Wastewater Treatment Process Overview

1.Pre-kurapwa

● Tsanangudzo: Pre-kurapwa kunosanganisira nzira dzemuviri dzekubvisa zvidimbu zvakakura uye marara anoyangarara kubva mumvura yetsvina kuchengetedza midziyo yekurapa inotevera. Midziyo yakakosha inosanganisira skrini, makamuri egrit, uye mabheseni ekuenzanisa.

● Function: Inobvisa zvakaturikwa zvakasimba, jecha, uye marara makuru, homogenizes uwandu hwemvura uye kunaka, uye inogadzirisa pH mazinga.

2.Primary Treatment

● Tsanangudzo: Kurapa kwekutanga kunonyanya kushandisa matangi ekubvisa marara kuti abvise marara akamiswa kubva mumvura yetsvina kuburikidza nekugadzirisa giravhiti.

● Function: Kuwedzera kunoderedza zvakamiswa zvinyoro uye zvimwe organic zvinhu, kurerutsa mutoro pamatanho ekurapa anotevera.

3.Secondary Treatment

● Tsanangudzo: Kurapwa kwechipiri kunonyanya kushandisa nzira dzebhayoloji, senge activated sludge process uye Sequencing Batch Reactors (SBR), apo tupukanana tunogadzika nekubvisa yakawanda yeorganic matter, nitrogen, uye phosphorus.

● Function: Inoderedza zvakanyanya organic content uye inobvisa nitrogen uye phosphorus, inovandudza kunaka kwemvura.

4.Kurapa Kwepamusoro

● Tsanangudzo: Kurapwa kwepamusoro kunowedzera kubvisa zvinosvibisa zvakasara mushure mekurapa kwechipiri kuti uwane zviyero zvepamusoro zvekubuda. Nzira dzakajairika dzinosanganisira coagulation-sedimentation, filtration, adsorption, uye ion exchange.

● Function: Inobvisa zvinosvibisa, zvakaturikwa zvakasimba, uye organic zvinhu, kuona kuti mvura yakacheneswa inoenderana neyakaomarara.

5.Sludge Treatment

● Tsanangudzo: Kurapwa kwesludge kunoderedza kuwanda kwedhaka uye kudzikamisa organic zvinhu kuburikidza nematanho akaita sekukora, kugaya, kubvisa mvura, uye kuomesa. Dora rakacheneswa rinogona kupiswa kana kuumbwa manyowa.

● Function: Inoderedza huwandu hwematope, inodzikisa mari yekurasa, uye inodzoreredza zviwanikwa.

Kushandiswa kweHeat Exchangers muWastewater Treatment

1.Anaerobic Digestion

● Process Point: Digesters

● Application: Welded plate heat exchangersanoshandiswa kuchengetedza tembiricha yakakwana (35-55 ℃) mune anaerobic digesters, kusimudzira kuita kwehutachiona uye organic matter kushatiswa, zvichikonzera kugadzirwa kwebiogas.

● Zvakanakira:

·High Temperature uye Pressure Resistance: Inokodzera nzvimbo yepamusoro-yekushisa yeanaerobic digestion.

·Corrosion Resistance: Yakagadzirwa ne-corrosion-resistant materials, yakanakira kubata marara anoparadza.

·Kufambisa Kupisa Kunoshanda: Compact dhizaini, yakanyanya kupisa kupisa kunyatsoita, inosimudzira anaerobic digestion kuita.

● Zvakaipa:

·Complex Maintenance: Kuchenesa nekugadzirisa kwakaoma, zvinoda hunyanzvi hunyanzvi.

·High Initial Investment: Mutengo wekutanga wepamusoro uchienzaniswa neyakagadzika kupisa.

2.Sludge Heating

● Process Points: Sludge thickening matangi, dewatering units

● Application: Zvese zviri zviviri gasketed uye welded plate heat exchangers anoshandiswa kupisa sludge, kunatsiridza kudzikisa mvura.

● Zvakanakira:

·Gasketed Heat Exchanger:

·Easy Disassembly uye Kuchenesa: Kugadzirisa kwakareruka, kwakakodzera kune yakanyatso kuchena sludge.

· Yakanaka Heat Transfer Performance: Flexible dhizaini, inobvumira kugadziriswa kwenzvimbo yekutsinhanisa kupisa.

