Nkhani Yogwiritsira Ntchito Malo Otulutsira Magazi a Kampani Yopangira Zidutswa Zamankhwala Achi China ku Shanghai

Malo owunikira: Malo otulutsira madzi m'malo oyeretsera zinyalala a kampaniyi

Zinthu Zogwiritsidwa Ntchito:

- CODG-3000 Online Automatic Chemical Oxygen Demand Monitor

- NHNG-3010 Ammonia Nayitrogeni Yowunikira Yokha Paintaneti

- TPG-3030Chowunikira Chokha Chokha cha Phosphorus Paintaneti

- pHG-2091Chowunikira cha pH Paintaneti

Kugwiritsa ntchito njira yotulutsira madzi kuchokera ku kampani yotulutsa mankhwala ku China ku Shanghai ku Pudong New Area, Shanghai Traditional Chinese Medicine Decoction Pieces Co., Ltd., kampani yomwe imayang'ana kwambiri pakupanga mankhwala achikhalidwe aku China komanso kupeza mankhwala aku China, imatsuka madzi otayira ndi zinyalala zapakhomo zomwe zimapangidwa ndi ntchito zake za tsiku ndi tsiku kudzera mu malo oyeretsera zinyalala omwe amapangidwa okha. Zinyalala zomwe zimatsukidwa zimatulutsidwa mu netiweki ya mapaipi a zinyalala za m'matauni pamlingo wokwana ma cubic metres 40.3 patsiku, ndipo miyezo yotulutsira madzi imatsatira mosamalitsa "Comprehensive Sewage Discharge Standard" (DB31/199-2018). Pofuna kuonetsetsa kuti zikutsatira malamulo, kampaniyo imagwiritsa ntchito kayendetsedwe ka nthawi zonse ka zinyalala, ndipo imagwirizana ndi kuyang'anira nthawi zonse kwa Pudong New Area Water Affairs Bureau ndi Urban Management Administrative Law Enforcement Bureau.

Pakupanga zidutswa za mankhwala achi China opangidwa ndi mankhwala achikhalidwe, kutulutsa madzi otayira ndi vuto la chilengedwe lomwe silinganyalanyazidwe. Madzi otayirawa amachokera makamaka kutsuka, kukonza, kuchotsa ndi kulumikizana kwina kwa zinthu zamankhwala, zomwe zingakhale ndi zinthu zambiri zoipitsa zachilengedwe, monga ulusi wotsalira wa zomera, mapuloteni, shuga ndi zinthu zina zosungunuka zamoyo. Zinthu zachilengedwezi zikalowa m'madzi, zimadya mpweya wosungunuka m'madzi, zomwe zimapangitsa kuti zamoyo zam'madzi zife, kusokoneza chilengedwe, komanso kukhudza thanzi la anthu kudzera mu unyolo wa chakudya.

Chifukwa chake, ndikofunikira kuyang'anira ndikusamalira bwino madzi otayira awa. Kufunika kwa mpweya wa oxygen (COD) ndi muyeso wofunikira wa kuchuluka kwa zinthu zachilengedwe m'madzi otayira. Poyesa COD, TCM Decoction Pieces imatha kuyeza kuchuluka kwa zinthu zachilengedwe m'madzi otayira, potero kuwunika momwe njira zochizira madzi otayira zimagwirira ntchito. Mwachitsanzo, ngati mtengo wa COD uli wokwera kwambiri, zikutanthauza kuti zinthu zachilengedwe m'madzi otayirawo sizinawonongeke mokwanira, ndipo njira yochizira iyenera kusinthidwa, monga kuwonjezera magawo ochizira achilengedwe kapena kukonza njira zochizira mankhwala, kuti zitsimikizire kuti madzi otayirawo akukwaniritsa miyezo ya chilengedwe asanatulutsidwe. Gawoli silimangothandiza kampaniyo kugwira ntchito motsatira malamulo, komanso limachepetsa kwambiri chiopsezo cha kuipitsidwa m'madzi ozungulira.

Kuphatikiza apo, madzi otayira alinso ndi nayitrogeni ndi phosphorous ya ammonia, zomwe zimachokera makamaka ku njira yopangira zinthu zamankhwala. Nayitrogeni ya ammonia ingachokere ku kuwonongeka kwa mapuloteni, pomwe phosphorous ingachokere ku zosakaniza zachilengedwe zomwe zimapezeka mu zitsamba zamankhwala kapena mankhwala ena owonjezera. Kuyang'anira magawo awa ndikofunikira kwambiri poletsa kuipitsidwa kwa zinthu popanga. Mwachitsanzo, poyang'anira kuchuluka kwa nayitrogeni ya ammonia nthawi yeniyeni, makampani amatha kusintha njira zotsukira ndi kutulutsa zinthu zamankhwala kuti achepetse kutulutsidwa kwa nayitrogeni; Mofananamo, kuwongolera kutulutsa kwa phosphorous kungathandize kupewa kufalikira kwa madzi m'madzi ndi kuwonongeka kwa ubwino wa madzi chifukwa cha kuchuluka kwa algae.

Pamodzi, njira izi ndi maziko a kayendetsedwe ka ntchito, kuonetsetsa kuti njira zochizira madzi otayidwa zikugwira ntchito bwino. Pofuna kuonetsetsa kuti madzi otayidwawo akukwaniritsa miyezo ya dziko lonse komanso yakumaloko yoteteza chilengedwe, kampani ya Chinese Medicine Decoction Company idagula chida chowunikira ubwino wa madzi pa intaneti chopangidwa ndi Shanghai Boqu Instrument Co., Ltd. kuti chiwongolere njira yopangira ndikuchepetsa kupanga zinthu zoipitsa poyang'anira magawo monga COD, ammonia nitrogen ndi phosphorous m'madzi otayidwa nthawi yeniyeni. Kudzera mu izi, kampaniyo singangopewe kuipitsa chilengedwe, komanso kukulitsa chithunzi chake cha udindo wa kampani komanso kukwaniritsa chitukuko chokhazikika. Pamapeto pake, kuyang'anira mosamala malamulo azachilengedwe ndiyo njira yokhayo yomwe makampani opanga mankhwala achi China ochizira mankhwala azikhalidwe amatetezera chilengedwe ndi thanzi la anthu.
