AI Technical Summary
Existing aquaculture wastewater treatment technologies suffer from low treatment efficiency, easy generation of secondary pollution, short action cycle, and high toxicity to aquatic organisms, making it difficult to achieve efficient and stable in-situ remediation.
The treatment agent, composed of hydroxylated montmorillonite, modified zeolite powder, diatomaceous earth-supported iron-copper composite particles, chitosan-sodium alginate composite microspheres, and disodium EDTA, achieves efficient removal of COD, ammonia nitrogen, total phosphorus, and heavy metals through synergistic adsorption and catalytic degradation, combined with a slow-release carrier.
It achieves efficient and long-lasting removal of COD, ammonia nitrogen, total phosphorus and heavy metals, with an action period of more than 30 days. It causes no secondary pollution, is non-toxic to aquatic organisms, significantly reduces treatment costs, and promotes the growth of aquatic animals.
