Te Taipitopito Kaupapa

Ko te otinga kotahi-mutu e tukuna ana e Jiarong e tika ana mo te riihi me etahi atu maimoatanga wai para. He pai te otinga mo te kaihoko i Brazil ki te whakaheke i te rerenga wai para. Ano hoki, i tutuki te kounga o te kuhu ki te paerewa tuku para paru o te rohe.

Te waahanga kaupapa

Ko te 1.5 L/s te rerenga rerenga teitei.

Ko te nui o te rerenga mo te maimoatanga wairewa mo tenei hoahoa ka taea te 5.4 m³/h, 120m³/h ranei, i runga i nga hiahia a te kiritaki.

Ko te kaha maimoatanga hoahoa he 250 m ³ /d me te 90 % te kaha whakahaere.

He kaupapa maimoatanga whawhati tata a Shenyang Daxin

Te waahanga kaupapa

Tauine nui: 0.94 miriona m ³   te rīwai, te kaupapa maimoatanga ohorere rīwai nui rawa atu i te ao.

He wero nui: tino kaha te kawe hiko, te kukū o te haukinia me te tino pai o te tukunga o te wai.

Mahere kaupapa kaha:

E 800 tone/d ka puta i roto i te 1 marama

E 2,000 tana/d ka puta i roto i te 3 marama

He tino pai: 18 nga huinga o nga punaha ipu Jiarong i whakaritea. I tutuki katoa te kounga o te rewharewha ki te paerewa tuku para wai o te rohe.

Tauira Biz Hou: Ka whakapau moni a Jiarong ki te whakahaeretanga o te kaupapa me te utu i te utu maimoatanga mo ia tana o nga wai para kua rongoatia.

Te kounga o te wai mata:

NH ₄ -N: 2,500 mg/L

COD: 3,000 mg/L

EC: 4,000 μs/cm

Te kounga parawai:

NH 3 -N 5 mg/L

COD 60 mg/L (ka tutuki i te paerewa motu GB18918-2002 Class-A)

Te tukanga maimoatanga :

Pretreatment + E rua nga wahanga DTRO + HPRO + MTRO + IEX

Wataka o te kaupapa

Maehe 30 ^th , 2018: Kua hainatia te kirimana
