1, Imvelaphi yeProjekthi
I-Donghai Fisheries Co., Ltd., esePeru, yinkampani yanamhlanje yokuvelisa iintlanzi ezifakwe emakhayeni enomthamo wonyaka wemveliso yeetoni ezili-10000. Amanzi amdaka aveliswa ngexesha lenkqubo yawo yokuvelisa aneempawu eziqhelekileyo zoshishino: ukukhutshwa kwamanzi amdaka imihla ngemihla malunga neetoni ezingama-800, umxholo weoyile uphezulu njenge-350-400mg/L, udlula kakhulu imigangatho yokukhutshwa, kwaye ikwanayo neproteni eninzi, inkunkuma yeskali seentlanzi, kunye nezinto zokucubungula eziseleyo. Uxinzelelo lwe-COD luphakathi kwe-2500-3000mg/L ixesha elide. Inkqubo yendabuko "yegridi+yomoya ojikelezayo+i-biochemistry" inokususa ezinye izinto ezingcolisayo, kodwa ukusebenza kakuhle kwenkqubo yokucoca uxinzelelo kuphantsi, kwaye umxholo wokufuma wekhekhe lokucoca uphezulu njenge-75%, oku kungakhokeleli nje kuphela ekonyukeni okukhulu kweendleko zonyango lwenkunkuma elandelayo, kodwa nomxholo weoyile kwinkunkuma usatshintshatshintsha phakathi kwe-80-120mg/L, okwenza kube nzima ukufikelela kwimigangatho ezinzileyo.
2, Imingeni ephambili kunye nezisombululo
Ubunzima bokwahlulwa kweoyile:
Ioyile ekwiintlanzi ezisele zityiwe emanzini ikhona kwiimeko ezixutyiweyo nezixutyiweyo, kwaye iinkqubo zemveli zokudada emoyeni kunzima ukuziqhekeza ngokupheleleyo. Iqela leprojekthi lazisaumatshini wokucoca wegumbi le-hydraulic olawulwa yinkqubo, idityaniswe nelaphu lesihluzi se-polypropylene esinganyangekiyo kwioyile, ukuze kugcinwe ioyile ngokuhluzwa ngamanqanaba amathathu:
Inqanaba langaphambi konyango:Amanzi amdaka aqale aphathwe ngesixhobo sokwahlula ioyile ukususa ioyile edadayo, aze emva koko kongezwe i-FeClⅢ coagulant (umthamo we-400mg/L) ukuze kuphazamiseke uzinzo lwe-colloidal, kwenze ii-flocs ezinobukhulu bee-particle>50 μ m;
Inqanaba lokucinezela isihluzo:Phantsi koxinzelelo lokutya lwe-0.8 MPa, umaleko wekhekhe lesihluzo oguqukayo wenziwa phezu komphezulu welaphu lesihluzo, othintela ngokwasemzimbeni amathontsi eoli anobukhulu obungaphezulu kwe-1 μ m. Kwangaxeshanye, isakhiwo esingqukuva kumphezulu wepleyiti yesihluzo siqinisa ukuvavanywa koomatshini kweoyile exutyiweyo;
Inqanaba lokucinezela:Faka uxinzelelo lwe-1.2MPa kwikhekhe lesihluzo ngenkqubo ye-hydraulic, ukhuphe ioyile ngakumbi, kwaye ekugqibeleni unciphise umxholo wokufuma wekhekhe lesihluzo ube ngaphantsi kwe-55% kunye nomxholo weoyile ube ngaphantsi kwe-8%.
