Changshengqiao inzvimbo yekurasa tsvina yemupata ine nzvimbo inosvika 690,642 m. ³ , nzvimbo yekurasira ivhu inosvika 379,620 m ³ uye dhizaini inokwana mamirioni gumi nemana m ³ . Nzvimbo yekurasira yaiswa pakupera kwaChikunguru 2003 uye yakavharwa pakupera kwa2016. Yange iri kuvharwa kwakadzorwa uye kudzoreredzwa kubva 2018.

Nzvimbo iripo yekurapa leachate paChangshengqiao Landfill yakagadzirwa se1,730 ton/d nzvimbo, ine mazana mana ematani/d MBR+DTRO system uye 1,330 ton/d STRO yekurapwa kwechimbichimbi. Parizvino, iyo MBR+DTRO masisitimu inoburitsa matani zana eiyo leachate concentrate pazuva, uye STRO nzvimbo inoburitsa matani mazana mana ekusimbisa pazuva. Iyo inogadzirwa leachate concentrate inosanganiswa uye inochengetwa mudziva rekuenzana mukati menzvimbo yekurasira, iyo inenge 38,000 m. ³ zvakachengetwa mukati mekurasira marara uye anenge 140,000 m ³ dzinochengetwa kunze kwerashi. Kuchengetedzwa kwenzvimbo yesaiti kunenge kuzara, nenjodzi dzakatanhamara dzezvakatipoteredza.

Iyo leachate concentration treatment system muchirongwa ichi inonyanya kuumbwa nembiri, imwe ndeye MBR+DTRO inonangana neyepamusoro biochemical treatment, uye imwe yacho STRO concentrate pasina biochemical treatment. Unhu hwemvura hwezviviri izvi hunosiyana zvakanyanya, uye chinhu chekurapa chepurojekiti iyi chakasanganiswa.

Pedzisa leachate yevasungwa kurapwa mumarara mukati memwedzi ye3 yekushanda kwepamutemo.

Pedzisa leachate yevasungwa kurapwa mukati uye kunze kweravha mukati memwedzi ye18 yekushanda kwepamutemo.

Maitiro matsva eleachate anotarisa panguva imwe chete zuva nezuva.

Zvinoenderana neshumo yemhando yemvura yesampling yemvura uye ruzivo rwekambani yedu mumapurojekiti akafanana, dhizaini yemhando yemvura yeprojekiti iyi ndeiyi:

ZLD 1,000 m³/d kurapwa maitiro
Pretreatment + Concentration + Evaporation +Desiccation

Iyo concentrate muequalization tank ine yakamiswa solids (SS) uye zvakare ine yakanyanya kuoma. Ose ari maviri anofanirwa kubviswa nekupfava uye TUF pretreatment.

Mvura inobva mukupfava inobatwa nechinhu membrane. Kusarudzwa kwe membrane kunoenderana neakakodzera molecular uremu. Zvinoenderana nemhedzisiro yekuyedza, iyo yakakodzera molecular uremu inogona kusarudzwa. Muchiitiko ichi, chikamu che colloid uye macromolecular organic zvinhu zvinogona kurambwa nesarudzo yakasarudzwa membrane pasina kuramba kuoma uye salinity. Izvi zvinogona kupa nharaunda yakanaka yeHPRO neMVR kushanda. Kunze kwezvo, iyo sisitimu inokwanisa kudzoreredza 90-98% ine yakaderera yekushanda kumanikidza nekuda kweiyo zvinhu membrane maitiro. Uyezve, huwandu hushoma hwekuisa pfungwa hunowedzera kurapwa ne desiccation.

Mvura inobva mumemtrane inowedzerwa neHPRO. Sezvo HPRO yakagamuchira anti-pollution disc membrane module, inogona kutarisisa zvakanyanya mvura yakasvibira, ichidzikisa huwandu hwemvura yakabuda. Nekudaro, iyo yese yekudyara uye mutengo wekushandisa unogona kuchengetwa.

Hunhu hwepermeate kubva kune zvinhu membrane yakanaka kudzikisa huwandu hweanti-foam agent inoshandiswa muMVR evaporation system. Izvi zvinogona kunyatso bvisa furo chiitiko. Mukuwedzera, munyu haugoni kuputirwa ne organic matter, iyo inobatsira kune yakagadzikana uye inopfuurira evaporation crystallization. Kunze kwezvo, sezvo MVR system inogona kushanda mumamiriro ane acidic nekumanikidza kwakashata uye tembiricha yakaderera, iyo scaling uye corrosion chiitiko chinogona kudzivirirwa. Zvakare, furo rakaoma kuburitsa, zvichitungamira kune yakanaka evaporation condensate mhando. Iyo MVR permeate inoyerera ichidzokera kune membrane system kuti iwedzere kurapwa isati yaburitswa. Iyo brine kubva kuMVR inobatwa ne desiccation.

Kune marudzi matatu emarara anogadzirwa muchirongwa ichi, anoda kurapwa. Ndiwo inorganic sludge kubva pretreatment, brine sludge kubva evaporation crystallization uye matope kubva desiccation.

Kondirakiti yakasainwa muna Mbudzi, 2020. Midziyo ine 1000 m³/d yekurapisa simba yakaiswa uye yakagamuchirwa muna Kubvumbi, 2020. Chirongwa cheJiarong Changshengqiao yeZLD chirongwa chinogona kutorwa sechiyero cheindasitiri yeWWT.
