Nyaya yekushandisa yekuburitsa mvura kubva kukambani yemishonga yekuChina muShanghai. MuPudong New Area, Shanghai Traditional Chinese Medicine Decoction Pieces Co., Ltd., kambani inotarisa pakugadzira mishonga yechivanhu yekuChina uye kutenga mishonga yekuChina, inorapa mvura yakasviba uye tsvina yemumba inogadzirwa nemabasa ayo ezuva nezuva kuburikidza nenzvimbo yekuchenesa tsvina yakazvivakira. Tsvina yakacheneswa inorasirwa munetwork yemapaipi etsvina emuguta pachiyero chinosvika 40.3 cubic metres pazuva, uye mitemo yekuburitsa mvura inotevera zvakanyanya "Comprehensive Sewage Discharge Standard" (DB31/199-2018). Kuti ive nechokwadi chekutevedzera mitemo, kambani iyi inoshandisa manejimendi yenguva dzose yenzvimbo dzemvura, uye inoshanda pamwe chete nekutarisa nguva dzose nekutarisira kwePudong New Area Water Affairs Bureau neUrban Management Administrative Law Enforcement Bureau.

Mukugadzirwa kwezvidimbu zvemishonga yechivanhu yeChinese, kubudiswa kwemvura yakasviba idambudziko rezvakatipoteredza risingafaniri kufuratirwa. Mvura iyi yakasviba inonyanya kubva mukusuka, kugadzirisa, kubvisa uye zvimwe zvinosanganiswa nemishonga, izvo zvinogona kunge zvine huwandu hwakawanda hwezvinhu zvinosvibisa zvipenyu, zvakaita semafiber emiti, mapuroteni, shuga nezvimwe zvinhu zvinonyunguduka zveorganic. Kana zvinhu izvi zveorganic zvapinda mumvura, zvinodya okisijeni yakanyungudutswa mumvura, zvichikonzera kufa kwezvisikwa zvemumvura, zvichikanganisa kuenzana kwezvakatipoteredza, uye zvichitokanganisa hutano hwevanhu kuburikidza nekudya.

Saka, zvakakosha kutarisa nekubata mvura iyi yakasviba zvinobudirira. Kudiwa kwemakemikari eoxygen (COD) ndiyo nzira huru yekuyera huwandu hwezvinhu zvipenyu mumvura yakasviba. Nekuyera COD, TCM Decoction Pieces inogona kuyera huwandu hwezvinhu zvipenyu mumvura yakasviba, nokudaro ichiongorora kushanda kwemaitiro ekurapa mvura yakasviba. Semuenzaniso, kana kukosha kweCOD kwakanyanya, zvinoreva kuti zvinhu zvipenyu mumvura yakasviba hazvina kuderera zvakakwana, uye maitiro ekurapa anofanira kugadziriswa, sekuwedzera matanho ekurapa kwebiological kana kugadzirisa nzira dzemakemikari, kuve nechokwadi chekuti mvura yakasviba inosangana nezvinodiwa zvakatipoteredza isati yaburitswa. Danho iri haringobatsiri kambani chete kushanda zvinoenderana nezvinodiwa, asiwo rinoderedza zvakanyanya njodzi yekusvibiswa kunzvimbo dzakakomberedza mvura.

Pamusoro pezvo, mvura yakasviba inewo huwandu hwakati hweammonia nitrogen nephosphorus, izvo zvinonyanya kuwanikwa mukugadzirwa kwezvinhu zvekurapa. Ammonia nitrogen inogona kubva mukuputsika kwemapuroteni, nepo phosphorus inogona kubva muzvinhu zvechisikigo zviri mumishonga kana mishonga yakawedzerwa. Kutarisa izvi zvakakosha pakudzora kusvibiswa mukugadzirwa. Semuenzaniso, nekutarisa huwandu hweammonia nitrogen munguva chaiyo, makambani anogona kugadzirisa maitiro ekusuka nekubvisa zvinhu zvekurapa kuti aderedze kuburitswa kwenitrogen; Saizvozvowo, kudzora kuburitswa kwephosphorus kunogona kubatsira kudzivirira kupararira kwemvura uye kuora kwemhando yemvura nekuda kwekuwanda kwealgae.

Pamwe chete, matanho aya ndiwo musimboti wekudzora kugadzirwa, zvichiita kuti masisitimu ekurapa mvura yakasviba ashande zvakanaka. Kuti ive nechokwadi chekuti mvura inobuda inosangana nezvinodiwa zvekuchengetedza nharaunda munyika nemunharaunda, Chinese Medicine Decoction Company yakatenga chishandiso chekuongorora hunhu hwemvura chakagadzirwa neShanghai Boqu Instrument Co., Ltd. kuti ivandudze maitiro ekugadzira uye kuderedza kugadzirwa kwezvinosvibisa nekutarisa zvinhu zvakaita seCOD, ammonia nitrogen uye phosphorus mumvura yakasviba munguva chaiyo. Kuburikidza nekuedza uku, kambani haingogone kudzivirira kusvibiswa kwenharaunda chete, asiwo kusimudzira mufananidzo wayo wemutoro wekambani uye kuwana budiriro inoenderera mberi. Pakupedzisira, kutonga kwakasimba kwekutevedzera nharaunda ndiyo chete nzira iyo indasitiri yemishonga yechinyakare yeChinese decoction piece piece kuchengetedza nharaunda neutano hweveruzhinji.