Ukuphuculwa kokusebenza kakuhle kokwahlulwa kolwelo oluqinileyo:
Inkqubo yebhanti yokuhambisa exhasayo ezenzekelayo (ene-bandwidth ye-800mm kunye nesantya sokuhambisa se-0.5m/s) yenza inkqubo epheleleyo yokuziqhelanisa nokuhluza uxinzelelo, ukukhupha, kunye nokuthuthwa:
Unxibelelwano olukrelekrele:Emva kokuba umatshini wokucoca ugqibe umjikelo omnye wokusebenza (malunga nemizuzu engama-45), ipleyiti yokucoca ivuleka ngokuzenzekelayo kwaye ikhekhe lokucoca lityibilika liye ebhantini lokuhambisa ngenxa yomxhuzulane;
Uyilo oluchasene nokunamathela:Umphezulu webhanti yokuhambisa uphathwa ngengubo ye-PTFE, edityaniswe nesixhobo sokutshiza amanzi esinoxinzelelo oluphezulu, ukuze kuthintelwe ukuhanjiswa kokuvaleka okubangelwa kukunamathela kwekhekhe lesihluzi;
Ukusetyenziswa kwezixhobo:Ikhekhe lesihluzo elinomthamo wokufuma we-55% lingasetyenziswa ngokuthe ngqo njengezinto zokutya, kwaye kuqikelelwa ukuba linokuvelisa malunga ne-120000 yuan kwingeniso yemveliso eshiyekileyo ngonyaka.
Umatshini wokucoca isihluzi sohlobo lwebhokisi:Ixhotyiswe ngenkqubo yolawulo ye-PLC, ingazilungisa ngokuzenzekelayo uxinzelelo lokutya kunye nexesha lokucinezela ngokwemigangatho yamanzi okungena. Idatha yovavanyo lokwenyani ibonisa ukuba ukusetyenziswa kombane ekucoceni itoni enye yamanzi amdaka yi-0.85 kWh kuphela, engaphantsi ngama-40% kunee-presents zesiqhelo zepleyiti kunye neefreyimu zesihluzi;
Ibhanti lokubonisa:iqhagamshelwe ngaphandle komthungo kwizibuko lokukhupha le-filter press, isebenzisa uyilo lwemodyuli, inokutshintsha ngokukhawuleza iindawo ezigugileyo, kwaye umjikelo wokugcinwa wolulwe ukuya kwiinyanga ezi-6.
3,Isiphumo sokuphunyezwa kunye neenzuzo zoqoqoshoIingenelo zokusingqongileyo:
Umxholo weoyile kwindawo engcolileyo wehlile ukusuka kwi-120mg/L ngaphambi kokuhlaziywa ukuya kwi-12mg/L, kunye nezinga lokususwa kwe-COD eliyi-97% kunye nokwehla konyaka malunga neetoni ezingama-28 zokukhutshwa kweoyile;
Umthamo wokufuma wekhekhe lesihluzo wehle nge-20%, kwaye ubungakanani bodaka oluthuthwa ngaphandle lwehle ukusuka kwiitoni ezingama-60 ngenyanga ukuya kwiitoni ezingama-22, nto leyo enciphisa iindleko zothutho malunga ne-70%.
ukusebenza koqoqosho:
Ingeniso yonyaka evela ekusetyenzisweni kwezixhobo ze-filter cake yi-120000 yuan, ihlawula i-60% yeendleko zokwehla kwexabiso lezixhobo ze-filter press;
Iindleko ezidibeneyo zokusetyenziswa kombane kunye namayeza ziye zehla ngama-35%, nto leyo ekhokelele ekongeni imali yonyaka emalunga nama-250000 yuan kwiindleko zokusebenza.
iziphumo zentlalo:
Emva kokuphunyezwa kwale projekthi, eli shishini liphumelele isiqinisekiso senkqubo yolawulo lokusingqongileyo se-ISO 14001, saba ngumlinganiselo wokhuseleko lokusingqongileyo kwishishini lokucubungula imveliso yasemanzini lasekuhlaleni kwaye likhuthaza ukuphuculwa kwenqanaba lokuvelisa izinto eziluhlaza kummandla.
4, uphononongo lwabathengi
Ngokuzisa isisombululo esidibeneyo sebhokisi yokushicilela isihluzo kunye nebhanti yokuhambisa, siyisombulule ngokupheleleyo ingxaki yexesha elide yonyango lwamanzi amdaka. Ngoku, asinakukwazi nje kuphela ukukhupha amanzi ngendlela ezinzileyo nehambelanayo, kodwa ikhekhe lesihluzo linokusetyenziswa njengezinto zokutya ukuze kufumaneke ingeniso eyongezelelweyo. Inqanaba lobukrelekrele besi sixhobo lidlula kakhulu ulindelo, kwaye iindleko zokusebenza nokugcinwa kwazo zincitshisiwe phantse ngesiqingatha.
