A pharmaceutical wastewater treatment device. The device comprises an air floatation tank (1), a conditioning tank (2), a strengthened hydrolysis acidification tank (5), an efficient methane production tank (8), an anoxic tank (11), an aerobic tank (12), and a coagulation sedimentation tank (15) that are sequentially connected, and further comprises an acid loading tank (3), an alkali loading tank (5), a micron-scale calcium silicate loading tank (6), a control unit (19), and a power supply. The strengthened hydrolysis acidification tank (5) is provided with a flow guide tube at the top, a fixed packing (7) at the middle part, and a micron-scale calcium silicate loading duct and a uniform water distributor (18) at the bottom. The efficient methane production tank (8) is provided with a combined packing (9) at the middle part, a fixed soft packing (10) at the upper part, and a uniform water distributor (18) at the bottom. Also disclosed is an operation method for the pharmaceutical wastewater treatment device. |
