Iyo coagulation nzira yekurapa kwepapapermaking tsvina inoda kuwedzerwa kweimwe coagulant, iyo inowanzonziwo decolorizing flocculant yekugadzira mapepa tsvina. Nekuda kwekuti coagulation sedimentation inogona kubvisa zvakamira zvakamira mumvura yetsvina, kemikari sedimentation inogona kudzima.
Naizvozvo, huzhinji hwehutsvina, colloids uye zvinosvibisa mumvura yetsvina zvinogona kudonha uye kusanganiswa nekuwedzera iyi kemikari yekunaya kwemvura kune coagulation sedimentation tank, kuitira kuti iwane mhedzisiro ye decolorization uye destabilization, uye tsvina ichave yakajeka. Inowanzo shandiswa decolorizing flocculants inonyanya kusanganisira mapolymer flocculants uye microbial flocculants, uye mapolymer flocculants anosanganisira synthetic organic polymers, inorganic polymers, uye zvakasikwa organic polymers. Zviri pachena kuti decolorizing flocculantyekugadzira mapepa mvura yetsvina ndeye synthetic yakakwira molecular polymer.
Mvura yakaraswa inowanzogadziriswa ne: skrini → kugadzirisa → sedimentation kana kutenderera kwemhepo → A/O kana kubata oxidation → yechipiri sedimentation tank → kuburitsa. Iyo decolorizing flocculant inoshandiswa mune sedimentation tangi, uye ine hunhu hwekushanda nyore, kukwirira kubviswa kweCOD, uye inogona kudzivirira kusvibiswa kwechipiri.
Kune marudzi akawanda emvura yakaraswa muindasitiri yemapepa. Kunyangwe iri mvura yakaraswa yemusangano wekugadzira, tekinoroji yekurapa inoshandiswa ichave yakasiyana. Nekudaro, iyo nzvimbo imwechete yemvura inoraswa iyi yakakwira COD, yakakwira chroma, decolorization uye kudzikiswa kweCOD, saka vanogona kungogadziriswa ne decolorizing flocculants yekugadzira mapepa emvura yetsvina, uye vobva vabatirana nematanho akasiyana kubvumira mabhizinesi ekudzokorodza mvura kushandisa kana kusangana. discharge standards. Ita inline. Kana iyo mhando yemvura yakaraswa uye maitiro ekurapa akasiyana, ane hukama nedosi uye sarudzo yemhando ye decolorizing flocculant. Naizvozvo, zvinokurudzirwa kuitisa diki sampuli kuyedza usati waishandisa pamushini kuona iyo modhi uye dosage (zvizhinji zvezvigadzirwa zvedu zvine.mahara samples, kuitira kuti ipe data rakanyatsojeka uye vimbiso iri nani yekushandisa pane-saiti.
Komisheni yedu inofanirwa kunge iri yekupa vatengi vedu nevatengi nemhando yepamusoro uye zvigadzirwa zve100% Yekutanga Fekitori China Yakagadzirira Kutumira Zvakawanda Shandisa Chitosan, Silicone Defoamer, Mvura Decoloring Agent,Mvura Kurapa Makemikari, Aerobic Bacteria, Agent Anaerobic, Bacteria Agent, Halotolerant Bacteria, Phosphorus Bacteria Agent, Denitrifying Bacteria Agent, Polyaluminium Chloride, PAC, decoloring agent, Polyacrylamide, Polyacrylamide Powder, Powder, Polyfloriation yemvura, Polyfloriation yeAnticuhlo zvivako zvine vashandi vanopfuura 100. Saka isu tichavimbisa nguva pfupi yekutungamira uye yakanaka yemhando vimbiso.
100% Yekutanga Fekitari, Kambani yedu inoona kuti kutengesa hakusi kungowana purofiti chete asi zvakare kufaridzira tsika yekambani yedu kupasirese. Saka isu tiri kushanda nesimba kukupa iwe sevhisi yemoyo wese uye tichida kukupa iwe mutengo unokwikwidza zvakanyanya pamusika.
