyungurura, gupakurura no gutwara umuvuduko:

Isano ry'ubwenge:Nyuma yuko akamashini ka filter karangije akazi kamwe (iminota 45), isahani ya filter irakinguka ubwayo maze keke ya filter imanuka ijya ku mukandara w’imodoka bitewe n’imbaraga rukuruzi;

Igishushanyo mbonera kirwanya gufatana:Ubuso bw'umukandara utwara imizigo buterwa umuti wa PTFE, hamwe n'igikoresho gitera amazi umuvuduko mwinshi, kugira ngo hirindwe ko habaho kuziba kw'amazi guterwa no gufatana kw'akayunguruzo;

Imikoreshereze y'umutungo:Agace k’urufunguzo gafite ubushuhe bwa 55% gashobora gukoreshwa mu buryo butaziguye nk’ibikoresho fatizo byo kugaburira, kandi bivugwa ko gashobora kwinjiza amayuni agera ku 120000 mu bicuruzwa bikomoka ku bimera buri mwaka.

Imashini ikoresha filter yo mu bwoko bwa agasanduku:ifite sisitemu yo kugenzura ya PLC, ishobora guhindura umuvuduko w'amazi n'igihe cyo kuyakanda hakurikijwe ubwiza bw'amazi yinjira. Amakuru nyayo y'ibizamini agaragaza ko amashanyarazi akoreshwa mu gutunganya toni imwe y'amazi yanduye ari 0.85 kWh gusa, ari 40% munsi y'imashini zisanzwe zo gukata plate na frame filter;

Umukandara w'imodoka:Ifatanye neza n'aho imashini isohora ibikoresho, ikoresheje imiterere ya modular, ishobora gusimbuza vuba ibice byashaje, kandi igihe cyo kuyibungabunga cyongerwa kugeza ku mezi 6.

3,Ingaruka zo gushyira mu bikorwa n'inyungu z'ubukunguInyungu ku bidukikije:

Igipimo cy'amavuta mu myanda cyagabanutse kiva kuri 120mg/L mbere yo kuvugururwa kigera kuri 12mg/L, aho igipimo cyo gukuraho COD cya 97% n'igabanuka rya buri mwaka rya toni zigera kuri 28 z'imyuka ihumanya ikirere;

Ubushuhe bw'akayunguruzo bwagabanutseho 20%, kandi ingano y'imyanda ijyanwa hanze yagabanutse kuva kuri toni 60 ku kwezi igera kuri toni 22, bigabanya ikiguzi cyo gutwara ibintu ku kigero cya 70%.

imikorere mu bukungu:

Amafaranga yinjira ku mwaka ava mu ikoreshwa ry’umutungo wa filter cake ni 120000 yuan, agabanya 60% by’ikiguzi cy’ibikoresho bya filter press;

Igiciro cy’amashanyarazi n’imiti byagabanutseho 35%, bituma buri mwaka hagabanywa amafaranga agera kuri 250000 y’amayuan mu bikorwa byayo.

ibisubizo ku mibereho myiza y'abantu:

Nyuma yo gushyira mu bikorwa uyu mushinga, ikigo cyatsinze icyemezo cya ISO 14001 cyo gucunga ibidukikije, kiba igipimo ngenderwaho mu kurengera ibidukikije mu nganda zitunganya ibikomoka ku mazi zo mu gace ndetse no guteza imbere urwego rw'inganda zikora ibikomoka ku bidukikije mu karere.

4, Isuzuma ry'abakiriya

Mu gushyiraho uburyo bwo guhuza uburyo bwo gutunganya amazi yanduye n’umukandara wo mu bwoko bwa filter press, twakemuye burundu ikibazo cy’amazi yanduye cyari kimaze igihe kinini. Ubu, ntabwo dushobora gusa kugera ku gusohora amazi mu buryo buhamye kandi bukurikije amategeko, ahubwo n’agace k’icyuma gashobora no gukoreshwa nk’ibikoresho fatizo byo kugaburira amazi kugira ngo haboneke amafaranga menshi. Ubuhanga bw’ibi bikoresho burenze cyane ibyo byari byitezwe, kandi ikiguzi cyo kubikoresha no kubibungabunga cyagabanutseho hafi kimwe cya kabiri.
