AI Technical Summary
In existing manganese zinc-containing sulfur wastewater treatment systems, when the wastewater composition fluctuates, the oxidant is preferentially consumed by low-valent sulfur, making it difficult to achieve targeted breakdown of metal complexes, resulting in poor treatment stability.
By employing a dynamic gradient monitoring unit, a spatiotemporal decoupling complex-breaking unit, an in-situ air flotation separation unit, and an adaptive iteration unit, a water quality state matrix is constructed to identify the spatiotemporal distribution characteristics of free sulfides and coordination complexes. Targeted complex-breaking oxidation is then performed, and in-situ capture is achieved using flocculants and microbubbles, thus realizing the stable release and separation of heavy metals.
It improves the utilization efficiency of oxidant, ensures the release and capture efficiency of heavy metals and the continuous operation stability of the system, and reduces the ineffective consumption of oxidant and the re-complexation of heavy metals.