·Welded Heat Exchanger:

·High Temperature uye Pressure Resistance: Inokodzera kudziya kwepamusoro-soro uye yakakwirira-kumanikidza nharaunda, zvinobudirira kubata viscous uye corrosive sludge.

·Compact Structure: Kuchengetedza nzvimbo nepamusoro-soro kutamisa kupisa.

● Zvakaipa:

·Gasketed Heat Exchanger:

·Gasket Kuchembera: Inoda periodic gasket kutsiva, kuwedzera mari yekugadzirisa.

·Haikodzeri Kupisa Kwepamusoro uye Kudzvinyirira: Hupenyu hupfupi munzvimbo dzakadai.

·Welded Heat Exchanger:

·Complex Kuchenesa uye Maintenance: Inoda hunyanzvi hwekuita basa.

·High Initial Investment: Yepamusoro kutenga uye kuisa mari.

3.Bioreactor Temperature Control

● Process Points: Aeration matangi, biofilm reactors

● Application: Gasketed plate heat exchangers inodzora tembiricha mumabioreactors, kuve nechokwadi chekwakaringana microbial metabolic mamiriro uye kunatsiridza organic kushatisa zvinhu.

● Zvakanakira:

·High Heat Transfer Kubudirira: Nzvimbo yakakura yekutsinhanisa kupisa, inokurumidza kugadzirisa tembiricha.

·Easy Maintenance: Yakanaka disassembly uye kuchenesa, yakakodzera maitiro anoda kugara achigadziriswa.

● Zvakaipa:

·Gasket Kuchembera: Inoda kuongororwa nguva nenguva uye kutsiva, kuwedzera mari yekugadzirisa.

·Haikodzeri Corrosive Media: Kusagona kuramba kune corrosive media, izvo zvinoda kushandiswa kwezvinhu zvinodzivirira.

4.Process Cooling

● Process Point: High-tembiricha tsvina yemvura inopinza

● Application: Gasketed plate heat exchangers inotonhorera yakakwirira-tembiricha yetsvina kuchengetedza inotevera kurapa michina uye kunatsiridza kurapa kwakanaka.

● Zvakanakira:

·Kufambisa Kupisa Kunoshanda: Nzvimbo huru yekutsinhanisa kupisa, inokurumidza kuderedza kupisa kwemvura yakasviba.

·Compact Structure: Kuchengetedza nzvimbo, nyore kuisa uye kushanda.

·Easy Maintenance: Yakanaka disassembly uye kuchenesa, yakakodzera kuyerera kukuru kwemvura yetsvina kurapwa.

● Zvakaipa:

·Gasket Kuchembera: Inoda periodic gasket kutsiva, kuwedzera mari yekugadzirisa.

·Haina Kukodzera Yakanyanya Corrosive Media: Kusagona kuramba kune corrosive media, izvo zvinoda kushandiswa kwezvinhu zvinodzivirira.

5.Kugeza Mvura Inopisa

● Process Point: Girisi kubvisa zvikamu

● Application: Welded plate heat exchangers inoshandiswa kugeza uye kutonhora kwepamusoro-tembiricha uye ine mafuta tsvina yemvura, kubvisa girisi nekuvandudza kushanda kwekurapa.

● Zvakanakira:

·High Temperature uye Pressure Resistance: Inokodzera nzvimbo dzepamusoro-tembiricha uye dzakakwirira-dzinomanikidza, kubata mafuta ane mafuta uye yakakwirira-yepamusoro-tembiricha tsvina zvinobudirira.

·Strong Corrosion Resistance: Yakagadzirwa nemhando yepamusoro-inodzivirira corrosion zvinhu, kuve nechokwadi chekushanda kwakagadzikana kwenguva refu.

·Kufambisa Kupisa Kunoshanda: Kunyanya kupisa kupisa kushanda zvakanaka, nekukurumidza kuderedza kupisa kwemvura yetsvina uye kubvisa girizi.

● Zvakaipa:

·Complex Maintenance: Kuchenesa nekugadzirisa kwakaoma, zvinoda hunyanzvi hunyanzvi.

·High Initial Investment: Mutengo wekutanga wepamusoro uchienzaniswa neyakagadzika kupisa.
