AI Technical Summary
Existing wastewater treatment systems for blast furnace waste heat power generation lack systematic integration and functional optimization, resulting in suspended solids and metal impurities in the wastewater entering the collection tank directly without pretreatment, causing equipment blockage and corrosion, and affecting treatment efficiency and safety.
An integrated wastewater treatment device was designed, including a wastewater collection unit, a pretreatment unit, and a reverse osmosis treatment unit. It employs a media filter tank, an ultrafiltration tank, a security filter, and a reverse osmosis membrane housing, combined with a filter basket driven by a dual-axis motor and a permanent magnet core rod, to achieve multi-stage filtration and impurity removal. The waste heat is used to preheat the reverse osmosis feed water through a plate heat exchanger, and a nitrogen sealing layer is provided to maintain water quality stability.
It achieves closed-loop treatment of wastewater throughout the entire process, improves the efficiency of impurity removal, reduces the risk of equipment blockage, extends the stability of system operation and equipment life, and reduces operating costs.
