Palladium recovery device for palladium-containing wastewater

The palladium recovery device comprises a raw water bucket, a reduction reaction tank, separation equipment and a precision filter which are sequentially arranged, the top of the reduction reaction tank is externally connected with a dosing tank, a waste liquid lifting pump is arranged between the raw water bucket and the reduction reaction tank, and the reduction reaction tank is communicated with the separation equipment through the separation lifting pump. The separation equipment is communicated with the precision filter through the heavy liquid lifting pump, the separation equipment is provided with a clear liquid outlet, and the precision filter is provided with a filtrate outlet and a palladium metal outlet. A reducing agent with strong pertinence to palladium ions is added into the reduction reaction tank through the dosing tank, the reaction efficiency is high, the palladium ions are reduced into palladium metal, clear liquid and heavy liquid are separated by the separation equipment, the heavy liqui
