Pelan rawatan enapcemar penyaduran dan pemulihan logam

Mengambil tiga jenis sampel enapcemar penyaduran yang dihantar oleh pelanggan sebagai contoh, cadangan rawatan disediakan daripada eksperimen.
Selepas pensampelan dan larut lesap, keputusan makmal tiga set larutan sampel diperolehi. Mereka adalah sampel 1, sampel 2, dan sampel 3. Kandungan ion logam berat seperti nikel, kobalt, mangan, magnesium, zink, besi, tembaga, kromium, memimpin, kalsium, etc. dalam larutan suapan dikesan berbeza. Ion logam berat ini adalah komponen utama enap cemar penyaduran dan mempunyai kemudaratan yang besar kepada alam sekitar.
Berdasarkan situasi pengesanan cecair bahan, kami boleh menyediakan pelan rawatan berikut:
1 # pelan pemprosesan sampel
Kemunculan sampel 1 adalah hijau, dan selepas pemeriksaan, kandungan logam utama ialah nikel, manakala kandungan logam yang lain agak rendah. Selepas melarutkan pepejalnya, nilai pH boleh diselaraskan. Seterusnya, use low concentration P204 for impurity removal, extract Fe, Cu, Zn, Mn, Cr from the system, and extract a small amount of Pb. Seterusnya, the raffinate was saponified using DY319 extractant, and the calcium and magnesium in it were washed away with water. Then, reverse extraction was carried out to obtain pure nickel ions.
2 # pelan pemprosesan sampel
Kemunculan sampel 2 is dark green, dan selepas pemeriksaan, kandungan logam utama ialah nikel, besi, and chromium. Pertama sekali, the Fe and Cr ions in the feed liquid should be pre-treated to remove them. Then, P204 extractant can be used to remove impurities, remove impurities such as Ca, Mg, Cu, Zn, etc., and perform reverse extraction. Seterusnya, use DY319 extractant for saponification and extraction of nickel, wash the calcium and magnesium ions in it with water, and then perform reverse extraction to obtain nickel ions.
3 # Sample Processing Plan
Kemunculan sampel 3 is black, and upon inspection, its main metal content is copper, besi, and chromium. Pre treatment is also required to remove Fe and Cr ions from it. Seterusnya, use DY988N for copper extraction electrolysis. For the raffinate, it can be directly added to the 2 # sample treatment and processed together.
Due to the similar metal content in several samples, only the difference in content, it is recommended to mix them all together for systematic treatment in large-scale production. This can use a set of process flow to treat all electroplating sludge and avoid repeated investment.
The significance of electroplating sludge treatment
If electroplating sludge is not properly treated and discharged, it will cause serious pollution to the environment. By using different treatment methods based on different component contents, the beneficial components of electroplating sludge can be effectively separated, recycled, and reused, which not only saves resources but also reduces environmental pollution. Although the investment in this recycling facility is significant, it is still significant in the long run. Especially for countries in Southeast Asia, Afrika, and South America, which used to have better natural environments, government funding is now needed to support early investment in this environmental protection industry, in order to protect people’s livelihoods and promote sustainable economic development. Invest early and benefit early.

Produk utama kami pengekstrak logam dan penggunaan seperti di bawah:

1. P204 (D2EHPA atau HDEHP) Ini digunakan untuk langkah pertama untuk membuang kekotoran untuk bijih nikel laterit.
2. DY319 pengekstrak bersama pengekstrakan nikel kobalt kecekapan tinggi, boleh mengeluarkan nikel dan kobalt bersama-sama daripada bijih laterit nikel atau elektrolit bateri Litium. Ini adalah langkah kedua untuk bijih nikel laterit.
3. DZ272 Pengekstrak pengasingan kobalt nikel, ia boleh mengeluarkan kobalt daripada larutan nikel kobalt, kemudian tinggalkan nikel tulen. Ini adalah langkah ketiga untuk bijih nikel laterit.
4. DY377 pengekstrak pemisahan nikel dan berlian yang cekap.
5. DY366 pengekstrak kobalt nikel termaju baharu.
6. DZ988N/DZ973N/DZ902 reagen pengekstrakan pelarut kuprum.
